As of this morning, my D800 is not starting up. When I press the power-on button, all three keyboard indicator lights come on, and then the CAPS LOCK light flashes 10 times before the machine turns off again. No other signs of the machine starting up are apparent.

I have tried removing each of the memory sticks I have in turn, and a different hard drive (I've been noticing hard disc issues over the last couple of days) but it's made no difference.

Does anyone know what the CAPS LOCK light flashing 10 times means? And any idea how I can resurrect my laptop?

Thanks...
