Switching from Ubuntu/Mint.Kindly help resolve few concerns

Hello Friends,

I have always been a lover of redhat/fedora stuff, as matter of fact my first linux installed was a Fedora 4 i think. but due to my machine overhitting and things i didn't understand at that time, I switched to Ubuntu so far I have been using Ubuntu.At work I have Ubuntu 12(04 and 11), now raring and on my laptop I have mint. My office wants me to take a RedHat Certification exam. For that I thought I should start using Fedora on daily basis to get to redhat familly philosophy. Before I embark on this journey again. I would like to know if there is a way to prevent shutdown due to overheating.

My laptops overheats I could feel it on the keyboard and the fan makes heavy noise , I know that but has always been fine with both Ubuntu and Mint. Is there any risk that my laptop would shutdown on me when switched to Fedora 19? If yes how to disable that?

I would also like to find out if there is any application like the ubuntu software center

Please feel free to suggest things you believe I should be aware of and careful of etc...

thanks

You do not want to prevent a shutdown when the machine overheats, unless you explicitly want your hardware to be damaged.
Disabling shutdown on overheating (which by the way is a hardware function that can not be disabled for a good reason) would be to hide the symptoms instead of healing the cause.

Having said that, we can help you to fix the original problem, overheating. But we need more information to do that:
- Which hardware is in that laptop?

Code:

lspci
cat /proc/cpuinfo

- Is power-saving for the CPU working?

Code:

cpufreq-info

- If you have a dediacted videochip, do you have the proprietary drivers installed?
- Have you checked if the cooling system is free from dust?

Overheating could be a kernel and/or video driver problem. With some kernels (3.9, I believe) my desktop would overheat when using the nouveau driver, but was fine with the nvidia driver. With 3.11 kernels, I don't see any overheating when running with the nouveau driver.

The nouveau developers still have problem with power management due to the fact that they have to revers engineer it. Now that Nvidia starts to release documentation to the nouveau developers this will hopefully change as soon as the documentation for powermanagement is available to them.
