I always set that Computrace to permanently disabled to every computer that I own, one day I decided to factory reset the BIOS using the menu and observed a strange behavior while doing so

The laptop powered off, I don't know if it's planning to reboot or just powered itself off, I press pwr a few time and it didn't power on so I hold it to force it to shutdown because I think it was stuck in some weird state.

On power on, the screen is black (backlight shown) for 3 minutes or so then it rebooted and showing "bios recovery progress" or something like that, I didn't remembered it correctly.

Once I entered the BIOS again, I'm surprised that the Computrace menu has available again and set defaults to "disabled", why the "permanently disabled" is even there if it's not permanently? I thought it's going to wipe a partition on flash or something that containing the Computrace exec code... but that apparently not the case, it just "disabled but the user cannot enable again"

Also I feel that the BIOS in my machine are kinda unstable for some reason, when I got it new out of the sealed box for the first time then the same behavior also occured, the "text-based bios menu" is kinda built half-assed and I'm pretty sure they didn't test a lot of it, the BIOS password menu is still graphical which looks inconsistent and the countdown makes the text UI misaligned.

I have heard many good things about thinkpad and this is my first device... I really didn't expect it to be like this, guess it's far from IBM nowadays...
