Hi All,
I have a VAIO PCG-K35 that is causing me problems. I have run out of ideas to try so I am looking for some pointers on what to look for next.
I can boot a memory test program and the laptop will run for hours and not shut off. Next I installed a hard drive and used the VAIO recovery disc to restore Windows XP Home. This process takes about 1 hour and the laptop never shut off. During the Windows restore the laptop will reboot when needed, no problems. The 2nd part of the restore is the applications. At this point I see the Windows boot screen (with the progress bar moving). Then the screen will go blank and the mouse pointer will appear and then the laptop shuts off.
What I have tried:
I have removed and cleaned the heat sink fins. Overheating is not the problem.
Memory tests show no errors.
I swapped the DC power board with known good boards. Same problem, at the same point.
I removed the hard drive, placed it in a PCG-K33 and PCG-K37 laptops and Windows loads fine.
After the applications are restored (in another laptop) I placed the hard drive back in the PCG-K35 laptop. Windows will load and then the laptop shuts off. The time is takes to shut off varies. Sometimes it will shut off during Windows boot. Sometimes it will shut off a few minutes after Windows loads.
Does anyone have any ideas on what I should look for next?
Thank you for any help,
Charles
