3 Remove the memory module, following the instructions
in “Removing a memory module” on page 47.
4 Reinstall the memory module, following the instructions
in “Installing a memory module” on page 44, and making
sure the module is seated properly.
5 Check for the error again.
6 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.
TECHNICAL NOTE: You must have at least one memory module
installed for the computer to work.
Power and the batteries
Your computer receives its power through the AC adapter and
power cable or from the system batteries (battery, optional
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.
