When starting the laptop, the keyboard lights up for a second and the laptop turns off. The process happens constantly until you get the battery.
Can’t get into bios. Cyclic reloading and nothing else.
I suspect it’s a bios problem.
CH341 programmer, read the firmware from the chip (do at least 2 100% identical dumps and check the structure with UEFIToolNE) and post it. Do you have a link to a stock bios-region or firmware?
Gigabyte provides at least a complete firmware image, but by simply flashing this image you’d loose the machine specific data (MAC, serial…)
Don’t forget to check for spi chip voltage. .
