Posting in relation to Problem updating BIOS HP Thin Client T640 Automatically - HP Support Community - 8117447

I had the same issue and was able to find a workaround by generating my own template. Someone else may be able to refine it a bit more but essentially for anyone having the same issue:

 

Download the latest BIOS file and replace the one in the template with that from the HP site M43_0121.exe in my case. Remove the final task to delete the files after install (not sure this is 100% this is required)

Then adjust the script to the following:

 

set TMP=C:\TEMP
set TEMP=C:\TEMP
cd C:\TEMP
M43_0121.exe /S

 

The task will run and fail and reboot the device, but it will have actually updated the BIOS as a result. Hope this helps someone save some time.
