Hey everyone, first of all thank you all for your help. I have a thinkpad p1 gen2 that i tried using someones previous bios file but now I have a black screen and boot loops. By any chance anyone have a stock bios file? (And/or a patched file? As it previously had a supervisor password)
Thank you!Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hi All!
thank you for sharing this patcher stuff. My success story and some usefull experience follow.
I had a locked Edge E145, TL866 II+ Programmer and SOIC8 ICP clip for it. To obtain a BIOS image I have to desolder Flash Memory's Chip VCC pin - just to disconnect Programmer's VCC from the Mainboard. All other pins were left intact.
I read an original image, patched it using the autopatcher and flashed the patched image back to the mainboard. I have restored Memory's VCC and tried to start the laptop. Saw usual boot messages, request to press <F1> for entering Setup and .... black screen after pressing the F1 key. Many attempts with the same result make me a bit disappointed. Thankfully I have found an another way to the password screen - at the some stage of "normal" booting without pressing F1 the message about "Press Enter to break normal startup" was shown (the message was exact or similar to it) - I did it and become an opportunity to enter Setup from an another Menu. The password screen was here! I entered usual password "123", follow all steps as described in the Readme and, finally, a got message about removing TPM certificate!!!
And now I have two identical E145 - a first one with ruined bottom case part and the second one bought for some coins on ebay as a spare parts donor for the first one. ;-) And both are working now so I not need to carry it from one room to another - there is already a laptop in every room. ;-)
Thanks a lot! And Happy New Year!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...
