Probook 440 G5 - Not sending signal to external monitor

[CabeBedlame]

Hello,

I have recent problems with this notebook. Untill now it was working propperly but few days ago my external monitor just went blank and stopped detecting any signal via cable. 

This notebook have HDMI and VGA port - I tried both of them and also tried different monitor but no luck so far. 

When I open display settings I'm not able to see or identificate any seconday display. 

Allready tried to update Win to lastest update and update notebook with HP support center. No luck so far.

Can you please help me?

Hi
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

AND/OR - Windows Logo key + Ctrl + Shift + B
(This key sequence actually restarts you graphics drive(W10 only).)

AND/OR - If you’re using multiple displays, try projecting video to a different monitor.
Press the Windows Logo key + P, select a display, and then press Enter.
