Keyboard on CB3-131 not properly functioning

DeeTee76

My keyboard on my Chromebook CB3-131 recently stopped functioning properly. Some keys work and some don’t do anything. I tried unplugging the cable and reinstalling it and did a powerwash with no changes. I downloaded the recovery utility onto a thumbdrive and tried to boot into recovery mode, but could not get the laptop to do it holding Esc + Refresh down and tapping on the power, just would restart and go to sign in page. Any suggestions on how to fix the keyboard?

Have you tried plugging a separate USB keyboard in to see if that has the same problem? 

My daughter had a Dell Inspiron laptop (running Windows) that had a similar problem, the fix was to open the back case and remove the keyboard ribbon from the mother board and blow out the connections with some compressed air then put the ribbon back in. You might want to try this if you don't mind voiding any warranty that might still still be extant.

Otherwise I would return the chromebook to the supplier for repair or replacement under warranty if its still covered.

I ended up getting an external keyboard and it works just fine. I will look into the the links you sent sometime soon to see if I can find the fix. Thank you!
