You’ve powered up your laptop, but the built-in LCD display doesn’t show anything. The sounds and lights all appear normal, as if the operating system is starting up normally. Which of these would be the next best troubleshooting task?
A) Plug in an external monitor
B) Open the laptop and check the cabling on the motherboard video connection
C) Charge the batteries overnight
D) Replace the internal LCD display
E) The laptop screen needs to be reset. Power down the laptop, pick up the laptop and shake it for about 30 seconds, and then try powering on again.
The answer: A) Plug in an external monitor
If everything else is working normally, it’s possible that the video display or adapter has failed. If you bypass the internal LCD, you’ll know more about the extent of the issue.
