Rule 1: post serial number. This is a forum rule.
Rule 2: use RC unlocker.

Got it， Thank you for your reply. I can do RC unlocker, but I have a few of laptops are with same password, I worry about to damage the chipor motherboard when I remove chip from mothermboard, one motherboard was broken because I'm not a professonal soldering guy.
If it is possiable to retrive the password from bios file, it would be helpful. Thank you.

That is impossible.

That is impossible.

Thank you so much. I got it. Is it possible to flash a unlocked bios file to same password laptop? so as to save time to unlock it one by one. Thank you.

I'm using a RT809F serial ISP Programmer, I can buy one clip and try it. Thank you

I think RT809F can be used with clamp.

Thank you. do you have a universal BIOS file for HP640G2? so I just flash it without unlock it? Thank you.

I tried a few BIOS from here, the result is as follows:
HP640G2 cleared ME .bin : It works, but there is a red bar on the top when boot, it says Manufacture mode
N76 0145.bin, doesn't work
Ir Factory unlock.bin, it works, but it is very very slow to boot
pssw 640G2 unlock.bin, it doesn't work.

Any suggestions? hoaca388 Thank you.

HP640G2 cleared ME .bin : It works, but there is a red bar on the top when boot, it says Manufacture mode ( Use HP Bios Config Utility to fill in the DMI )
Ir Factory unlock.bin, it works, but it is very very slow to boot (Clean the ME firmware )

Unlock the original bios per machine,one at a time.
