Notebook doesn't go into sleep mode and doesn't react anymore

HP notebook - 15-ac146nd (ENERGY STAR)
Microsoft Windows 10 (64-bit)

Lately when I try to put my laptop into sleepmode, it doesn't fully go into sleepmode. You can still hear the fan spin. It won't stop by itself. Turning on the laptop is not possible. The only way out is to press the power button for a couple seconds, till the laptop is off. Very annoying since all progress is lost.

 

This problem doesn't occur every time. Only sometimes. 

 

I figured this topic: https://h30434.www3.hp.com/t5/Notebook-Boot-and-Lockup/Blank-screen-after-sleep-mode/m-p/7194889 might solve the problem but unfortunately it hasn't.

  7. When done, click OK.

  8. Restart the computer.

Check for Windows update

Also, Install updates using HP Support Assistant

If the PC does not wake up from sleep or hibernate mode, try these steps: 

 

Enable the keyboard to wake the computer

  1. In Windows, search for and open the Device Manager.

  2. Click the arrow next to Keyboards, and then double-click the name of your keyboard.

    Keyboards selection in the Device Manager window

  3. Click the Power management tab.

    If the Power Management tab is not available, click the Change Settings button. The same Keyboard Properties window opens with the Power Management tab available.

    If you are prompted for an Administrator password or confirmation, type the password or provide confirmation.

  4. Select the box next to Allow this device to wake the computer.

    Allow this device to wake the computer selection in the Power Management tab

  5. Click OK.

If the issue persists, run Windows power troubleshooter.
