Hi, my all in one screen won’t activate from sleep mode. I’ve tried lots of stuff to no avail. Is there anything new I should know? 
Thanks

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.

Step 3: Check for Windows updates.

Hope this helps! Keep me posted for further assistance.

Thanks Echo_Lake, I have done both of these things but them problem persists, the pc responds to both the keyboard and the mouse and wakes up but the screen won't activate so I am forced to switch off and on at the power switch to get the screen back up.

I appreciate your efforts to try and resolve the issue. I would suggest performing system factory reset will put the computer back to the original factory settings in this way all corrupted and outdated software will be removed. 

While doing the recovery there is an option to backup your personal files. If you have not previously done one now is a good time. 

Restoring Files that were Backed Up Using HP Recovery Manager (Windows )You can also contact HP support for assistance. They can remotely access your system to help alleviate difficulties: www.hp.com/contacthp/

The HP Cloud Recovery Tool allows you to download recovery software to a USB drive. You can use the downloaded recovery image file in order to install the Windows operating system.
