Windows 10: Laptop display wont turn on sometimes, until I press ctrl+win+shift+b

Since some days ago my laptop screen has been refusing to turn the main display back on after being turned off.


It never turns off abruptly, in other words it always turns off in intended ways, for example when I leave it idle for 30mins or when I plug it to my monitor, or I just shut down the computer in these situations I want the display to turn off .


The problem is when it comes the time for it to turn back on, and this doesnt happen every time, but it just refuses to turn the display back on no matter how many keys i press. For example I'll unplug my main monitor and then the laptop monitor remains black though every key remains responsive, I can clearly tell the computer is still working I can press space to pause/unpause the video I was watching and the sound gives me feedback that everything is working.


I have found a way to salvage this without continuously forcing shutdowns and restarts until it works and that is by pressing CTRL+WIN+SHIFT+B which produces a beeping sound and after pressing it some times it lags and beeps a lot the display finally comes back on.


The icons on my desktop are scrambled when the display recovers from this.


Now, everytime this happens I check the reliability monitor and it declares multiple instances of hardware error, the timestamp points to the moment I tried to turn the display back on, and not to when it turned off. The reliability log gives no relevant info on which piece of hardware is malfunctioning but the log is this:


Description
A problem with your hardware caused Windows to stop working correctly.

I have tried reinstalling my vga drivers to no avail and right now I am considering just to reformat the computer, however I would like to ask if this really looks like an hardware problem or is just some software problem that will be fixed with a full format.


Thanks in advance

Update KB4022716 causing black screen after screen timeout [Four Displaylink USB adapters in system]

On my laptop it works just by pressing the "Ctrl + Shift + Win + B" keys. I don't have to turn off the monitor and press the power button.

 

CTRL+SHIFT+8 and some others not working

Okay thanks. Didn't know that tool.
It does list Ctrl+Shift+, 3 & 8. But it doesn't say what they're registered to. (And nothing seems to happen when I press them.)

The tool turns up a very short list, by the way, compared to the screenshots on that site. Just these three plus:
Hot Key : Alt+Ctrl+Delete
Hot Key : Alt+Ctrl+J (I know what this is from)
Hot Key : Alt+Ctrl+K (Kindle)
Hot Key : Alt+F4

 

Shift/ctrl key problem.

Hi Jovan,

The issue you're experiencing is probably due to incorrect settings. A Windows Ease of Access feature called
Filter keys is an accessibility function that tells the keyboard to ignore repeated strokes. When this function is enabled, it ignores whatever key is pressed down or repeatedly pressed. To verify this, follow the steps below:

• Open Control Panel.
• Click on Ease of Access.
• Under Ease of Access Center, click on Change how your keyboard works.
• Under Make it easier to type, click on Set up Filter keys.
• The Turn on Filter Keys should not be checked, as well as
  Turn on Filter Keys when right SHIFT is pressed for 8 seconds.

We also suggest that you play around with the features and check which one works best for you. If the issue persists, let us know.
