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.

I'm still puzzled why the laptop appears to lockup when attempting to login to the desktop environment when using CentOS, but not Ubuntu 15.04. Any thoughts there?
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.
