Why does my screen display only white noise?
I opened my Asus Zenbook laptop the other morning, and the display only shows white noise. I tried all kinds of different keyboard startup combinations, removing the battery etc, but nothing seems to work. The computer only starts up and diplays white noise. When I long press the power button, the fan starts making a loud sound. What could be the problem? Thanks for all the help.
Questa è una buona domanda?

Hi @jalle656,
Connect an external monitor (TV?) to the laptop's HDMI port and check if there is a display OK on the monitor when you turn on the laptop and it has booted into Windows.
Press the F8 key a few times to toggle between showing the laptop screen only, the external display only or both on together.
If there is no display at all on the external monitor , the laptop may not even be passing POST (Power On Self Test). Are any of the lights on the laptop e.g. Caps light or Power light blinking at all?

I added a second display, and the display recognizes that a device has been added - the external display just is black, nothing is shown on it even though I toggle the F8-key. The Caps light and power light work normally. Thanks for your answer!
