Question Fedora 18 Loud Fan Hot Batterylife Consumption


I'm a new linux user with no knowledge of linux OS. I have completed a dual boot along with win.7 as the primary OS. I have noticed that when running Fedora 18 my laptop consumes a lot of power as the fan turns on immediately and gets really hot. To confirm my doubt I decided to use the laptop on battery life running F18 and the battery lasted less than an hour compare to when using Win.7 which runs for more than 2 hours and completely silent. I have Gnome version 3.6.2 and recently updated the packages which were required to update by the Linux OS thinking it would fix any bugs and still having the same problem.

I thought I had to upgrade my video card driver [while on win.7] but no luck and I tried to do the same while on Linux and the driver update takes too long to complete with 101.6 MB ....

I would appreciate any tips/help I can get in order to fix this problem and have my laptop run quiet as it does when on Win.7.

Please remember I'm a new Fedora Linux user and I would appreciate it if you could be very detailed and specific.

I guess most commands are run through the terminal? Maybe some packages specifically related to my issue?

Thank you!!

http://forums.fedoraforum.org/showthread.php?t=273198

that is a bit old, but might help.

i run fedora 18 on an acer laptop that gave roughly the same life as under win7 before i removed win7.

win7 i got roughly 2-3hrs depending on what i was doing.
fedora 18 (starting with beta mind you and updated again last night) i still get 2-3hrs and sometimes i can get as much as 4hrs.

it all depends on what im doing.

as for the CPU fan, can not say as the acer laptop i have has always had the fan 100% full speed in both win7/F18.

you might want to check and see what other services are running that dont need to be running in Fedora as well as be a bit more specific as to what you are doing in Fedora to eat the battery so fast.

hardware specs would be nice too as if the hardware is to old, then that will be a problem for the new OS. keep in mind win7 is 3.5yrs old while Fedora 18 is weeks old. that means Fedora 18 is much newer and could therefor require higher performance from the hardware. my laptop is an i5 with 6G ram and a built in Intel video that is HDMI 1080p shared 1G ram. F18 runs like a champ on that hardware.

I have had major issues getting F18 to run on my desktop (i7, 32Gram, 2x 560gxt Nvidia SLI cards) the issue with that system is the novuue(sp?) that is the "FOSS Nvidia driver" that does not fully support 3D, nor does it have any support for SLI. getting the Nvidia.sh drivers to run and put out SLI support is not easy so i just gave up on it.

Without having hardware specifications we won't be able to give you a reasonable answer.

Most likely it will be the AMD videocard. Install the AMD drivers for it, that should help.

It is the AMD chipset. I had an HP laptop that would run hot and fan ran full speed all the time with the FOSS Radeon drivers because they could not control it's power management features.

Just we warned: as long as I used them the AMD/ATI drivers would break using certain compositing programs like cairo dock. I don't know if they've fixed that yet.

I tried to install the new driver(over 100 MB) which took forever (almost 2 hours) but at the end of the installation I got an error :

the files you opened has some invalid characters. If you continue editing this file you could corrupt this document

I then get an option to try a different character encoding: current locale (uff-8)
western (ISO-8859-15) ----------> and both didn't work
I also get an option to add or remove.

What else can I do to thix the overheating and never stopping fan?

I found this older solved post but can't understand the last reply which solved the problem. How do I get there, do I just copy/paste on the terminal command line?
I'm extremely sorry if these questions sound silly but this is the first time experiencing linux.

You're opening /etc/default/grub in a text editor. Try nano.

Code:
nano /etc/default/grub
nano shows the commands for saving, etc at the bottom of the screen. Caret followed by a key means Press and hold Control, then press the letter indicated, release both.

Then make the changes suggested in that post.

vi is present on every system, but can be a PITA for new users. Try nano first.

Would you happen to know how to choose from two switchable graphic cards. This may be causing my laptop to run so loud and hot. I guess I'd like to have AMD turned off. I don't play games on my laptop so I have no need for them.

Code:

01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Caicos [Radeon HD 6400M/7400M Series]

Have a look for your video driver in the software installation tool (it will have a name beginning with xorg-X11-drv-) and uninstall it: that should fix it.

You might like to try Fuduntu. It is specifically intended to work well on laptops, especially with respect to power consumption. Since it was forked from fedora, it would not seem too different (except fewer bugs).

will this command uninstall my current driver??

yum remove kmod-catalyst xorg-x11-drv-catalyst xorg-x11-drv-catalyst-libs.i686

or

yum remove akmod-catalyst xorg-x11-drv-catalyst xorg-x11-drv-catalyst-libs.i686


This is the machine I'm struggling with. Samsung Intel core i7-2675QM / 2.2 GHz / 6GB RAM/ 64 bit /Window 7 OS/video card AMD Radeon HD 64900M / Intel HD Graphics Family (3000)

I have tried to install a different platform such as Xubuntu and Ubuntu and it still runs loud and hot. I have switchable graphic cards, could that also be the problem?

when using command:

cat /sys/kernel/debug/vgaswitcheroo/switch

0:IGD:+:Pwr:0000:00:02.0
1IS: :Pwr:0000:01:00.0

I have been struggling trying to fix this problem and it's becoming very agitating, someone help! Please.

also, If I install a 32-bit linux OS, are there any "serious" problems?? I'm running out of ideas....

I'm a bit out of my depth here, as I don't have a video card, but I don't think you should have both kmod-catalyst and amod-catalyst; I think they do the same job in different ways. Try getting rid of all the catalyst things and see if it helps.

A trip to Fedora Forum showed quite a few people having trouble like yours. In some cases it was the video card, in others the kernel.
