Broken XT2

Hi,

I have an XT2 laptop that isn't working and I was wondering if anyone might know what might be wrong with it. The power adapter has the indicator light on, so the adapter must be fine. The battery light on the laptop works too. But, when I try to start the computer it doesn't start.

I removed the battery and held the power button to discharge any static charge, then put the battery back and tried to start the computer. The light around the power button comes on, but then goes off again after only a second or two. When I close the screen the power light, the one beside the battery light on the lid of the case goes on and when I open the lid again the power light goes off again. The light on the caps lock button is on and the lights above the F4 and F5 buttons are also on, the light above the F4 button was blinking but is now steady.

Could parts of the hardware need re-seating? I've heard that can work.

Thanks for any advice anyone can give.
