At this point turning on my 10v gives me nothing: HDD can be heard, power light is on, external HDD runs. But no Dell start up screen nor anything else on the display
What led up to this: I booted into BIOS, enabled USB legacy support (I wanted to boot from a usb drive), saved and exited. Result seems to be a brick -- but the HDD can be heard to spin.
Tried an external monitor and it shows No Signal, so it is unlikely a screen issue (and the timing would be too much of a coincidence). Also tried removing the main battery for an hour: No joy.
Only idea is to open it all the way up and R&R the BIOS coin battery -- but that is a major chore and not one I want to undertake lightly.
Does anyone have any other thoughts?
