My touchscreen on my A700 does not respond. I used to be able to use the touchscreen to login.
I tried updating the drivers (I believe elo Tyco Electronics TeTouchPlus v 1.4.0 is currently installed). The screen accepts input during calibration, but the touchscreen is still not responding. How do I resolve the issue?
To resolve the issue, please follow these steps:
1. Uninstall the Tyco Touch driver and restart the system
2. Install the keyboard driver
3. Install Tyco Touch driver version 220.127.116.11
