I was playing around with one old #bios tablet "insys JP4-QI8E" and turned i disabled the only usb port by mistake :/
After this i have no screen nor i have the charging indicator when a usb is connected.
Tried button combos to reset the bios and no dice (there seems to be very few documentation about this one)
I ventured further, opened it up and after no sign of a CMOS battery i desoldered the battery that powers the device in the hope that it would reset the bios.
Left it disconnected a few days and then i resoldered the battery.
Still no dice :(
I know that it is turned on because the CPU gets hot but rather than that no signs that it is alive at all.
Does anyone has any advice on what i should try afterwards?
Any help would be very appreciated as well as boosts for reach.
