Lenovo M70Q motherboard model code GH470 NM-C621
Rev 1.0 IQ4X0AL1 10th generation southbridge SRH14
I backed up this BIOS file from another working device, and now I have the same one, but it keeps triggering and cutting out. It's its own modified BIOS file and it definitely doesn't enter the BIOS screen. Can you fix this BIOS file I sent?
