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 a least one memory 
module installed for the computer to work.

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.

These are some typical problems and recommended 
solutions: 

Make sure the AC adapter and power cable are firmly 
plugged into both a live electrical outlet and the computer.

If the AC power light still does not come on, check that the 
electrical outlet is working properly by plugging in a lamp or 
other appliance.

The battery does not 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.
