I have a laptop with Windows Vista trying to switch on the LED's light up and starts the fan for a while but then the fan stops and the screen will not turn on or anything but the LEDs are lit. I looked at the screen if the backlight but it's not just this does not turn on. I have removed the hard drive and ram and does exactly the same. I have also removed the processor and heatsink and the same. The LEDs are lit but the screen no nothing. Now I have the motherboard without battery and I'll try again. I await your responses.
