You’ve powered on a laptop, but the LCD screen isn’t displaying any video. The laptop’s lights are working and you can hear the fan and hard drive running. Which of these options would be appropriate troubleshooting steps?
A) The laptop’s memory may have become unseated. Remove the access panel to the memory and reseat all memory modules.
B) The problem may be a bad LCD panel. Try connecting a known-good monitor to the laptop’s video port and restart the system.
C) The laptop’s power supply may not be providing adequate power for the LCD screen. Check the voltage of the power supply with a multimeter.
D) An operating system update may have caused the LCD display to stop working. Restore the operating system from backup or reload the operating system.
