8-4 Troubleshooting
Battery Problems
The battery does not charge (Battery Charge indicator does not light
amber).
Make sure that the AC adapter is properly connected.
Make sure that the battery is not too hot. 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.)
Optical Drive Problems
The CD/Combo/DVD RW 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 CD/Combo/DVD RW drive driver is installed
correctly.
Make sure that the computer supports the disc or the files contained.
