This is an HP zt1000 laptop which will not start up. When you press the power button on the unit it lights up then shut off and will not start-up. Now if you push it again there is no response it is dead but if you take and unplug it then plug it back it will light up then shut off. now this is with the battery removed .

With the battery installed it will light up then shut off as many time as you push the button but will not start. I checked the power through the plug and it is good and the battery is new and good too.

Any clues???

Thanks

my guess is power board is bad inside laptop ( note this could be seperate and it could be integrated into the motherboard ) or possibly a short somewhere...

Hello Umbra1...

According to HP, this is a known BIOS problem. They suggest updating the BIOS to resolve the issue.

I thought about the BIOS but it does not even begin to load up the BIOS it shuts off almost as soon as you release the power button. Does anyone know where I can find a diagram of the motherboard to check out/trace the power board?
