Hello

I'm a newbie here. Need help to remove BIOS admin password of the laptop I just bought. S/N: H7PM6G3-8FC8.
I've been through the posts, and it seems the bios needs to be flashed with some BIN file. Is there a step-by-step guide to make sure it will work?

thanks in advance

I've tried the methods explained in the guide (https://www.badcaps.net/forum/showthread.php?t=103526), but haven't succeeded in removing the password. The removal password generated on https://www.bios-pw.org is not working.


I still need your help...

you must use a spi chip programmer like CH431A , without that you cant create a backup or even flash through the chip on the board.

hello sir thank you help me a lot.

the password in the bios had been removed.

but when I re-installed a new win10 and connected with internet for a while I saw a message shows up.


I have checked online and I thought It due to a option in bios called ‘Absolute'.



I found it can't be changed. Could you help me please?

try. in addition of what you did 1st time, see if you permanently disable Absolute. if not, load setup defaults and you can disable Absolute. Also remove CMOS battery.
