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.
As there are no jumpers in the tablet to reset the BIOS i wonder if it might be possible to just connect some handles of the chip to reset it.
Thing is i have no idea which of these is the bios, i looked up the references
The closest thing might be the 25Q80BVSIG which pops as "8M-BIT SERIAL FLASH MEMORY WITH
DUAL AND QUAD SPI"
Could this be it? i have no idea of what i am doing
