[ASK] how to reset BIOS?

[tukull]

i think i may have messed up my bios settings ( disable TPM )

when i choose save and reboot bios, the tablet shut down itself.

but i can feel warm from the back cover, means the tablet itself is powered on but with black screen, no backlight, nothing.

 

i have disassembled the tablet and inspect the PCB, there is no CMOS battery attached.

 

how do i reset bios even there is no CMOS battery present? i can’t even get into DNX mode.
