Lenovo X1 Carbon 7th Gen Type 20R1
SN: PF1Y5BBJ
Board: GX490 NM-C661 Rev: 1.0
I have made two dumps of this bios, with the bios chip removed from the board and the hashes match on both dumps, but I cannot find the DMI information in the dumps except for the Windows product key, so I think it is corrupted. I have downloaded two bios updates from the Lenovo support site, but they contain small .PAT file, and 4 subfolders containing .FL1 and .FL2 files, which I don't understand enough to figure out how to use to fix my dump.
The problem with the laptop is that... -
Hello all,
I have a Lenovo Thinkstation P500 that is stuck at post with no display, it happened after I changed the memory timings in bios. I can not clear CMOS using the jumper on the motherboard, also tried re-flashing bios suing a USB stick but it also doesn't work. The only solution that I can think of right now is re-flashing the bios chip using an external programmer but the problem is that I don't have the bios dump of p500 for flashing externally and I don't know the location of bios chip. If someone can provide the bios dump and bios chip location it would be really helpful.... -
Hi everyone,
Iām looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.
The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.
I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip ā and the last 2MB in those files are just FF FF FF....
ā What I need:- A working 2MB BIOS dump
- Matching NM-E471 Rev. 2.0, e.g. JY575

The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.
Troubleshooting Attempts:

Hello! I need help getting a modified BIOS for my system. Since I have an engineering processor, is it possible to add the microcode of this engineering processor to the latest BIOS for this laptop model? I think since the BIOS is old, that's why the Wi-Fi driver is not installed on Win10 and Win11, the sound is not adjusted (error code 10 in the device manager) and the screen brightness. The laptop also has BIOS chips W25Q512NW and W25Q128JV, how can...
