Laptop shuts off after unplugging power cord
Make sure that the computer is receiving power by plugging it into a powered outlet. If it will boot after this, then the battery is suspect. Several problems will cause a battery to malfunction. Sometimes older batteries may not hold a good charge due to age, or the battery might not be recognized by the system. Make sure you leave the computer plugged in for several hours to allow the battery enough time to properly charge before presuming it to be dead. If you find your battery needs replacement follow the battery replacement guide.
Optical drive/floppy drive won't read, or optical drive won't open
There can be a number of issues that can cause your optical drive to stop functioning or reading discs. First, be sure the disc is not the problem. Look for scratches and try another disc if necessary. If your drive won't open try to use a paper clip and stick it in the small hole located near the tray opening button this will eject the tray and you can put your disc in. If your drive won't read at all follow the optical drive replacement guide.
Like with the optical drive, if your floppy drive is not reading your disc, be sure the problem lies with the drive - try multiple floppies. If there is still a problem follow the floppy drive replacement guide.
Laptop shuts down without warning
You were working on that file and didn't have time to save it...
This model is particularly prone to overheating, which can be a problem when you're working away and it crashes on you. Because of the age of this computer, this overheating can be caused by constant, strenuous use or possibly even a buildup of dust. The buildup of dust in the laptop can block air flow throughout, causing the device to overheat. You can carefully blow compressed air into the fan under the laptop to clear dust from it. Another reason for overheating could be that the fan itself is broken, in which case you would have to replace the fan in the computer. In order to do this, follow the fan replacement guide..
CPU Voltage Overload
The amount of time from when you start up until it crashes is seemingly random
There are some problems with the computer randomly crashing due to the CPU's capacitors overloading, causing a failsafe mechanism to kick in, which shuts off your computer. This can be remedied by replacing the logic board.
Touchpad or Right and Left Click Buttons Not Working

The Key Will Not Move
