System won't wake up from sleep mode even after reboot

[0unce]

Every few days, I encounter an issue where my system will not wake up from sleep mode. I alternate between monitor mode and PC mode regularly. After a few days the HP Envy will not start PC mode when switching from monitor mode. It says PC mode going to sleep and it won;t wake up using the keyboard. It is very frustrating as I have to reboot a number of times and still will not start. I cannot get it back to PC mode

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Step 1: Restart the computer

Restarting your computer erases all information in the computer memory, which might restore functionality.

If the issue persists after restarting the computer, continue to the next step.

Step 2: Enable the keyboard to wake the computer

Enabling your keyboard to wake your computer from sleep mode might resolve the issue.

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.

   

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.

   

5. Click OK.

If the issue persists after setting the keyboard to wake the computer from sleep mode, continue to the next step.

1. In Windows, search for and open Troubleshoot.

   

2. In the Find and fix other problems area, click Power, and then click Run the troubleshooter.

   

   A Detecting Issues window displays while Windows detects and attempts to fix any issues.

   

3. After troubleshooting is complete, close the troubleshooter, or click Explore additional options if needed.

Hope this helps! Keep me posted for further assistance.
