Touch screen unresponsive

I have an Acer all-in-one touch screen desktop pc. The screen is unresponsive to touch. The Touch Portal opens and I can use the apps but only with a mouse. Calibration is unresponsive. I have returned the computer back to factory default in the hope that a driver or file was missing but it is still unresponsive.

SOURCE: lenovo n500 laptop ... mouse pad not working

The mouse pad maybe faulty or the ribbon cable from the mouse pad to the motherboard may not be properly connected. Reseat this cable.
You can connect an USB optical mouse to the laptop. I prefer you use a USB mouse all the time over the mouse pad.

SOURCE: Acer Aspire One Netbook Touch pad mouse not working

There is a small ribbon cable that connects the touchpad to the motherboard. If there was any dramatic jostling of the system or it was disassembled for any reason it may have come undone. I have heard of this happening in the past.

If your lucky, someone just turned it off. The toggle for the mouse pad is Fn+F7 simultaneously.

Good Luck,

Touch portal

By :"touch portal" I assume you mean either the touch screen. I'm not sure if there is an easy way to do this, but one method which should work is to disable the software used to run the touch screen. One way to do this is to go to device manager, find the touchscreen driver, right mouse button click on it and say "disable." That should turn it off. There are probably other ways, but I don't know of them.

Hi I have an acer aspire Z5700 but the touch portal is not working? You know the little icon in the bottom right corner..when you swipe over it nothing happens? It used to bring up a different screen...

try the recovery partition and make a full recovery of teh system ..That was a parallel function and if it is not there it means something is blocking it ..It maybe nothing but the swiping just not to work ..and this can be fixed by the reinstalling of the drivers..Anyway after engaging the recovery will bring it to the factory condition .., at least it should do ..

Screen touch not working


Clean the touch screen on the phone with an electronics cleaning cloth or wipe. Dirt, dust and oils from your fingertips can collect on the screen, making it unresponsive or desensitized to your finger's touch. Clean the screen in a circular motion.

Eliminate any bubbles under the screen protector. You can do this by removing the screen protector and then reapplying it, going from the top of the screen to the bottom or vice versa.

Remove the screen protector and do not place the protector back on the touch screen. Screen protectors are made for protecting a touch screen, but sometimes the protectors make the touch screen less responsive to your finger touch or even altogether unresponsive.

Power off the touch screen phone if the touch screen stops working when a new program is opened. This isn't a problem with the touch screen, but a problem with the software trying to load or open on the phone. Some programs can slow response time with the touch screen or may not respond to it at all.
