Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
You're quick to judge I see. Search results are mixed, with one semi-confirmed case and at least 4 that didn't work, hence why I asked about it to get a more definitive idea. I don't have the laptop, I would have tried it otherwise. I'm only supposed to make sure it would be possible on that model for now.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hello! I have problem with Thinkpad P52. I have patched original bios. After flashing it and turning on laptop, it runs maybe 1 minut or so an then plays that "music". And then nothing more. In this thread i found information, that i should clear ME after patching. Done that also, but still same "music" and nothing else. Can someone help?Last edited by SMDFlea; 03-25-2023, 11:57 AM.Comment

What sort of problem,can you explain. Have you tried the Autopatcher at post #1 ,did you press the switch down, have you read any other threads to find out how other members fixed their problems with the t480

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Its not working.
I have 3 thinkpad P52 laptops with password. 2 of them are OK now, but 1 is still with password. I have tryed every bios from this forum, and no result. Wierd thing is that i was patching my original bioses from 3 laptop and non of them was working. Just black screen and that "music". So i was patching one bios dump from this forum and that worked, but only for 2 laptops. So the problem cant be my patching. Programmer also works. I was reading chip, saving dump, flashing it to the chip and reading chip again. Both files are identical. Someone can help?
Maybe someone has another Thinkpad P52 or P72 bios dump, wich is not allready in this forum?
Working patched bios is attatched.Last edited by SMDFlea; 03-25-2023, 11:57 AM.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
I did the processes listed in the post, I get to the part of pressing space twice and turning it off, but when I turn it on again it is looping, falling on the lock screen whenever I restart, what to do now?

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...
