Troubleshooting
Computer problems can be caused by hardware, software, or both. When you encounter any problem, it might be a
typical problem that can easily be solved.
This chapter tells you what actions to take when solving common computer problems. It is divided into three sections:
* Preliminary checklist
* Solving common problems
* Resetting the computer
Preliminary Checklist
Here are helpful hints to follow before you take further actions when you encounter any problem:
* Try to isolate which part of the computer is causing the problem.
* Make sure that you turn on all peripheral devices before turning on the computer.
* If an external device has a problem, make sure that the cable connections are correct and secure.
* Make sure that the configuration information is properly set in the BIOS Setup program.
* Make sure that all the device drivers are correctly installed.
* Make notes of your observations. Are there any messages on the screen? Do any indicators light? Do you hear any
beeps? Detailed descriptions are useful to the service personnel when you need to consult one for assistance.
If any problem persists after you follow the instructions in this chapter, contact an authorized dealer for help.
Battery Problems
The battery does not charge (Battery Charge indicator does not light red).
* Make sure that the AC adapter is properly connected.
* Make sure that the battery is not too hot or cold. Allow time for the battery pack to return to room temperature.
* Make sure that the battery pack is installed correctly.
* Make sure that the battery terminals are clean.
The operating time of a fully charged battery becomes shorter.
* If you often partially recharge and discharge, the battery might not be charged to its full potential. Initialize the battery
to solve the problem. (See “Initializing the Battery Pack” in Chapter 3 for instructions.)
The battery operating time indicated by the battery meter does not match the actual operating time.
* The actual operating time can be different from the estimated time, depending on how you are using the computer.
If the actual operating time is much less than the estimated time, initialize the battery. (See “Initializing the Battery Pack”
in Chapter 3 for instructions.)
DVD Drive Problems
The DVD drive cannot read a disc.
* Make sure that the disc is correctly seated in the tray, with the label facing up.
* Make sure that the disc is not dirty. Clean the disc with a disc cleaning kit, available in most computer stores.
* Make sure that the DVD drive driver is installed correctly.
* Make sure that the computer supports the disc or the files contained.
You cannot eject a disc.
* The disc is not properly seated in the drive. Manually release the disc following the method described next:
1. Turn off the computer.
