Computer keyboard failure a solution how to do the computer keyboard can not be used

Leave a comment

Heck, many computer novices friends would ask me how the failure of the keyboard ? Not press the number keys on the keyboard , or the failure of part of the keyboard keys . Around these more common computer keyboard failure , computer white matter , editor skies rain system for everyone to be introduced , so that we can identify the cause of the failure of the keyboard as well as solutions .
Keyboard failure have more variety , here are some common keyboard failure phenomenon and solutions.
A : the numeric keypad on the keyboard failure
This is the lowest level error will often make a lot of new friends , usually large desktop keyboard , causing the keyboard numeric keypad ( 0123456789 ) failure of most of the key reasons is that we closed the numeric keypad , you can see Numlock key is turned on , the corresponding there is a light above the numeric keypad , press the Numlock lights above the key that opens the numeric keypad.
Some notebook novice friends often ask why I’m right part of the letter keys laptop keyboard is indeed break out numbers instead of letters, very tangled ! In fact, this is because the numeric keys and alphabet keys laptop binding exists , when opening the numeric keypad, letter keys are arranged on the right part of the number keys , mainly because of less laptop keyboard , the intelligent switching factory settings . Solution is as follows :
If only the keypad is locked , then press and hold the fn + Numlk key to switch to , and vice versa. There are some new friends often do not know the wrong letters playing out all uppercase letters , this is because the key function opens the uppercase letters , canceled only need to press the “Caps Lock” key to switch to normal.
Two : part of the keyboard keys on the keyboard failure, this is no regular key failure
Key failure caused by keyboard part , this situation is most computer keyboards internal circuit board failure , this phenomenon is usually because the circuit board or conductive plastic on the dirt , which makes it impossible to properly switched between the two. Other factors are also possible, such as: keyboard plug is damaged , line problems, damage to the motherboard , CPU is not working properly , etc., but not the main reason. The former you can try the following methods to resolve them, and the latter is generally related to computer failure or malfunction keyboard is not the scope of this .
1 . Disassemble the keyboard. Note that when you open the keyboard , be sure to button surface ( that is, we operate side ) down , board up , otherwise conductive plastic may have come off on each key , giving you repair trouble.
2 . Open circuit boards, circuit boards are generally made ​​of soft plastic film , buttons engraved with cable , with a concentration of more than 97 % alcohol cotton ( 75% of medical alcohol cotton can, because I had used , but the most good cotton with a high concentration of alcohol ) and gently scrub two times on the circuit board . For key failure to take care of part of the line a few times .
3 . View key failure conductive plastic parts , if the above accumulated a lot of dirt , then use the same alcohol scrub. Assuming conductive plastic is damaged , then I suggest that you can not commonly used conductive plastic buttons on the change to the damaged part , although this “shattering ” initiative not allow the keyboard to play out all the features , but the most At least you can extend the life of common keys.
4 . Clear the keyboard in the corner of the dirt , tools available brush, small brush , etc., but pay attention to some of the action should be gentle .
5. Check whether the module is soldered or welded sealing off , if you make the electric iron , it can repair welding work . Of course, this procedure applies only to make the electric iron on a friend , the friend will not be used , skip this step.
6. Installed keyboard. One thing to note here that we have to wait and then be clean and the alcohol evaporates . The best computer configuration network

If the above methods can not be resolved , we can then try to use what method of investigation :
Modify keyboard driver : Open through the ” My Computer” System Properties , select the Hardware tab : Open the Device Manager, we found that under Chinese Windows XP operating system , the default keyboard driver is the “standard 101 / 102 key or Microsoft Natural PS / 2 keyboard . ”
1 Right-click and select Update Driver Hardware Update Wizard appears : Select ” Install from a list of specific location (Advanced ) ” and click “Next “, select ” Do not search I will choose the driver to install. ”
Click “Next” to enter the ” Select install this hardware device drivers ” on page remove the check box ” Show compatible hardware ” before the tick . In the ” Standard Keyboard Model ” column select click “Next ” pop-up ” Update Driver Warning ” point ” is .” “Confirm Installation ” window continues to point ” is .”
2 . Complete the Hardware Update Wizard. Restart the computer.
Modify the registry : Click the “Start” menu , click ” Run”, type “regedit”, open the registry, enter “HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Control \ Keyboard Layouts”, there are many children , I have found through observation , to ” 0804 ” at the end are Simplified Chinese input method. Open the “E00E0804″, can be seen on the right of children there “Layout File” subkey, double-click to open the item , the ” Value data ” in the “kbdus.dll” to “kbdjpn.dll”, ” OK” available . And so on , can be all to ” 0804 ” at the end of the subkey “Layout File” all changed “kbdjpn.dll”, will be chosen specifically according to their common input method. Then restart the computer just fine !

