How did you do it? I did not believe until the last that the bios password would disappear.😮 You are great, thank you very much. 🤗
Can you tell me how to do it, because I have 2 such laptops with a password in bios. Is this your secret?😚

I guess you used no password forever?
if so you need to clean password and erase security chip then put your bios back to original
otherwise it will never ask you for password again.

my version for windows

When I flash the xxx_PATCHED dump, the laptop does not start. I tried to return the original dump, but it didn't start either. I'm doing something wrong.🤔

I immediately booted PATCHED with no password forever, but the laptop takes a long time to boot, more than 20 seconds.

you mix the bios
it's not the same pc? original 2 and 4 .
normal late display if the file does not correspond to the original PC.
If no password forever starts on the other machine, clean the password and the security chip and put back your original

check with lenovo utility
dump eeprom block 6/7 if password is removed



if it starts with another file, it confirms the bad reading

Of course I understand that. I'm doing oryginal4 right now. Downloading W25Q128BV@WSON8_20240721_123730 oryginal4_PATCHED. Now I will show the photo, because nothing works.

Everything worked out for me!😁 Thank you very much, you are a great professional.👍

Is it possible to bypass supervisor password for Thinkpad t14s gen 3 type 21BS (NM-E091)

Mec1723 No solution with bypass

Did anyone have success with ThinkPad T495s / X395?

It's the NM-C181 board, it uses IT8186VG-192 as an EC chip and I used LPC_AD0 on the J601 connector for the short to ground.

Best I could get was bios not asking me for the password (plus complaints about invalid machine UUID), but I still wasn't able to reset the password, since the bios was still in read-only mode.

Did anyone manage to get the timing right for this machine?

Thanks.

Hi everyone. Searching the web for a SVP bypass has lead me to this forum where I see Maxpower3 is doing excellent work.
I also have the AMD T14 (Gen 3) with the npcx997 and wanted to give the bypass a go. I'm not requesting anything just yet (I will use the info you provided to Arenz earlier in this thread), but just wanted to say hi for now. Best of luck everyone.

[arestlessknight]

My first post was written while I was at work and I did not have access to the T14. The Serial No and Type No are as foillows:
Serial: PF4PM76Y
Type: 21CGS0VT54
Not sure when I will have time to try the bypass, hopefully soon.

Hello friends, first of all, maxpower, I would like to thank you for this work you have done, I have followed the information you have given (Don't save with F10, just clean Pwd with enter twice.) If I do not press f10, nothing changes when I restart, if I press f10, I constantly get an error and it does not save and changes. Nothing is happening, can you help me with this?
