4 Reinstall the memory module, following the instructions
in “Installing a memory module” on page 55, 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 adaptor and
power cord/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 adaptor or power cord/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 adaptor and power cord/cable.
Make sure the AC adaptor and power cord/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.
