for a few hours, the pc turns off automatically without signal, and when I turn it back on, sometimes 3 + 2 beeps, or the led of the capslock key flashes or it turns off without screen. I don't at all want to put back the old bios which contains an unknown password. what do you think would be the issue?

Not a bios problem. it seems that a assembly issue. Again thanks for your bios file.

Thank you.

It's a bad idea to use clip , can you dump your bios by desoldering and read it with Support SOIC8-SOP8 !

Re: hp 640 g2 password need bios dump

Unfortunately, I don't have the right tools to desolder the chip. I read the BIOS and verified it. If that is something. Problem is that laptop beeps two times long and two times short, with a blank screen, and the fan is going like crazy.

Re: hp 640 g2 need bios dump

So, I have tried the bios from the Macronix chip on the Winbond chip and everything works fine.

I have attached the BIOS for Hp 640 g2 - CPU 6300u with cleared ME region for anyone who needs it.

tried on my machine and it says 'booting in manufacturing program mode'
