Hello, I also have the Thinkpad X1 Yoga Gen 7 (Serial Number: PF-41RS91, Type Number: 21CE-S1521A ,Factory ID: JVHFC1) The Serial Number and Type Number are both on the casing as well as on the Mainboard. There is no other board model Number that i could find.
I can't enter the UEFI settings because of Admin password lock. I read the 64Mbyte Winbond Chip (there is only one).
I was unable to find the password patterns within the dump and the autopatcher didn't work either.
Any help to clear the PW from the dump would be grately appreciated.
(I was able to put dell lat. 9430 in factory mode by finding and editing 4Hex Values. However i need an unlocked and patched version as template which i cant find for this Model)
Dump is attached CRC32: 682FEEBD

X1 Yoga 7th gen - MEC1723
no solution for the moment

Oh ...
Really no solution at all ? Any hopes of a solution coming?
I know that shorting the contacts doesn't work on the mec1723..
But isn't there some way to clear only the PW from the dump? Or possibly enter a factory mode (as with dell 12th gen) with some Hex Magic
Could I try to flash a clear default bios, or is that doomed to fail ?
ThanksComment

Hey all, I have a Lenovo X1 Yoga 1st Gen (model - 20FQ) with a locked BIOS. I would like to unlock it.
Currently I have it apart in all its glorious bits looking for the security eeprom that I can't find. Plan was to jump it. Next step I think is to pull the BIOS IC and flash a decryption file to it?? I'm a bit confused on that process.
1. Pull the BIOS IC,
2. Read and save the original locked file
3. Flash the decryption file
4. Install and boot up and remove password from BIOS
5. Remove BIOS IC again
6. Flash Original locked... -

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.... -

I've currently got a Lenovo Yoga Slim 7 14APU8 that is not posting. Its fan spins, the keyboard lights up, and the caps lock doesn't work. It was taken to some shop for cleaning, and then they updated or tried to update the bios. After that, there was no display and no post. I've removed the bios ic from the board and made a bios dump. I need some assistance going forward, as I suspect this is probably just a bad bios issue. I've tried searching for a dump, but no luck; if anyone can throw me a bone, it would be much appreciated!
Attached is the bios dump in the state I received it...