If the above methods do not solve , then it may be a hardware failure, the most common hardware failure is the keyboard , the keyboard inside the wrench is oxidized , resulting in disconnection , etc. , we can try another keyboard , the vast majority can solve the problem, of course, there are very few emerging since the keyboard plug is damaged , circuit problems, damage to the motherboard , CPU is not working properly , these we need to take the place of professional service under specific detection .

When Should I Consider When Buying a Dell pc764 battery

Leave a comment

When choosing a Dell pc764 battery, you should first make sure that it is compatible with your computer, and then consider the materials it’s made out of. It’s also best to look at the power rating and service life, since these have a large impact on its performance and lifespan. Additionally, you may want to consider whether you want a brand name or generic replacement, as well as whether you want a new battery or a refurbished one. Whichever one you choose, you should also look at any warranties offered, and make sure that it complies to safety standards.

Compatibility

The first thing to look for when buying a new laptop battery is compatibility with your computer. Most are made to work with specific models of computers, and have this information listed in their product descriptions. To make sure that one will work with your computer, you’ll need to know the make and model number of your laptop; if you don’t know this offhand or don’t have the necessary paperwork, check the inside of your laptop’s battery compartment while it is off and unplugged. You may also find the part number of the battery, located on its casing.

Materials

You should also consider the material that the battery is made out of: Nickel Cadmium (NiCad), Nickel Metal Hydride (NiMH), Lithium Ion (LiON), or Lithium Ion Polymers (Li-Poly). NiCad batteries are largely obsolete, since they are very heavy and don’t last very long. NiMH batteries last longer than NiCads, but significantly shorter than LiONs and Li-Polys. They also weigh more, and have the “memory effect,” which causes them to lose the ability to fully recharge.

Generally speaking, LiON and Li-Poly batteries are the best choice, as long as they’re compatible with your laptop, since they are light, last longer than NiMHs, and are about a third lighter. They also charge more quickly, and are also more environmentally friendly. Regardless of which type of laptop battery you end up getting, you should make sure that the cells are manufactured in such a way that they meet international standards of laptop battery safety, like those designated by Underwriters Laboratories (UL).

Capacity

The capacity, or power rating is another important consideration. This is the amount of power that the battery can produce, and is usually written in milliamperes (mAh). The greater the capacity, the longer the battery can run before it needs to be recharged, so look for the highest mAh number. Most new ones are rated to at least 5,000 mAh.
Service Life
Like other technological products, laptop batteries have a designated service life — the length of time that they’re expected to work optimally. This is usually written in terms of cycles, with one cycle consisting of completely running the battery out, and then completely charging it again. Most are are able to go through between 300 and 1,500 charging cycles, and can be used after the maximum cycle count is reached, but may not hold a charge as well. Some computers come with a cycle counter built in, but there is free cycle counting software is also available online for download.

Branded vs. Unbranded

You may additionally want to consider whether you want to buy a brand name laptop battery, like the one your laptop came with, or a generic replacement one. Many brand companies and companies that make generic batteries get their components from the same manufacturers, so it may not make a huge difference, but some brand name versions meet more rigorous safety standards than generic ones, and some do use different, higher quality components. Also, some brand name versions come with better warranties than generic ones. Branded batteries do tend to be more expensive than generic ones though, so if you compare a brand name laptop battery and a generic one and find them to be largely similar, then you may want to go with the generic one.

New vs. Refurbished

Besides the issue of branding, you should also think about whether you want a new Dell pc764 battery or a refurbished one. Though some refurbished ones are very good and are often much cheaper than new ones, it’s a little risky to buy refurbished, since you don’t really know how old the battery is, and it may die suddenly. Also, many refurbished batteries don’t come with very good warranties, so it may be worth it to just get a new one, especially if you use your laptop a lot.

