T440s: BIOS update not working

2017-09-21, 11:20 AM

Hi,

 

I'm trying to update a T440s, currently on version 2.28. The update just reboots but does not perform the update steps. After preparing an USB stick with FreeDOS and using the lcreflsh.bat I got an error code which suggests to disable the security chip. Afterwards the Windows Flash program updates the embedded controller at reboot but not the BIOS. Using the DOS flasher I got this message:

Checking for files and environment ... Done. 
Start flashing ... 
Error during flash. Error code = 19712 ( 81 )

Does somebody know what this error code means?

Hey there,

 

I have exactly the same problem on my T440. It stucks on BIOS 2.33

 

I tried a lot of BIOS versions via the windows utility AND the most recent version due flash with bootable CD. 

 

Is there any solution?

 

best regards

I stopped trying to fix it and I upgraded to and XPS 13 last year anyway. I don't there is fix for this issue, and Lenovo seems to be ignoring bios problems even on newer models
