Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hi
Is it possible to patch BIOS on Lenovo Thinkpad P53s and P15s?
I have Sofi SP8-B programmer with SOIC SOP8 Test clip cable and SOP WSON SOIC VSOP SPI Flash 8p 1.27mm Probe.
I used these to patch BIOS on most Lenovo laptops like: x240, x250, x260, t440, t450, t460, t470, L13, 13 2nd gen, L380, L390, P50, P51s, P52s
Unfortunately I am not sure if ca can Patch BIOS on P15s, and P53s the same way.
RegardsComment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Use the forum search, read some of the other threads and posts,then you`ll know if other members have managed it succesfully or not.Post #1 does say that up to 8th gen can be patched,although there is a way to patch a very very limited number of other later gen models by model type AFAIK.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
while waiting for an answer, I figured it out myself. The patcher works on X250.
1. you need to clean the ME of the original BIOS
2. make a patch of a clean dump through the patcher
3. We solder and start the laptop, but at startup we must put on the cover or hold the S2 and S3 knobs with our hands, they are located near the card reader, see the boardview.
4. follow the instructions
5.return the original biosComment

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...
