How to Clean a CPU Fan
Failing to clean you TOSHIBA Libretto U100 Series docking station (PA3433U-1DV2) CPU Fan can cause the fan to either slow down or to fail completely. If the fan fails, then the temperatures inside the CPU case will significantly increase, which creates the potential for overheating. The easiest way to clean a CPU fan is to use a can of compressed air
1.Shut down your PC and turn the power off. Remove the power cords from the rear of the tower and disconnect them from their power source.
2.Place the tower on top of an antistatic mat that has been laid on top of a table. You may also wear an antistatic wristband that is connected to an electrical ground, like a metal plumbing fixture. You’ll need to use the antistatic devices because static discharge from the floor or from your body could damage data stored on the computer.
3.Open the back of the computer case according to the directions in your owner’s manual. Some CPU’s will require screwdrivers for removal, while others will have buttons to depress before the back comes off.
4.Position your can of compressed air at least two inches from the surface that you are cleaning.
5.Clean the fan intakes and the exhaust using short puffs of canned air. The intakes are the grid-like structures that filter the air that comes into the TOSHIBA Libretto U100 Series docking station (PA3433U-1DV2) CPU Fan.
6.Spray short puffs of canned air over the fan blades. To loosen clumps of dirt, hold your canned air at multiple angles rather than using long bursts of air. Make sure that you do not touch anything inside of the CPU tower.
7.Set the canned air aside and close the back of your CPU.
8.Clean the exterior of your CPU with a damp cloth that has been dipped in soapy, lukewarm water. Dry the surface with a soft towel.
9.Use a damp cloth to clean your power cords while they are disconnected from a power source. Dry the power cords with a soft towel.
10.Return the power cords to their correct positions and power up your computer.
Tips
1.While you are cleaning the TOSHIBA Libretto U100 Series docking station (PA3433U-1DV2) CPU Fan, clean the motherboard and other areas if needed, utilizing short bursts of canned air.
2.Minimize airborne dust in your computer room by cleaning the room regularly. You may also cover your equipment in order to keep dust out.
Warnings: If your CPU fan is not working, then you should only run your computer for a few minutes at a time to avoid overheating and damaging your stored data
What should you consider when buying a laptop battery?
When choosing ACER AOD25 Laptop 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 ACER AOD25 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.
Capacity
The capacity, or power rating is another important consideration. This is the amount of power that the ACER AOD25 Laptop 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, ACER AOD25 Laptop Battery 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 laptop 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.
How to Replace Your IBM ThinkPad R61 Laptop Keyboard
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 laptop’s 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 IBM ThinkPad R61 Laptop Keyboard
The first step of the replacement process is to obtain the right keyboard for your laptop. Compare prices by checking eBay, Google, and online stores that specialize in replacement hardware, such as LaptopKeyboard.com, Spare Parts Warehouse, and LaptopsKeyboard.com. Make sure that the 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 IBM ThinkPad R61 Laptop 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.
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.
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.
Before pulling the IBM ThinkPad R61 Laptop 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.
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 perfectly working keyboard at a fraction of the cost of having a professional repair service do the work!
The power adapter is usually higher than the original non-original power to okay?
Theoretically . Original power certainly better, but the actual use may not feel the difference. Usually we have a safety device input voltage range , such as a 2.5 mobile hard disk , it is plus or minus 5% requirement 5V , too high or too low, the protection circuit will stop the device work. If the protection circuit is activated, it means that before this, your machine has been close to or exceeded its design can withstand the upper or lower limit , which is the life of the machine are influential . ( Of course , non-original power mentioned here , or good workmanship , poor quality products , do not mention it. )
The more important question may be the books of data security, automatic protection of a sudden stop working for a computer is a terrible thing , especially a lot of friends without the battery . Sometimes inexplicable restart the computer , and this is also relevant .
1.3
For the original power supply , the manufacturers are aware of their power needs much load capacity , calculated from the nominal voltage and current security certainly far more accurate .
