I just bought a brand new Chromebook 14 yesterday to use for school. I downloaded a few apps I needed to use with my school's online learning modules. Within the first 6 hours, the screen began flickering uncontrollably and locked up the screen. I had to hold the power button to get it to shut down. I am dealing with the same issues today. I noticed the system needed an update and it is currently doing so. Will this fix the problem? I've read that many others have had the same issues. Help please.
