    I have i3 la-6842p that powers itself down rapidly even in bios after less than 1 minute. I have swapped Cpu/Ram fitted new thermal paste changed power supply/bench supply but still the same. Where is the best place to start?. Many thanks.

    Hi anybody have experience with this model Toshiba C660 motherboard LA-6842p. Laptop posts then less than 1 minute fan runs fast then shuts down suddenly. I have tried swapping heatsink/cpu/ram but still the same. the most current drawn is 1A. everything is stripped inc wireless card from motherboard. These are what I have so far PJ1=3.3v PJ4 =1.5v PJ5=5.18v PJ11/13=1.04v PJ3=1.78v PJ9=3.3v PJ8/10=1.05v None of these fluctuate greatly or change just before shut down. Many thanks

    How to post bios ?, system wont allow me only .jpg .png ect?
  14. scobie
    No the header is different also laptop wont switch on now. If I put original file on the laptop switches on by itself even without power button attached so Im suspecting BIOS or KBC. Also original problem stillpersists as in no video external or Led screen Black (no video output)

    Hi I have a unit that switches on by itself but no video output all voltages seem to be present on the coils. I was attempting to flash the bios but the one I downloaded from the Toshiba website when extracted my programmer says its too big for the chip. There only seems to be 1 eeprom on the board that I can see. The unit has AMD BGA Cpu onboard. Any assistance wold be greatly appreciated
  16. scobie
    Thank you but no this is different to mine this uses a Wistron KBC but mine uses a Nuvoton, also cpu n mine is bga not socketed.

    You should have your 3.3v alws volatge on both your poweerbutton and at various pins on the Sio/KBC. Find out which pin on the Sio is the kbc_pwrbtn this voltage should go to 0v when the powerbutton is pressed and this should start thing off. Mesmo sem as tensões de 3.3 e 5v esses sinais aparecem no I/O? acredito que não né...abraço

    Again apologies as a newbie but thank you all for your help.
