You work for a small city IT department and get a call from a customer who says that, when he came back from lunch today, the LCD display on his new laptop was completely blank. He says he can still hear the laptop fans running but there’s no LCD screen image. You visit his workplace to investigate. What could be causing this problem? (Choose three.)

A. The laptop display has failed.

B. The laptop power features have turned off the display.

C. The laptop has shut down.

D. The laptop is set for external display only.

Solution

A, B, and D. It’s possible that the LCD display itself has failed, but you should investigate other options first. If the power settings have shut down the LCD display, try moving the mouse to bring the screen back up. Also, if the customer has been working at his desk, the laptop may be set for external display only, which would result in the laptop only displaying a screen image on an external monitor but not on the LCD screen.
