Satellite 1135-s1554 laptop will not boot up from battery or power supply. The first time the error came up was in Sept. 06, since then it has been operating great. The first signs of trouble was the lcd screen display was garbled and you could correct the lcd display screen by moving it up or down.

Last week the laptop was hibernated and the next morning on boot-up:
1. Lcd display screen flashes on and off with white vertical 1 1/2 white strip on the right side.
2. Lcd display screen then fades out.
3. Power supply and battery are removed, and re-installed.
4. External monitor connected to laptop, rebooted Toshiba Screen came up, the hibernating screen came up then came to:
----------------------------------------------
Two choices:

1. Delete Last Restore
2. Restart Computer

Restarted Computer, computer was restarted and went to the Login Screen.
Login was sucessful.
Windows XP sound was heard while booting up.

Blue screen showed:

*** Hardware Malfunction

Call your hardware vendor for support
NMI: Channel Check / IOCHK

*** The system has halted ***

The laptop wil not boot up with power supply or battery now.
Hard drive is ok, it was checked with a desktop with laptop adapter connection.

Thanks for any input.

Update on original post, Laptop trys to boot-up then stops. LCD display screen black, external monitor shows screen while XP is booting up on battery only. Tested power supply adapter shows correct output voltage at 19.6 and it does charge battery. Troubleshooting is still in progress to solve problem, the next time it does boot to screen that shows last restore, restore option will be tried to see if it will fix the problem.

Motherboard replaced, bad connection to Lcd. Check the connection from Lcd before you replace motherboard. System up running great. Replacing motherboard on this laptop was easy using tutorials online. Be sure use thermal grease on the processor. Hope this helps others with this problem.
