If Something Goes Wrong
Fixing device-related problems
Here are some typical problems and how to solve them:
The AC power light does not come on when you plug
in the AC adapter and power cable.
Make sure the AC adapter and power cable are firmly
plugged into both the wall outlet and the computer.
If the AC power light still does not come on, check that the
wall outlet is working properly by plugging in a lamp or other
appliance.
The AC adapter and power cable work correctly, but
the battery will not charge.
The battery doesn't charge while the computer is
consuming full power. Try turning off the computer.
The main battery may not be inserted correctly in the
computer. Turn off the computer, remove the battery, clean
the contacts with a soft dry cloth (if necessary) and replace
the battery.
The battery may be too hot or too cold to charge properly.
Its temperature needs to be in the range of 50 degrees to 88
degrees Fahrenheit (10 degrees to 30 degrees Celsius). 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 and power
cable connected, wait 20 minutes and see whether 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. Try
replacing it.
