I can't remember the whole thread but it seems you have an nvidia GPU 
and are using nouveau? If so, try installing nvidia-detect and then the 
correct nvidia driver for your system (from elrepo), and see if that 
helps. Could be a nouveau problem.

Hello,

I have received 4 of these machines today, with Nvidia graphics.
I installed all 4 ( first minimal install, then Mate ) and that went ok.
So far they didn't shut down.

greetings, Johan

We also saw some problems with recent Dell machines with ?SpeedStep? or whatever
Intel calls their power/speed management these days.

One developer measured a very significant increase in speed after completely
disabling support for it in his kernel on multiple Linux variants.

I don?t have the details from him, but he said the system went from ?almost
unusable on a daily basis?, to, ?I can actually get things done?.

He mainly uses it as a desktop replacement, so he didn?t care about any benefits
from power management to save battery, etc.

Very ?informal? note? I don?t have the data to turn in bug reports, or time to
chase it down.

He shared what he did informally with a couple of other devs and ?hallway
discussions? have indicated that they also agreed that they had better
performance from the machines.

Sorry, meant to chop the reply off of that previous post after I typed it. 
Argh? accidental top-posting. Icky!

Hello All,

installing these laptops went ok, but indeed, they shutdown on logon.
When coming back up, I get a bios warning about temperature.
On my first attempt on installing Nvidia driver, I wrecked the laptop.
To be continued.

greetings, Johan
