Lenovo Thinkpad T440P - BIOS Dump ? (NM-A131)
Hello to all.
I Have in my hands a Lenovo Thinkpad T440P ,which was locked with SVP. Tried with Auto-patch UEFI DXE Driver, but didn't have any result.
But, now the problem even though it was double-verified when i de-soldered both the BIOS Chips.
The laptop doesn't turn on. It FAN cycles.
But i'm pretty sure it's the BIOS that is the problem ,because minutes ago was working just fine, before the -flash- of the autopatcher, BIOS .
I tried to put the old one back in , but again nothing.
So i am attaching the BIOS files .Attached FilesComment

Re: lenovo t440p bios password
Good day to all. I have t440p. Everything went well with this file. But when I returned my original BIOS file, I got a black screen without beeps when I turned it on. Wrote this file again. I have 2x5 beeps and a black screen. Can anyone patch my original file?

Bios backup on lenovo T440P
Hi guys,
I'm trying to save/dump a T440P bios chip (winbond 25Q32FVS) however i'm not succeeding in reading the chip.
I've use 2 different CH341A SOHIC8 programmer, i've tried the clip provided and also unarity clips to ensure the connection was proper. I've modded one CH341A in 3.3V, same result
Computer and bios batteries are removed however, no way to detect/read the chip using the programmer software. Am i missing something?
The laptop is working perfectly fine but i need to get ride of this supervisor password...
Any help appreciateComment

Re: lenovo t440p bios password
It's HP clips
I tried initially with the black clip provided with the programmer but it was too complicated to fix it properly with my big fingers
It's SOIC8 hereLast edited by Grigan27; 04-19-2023, 08:12 AM.Comment

Re: lenovo t440p bios password
Interesting setup
AFAIC see the chip is nor properly connected to the programmer, hence the problem.

Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.
I have a few questions:- If I would buy this laptop and have

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,... -
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... -
Hi, can someone help me please with the removal of the bios password of this dump.
Someone desoldered the bios chip, tried several "methods" but with no luck, and he gave me the dump to try to search some help.
For now he deleted more things and bios password is gone but laptop doesn't show serial, model etc.
Also, I updated bios to latest version, when he will write the dump again without password, it should be better to put back the old version that was orignally or doesn't matter? Because from what I've read this laptop has 3 bios chips, don't know if has... -

But today it's not accepting my password. I'm %100 sure i'm entering the correct password.
I'm trying to reset my bios without success.
I tried :
-I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...
