How Can I Fix My Disabled Touchscreen?

Below are listed possible causes and solutions for a capacitive touchscreen that is not responding or is not accurate on the Allegro QX.

Device Locked or Touchscreen Disabled

Make sure the touchscreen is not disabled or locked. On rare occasions, the operating system may state that the touchscreen is currently enabled when it is not. Follow the instructions below:

• Press the <Blue> and <Back> arrow key. Repeat as necessary.

• Press and hold Power button until the Power Button window appears, then press the <Down> arrow and <Return> keys to select "Enable TS" or "Disable TS". Repeat as necessary.

Reset the Device

Perform a (Soft or Warm) Reset by pressing and holding the Power (On/Off) button for 5-10 seconds until the screen flashes off briefly and the device resets.

Perform a Hard Reset by pressing and holding the Power (On/Off) button for a full 20 seconds. The screen and LEDs may flash a few times during this time but continue to hold until the full amount of time has elapsed.

Clean Touchscreen

Make sure nothing conductive is adhered to or stuck under the side lip around the touchscreen. After disabling the touchscreen (as explained above) for cleaning the touchscreen and blowing (or washing and drying) out under the side lip, you may need to both re-enable the touchscreen and perform a soft Reset (also explained above).

Switch Touch Profiles

If possible, you can use the hardware keypad or keyboard; an attached USB keyboard or mouse; or a remote display control connection (such as MyMobiler) to navigate to Start > Settings > System > Touch to highlight a different Mode (profile) and select the Load button. If loading another profile resolves the issue, if desired you may be able to switch back to the original profile.
