sandy, check on The laptop suddenly shut down and never came back I believe that you are running into the same problem.Just to try something, make sure that you AC adapter works. You will have to have a multimeter and measure the output on the jack of the adapter. Also, remove the battery, the AC adapter and your memory modules, and wait a few minutes. Then reassemble with just one memory module and you want to try it in different slots, also try the other nodule if you have more than one. You can further try to reset your computer. The directions for this are in the service manual which is available here,

Resetting the Computer

If the computer you are servicing has an unknown password,

follow these steps to clear the password. These steps also

clear CMOS:

1. Prepare the computer for disassembly

2. Remove the real-time clock (RTC) battery (refer to

Section 5.7, “RTC Battery,” for more information).

3. Wait approximately 5 minutes.

4. Replace the RTC battery and reassemble the computer.

5. Connect AC power to the computer. Do not reinsert any

batteries at this time.

6. Turn on the computer.

All passwords and all CMOS settings have been cleared.

Give this a try and see what you come up with, good luck.
