thank you for your kind reply.
Unfortunately I am not able to perform the suggested BIOS recovery.
As I stated in my OP, I have no video, keyboard or mouse anymore. On top of that, the HDD doesn't spin up.
So i have no SATA signal, no video signal, no USB signal, meaning an USB stick with a recovery BIOS won't be recognized or initialized nor mounted, either.
I won't bother, this unit is going back as soon as the unit Intel has sent for replacement (my 3rd!!) has arrived.
That's what's great about buying from an Intel certified partner in NL: they send you the new unit and then you have them pick up the defective one. All within 4 or 5 days. Pretty hassle free. So again, with all due respect, I won't bother with the shot in the dark you are suggesting me to try.
I am glad to hear that you are waiting for a replacement.
If you need further assistance let us know.
