Chromebook CP311-3H Why does my touchpad stops working?

Jonomite

I have an Acer Chromebook CP311-3H. Every so often, after using my laptop in tablet mode (i.e., tenting/rotating the screen around), when I return to normal laptop mode, the touchscreen no longer seems to work. I've tried various troubleshooting steps--cleaning it, changing touchpad settings, etc--but the only way to get it to restart is to restart the Chromebook itself, which is somewhat of an interruption.

Is this a hardware issue? Or a driver issue? While I'm glad I can fix the issue by restarting the Chromebook, I'm hoping the underlying issue can be addressed so that it doesn't occur in the first place!

Thank you.

Hi @Jonomite

You can try to do a power wash to check if that makes any difference.

Steps for power wash:

Factory reset your Chromebook

1. Sign out of your Chromebook.
2. Press and hold Ctrl + Alt + Shift + r.
3. Select Restart.
4. In the box that appears, select Powerwash. Continue.
5. Follow the steps that appear and sign in with your Google Account. 

NOTE: Make sure to backup all the data before the power wash.

Hope it will help you in some way.

which version of the ChromeOS is installed? Google has been tweaking things a fair amount lately, so they might have mucked up some of the rotation features.
