Re: x1 yoga 4th generation password
hey! I'm trying to repair my x1 yoga gen 4, some component on the keyboard side of the board blew and I'm trying to figure out what it was. I can't find a board view, but if you have any pictures of the other (non-CPU) side of the board that would help me a TON. Thanks!Comment

Hello,
I have a X1 Yoga 2nd Generation with a BIOS password. I read the BIOS chip and patched it with the autopatcher. After I flashed the chip, the laptop is not booting anymore. Even I flash the original BIOS back, it is still not booting.
What can be the reason? I attached the original and patched files. I'll be very thankful if anyone can help.
Best regards... -
Hey guys,
have a laptop here that has a supervisor Password (dump in Attachements).
Before i write the Serial NR.etc i wanted to say that strangely after flashing with 3 different Bios dumps and one from lenovos site
the laptop works but everytime it wants me to type a supervisor password i never set.
I thought the supervisor password is stuck in the ec bios but no it isn't either because after replacing the ec chip from one of another board it still has the supervisor password.
Anyway i wanted to ask what of the two chips is the ec bios because on the left... -
Hi Guys,
I thought I write you a tutorial on how to remove your bios password from your lenovo x390 yoga.
Steps:
1. Get an EC programmer and read the EC firmware.
2. Back up your working EC file !!! (on this modell EC stores all hardware infos and you cannot replace it with others)
3. In your EC firmware file find all of these ranges with a hex editor and replace them with 00:
!!!!!! IMPORTANT THAT YOU ONLY MODIFIED THE SPECIFIED RANGES AND NO MORE.
(I have used HxD Hex editor FREE for this since I found that it is easy to replace ranges)

Hi all, I'm new here, a few words about myself: CS student, interested in hardware stuff too - tinkering my whole life but with practically no experience when it comes to firmware "hacking".
So I have this X380 Yoga with a supervisor password in place and before doing anything stupid I figured I'd rather ask.
I plan on using the tool from this thread: https://www.badcaps.net/forum/troubl...password-remov... -
Good day, everyone!
I'm encountering an issue with my Lenovo X1 Yoga 5th Gen laptop related to the BIOS supervisor password. I'm seeking assistance and guidance from the knowledgeable members of this community in resolving this problem.
I am no expert and cannot perform soldering or unsoldering of the chip from the board. Therefore, I attempted to use an EZP 2023 programmer with a clip to extract the BIOS bin file without removing the BIOS chip from the motherboard. The BIOS chip has the following letters imprinted on it: "Winbond 25Q80DVNIG 2026". I used the...
