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.

The blue screen text you saw (NMI: Channel Check / IOCHK) is Windows reacting to a Non‑Maskable Interrupt, which almost always means a hardware fault somewhere on the platform rather than a file or driver issue. Given your symptoms (garbled LCD that changes when you move the lid, external monitor works during boot, ultimate fix involved the LCD connection/motherboard), the display path inside the lid is the prime suspect. (learn.microsoft.com)

For anyone hitting the same error on a Satellite 1135 series, try this isolation flow before swapping boards:

  • If an external VGA monitor is stable, focus on the internal display: power down, remove AC and battery, then reseat the LVDS/display cable at both ends (panel and system board). Inspect the cable where it passes through the hinge for pinches or cracked shielding; secure the connector and cable with fresh tape and proper strain relief. Toshiba’s maintenance guide shows the LVDS connector and the correct remove/replace steps for the Satellite series. (manualslib.com)
  • If the NMI still appears, strip to minimum hardware: one known‑good SODIMM, remove mini‑PCI Wi‑Fi and any PC Cards/USB devices, then retest. Reintroduce parts step‑by‑step to find the offender. Windows raises the same NMI bug check for a wide range of board, memory, or adapter faults, so eliminating variables is key. (learn.microsoft.com)

Notes:

  • A display cable intermittently shorting to ground or losing contact can corrupt bus activity and precipitate NMIs, which aligns with your lid‑movement symptom and final resolution. If reseating fixes it only temporarily, replace the cable or the display assembly.

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.
