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?

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!
