Error during VGA startup after activating secure boot was detected.
I decided to play some Faceit later and the anti-cheat system required TPM 2.0 and secure boot activation. I followed the instructions in the BIOS—activated TPM 2.0, generated a PK key for secure boot, then turned it on. After restarting, the display disappeared completely, no more signs of activity. I also tried removing the battery and resetting pins, and using the power + reset button combo after the reset sequence, but nothing worked. The machine has an i9 10850K CPU, Gigabyte Z490 gaming GPU, 3070 RAM (4x8GB), and a 32GB SSD.
Connecting via the onboard graphics card resolved the problem, allowing me to restart BIOS after multiple battery resets. However, I still can't run Faceit. Solution: switched boot secure mode from standard to custom and then back to standard, which restored functionality.
