THIS SYSTEM BOARD HAS A BIOS LOCK. THIS DOES NOT AFFECT FUNCTIONALITY, BUT YOU CANNOT CHANGE ANY BIOS SETTINGS 
(BIOS IS LOCKED TO THE DEFAULT SETTINGS, WHICH WILL WORK FINE FOR RUNNING WINDOWS 10 OR WINDOWS 11).  

Pulled from a brand new machine with less than 1 hour usage time. Brand new machine was only booted once to confirm parts are 100% functional.


Lenovo ThinkPad X1 Yoga Gen6 System Board.

Also fits Thinkpad X1 Carbon Gen 9. However, due to the BIOS being locked, IF installed into a X1 Carbon Gen9, the Machine will beep at startup due to the X1 Yoga programming. And since the BIOS is locked, you CANNOT reprogram this board to X1 Carbon settings, so you can not remove the beeping. The beeping does not affect functionality, and you can boot past the beeping and it will work fine once in Windows.

(If your board is for a Yoga, it will not beep and you can purchase this board just fine).

Part number 5B21C41883. 
It does not fit any other models.

Pulled from a brand new machine with less than 1 hour usage time. 
Machine was only booted to confirm parts are 100% functional.

Will come with a random serial number preprogrammed in the BIOS, so it won't have any beeping on boot.
Simply install this mother board in your machine and you're good to go.

In stock. Ships from USA.
