Laptop gets extremely hot!

Hi there.

First, excuse me for my English .

Okai here's the problem I have:
Since I've installed Arch I've noticed that the temperature of my laptop is extremely high. It reaches temps between 70-80 degrees Celsius .
First, I used Windows and it was only 40-50 degrees when running games. I also notice that my laptop's battery only lasts like 1 hour (no matter what I do, either browsing the web or watching movies.) While Windows was lasting 3 to 4 hours when browsing the web. I can't seem to find any power options which let me set my processor speed or something like that.

I have used Ubuntu before and it also lasted 3 to 4 hours , There must be a power option or something.
If anyone knows the problem or needs more information, please leave a message.
Thank you so much!

My specs:

Intel® Core™ i3 CPU M 350 @ 2.27GHz
4GB RAM
AMD 5145 Mobility
500GB HD
64-Bit OS.

Re: Laptop gets extremely hot!

Have you installed pm-utils, laptop-mode-tools, cpufrequtils, and/or powertop?  Check the wiki for more information on how to install/set these up (e.g. here for laptop-mode-tools).  After you install/set things up, you might want to check with powertop to see what's preventing your machine from entering a low power state.  Maybe also just check plain old top to see if any processes are hogging the CPU, just in case.

Re: Laptop gets extremely hot!

Thanks! Will definitely check those apps .
Also, I've typed "cpufreq-info" in the terminal and I got this:

current CPU frequency is 2.27 GHz.
  cpufreq stats: 2.27 GHz:100.00%, 2.13 GHz:0.00%, 2.00 GHz:0.00%, 1.87 GHz:0.00%, 1.73 GHz:0.00%, 1.60 GHz:0.00%, 1.47 GHz:0.00%, 1.33 GHz:0.00%, 1.20 GHz:0.00%, 1.07 GHz:0.00%, 933 MHz:0.00%

EDIT: It's 1 AM atm, going to bed. Will check back tomorrow .

Re: Laptop gets extremely hot!

Yes.  You are running wide open (100% of the time you are at the maximum clock speed)
You really want to get cpufreq running and set a governor such as "ondemand"

Will try to install the ondemand one tomorrow. (Don't know how yet )
Thanks ^_^!

Reason    it says that you are running for cpu at maximum 100% of the time. cpufreq will help with that. 

It happens more often than you would believe

Re: Laptop gets extremely hot!

Okai... I only seem to have performance installed. I'm a complete newbie btw , please forgive me.
But how do I install or configure the ondemand governor? This might be a stupid question, but I just can't seem to get it to work
If I try this command:

modprobe cpufreq_ondemand

I get this:

WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/.

Re: Laptop gets extremely hot!

Well, it is a warning; not an error.  If you do a lsmod | grep cpufreq, does the on demand governor show up?  If it shows up, it should work.

You indicated you are not a native English speaker.  Deprecated means that you are trying to use a method that is no longer recommended.  There is a new way to do things you should use in the future because the old way will go away, eventually.

What it is telling you is that you have a file /etc/modprobe.conf and it is suggesting you should no longer do that, but rather put the configuration information in the modprobe.d directory instead.

Would you post the contents of /etc/modprobe.conf ??
