Every now and then, your screen may go blank — especially on your laptop. Whether it’s a misbehaving app or a video card glitch, sometimes you just know that your computer is still running but you can’t see anything. Using Fn+F8 to toggle output modes may help, but if not, try this sequence:
- Hit Windows key + R to get the Run dialog box. Even though your screen is blank, Windows will ask you what command you want to execute.
- Type cmd plus Enter to run the Command prompt. (You may know this as the DOS command screen.)
- Press Alt+Enter to toggle full screen mode. This will force your video mode to text mode, which should fix the display problems.
- Type EXIT and enter to close the Command screen. That will return you to Windows mode, and your video should now be restored.
Ideally you’d never need it… but sometimes you just need it!
