If the UEFI BIOS is corrupted or maliciously attacked, it can self-recover and restore your computer from the last uncorrupted and secure backup. This function protects your computer data.
During the UEFI BIOS self-recovery, the screen might be blank. You can check the progress based on blinking modes of the LED indicators on Esc, F1, and F4. For details, refer to the following table.
Do not press the power button to interrupt the progress. Wait a few minutes until the logo screen is displayed.
| Blinking modes | Self-recovery progress |
|---|---|
| LED indicator on Esc blinks | 0% to 32% |
| LED indicators on Esc and F1 blink simultaneously | 33% to 65% |
| LED indicators on Esc, F1 and F4 blink simultaneously | 66% to 100% |
