Today I was trying to make my touchscreen working. When I was trying to enjoy new bios from usb my tablet gived me notification [something like ‘u can’t do this cuz u have blocked this option in bios’].
So I have changed some options in bios [in security I thing than I could change something more than imo not in usb option].
Result of my work:
-tablet is not charging
-0 reaction on power button [tryin every combination with power button]
Sorry for my poor english. I hope so that you understand everything that is needed.
