Unfortunately I don't have any soldering tools or experience, so if you could give an advice about ISP programming (In-System-Programming/In-Situ-Programming) , it will be super helpful! I teardown a bricked laptop, removed AC power, laptop's power battery, and even a small CMOS battery, and

Re: [flashrom] SOIC8 test clip - cant write to BIOS SPI flash chip

his flash chip supports between 2.7V and 3.6V, 3.3V seems OK and I would probably try taking it to Vcc from "USB to TTL adapter" if the solution with a laptop's AC adapter will not work... AC adapter would also powering EC controller, so what if EC will setup a write protect? Best wishes,
