Re: HP Probook 640 G2 bios dump

hello. I have 640 g2, and i think the bios is corrupted. I flashed many of these notebook but this time i couldn't do it. I attached the saved img file. I tried many but the fan spinning at max. The cpu has 1v, 3.3v, 5v also ok. If i remove the bios ic the notebook doesnt start automatically. what this can be?
