Fixing device-related problems

The power cable and AC adapter work correctly, but the
battery won’t charge.
The main battery may not be making a good electrical connection.
Turn off the computer, remove the battery and confirm that its
contacts are clean. If they are dirty, clean the contacts with a soft,
dry cloth and replace the battery.
The battery may be too hot or too cold to charge properly. Its
temperature needs to be in the range 5° to 35° C. If you think this
is the probable cause, let the battery reach room temperature and
try again.
If the battery has completely discharged, it will not begin charging
immediately. Leave the AC adapter connected, wait 20 minutes
and see whether the battery is charging.
If the battery icon is glowing after 20 minutes, let the computer
continue charging the battery for at least another 20 minutes
before you turn on the computer.
If the battery icon doesn’t glow after 20 minutes, the battery may
have reached the end of its useful life. Try replacing it.
The battery appears not to power the computer for as long
as it usually does.
If you frequently recharge a partially charged battery, it may not
charge fully. Let the battery discharge completely, then try
charging it again.
Check the power-saving features in TSETUP (Windows 98
Second Edition) or Power Saver (Windows NT). Have you added
a device, such as a PC Card or memory module, that takes its
power from the battery? Is your software using the hard disk
more? Is the display power set to turn off automatically? Is the
battery fully charged to begin with? All these conditions affect
how long the charge lasts.