However, if the use of non- original equipment adapter , such as general-purpose transformers and the like, these issues can not be taken seriously , this is the user can only try to think of ways to get from the power supply parameters are compatible , but the internal resistance of each adapter is different, nominal voltage tolerance may be different, the nominal output voltage variation range of the current may also vary if you are not careful measurements of the relevant values , certainly , there is a risk
Instructions to buy laptop power adapter
As a family of books , is an important accessory power adapter , power adapter when purchasing everyday , we will always meet original and non-original price difference is more, this time on how to choose? This article will briefly introduce our Things to know when the optional power adapter . In looking for your help .
Tools / materials
Computer power adapter of the same nominal voltage, output current of the power supply voltage adapter can pass the same , the output current is different, can not be used on the same books . The basic principle is that a large nominal current of the power supply can replace a small nominal current of the power supply. Estimated that someone would think so , I feel great nominal current of the power will burn the books , because the current big thing. In fact, much the same voltage current situation depends on the load , Oh, think of junior high school physics know . When the books when the high-load operation , the current bigger, when the books go into standby , the current is smaller, a large nominal current of the power supply has sufficient current margin. Conversely, someone with 56w 72w power supply instead of using them is also no problem , because the power adapter is usually designed to leave a margin , load power must be less than the power supply , so this instead of general use is feasible, but the rest of the power headroom rarely , once you pick up a lot of books peripherals, such as two usb hard drive, then cpu running at full speed , then there is a base, a CD-ROM drive at full speed to read the disk , plus the same time charging the battery, estimated to be dangerous , you should feel free to feel power is not already boiled eggs. So it is best not to use a small electric current instead of high-current power supply .
Laptop battery charge does not go how electricity is going on? acer keyboard,dell keyboard
The battery discharges to 0V, and then shut down the state to charge 12-20 hours if your battery is not completely damaged, it should be able to charge into electricity.
Laptop battery itself has a number of uses (lithium is basically 800 times) and aging factors such restrictions, if it is seriously damaged, then only two ways resembles the:
First, in the case of the use of an external power supply; However, if in the case of an external AC power supply to ensure the best stability, with a total power failure has unplugged the computer itself will certainly damage, voltage instability, always boot off too frequently bad, just the total flash lamp will burn is a reason.
Second, configure a new battery, though not original, and can be properly maintained, then it should also be used for a long time.
Purely personal opinion, because I’m trying to get my laptop battery live longer, so check a lot of things, but it does not guarantee the absolute authority in general should be like this.

CPU in the computer will generate heat during operation how to do
CPU in the computer will generate heat during operation , if not the heat , with the heat accumulation caused by burn CPU. So you need to configure the cpu fan heat fan, fan to speed up air flow through the heat timely dissemination . Cpu fan and heat sensor, when the temperature reaches a set region , by adjusting the fan speed sensor , so that the CPU temperature is maintained at a reasonable range.
How much cpu speed normal ?
Because there is a heat sensor cpu above , at different temperatures so cpu speed it is not the same , the general cpu temperature is normal, the speed at 2000-2500 rpm / min or so, there are a number of high-profile users to play games , so cpu temperature on will increase , which could reach beyond the scope of your cpu above 60 degrees Celsius , the same cpu fan will reach 5000 rpm / min. However, in this case the fan is also considered normal. So the specific values of the fan speed is not an accurate value , it is mainly based on the needs of the environment and the user have a great relationship .
Secondly cpu temperature is also associated with voltage . Why? Because the cpu temperature is the heat with the computer power is to measure the size , power and decided to have a relationship with the size of the voltage , if the computer is too low, the heat is small, but when the computer overclocking when the voltage is too small unknown fault occurs . If the voltage is too high, excessive heat , so that the cpu temperature is too high, it will seriously burned to the cpu phenomenon. So we are very difficult to control the voltage , set high, word within the radiator , set low , CPU word within easy BSOD and other unknown fault . But normal circumstances we do not need to worry about the relationship between temperature and voltage cpu , in normal circumstances, the impact is small.
cpu fan speed is not normal how to do ( Editor’s Choice : cpu fan speed is slow how to solve ) ?
cpu fan speed is not normal, then certainly with the cpu temperature is not off the relationship . When the cpu is too high so , cpu speed will reach a very high speed, so we found the bios set by the cpu speed exceeds a certain value, resulting in cpu speed is not normal. But in general the cpu speed of 5000RPM is normal , if your speed range , then here is a little effect.
