Windows 10: Touch Screen not working? Solved!

I have a Toshiba laptop running Microsoft Windows 10. I’ve recently reinstalled the operating system and noticed that the touch screen stopped working. I searched high and low looking for an answer but didn’t find one that would work.

Microsoft recommends the following but it didn’t help me:

  1. Re-start your PC.
  2. Wipe it off. Use a microfiber cloth if possible.
  3. Search Calibrate the screen for pen or touch input from the task bar and select the top result. Hit the Setup button and follow the prompts.
  4. Search Device manager from the task bar and select the top result. Select Monitors and right click on the name of your monitor. If one of the menu items is enable, choose that.
  5. Repeat process number four above, but this time choose Update driver software from the right-click menu.

It was, however, quite close to what I discovered was thedevicemanager problem.   If I went into Device Manager (Windows Key + X and choose Device Manager) and Disabled/Enabled the HID-compliant touch screen device the touch screen would work for a few minutes and then suddenly stop working again.

After scratching my thinning hair on top of my head, it dawned on me that it was probably power management related.  I looked in the Power Management tab for the device but the option was disabled.

Sodevicemanager2 what to look at next?  All of the Human Interface Devices run as USB devices.

Looking at the Universal Serial Bus Controllers I saw that several of the devicemanager3USB Hubs and such did have the Allow the computer to turn off this device to save power option set.
I unchecked the option and disabled/enabled the HID-compliant touch screen device and Voila! the touch screen worked!  It’s been several hours now and the touch screen is still working fine.
