screen is dim after sleep since windows 10 upgrade

[thomnel53]

Hi.

Ever since i upgraded to Win 10 whenever I log off and the computer goes into sleep the screen is dim when I wake it up. It's fine after I restart it buy it does it everytime. I have checked for driver updates and can't find any. Any ideas? It's a Pavilion 23 all in one.

I have been having exactly the same problem with my Pavilion 23.

Me too! I've googled around but cannot find a solution. I hope someone can help with this.

@aplgc has found a workaround.  Thank you, aplgc.

"Futher testing has given me a reasonable work-around until a new display driver can be distributed.

 I have changed the the keyboard sleep button action to HIBERNATE.    {control panel} {power options} {edit plan settings} {change advanced power settings}  under {power buttons and lid}- select Sleep button action & set to Hibernate.

 I have also set the auto sleep timer to a longer time  {1hour). 

 So now when I use the keyboard sleep key,  the computer hibernates instead of sleep.   This requires a power button press to resume, but the screen brightness is normal and all is well.     If  an auto sleep has occured and the screen is dim--a hibernate cycle will restore brightness without rebooting.

 Hope this works for others".

Same exact problem here with Pavilion 23.  No problems before Win 10 upgrade.

I was having this same issue on my HP laptop and fixed it by enabling my Generic PnP Monitor in device manager...

-  Right click windows logo in lower left corner

-  Select Control Panel

-  In Control Panel select Device Manager

-  In Device Manager, look for Monitors section

     -  Mine had Generic PnP Monitor that was disabled with an error

-  I right-clicked that item and selected Enable

-  If yours is already enabled, right click and disable it and then right click again and enable it

Hope this helps

None of these solutions have worked for me and I am really tired of this issue. I would not have upgraded to Windows 10 if I knew I was going to have to deal with this! I can't even get a screensaver to work on my machine. So I am having to turn my PC off and on all the time to avoid screen burn. 

All I used to have to do was put my PC in sleep mode when it was going to be idle, then wiggle the mouse to bring it back to life. Now if I do that it comes back on but the monitor is always dim so I have to reboot to get the normal screen brightness. Super annoying!
