How to install a new CPU processor Fans

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

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!

How to Extend the Life of samsung laptop battery

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.

Care of Camera Batteries NIKON D3100

The problem of excessive consumption by the battery, there are some special care requirements of the battery, but here are some general guidelines. can give your nikon d3100 battery more protection.

Storage. Don’t store batteries at high temperatures. Why? They can self-discharge a lot faster, which is why that flashlight stored in the hot car all summer has dead batteries. And some rechargeables can be permanently degraded or destroyed by heat and by over-discharging.

Installing. Don’t mix battery types, and don’t mix used batteries with new ones. Why? Multiple batteries work as a unit when they all share the same discharge characteristics (current and voltage curves, internal resistance). Just like with musicians, weak or mismatched batteries can degrade the performance of the ensemble. That one sour violin can ruin the symphony, and one bad cell can make you think all the cells are bad.

Recharging (if applicable). Recharge fully each time, preferably right before use. Why? Most rechargeable batteries lose a significant amount of their energy during the first day of storage. There is no reason to partially charge batteries unless you’re really short on time.

Avoid extreme cold. Most batteries have diminished capacity at low temperatures — some losing most of their capacity just below freezing. When using in cold environments, store batteries inside clothing to keep them warm until just before use.

Long term storage of most batteries is best in a refrigerator (not in the freezer, and definitely not in contact with food!). I recommend sealing the batteries inside a vapor-proof enclosure (Ziplock bag will work) to avoid drying the electrolyte in some types, and to protect your food and beer from any accidental chemical leaks (e.g., due to unseen battery case damage).

Wearing Out
. The service life of a rechargeable battery is normally given in terms of the number of full charge/discharge cycles: the capacity declines somewhat initially, levels out, then after many cycles the capacity drops suddenly toward zero (won’t take a charge). But even in storage a rechargeable will age — rather quickly in poor conditions, and in any conditions for LiIon type (details follow) — and will fail after fewer cycles.

Disposal. Batteries can contain various toxic or hazardous chemicals like lead, cadmium, and lithium. DO NOT discard them in regular waste for landfill or incineration. Most communities provide free disposal for batteries.

Bargain Batteries? Some nikon d3100 battery are very expensive. You can find Low prices for batteries on the Internet (such as socanpower.ca). However, some testing has shown that SOME aftermarket replacement batteries do not perform as well as the brand name batteries… even if the cells originate from the same manufacturer. Allegedly the battery houses sell off their rejects (under-capacity, failed temperature range, etc.) to discounters, and those may end up in the aftermarket replacement packs. If buying these, seek a money-back guarantee, and do your own performance assessment (e.g., will they take a good charge) as soon as your receive your batteries.
