I have a HP Compaq 6820S that all of a sudden has stopped working :smileysad: It had been on unattended for a few hours, and when I came back to it it had frozen with a black screen (I had to hold the power button to turn it off).
Now, when I power it up, the fan kicks in, the caps lock LED flashes on then off, the wireless and power button LEDs stay lit, and the DVD drive continously clicks - but nothing else (screen remains black /off, no beeps, no BIOS/ POST screen).
I've tried with hard disk and/or memory removed, and with/without the battery inserted - with the same result as above each time.
EDIT: have also left the battery out for 24 hours too.
When on nothing happens (caps lock/num lock keys don't light up when pressed, wireless LED doesn't go off when pressed). I've also tried exporting to an external display, again with no luck.
I suspect the motherboard is dead, and it may be new laptop time, but wanted to check here in advance in case anyone has any other suggestions. Can anyone suggest anything?
