Hello, I have this model and the device is fully working but ' Computrace ' is enabled and locked. I cannot remove it. Can you help?

I tried using the above BIOS/EC BINs and they did not work with my model for some reason.

I have attached the Main BIOS file. Hope to hear from you very very soon.

Kind Regards,
Daemon

Tested with your BIOS - Still Active - Cannot be disabled. Check Attached Image.

Any other solutions?

Try again, if the same problem you need to find out how to program IO MEC

Nope that didn't work either sadly.

Hi,

I want to flash T480s BIOS for model 20L8. I want to delete supervisor password.
Currently I have N22ET56W (1.33) and firmware 11.8.65.3590.
Can you help me? Is it safe to flash and are all data (serial no, etc.) preserved?
Also, after flash, can I safely update the BIOS?

Thank you!
