[SOLVED] No display output on laptop

[bentejas10]

Hi there,

I opened my laptop today to a screen with no display.

The backlight is clearly working normally, and the brightness function buttons work to change the brightness.

I also connected an external monitor and I have picture, but only on duplicating the display. When I extend the display, it just reverts back to duplicate.

Not really sure what the issue is. I'm going to take it apart to see if any cables got loose or something.

No time during the boot process is there anything on the display.

I also tried the turn-off display function key to no avail.

Any suggestions would be greatly appreciated.

Laptop: ASUS Vivobook

EDIT: I remember before I went to sleep last night that it did a windows update. Could the update have any impact?

While you're there, make sure that the power cable is removed, disconnect the battery, then hold down the power button for a few seconds. That tip frequently solves problems like your yours.
