Power Option Plan Settings not working - Display does not turn off

[TAFVA]

My current Power Option Plan Setting in the Control Panel has the screen turn off after 1 hour of inactivity when plugged in. However, the screen does not turn off, even if left alone overnight.

While I am certainly not as proficient as the hard working volunteers who contribute to the community forums, I am average to above average in general knowledge of Windows.
That is, I have customized the Power Options settings in every computer I have owned that operates Windows, so customizing the subject laptop was not new to me.

All my other HP laptops (this is our 4th) turn off the screen after the appropriate duration of time.  This particular device just doesn't perform the actions that I have designated.

I initially brought this issue up in the Microsoft community and performed all the troubleshooting steps they recommended with no change.
Is there another setting that overrides the Control Panel Power Options?

@TAFVA I recommend we start with disabling the hybrid sleep, followed by updating all available Windows updates and the BIOS update from the HP website, please follow the below steps to disable the hybrid sleep after performing a hard reset on the device:

1. In Windows, search for and open Control panel.

2. Make sure the View by setting is set to Category, and then click Hardware and Sound.

3. Click Power Options.

4. Click Change plan settings for the power plan that is selected.

   

5. Click Change advanced power settings.

   

6. Expand Sleep, and then expand Allow hybrid sleep.

7. Select Off from the On battery drop-down menu, and then select Off from the Plugged in drop-down menu.

   
    

8. Click OK.

Greetings.  Sorry, I thought I responded to you over the weekend.  I followed your recommendations, including updating the BIOS and performing a hard reset.

I also checked the Allow hybrid sleep mode and it was already "Off" for both battery and plugged in.

While the computer did go to sleep after making all the changes (I walked away from it for 1.5 hours), it has not gone back to sleep since that time.

As I mentioned, I have set up the sleep mode on 2 other HP Windows 10 laptops, 1 COMPAQ laptap, and other computers successfully...this is the only device that won't go to sleep.

@TAFVA I appreciate the details and I suggest you make a few changes to the way sleep mode works under power options:

Change - "Put the computer to sleep" to preferred time,

And Change - "Turn off the monitor" to never.

Once done, restart the device and check if it works fine.

Keep us posted and have a good day.
