ok, i will attempt to test the latest upstream kernel as per instructions. During deb depackaging there were two errors, but it seemed to complete anyway. Here is the text from my terminal just in case:

The only way is to do a hard shutdown. I'm usually in a browser when this happens, and often watching a video or two. It seems to happen more often in Google Chrome than Firefox, but it happens with both. It has happened at least once with no videos loaded. I haven’t observed it freeze / hang when I’m not in a browser, but that's mainly what i use my laptop for, so that's where most of my time is spent. --- ApportVersion: 2.20.1-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: andrew 1949 F.... pulseaudio DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=UUID=e8aaee7c-d956-4519-94f0-cf7aad745020 InstallationDate: Installed on 2015-08-08 (263 days ago) InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) MachineType: Dell Inc.
