Onderwerp: Re: CentOS 7 + Dell Latitude E6420 laptop = thermalshutdown
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.

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
