HP Pavilion 15t - display blurry and blank

[BillVW]

Hi.  I have an HP Pavilion 15t laptop purchased November 2019.  After successfull startup, if I leave laptop idle for a few moments, when I come back to it the display is blurry and the display periodically goes blank.  I have to restart the laptop to eliminate problem.  In a recent start-up, I received an error message about battery performance, but when I run battery diagnostic the results show battery performance is fine. I have not seen the error message a second time.  Thanks for any assistance that you can provide.

The Bios update seems to have solved the problem.  I did not update the graphics (did not fully understand how to do) but doesn't seem to be necessary.  Many thanks for your help getting this problem sorted.  Happy holidays.

Hello @BillVW 

The pleasure is mine !

Kind regards

The problem with a blurry and blanking screen after the laptop is idle has returned.   It was working fine for 3 weeks following our last discussion until a recent automatic update on my HP.  The problem started again. . I went back to our discussion to download and reinstall the Bios as you advised.  However, after 2 days that no longer has solved the problem.  Any suggestions?  Thanks

Thanks Ub6424.   I downloaded. installed the Intel file  you sent and restarted.  Is there something further I need to do with that file?  I wasn't clear about your reply (detect?).  Meanwhile, my laptop display seems to be stable now; haven't yet seen any blurry or screen blanking out.  I will check it later again.  Again thanks, appreciate your fast response.