Depth analysis of dell m1210 battery

Leave a comment

The leading control chip charge control Dell m1210 battery charging process. Lithium-ion battery charging process is divided into two phases, constant current fast charge phase (the battery indicator light yellow) and voltage current phase (it indicator light flashes green. Constant current fast charge phase, the battery voltage is gradually increased on the standard battery voltage, then underneath the control chip into your constant voltage phase, the voltage is not going to rise in order to ensure that no over-charge, current battery, as well as rising gradually weakened to 0, plus the final charge.

Statistics chip power consumption by recording the discharge curve (voltage, current, time) can calculate the sample Dell m1210 battery power, and this we find about inside Battery Information wh. Values. The lithium-ion batteries in repeated use, the making curve changes, if your chip have been no opportunity to over again read out a total discharge curve, and that is calculated out of electricity that isn’t accurate. So we should instead calibrate the battery charge and discharge deep chips.
How to correctly charge laptop?

1, You don’t need to ensure each time put END electric charge;

2, time to complete a protection circuit to manipulate the depth of charge and discharge it to fix the stats, nonetheless it will never boost your Dell battery’s actual capacity;

3, the long-term with no battery, really should be positioned in a very good destination to weaken a unique internal passive reaction rate;

4, the protection circuit can also be able to monitor the Dell battery self-discharge, long-term without worrying about battery, must be loaded with some power stored in the battery to prevent excessive discharge caused by excessive discharge damage.

In reality, it isn’t an excessive amount of to take into account the employment of attention, put simply is taken into account is just not much use. Dell m1210 battery power can be used often times, perhaps more through the difference within the output of it itself, individual differences, instead of use. Select a good reputation laptop brand is undoubtedly one’s destiny by using long-life battery one of many guarantees, usually a laptop within the life of 3-5yrs, and also the battery is additionally about three years, hence the require to use , and without too much to resolve the battery usage.

Save costs with proper dell latitude e6400 battery care

Leave a comment

Imagine you have just bought your laptop, and before long the battery starts to weaken at. Let it not come to that point, because the most important guarantee for a long service life is a proper battery care. The following tips should help you get the most out of your dell latitude e6400 battery. This not only saves time and money but also a lot of trouble.

Tip 1: Battery care begins directly after purchase
If you encounter when buying your laptop, the battery is fully charged, you should do so in any case. Discharge the battery as it will lose about 20% of its capacity. Download it directly instead of a full 100% capacity performance.

Tip 2: battery maintenance during system operation
Use the notebook rather stationary and often work in network operation, we recommend the Dell battery at this time to remove from the notebook. The reason is that the battery even if it is not used, but always lose a little energy and is due to the operation of the outlet fully recharged. This constant low charge-discharge cycles (partial loads) can not cause significant damage to the dell latitude e6400 battery. Another reason originates in the rapid evolution of heat generated during the continuous operation of the outlet. Here is the danger of overheating, which can lead to a rapid decrease in battery performance.

If you only briefly on the circuit to work, you must of course not always take out the battery. However, you should be very soon that the battery heats up, remove it immediately.

Note: If you recharge the Dell battery, take out and not use it, it loses some of his time with the stored charge, which, depending on age, model and temperature for about 5 – up 20% in the month. This process is called self-discharge. To avoid that the battery is not fully discharged, run about a 1 – by 2 times a month, a charging and discharging.

Tip 3: The right to charge and discharge
Do you need the notebook for frequent mobile use and the battery is therefore in frequent operation is the right to charge and discharge is essential. How do you recommend the Dell battery once a week to the remaining capacity of 5% “exploit” and then recharge to 100% charge capacity. Do not use the notebook on battery power only, otherwise shorten the life span.

Tip 4: On the right temperature eighth

If your battery is stored for a short time, we advise them that we are at room temperature of 20 – 25 ° C do. Do you need the battery several months do not, it is recommended that in a dry cool place at 0 ° C storage. However, you should not forget the monthly charging and discharging. Recharge the dell latitude e6400 battery at the optimum temperature is around 20 ° C.

Tip 5: If the battery is getting tired …
If you notice that the performance of the battery is reduced significantly, we recommend using the battery for about 2 – to charge 3 times in a row and then unload (maximum 5%), this looks like a kind of “wellness” for the cells and increases the life . When used correctly, the dell latitude e6400 battery regains its full capacity. Laptop batteries have only a certain number of loading cycles. These vary depending on battery type 400-1000 charging cycles, which corresponds approximately to a period of 2 – 3 years.

