LCD BIST
LCD BIST (Built‑In Self Test) helps you determine if a display problem is caused by the LCD or some other part. The test may displays different colors and text on the screen and if you do not notice the problem during the test then the issue lies outside of the LCD.
NOTE: Peripherals may have diagnostics specific to them. For more information, see the documentation shipped along with your peripheral.

NOTE: If you wait too long and the operating system logo appears, continue to wait until you see the Windows desktop, then restart your computer and try again.
