Windows 10: Why does my HP Envy screen keep randomly going black?

I bought a new HP Envy as my first windows laptop a while ago and had to exchange it for a new one within its warranty because the screen kept going black randomly. If I closed the laptop it would light up again on the log in page and often the keyboard wouldn't be working to put in the password so it would go black again. This would often happen 3/4 times closing and opening it again before it would work again and there was never a clear reason why it would start performing normally again. My second laptop of the same make has been working perfectly for a couple months and now it is doing

HP Envy 20 Black Screen On Startup


On Friday, I updated my HP Envy 20 to Windows 10. Once the update was finished my computer started up fine, however, my antivirus software (AVG) said there was an update and I needed to restart. I did so and after the restart and HP logo screen I had a black, but luminescent screen. After a maybe ten minutes of the screen staying like this, I held the power button down to turn the computer off and then restarted it with no problems. I turned it off Friday night normally and it ran normally all day Saturday. Sunday when I turned the computer on the power light came on and I could hear the fans turn on, but the screen remained black. Just black, not even a luminescent black like when I did the antivirus restart. I tried a hard restart like before but nothing changed. I left the computer on like that for around an hour and nothing changed. Figuring it was maybe a heat issue, I opened up the case and dusted the fan and the heat sink but the problem remains. I posted this problem on the HP support board a few days ago and have heard nothing. Any suggestions on what's next?

 

HP Envy x360 with 1440p screen?

So I bought a refurb HP Envy x360 with the AMD FX 9800P and recently discovered I could set the screen resolution to 2560x1440 despite HP advertising this machine as only being capable of 1920x1080. Has anyone else bought one of these and found they could change the resolution to 1440P? I was thinking maybe since mine is a refurb that it was originally returned for some kind of screen issue and they replaced the screen with whatever they had lying around that day, which could well have been a screen meant for a Spectre, and not an Envy, since the Spectre does come with a 1440p screen. Would a mistake like this even be possible? It came in an Envy box and it says Envy everywhere on the laptop where it should say it. There is no external evidence that this might actually be a Spectre and not an Envy. So is this a fluke or all of these capable of displaying 1440p instead of being limited to 1080p as advertised?

 

My hp laptop screen goes black randomly

Hi afrozahmed1,

Thank you for writing to Microsoft Community Forums.

Could you please help me with the below information:

1. What is the model of HP laptop you are using?
   
2. Does the black screen occur while using the PC or while restarting the machine?
   
3. Are you aware of any changes happened on the computer prior to the issue?
   
4. Which version of Windows you are using? (To check, type:winver in start menu and hit enter.)
   

I appreciate the time you have taken to resolve this issue. There can be many reasons for booting to a black screen.
These screens may appear with or without the mouse pointer.
The main causes are Problems with the driver for your display adapter or incompatible application.

I would suggest you to follow the steps mentioned in the article on
Troubleshoot black screen or blank
screen errors,
refer the section
I see a black or blank screen after signing in to Windows 10.

If that doesn’t help, I would also suggest you to go through the article provided by HP on
Troubleshooting Screen Issues (Windows 10, 8, 7),
refer the section No image on the screen, or the screen is blank.


Disclaimer: The article include the step of updating BIOS. Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems
that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

Hope it helps.
