This worked on my Asus TP300L Thanks. Hopefully I won't have to do this everyday.
I had this issue with my VivoBook S400CA touch screen and fixed it today doing the following:
- Go to the Control Panel.
- Go to Troubleshooting (you may have to search for it)
- Click Hardware and Sound
- In the Device section, click Hardware and Devices
- Have the wizard scan your computer for hardware issues.
- Let the computer fix whatever issues you had.
In my case there were 2 USB input devices that were disabled that the wizard enabled for me. The touchscreen immediately started working. Hope this helps someone.
Thankyou this helped me...I didn't realise there was a problem on the USBs too until I did the fix
As a aside note here is what Asus tech support said to do:
For this issue, please follow below steps to enable touchscreen for a try.
- Move mouse to upper right to activate "Charms" and select "Search".
- Type "Device Manager" and open it.
- Click arrow to expand "Human Interface Devices".
note: for me, intermittently, I found a listing for "USB Input Device". You need to be able to see this. Try restarting and returning to
Device Manager until you see this listed. Then, proceed.
- If there, right click "USB Input Device".
- Select "Enable".
- The screen should flash somewhat and then enable your touchscreen.
- Then, right click the same "USB Input Device" and choose Properties.
note: you may now see a long list of enabled devices under the HID listings after enabling the touchscreen.
- Go to "Power Management" menu.
- Uncheck the box marked "Allow computer to disable device to save power." Go to the device manager and opened the "Human Interface Devices"
Under HID- Compliant touch screen I right clicked and scanned for ''hardware changes''. This seemed to reactivate touch screen capabilities.
