Have you tried to flash back Original BIOS in order to check that you have a “good” backup?Last edited by AAAC; 08-23-2022, 02:10 PM.Comment

Can you go into Setup/BIOS? Power-on the laptop, press F1 key to go into Setup, when asked for password just press ENTER key, if it lets you get in (in read-only mode) go to Security and check Supervisor Password status.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
I am not able to get in SETUP/BIOS (read-only mode).. as soon as I power it On, the "Bottom cover tamper detected" comes up after the Lenovo logo shows up.. which then prompts for a Fingerprint scan or the Power-On password.
Laptop just shuts down after 3 incorrect attempts on the password prompt.
since the Power-On password is enabled, it would be safe to assume that Supervisor Password is Active or Enabled?Attached FilesComment

@esprugodoys
Most probably it's the Supervisor Password Active, unless you haven't reset CMOS by disconnecting all source of energy and also disconnecting CMOS battery.
So if you Original BIOS is good and safely stored, have you tried to look for a T495 patched BIOS to try? This patched bios is only used for the unlock, after that you will use the Original BIOS.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hello again,
first of all thanks for checking my bios file.
Why Am I not able to patch it myself?
Still the same problem, autopacher works, there is information about new bios file created, but the file doesn't egsist in shown source.
Even I tried to patch someone's bios file updated on this forum - the same problem.
Software here: Wind10, Python 3.10.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
The X260 has a W25Q128FV as SPI Flash which is packaged as WSON8. Although the pins are visible as small bullets, there is no way to produce a dump by using a clamp. If you would have used a TL866II instead of a CH341A the programmer would have told you that there is a contact problem. I was not able to produce a dump even by using pogo pins. With WSON8 there is only one way: desoldering.
Lenovo stopped this stupidity and starting with the X270 they used again SO8 packaging.
For the patched BIOS you can use the binary of an arbitrary X260. But after removing the password you need your original BIOS, so you need a verfied dump. By verified I mean: produce as many dumps until two consecutive dumps are identical (fc /b dump-A.bin dunp-B.bin).
Good luck.Comment

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
Hi everyone,
I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.
I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.
After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.
I have desoldered the bios chip (GigaDevice...