How to fix dell mini 10 battery

Leave a comment

Notebook Battery aging is inevitable occurs, almost all repair methods are trial “deep cargo discharge” principle to facilitate the battery memory effect. But there is no denying the depth of the charge and discharge operation will not be good for the dell mini 10 battery itself, is a way to do this can not be. If battery life is only for the ten minutes to reduce, then to be taken to that method of operation. In addition, battery manufacturers have been optimized, there is no self-discharge increase again the depth of the battery capacity of the argument. But just when you need it is difficult, the depth of discharge, after all, every time the power consumption can not comprehend the same, I would advise you to help BatteryMon this professional software.

BatteryMon is particularly for the small Dell battery monitoring software, especially for those without built-in power management chips and software for the machine, it certainly helped a lot of great help. BatteryMon biggest feature is the discharge curve can be displayed and the installation will run automatically. A good performance of the DELL battery have a very regular discharge curve, as shown, is basically every time a grid probably down are the same. ACER battery AS07A32 If found, a very unusual beat, then it is necessary to repair the cell “deep cargo discharge”.

Secondly, the “deep cargo discharge” the basic method

Battery calibration is an effective way to deal with aging batteries, generally, each about a particular brand laptop battery calibration software. Recommended For example, IBM ThinkPad series of dedicated discharges software for all users on IBM laptop. But the program will be repeated three times to achieve optimal results. Download the software and the implementation of the relief is requested the system to create your installation CD. Use the installation CD to boot pcdos, unplug the power cord tips that relief will control the software to automatically discharge. When it was over notebook is shut down automatically, and then we can connect to the power source to recharge the name, the time control was repeated in 9 to 12 hours, 2 to 3 times.
Laptop battery for activation, we find the right key to unload software.

Unfortunately, when it is your laptop not a specific discharge software can click Close in the BIOS and Windows power management features, and then not all programs run in the event empty the Dell battery, then in the trunk of charge to about 80% So, after a few such repeated manual “deep cargo discharge.” Indeed, this approach aims for continuous low current discharge dell mini 10 battery the discharge state in our daily use are not achieved, the effect to make the fulfillment of this particular principle, the same software.

Do not use under normal circumstances, the battery, the battery life is also used, the shorter the life, the worse the battery life!

How to install a new CPU processor Fans

Leave a comment

To get started, shut your system down and flick the switch on the back of your power supply to “Off” (which can itself be accessed from back of your PC). As this is going to be a fairly elaborate endeavour, it’s a good idea to remove all cables from your computer and lay it down an an flat and well lit surface for easy access cpu processor fans.

Also, make sure to ground yourself on a metal object before proceeding (such as your radiator), and try to steer clear from carpets (and other objects that might charge you up again) for the time being.

1. Open your case from the side to get a good look at the insides of your PC. Many coolers require the installation of a backplate on the other side of your motherboard to stabilize cpu processor fans. If this applies to your model, you will likely have to remove the motherboard itself to reach the right spot – start by removing potential screws that might hold your graphics card in place. If not, jump to step 7.

2. While older models can be pulled out from their PCI slot without any further mechanisms, most modern graphics cards require you to pull a small plastic level on its side. Some may even be connected to your power supply directly with one or two 6-pin connectors. Unplug them and remove the card.

3. Next, look for the screws that are keeping your motherboard attached to the PC case. Simply, check the borders to find the lot of them (the last one is normally located just below your CPU in the middle). Try to loosen them all at roughly the same rate until they can be removed.

4. Unplug all cables connected to your motherboard that are interfering with the removal. If you aren’t sure whether or not you can reconnect them properly later on, its a good idea to make a photo while everything is still in place. Marked in our photo: The 24-pin and 4-pin power supply connectors and the SATA slots.

5. Typically, there are nine screws to be removed from ATX motherboards, though this may vary with other form factors. Make sure you got them all and put them someplace safe for the time being.

6. Carefully lift your motherboard out of the case. It’s up to you whether or not you want to remove all cables from the motherboard, as this might overcomplicate the re-installation for dexterous tinkerers. For maximum comfort, it’s obviously better to do so and to take the motherboard someplace else.

7. A close up of our old CPU cooler – already a bit dusty. Notice the small size of the fan blades.

8. Look for the small 4-pin cable that extends from the cooler to the motherboard. Gently waggle it off without bending the pins.

9. Next, you will have to remove the cooler itself. See if there’s a small lever at the side to push down. Depending on your respective model, the exact method of removal might differ. If there’s no lever to be found, you can typically find four push-pins at each corner.

