Allow Touch Device To Wake Computer
How Do I Wake My Computer from Sleep Mode Using a DISPLAX Touch Screen?
If your interactive display is set to go into sleep mode to save power, you likely want users to be able to wake it up simply by touching the glass.
By default, Windows may disable power to USB touch devices during sleep mode. To allow a screen tap to wake up your PC, you must explicitly grant the DISPLAX touch sensor permission through the Windows Device Manager.
Step-by-Step Configuration
Follow these steps to enable the "Wake on Touch" feature in Windows:
Open Device Manager: Right-click on the Windows Start Button and select Device Manager from the menu (or search for it in the Windows search bar).
Locate the Touch Device: In the Device Manager window, find and expand the Human Interface Devices category by clicking the arrow next to it.
Open Properties: Scroll down the list and locate HID-compliant touch screen. Right-click on this entry and select Properties from the context menu.
(Note: If you have multiple touch screens connected, you may see several entries with this name. You can repeat this process for each one).Locating the HID-compliant touch screen properties within the Windows Device Manager.
Navigate to Power Management: In the Properties window that opens, click on the Power Management tab at the top.
Enable Wake Permission: Check the box next to Allow this device to wake the computer.
Save Changes: Click the OK button at the bottom of the window to apply and save your new settings.
Enabling the "Allow this device to wake the computer" setting in the Power Management tab.
Troubleshooting: What if it still doesn't wake the PC?
If you have enabled this setting but touching the screen still does not wake the computer, the issue is likely rooted in your computer's motherboard settings.
Restart your computer and enter the BIOS/UEFI settings. Look for power configuration options such as "Wake on USB" or "USB Standby Power" and ensure they are Enabled. If the motherboard cuts power to the USB ports entirely during sleep, the Windows setting cannot function.
