If Something Goes Wrong
Resolving a hardware conflict
3
Reinstall the memory module, following the instructions
in
and making sure it is seated properly.
4
Check for the error again.
5
If the error recurs, remove the memory module entirely
and check for the error again.
If removing the memory module eliminates the error, the
memory module may be faulty. If the error recurs without
the memory module installed, the error is not caused by
the memory module.
Power and the batteries
Your computer receives its power through the AC adapter and
power cable or from the system batteries (main 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
battery will not charge.
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.
