Hello.
I am trying to salvage Bios locked Lenovo T480 Type 20L5.
I tried couple of times to follow the guide of reading BIOS with NeoProgrammer, autopatching it with Python script, writing onto chip, following the GUIDE and then rewriting original image with erase and verify on.
Unfortunatly every time I fail to save the PC, after all this I try to boot the PC and it is still locked.
Anyone can help me with it, or guide me where am I making mistake?
I am including my original BIOS image with "patched one"Comment

Can I get a patched biosComment

Hello, trying to remove forgotten supervisor pw from my bios, need to do an OS install, pc boots into windows fine but I don't have the a tools to get dump file from the chip physically. Tried to extract a bin from the .exe (which I also included) I last updated the bios with, but I am not that computer literate and I am just confused now. I did find a bin for my 20EQ motherboard but I don't know if it needs to be specifically obtained from my pc.
PC DETAILS:
LENOVO P50 INTEL Ci7 6820HQ
SERIAL - PC0TNEGH
MBOARD - 20EQS4QM00 SDK0J40697 WIN
CURRENT BIOS VERSION: N1EETA2W (1.75)

Just preparing for when I am able to get access to a programmer. Might take a couple of weeks to get it , my country is not so easy to get deliveries quickly, figured I'd get this part of the process done if possible.Comment

Hi!
I have problem with locked T540p
With original (locked) 4MB file works fine, with the patched nothing just blank screen and power led on.
Tried to read again, repatch, rewrite, no luck.
Patcher completes with error "Looking for volumes to patch... [1/1] NVRAM_EfiSystemNvDataFvGuid (checksum 2609h): Not found... Skipping."
What is that?

Problem solved with 4MB file from post #11 of another thread.
Seems like AutoPatcher is unable to correctly patch the 4MB file and produces the above error, this user manually patched it and works like a charm.
Keep in mind that motherboard needs the LAN & USB daughterboard to be connected in order to power up, otherwise doesn't boot!
Thank you all!Last edited by Andreasbest; 06-09-2025, 09:17 AM.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...
