I also need a way to reset BIOS settings to factory defaults

Thank you, Will.
I’m pretty sure already tried those steps, but I’ll repeat it again to double check, following your instructions. Some tip regarding leds?
At moment, I’m trying the force bios reset by discharging battery until depleted. The procedure is described on How to reset bios? Black screen - #10 by DonKing, even being a different equipment I will give it a try.
My Hi10 Go came with keyboard but I’m not able to enter bios setup cause I don’t see anything, the screen is completely off.
I already tried the HDMI adapter to uHDMI, but had no response on the monitor.

The second part of your instructions must the screen working, so I’m not even close to it.

It’s not necessary to say I’m very upsad also.
