Hey guys my first post here, long time lurker. My friends laptop went wrong yesterday - he was using it and it turned itself off. I've been having a look at it and have undone some of it however I'm run out of ideas. So far I have removed hard drive, ram , battery. I have also tried to do a reset by holding power button down. All the leds are on, and the fan spins. Heres what happens; Power laptop up LEDS on, fan spins fan stops (2 seconds) fan starts slightly faster speed then it seems to be 'rebooting' itself, as the fan goes off then goes faster. The air from the fan is warm, so I'm guessing theres something on (cpu, northbridge?) Could anyone here help me out? My mate got it for his birthday and can't really afford to replace it - I've reassured him so far that the hard drive is working so his data is fine. The laptop is a toshiba p_200 Thank you so much, I look forward to your replies.
