Trying to do some troubleshooting on a friends Sony Vaio.

The device does power on, either on battery or mains, and the FAN on the CPU does spin up after it has been on for 30 secs or so.

That is however as much activity as i get. I can't hear any goings on in the HDD, there are no beeps from the laptop, and nothing appears on screen.

Not knowing the boot sequance it is hard to troubleshoot much further.

Can someone provide some information or possible solution to this?

It may well be a paperweight but wanted to ask...
