Re: C720 Chromebook touchpad stopped working...

I ran into a similar problem with the touchpad on my C720P. The touchpad would stop working during use and would not restore function after powering down and restarting. The touchscreen still worked, but running powerwash, and deleting extensions did nothing. Sometimes after powering off for a long period the touchpad function would return, but would quit again after extended use. This went on for a week.

Finally, I tried reinstalling Chrome OS from a usb drive following these instructions:

When I used "Esc, Refresh, Power" on the keyboard I got a screen saying Chrome OS was damaged or corrupted. This message never occurred when just powering up beforehand.

I went on the reintall Chrome OS from a USB drive. Since then I've run my chromebook for three days without any touchpad problems.
