Re: Lenovo 490 bios request.
Find it ,make a few backups and compare them make sure theyre the same. Post one of the backups here so we can check if its good or not. Don`t try flashing another bios until then.
At post #1 you said you wanted your bios cleaning, did you mean the ME firmware or a passwordComment

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. 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 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 dear Badcaps-Community,
Somehow an auto update, which I triggered before I left my laptop unattended, bricked my BIOS.
I was able to extract the 2MB BIOS and 16MB BIOS which I will attend. (CH341B black with NeoProgrammer 2.2.0.10)
The Device is a Lenovo Yoga L13 Gen3 and I was able to identify the following specifications:
Lenovo Yoga L13 Gen 3 AMD:
Lenovo Modell: Type 21BB

AMD Ryzen™ 5 PRO 5675U
