Your original bios has some corruption in it. The bios at post #2 has the wrong ME firmware and its corrupt.
Try these bios and use NeoProgrammer or ASProgrammer,both good alternatives to the ch341a software

I was using Asprogrammer to flash these two files but it is giving me the error: Press "Unprotect" and check datasheet"]
Used neoprogrammer to flash it but the laptop still don't show nothing on the display.
Any more advice.
Many thanksComment

One or both of those bios should have worked. If you want further help start a new thread in the main laptop forum - https://www.badcaps.net/forum/forumdisplay.php?f=23 .If you have a multimeter post voltage readings on all large grey coils.Comment

Re: Lenovo X1 Carbon Gen 2 (20A) Bios needed
BIOS 1.4
problem with this version:
After BIOS update can't load from any device (SSD/USB/USB-CD)
But can access to the BIOS

after update in BIOS 3(!!!) "ATA HDD" when select bootable device
When press F12 I see SSD/USB/USB-CD, but can't boot from it.
PS In BIOS tested

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... -
Hi all! I was reading on tutorials how to flash a bios to remove password from a bios, and I ended up reading the EC chip instead of the main bios chip, it only gave me a .bin file of 1,024kb, I learned later that that is the EC chip not the main bios chip (I should have read the tutorials here instead before attempting anything, my bad), I went to flash the original backup, the 1,024kb size file into the same chip and laptop is not powering up anymore. I may have screwed the chip or even the motherboard (Hopefully not), I am trying to see if there is a fix before I discard it. I had a couple... -
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, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).
I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...11-17-2023, 10:56 AM -
Hi everyone,
I'm trying to recover a Fujitsu Lifebook E5513 (most likely 2023 model) that was bricked during a BIOS update. The update was interrupted (probably due to power loss), and now the laptop is stuck in a boot loop showing "PBB rollback" / "SBB rollback" messages.
BIOS access (F2) and Boot Menu (F12) are no longer possible – the system instantly reboots after the rollback messages.
I extracted the official BIOS update package from Fujitsu (contains FJNB2FD.CAP, ~18.7 MB) and tried tools like UEFIExtract, but it seems to only contain...
