Adjust the power management settings for your touch screen
If the touch screen stops working after waking from sleep, adjust the power management settings so that the touch screen device stays active while the computer is in sleep mode.
This setting changes the way your computer sleeps, and might result in more power consumption during sleep.
- In Windows, search for and open Device Manager.
- Expand the Human Interface Devices heading.
- The touch screen device might be labeled HID-compliant touch screen, or similar. Right-click the touch screen device, and select Properties.
NOTE: The name of the touch screen device might differ.Figure : HID-compliant touch screen Properties
- Under the Power Management tab, uncheck Allow the computer to turn off this device to save power, then click OK.