10. After pressing down the lever, release the metal clamp from both sides of the cooler. If you are dealing with push-pins instead, try turning your motherboard around and see if your can squeeze the two halfes of each pin together in order to loosen it.

11. On the left: Our new “Scythe Mugen II” (about £35); on the right: The old boxed cooler.

12. As you will have noticed, your CPU is now finally brought to light. The greasy paste on top of it is a thermal compound that improves the heat conductivity between the CPU and the cooler, thus improving the cooling performance (air alone would be significantly less effective). Refrain from touching it and ignore it for now.

13. If your new cooler requires you the install a backplate onto your motherboard, turn it around and do so.

14. Additionally, take a look into the manufacturer’s manual and see if there are instructions as to how the cooler needs to be modified before being placed onto your respective socket. This typically includes assembling the mounting device in a particular fashion.

15. Attach the fan to the heatsink. This is often accomplished with the help of metal brackets.

16. Time to get back to the CPU. It is highly advisable to remove the rest of the old paste before applying a new dose. Carefully wipe the bulk of it away with a clean piece of cloth.

17. Next, take another piece of cloth and slightly moisten it with pure or rubbing alcohol (at least 70%+). Gently sweep the surface of the CPU with it a couple of times to remove all residues. Take care not to accidentally touch the surface, as this will likely leave greasy fingerprints.

18. Apply a tiny dose of fresh thermal paste – a bit smaller than the size of a pea – on top of your CPU and evenly spread it with the help a a strong sheet of paper (business cards will do). The idea is to thoroughly cover the whole surface while keeping the layer as thin as possible to ensure ideal cooling conditions.

19. If present, make sure to remove the plastic foliage covering the underside of your CPU cooler. Again, try not to accidentally touch the metal surface with your fingers after doing so.

20. Put all necessary backplate screws in place and rotate the cooler until it matches their position. Gently lower it onto the CPU, ideally without twisting it around too much once it is has made contact. Tighten the screws connecting the cooler to the backplate/motherboard.

21. Once the cooler is firmly connected to the motherboard, make sure it pushes the air out of the rear of your PC case to optimize airflow (whether you place the fan before or behind the heatsink is up to your model and preference).

22. As a final step, put your motherboard back into the PC case and reattach all necessary screws as well as the cables and PCI cards that you previously removed. Don’t forget to connect the cpu processor fans power plug to the 4-pin connector on the motherboard before closing it up again.

How to Replace Your Laptop Keyboard for HP

Leave a comment

If your laptop keys are sticky, or some of them are missing, or the keyboard isn’t working at all, you can usually replace the entire keyboard yourself for between $20 and $60. The operation isn’t as hard as you might think, and performing it has the advantage that you don’t have to remove and replace each key individually. Though every laptop is different, removing your hp laptop keyboard usually involves simply unsnapping a cover, removing a few screws, and disconnecting a cable.
If you’re up to the challenge, you can tackle this project in the comfort of your own home. Take care, though: A working laptop is a terrible thing to waste, and PCWorld accepts no responsibility for any damage to your machine that might occur if you try to take it apart. Furthermore, if duplicating our process requires actually opening your entire laptop–if, say, you have to remove anything more than a handful of screws–you should call a professional. And finally, before you do anything else, check to see whether the laptop is still under warranty. If it is, you may be able to get it replaced for free.

Find a Replacement Keyboard

The first step of the replacement process is to obtain the right keyboard for your laptop.  Make sure that the hp laptop keyboard you buy is for your laptop’s exact model number, which you may find printed on your screen bezel or on a label attached to the underside of the laptop. You can simplify your search further by specifying the keyboard’s part number, which you may be able to find on the laptop manufacturer’s website or by calling their support/service department.

Replacing the Keyboard

For more-precise instructions on how to replace your particular laptop keyboard than the general steps provided here, check online. There’s a small chance that your laptop is unique and has a very different replacement process from the standard one outlined here. Check with your laptop manufacturer and with the site where you bought the replacement keyboard to see whether they offer specific instructions for DIY repair. Some manufacturers provide service manuals with detailed instructions on a variety of servicing tasks; if not, try searching the Web for “how to replace keyboard” with your laptop’s model number.

