Incorrectly connected or faulty memory modules may cause errors 
that seem to be hardware or even software related. It is worthwhile 
checking for these first:

Click Start, and then click the Shut down button in the 
lower-right corner of the Start menu.

The computer shuts down completely.

Remove the memory module, following the instructions in 

.

Reinstall the memory module, following the instructions in 

, and making sure the 

module is seated properly.

Check for the error again.

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.

For this model, Slot A is the bottom slot. Slot B is the top slot. If only 
one memory module is to be installed, it must be installed in Slot A.

Your computer receives its power through the AC adaptor and 
power cord/cable or from the system batteries (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:

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.
