RE: XPS 8500 will not start, orange light on motherboard, will not boot, BIOS inaccessible, black screen

Thanks for your reply to my post.

So the graphics card might be damaged? Any suggestions on how to debug?

I did disconnect (what I think is) the data line from the HD but no change. In what way should it show failure?

I have done the following actions so far to try and resolve the matter:

- Disconnect all externally attached devices except screen and key board

- Disconnect the DVD and HDD from motherboard

- Reset the CMOS by removing the motherboard internal battery for 10min

- replace the motherboard battery

None of these actions has made any differenece
