Another thing you could do is you could use your computer “blind” to see if it responds.
- Sleep your computer
- Wake it up
- When the display illuminates, go to
tty2(Alt + Ctrl + F2) - You’d now be at the
gettylogin screen. Type in your username and press Enter. - Type in your password and press Enter.
- You’d now be at a shell. Type
sudo reboot
Give it up to 3 minutes before you hard reset. If your machine reboots, then it’s just the display.
You have to sort of “visualise” what would be on the screen, and mash the delete key or press Ctrl + C if you make any typing errors.
It might be worth giving that a go to see
