If it still doesn't work when you hook it up to an external monitor, assuming you did that properly, then it is your motherboard/video card.

If you have a seperate video card, I would replace that first. If you don't have a seperate video card, then you need a new motherboard.

FIRST - I would try hooking it back up to an external monitor, and making sure you switch it over to use the external as the default. otherwise you wont get picture.

Sorry... good luck.

If you never see any text at all on the exterior monitor (make sure you used the blue key to switch to external monitor even though it's supposed to do it automatically) you have lost the video chip.

Remove battery and power lead for 30 seconds, then plug both back and start up again.
If you still have the same problem, please let us know if any lights (power, hard disk activity) show when you try and start the laptop.

If you're still under warranty, you can diagnose one possible problem easily enough. Blank white screen with the LED indicator lights running normally otherwise will almost always mean that the LCD panel is bad. If you don't have an external monitor available, find a friend with one and hook up the laptop to that monitor. Be sure to have the laptop power off when you attach the monitor cable. Press the power up button and then the Fn+F? (whatever F key has a little icon on iyt showing a monitor) combo to switch to an external monitor. If your laptop's Operating System shows up on the monitor, you know for certain it's jus your LCD panel that's bad and you can ask the manufacturer to replace it.
