If Something Goes Wrong
Keyboard problems
The AC adaptor and power cord/cable work
correctly, but the battery will not charge.
The battery does not charge while the computer is
consuming full power. Try turning off the computer.
The battery may be too hot or too cold to charge properly. 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 adaptor and power
cord/cable connected, wait 20 minutes and see if the battery
is charging.
If the battery light 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 light does not glow after 20 minutes, the battery
may have reached the end of its useful life.
The battery appears not to power the computer for
as long as it usually does.
If you frequently repeat shallow charge and discharge, the
battery meter may become inaccurate. Let the battery
discharge completely, then try charging it again.
Check the power options via your Power Plans (see “Power
Plans” on page 84). Have you added a device that takes its
power from the battery? Is your software using the internal
storage drive more? Is the display power set to turn off
automatically? Was the battery fully charged to begin with?
All these conditions affect how long the charge lasts.
After a period of time, the battery will lose its ability to
perform at maximum capacity and will need to be replaced.
This is normal for all batteries.
For more information on maintaining battery power, see
“Changing the main battery” on page 86.
Keyboard problems
You have connected an external keyboard and the
operating system displays one or more keyboard
error messages.
You may need to update your keyboard driver. Refer to the
documentation that came with the keyboard or to the
keyboard manufacturer's Web site.
