Like "...Provide the full machine model number, serial number (or Service tag, SNID) and the board model number (see https://www.badcaps.net/forum/showthread.php?t=88758 ) ,The serial number, make, full model number, motherboard model and revision (except QR codes) must be written/typed at your request as per the rules.

Hi everyone,

Could someone please help me remove the Supervisor password?
I attempted to use an autopatcher, and now when I try to enter the BIOS I get a black screen.

Good luck

I've seen a few users reporting problems about "cmd closing imediatly after open the autopatcher". For those who are having this trouble, just try an older version of Python. I had the same trouble, but I fix it using the 3.13v. Glad if helps a little

the bios you currently have on your laptop, which you want to unlock..

Yes, it is the original BIOS, but not the same version that the laptop was shipped with. The current BIOS installed on the laptop is the latest one, version 1.80. The laptop was shipped with BIOS version 1.50 tho.

Yes, the laptop has the Lenovo BIOS, but when you say original do you mean a BIOS that has never been updated?

Are you using the original BIOS of your laptop....

I have got a Thinkpad L470 with locked BIOS. I havent done any BIOS unlock before. My question is, do I need a new pristine BIOS image and use it with the script, or is the script used with the dump of the exact same BIOS that you want to unlock?

Hi, just wondering if you could share those pics again? I'm looking to fix my p50. I've already found one chip that could be the bios chip, close to the RAM, at position u5, but I'm not sure if it's the correct chip.

Can't seem to find an Edit button, so I guess I'll go like this.
I just went for it, and it worked out. PW is removed, U5 is indeed the BIOS chip.
Thanks

@Merlinox
I’ve just sent you a PM with links of 2 pictures showing BIOS chip location on ThinkPad P50.

thanks very much,its working

[szepesif]

which programmer and which software

Ch341 ??

if you can't, try EC bypass

https://www.badcaps.net/forum/troubl...-ec-pwd-bypass

I had to try a few times, but I was able to get into the BIOS with this method, and now the P50 board is finally supervisor password free. Thank you for all of your help! I wanted to leave a comment about the success for future visitors.

Revelprog with its original software.

I didn't know there were LPC lines here that I could use to get into the BIOS. I used that method several times in the past. I will give it a try here as well.
