HP Pavilion screen won't wake up

[Nomadz]

Brand new PC was set up yesterday, but once it goes in to sleep mode, no display appears on the monitor if you try to wake it.

I have tried the solutions posted here previously - setting power management for mouse and keyboard to activate machine from sleep. After doing this, I immediately put the machine into sleep mode and the fix appeared to work. However, coming back 20 minutes later the same problem persisted. CPU hums when keyboard is used, but no display on monitor.

The only way I can reset is to hold down the on/off button on the CPU to turn it off,  then restart. After restarting, the display is visible on the monitor - until it goes to sleep.

Any help would be appreciated. Thank you

Don’t worry, I assure you I will try my best to get this sorted.

Press ‘Win + I’ shortcut keys to open Windows Settings app.

Click on ‘Update & Security’, then go to the ‘Troubleshoot’ section from the left-side menu.

On your keyboard, press ‘Windows key + R’ and type ‘Powercfg.cpl’ in it.

Hit the ‘Enter’ key to open power options in the control panel.

From the left-hand side, click on ‘Choose what the power buttons do’.

Then, click on the link ‘Change settings that are currently unavailable’.

From the bottom given power button options, uncheck the ‘Turn on fast startup’ option.

Click on ‘Save changes’ button.

If the issue persists, follow the below steps.

Go to the ‘Start’ menu and type ‘Control panel’ then hit the ‘Enter’ key.

From the top-right filter, choose ‘Large icons’ and navigate to the ‘Power Options’,