Now let’s get started! Confirm that you purchased the appropriate replacement, by placing the new one on the laptop, and seeing if it appears to be the right shape and size. Next, gather your tools: a small Phillips screwdriver for removing the small screws, and a butter knife or other small, thin, flat tool for prying off any covers.

Make sure that the laptop is powered completely off: Unplug the power cord and take the battery out.

Usually a removable cover or trim piece offers access to the keyboard.

 

Examine the cover/trim piece that sits between the keyboard and the screen; it usually affords access to the keyboard. Check for and remove any screws that appear to be helping hold the cover piece on. Some pieces also cover the screen hinges, which may have small screws on their backs.

Before removing the cover, be aware that it may have a data cable on the back that’s connected to the laptop. This cable is important and usually doesn’t have much slack, so be very cautious when removing the trim piece that holds your laptop’s keyboard in place. You don’t want to rip the cable from the laptop and ruin the connector or the cable.

A data cable attached to the laptop may lie under the cover or trim piece.

 

When the cover is loose, gently remove the cover/trim piece with your bare hands; if necessary, carefully use a butter knife or other thin flat tool to pry it up. The cover should snap off fairly easily with a small amount of force–don’t use extreme force or you may break it. If it doesn’t seem to be coming off, recheck for any remaining screws that may be holding it on–even underneath the laptop–and remove them.

Once you’ve removed the cover/trim piece, set it aside. If it’s attached to the laptop via a data cable, carefully try to move it out of the way without damaging the cable. Then find and remove the screws holding the keyboard in place; there are usually two to five such screws, located along the top of the keyboard.

Two screws hold this laptop keyboard in place.

 

Before pulling the keyboard up, note that the back of the keyboard attaches to a data cable that in turn is connected to the laptop. This cable usually doesn’t have much slack either, so be very careful when pulling it up. It is crucial to avoid ripping the cable from the laptop and ruining the connector.

A small flat data cable on the back of the keyboard connects to the laptop.

 

Carefully pull the keyboard up (without ripping the data cable from the laptop) and unlatch the data cable connector, usually by flipping up the small latch on the connector. Next, remove the data cable and set the old keyboard aside.

Pick up your new keyboard, align it (without setting it down), and attach the data cable to the connector on the laptop, usually by inserting the flat cable as far as it will go and then flipping the small latch on the connector back down to grasp it. With the data cable connected, set the keyboard in place, being careful not to pull at or damage the cable in any way. Reinsert the screws to hold the keyboard down and reattach the cover/trim piece, which usually requires a little force to snap back into place. If you removed any screws from the cover earlier, reinsert those as well.

Once you’re done with these steps, you can reinstall your battery and boot up the laptop. If everything went smoothly, you should have a  hp laptop keyboard at a fraction of the cost of having a professional repair service do the work!

Leave a comment

Over time, the rechargeable batteries in a laptop wear down with repeated charging and discharging. Your usage patterns and habits can make a difference in how long it takes for the battery to wear down, though. Here’s how to avoid having to replace those costly samsung laptop battery as often.

1.Remove the battery pack from the laptop if you do not use your laptop for extended periods of time (a week or more).

2.Do not expose the battery to high heat. Do not leave your battery in your car in the summer. Hot batteries discharge very quickly.

3.Plug your laptop charger adapter into a UPS and not directly into a power outlet or surge protector.

4.If you have a nickel-metal hydride battery, completely drain and recharge the battery once a month to maximize its capacity to hold a charge.

5.Fully charge new battery packs before use. A new battery needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity.

6.For laptops that work as a desktop replacement, reinstall the battery every 3-4 weeks and allow it to discharge fully .

7.Do not leave a battery in a laptop while using an electrical outlet for long periods of time. This will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.

8.Adjust screen brightness. If you use Windows on your laptop, there is a Power Options option in Control Panel that helps you optimize power usage. You can set the laptop to become inactive when not in use for quite some time. It is also possible to adjust the display brightness on the laptop. This may allow prolonged battery life.

9.Program Overload. Run only the programs you are using at the time of use. Programs that run in the background use more system resources and drain laptop battery life.

10.Keep a spare battery: A good idea is to have a spare battery. Batteries are affordable these days and easily purchased online from electronics sites. Have at least one fully charged at all times for a quick battery change. Some laptops can run with two batteries. Some laptops are also compatible with external batteries that can be easily added when necessary.

If you do the above ten-point proposal. I think your samsung laptop battery will be more long-term use.
