Black screen on startup, after a few minutes everything is normal

[SaltyMislav]

Hello, 

Sorry for bothering you all, but I have a question.

When I first boot up my PC, for the day, I do not have an image on my display, I can see that the display is powered on because it lights up and keyboard lights up as well. Then after a few minutes when I think that the PC has booted up windows and got to the lock screen I enter my password and my external monitor lights up and shows the image, while the laptop display still remains without an image.

Then a few minutes later, the display shows the image and after that, everything is fine.

The issue mentioned before happens on the first boot only or if I am not using my PC for let's say an hour.

I was wondering if this is something I can fix at home or is it something I have to take to a service shop.

Since this is happening on first boot and after sitting for a bit it sounds like 2 different problems,

1) First Boot, bad video driver or video driver conflict. I suggest going into Device Manager and seeing how many video drivers are listed. If only one, use the proper link via HP or the video chipset company and download the latest video driver.

2) I posted this for another who was having similar issues.

It sound like the system is going into SLEEP MODE and not reactivating the video driver. A Microsoft issue going back to ME.

So try this

1)  Settings>System>Power & Sleep Set Sleep to NEVER

then

2) Click Windows and All Programs Scroll to Windows System Folder> Command Prompt Right Click >More>Run As Admin

then when the black Command prompt window opens put this in there.

powercfg -h off

It will delete the hidden protected hibernation sleep file.

You can set the power settings to turn off the monitor after so many minutes and other items. However Sleep/hibernation has always been an issue with Windows so best to disable. But if it goes into hibernation and the video driver cant be woke up then you will get that screen. Hope it works.
