Because Ubuntu 15.10 has no wifi driver for xps 13 9350, I install 16.04 beta 1 on it with removing windows. Unfortunately, when use browser to open web site, after a few minutes, mouse stop, then hear the noise of fan become louder, finally system shutdown. When launching the system again, see some error information:Error Code:0711 Validation Code:115480 Service Tag:CGRBM72

The Dell Support Assist site has following description

Failure Description:System detected repeated thermal trips due to excessive heat.

Recommendations:Inspect the system for clogged or obstructed air vents. Make sure that BIOS is current and rerun the diagnostics.

After reinstall Ubuntu 16.04 final beta yesterday, the problem still exists. My bios is newest 1.2.3. Do not know how to find out the real reason.

Read the failure description, your laptop is overheating.

You can install the lm-sensors package to monitor the temperature of your system.

The best way to do this is with the watch command, for live updates. For example:

$ watch -n 1 sensors

I change to ArchLinux and use xfce(its' lighter and will not cause too much cpu loading). Now using browser to read wiki will not cause laptop dead. I guess the Linux driver does not support XPS13 9350 well because the laptop is too new, it needs time. But with xfce, the temperature is not too high like before. This way gives me time to wait, a better kernel or better ubuntu version.
