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, optional 
secondary 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.

The battery does not charge while the computer is consuming full 
power. Try turning off the computer.

The 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. See 

The battery may be too hot or too cold to charge properly. If you 
think this is the probable cause, let the battery reach room 
temperature and try again.

If the battery has completely discharged, it will not begin charging 
immediately. Leave the AC adaptor and power cord/cable 
connected, wait 20 minutes and see if the battery is charging.

If the battery light is glowing after 20 minutes, let the computer 
continue charging the battery for at least another 20 minutes before 
you turn on the computer.

If the battery light does not glow after 20 minutes, the battery may 
have reached the end of its useful life. Try replacing it.
