Steps to reproduce the problem:
1. Leave Chromebook plugged in overnight
2. Open Chromebook the next day

What is the expected behavior?
It would be nice if my Chromebook could automatically fetch and install updates overnight, like my phone can.

What went wrong?
I get reminded of available updates while I'm in meetings the next day.

Did this work before? No

It's a Chromebook, I don't really care if it reboots as long as it can restore open windows.
