Travelmate 4200 touchpad mouse doesn't work.

Shut down, unplug remove battery, plug in, reboot. You can find the user manual here: http://support.acer.com/acerpanam/notebook/0000/Acer/TravelMate4220/TravelMate4220ul.shtml

Reinstall the driver for the touchpad. Try here: http://support.acer.com/product/default.aspx?modelId=774

Plug in a USB mouse and then try to download the Acer driver for your touchpad here: http://support.emachines.com/em/driver/index.html

If you install the newest driver off of the Emachines website, and the touchpad still doesn't work, then it is possible that the touchpad has gone bad.

Unplug everything except the power cord, including the following:

Speakers
Printers
Scanners
USB devices
Personal Digital Assistants (PDAs)
USB flash drive or other external storage devices
External Monitor
External Keyboard
External Mouse
If your computer is attached to a docking station, undock it.



Make sure the touchpad or your finger has no dirt, grease, liquids or food on it (the touchpad has to make a good contact with your finger to work correctly).


Turn the computer back on and retest the touchpad.

When the touchpad still does not work correctly proceed to step 5.

When the touchpad does work correctly, attach one external device at a time and test the touchpad to see which one may have caused the issue.



Make sure the latest driver for the touchpad is installed (you may need to use a external USB or Bluetooth mouse), for more information refer to:
"How to Use the Drivers and Downloads Website"

Hi,

Hold down Fn and hit the F7 key. That will re-enable the touchpad for you.


Regards.

If you have a wired mouse around, you can plug that in, and use it to navigate to the control panel. In Mouse settings, you can re-enable touchpad.
Alternatively, some of the Travelmates have a keyboard shortcut to enable touchpad, Function-F7.
I hope one of these solutions helps!

Hold down the function key (Fn) then press the F7 key. This is keyboard shortcut to toggle on and off the touchpad.

Hold down the function key Fn and tap the F7 key,

now try the touchpad

Uninstall the mouse sofware again and remove the mouse reciever. re install driver and re connect reciever, but in a different usb port if possible, if still not recognised it maybe that the mouse needs pairing to the reciever, so refer to your manual for help on that.
