If Something Goes Wrong
Resolving a hardware conflict
High-capacity battery, and real-time clock (RTC) battery). Power
problems are interrelated. For example, a faulty AC adapter or
power cable will neither power the computer nor recharge the
batteries.
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
main battery will not charge.
The main 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 main battery, clean the contacts
with a soft dry cloth (if necessary) and replace the main battery.
The main 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 main battery reach room temperature
and try again.
If the main 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 main battery is
charging.
If the main battery light is glowing after 20 minutes, let the
computer continue charging the main battery for at least another
20 minutes before you turn on the computer.
