Well I sure can't find where to post this. It's not a question it's a solution to a problem that was driving me nuts and I wanted other people to know this.
If your touchpad left button stops working and not for the usual reasons - this is what will make it work again.
1. Unplug power cord if plugged in
2. Remove battery
3. Hold down start button for about 20 seconds
4. Put in battery
5. Reboot
I would actually like the whole world to know this as I have googled countless times and never found a solution that works. I have the Acer Aspire One - not one of the locations listed either.
Hope this helps someone! DonnaB
