On my acer my touchpad is disabled with Fn+F7.
May differ on yours but look carefully at the F keys.
I have an Acer 5732Z laptop that has never given me trouble until today. I was in the process of updating my GPS when it told me to restart the computer with the GPS still plugged into the USB drive. However, when the windows 7 login screen came on, I was unable and am still unable to get my touchpad or keyboard to work. It's not disable, safe mode/system restore doesn't work and I am past warranty so Acer cannot help. Any tricks I am missing? Any help would be thankful.
