Problem: Overheating (Yes. I know this is in a lot of other forums and threads, but so far none of them found have been able to help).
Symptoms: System heats from 50 degrees on start-up to 90+ degrees very rapidly when playing video, using DeVeDe, LibreOffice at the same time as Firefox, or anything that is graphic intensive such as The Powder Toy. When the temperature rises the graphics become jumpy, system slows, and I excrete a solid mixture of sand, clay, and lime onto my chair.
Assumptions: I believe that the CPU is having to directly handle all graphics without aid of the graphics card. I believe that the graphics card is only handling standard output without sharing in the processing load.
$ uname -a
Linux hal 3.4.3-1.fc17.x86_64 #1 SMP Mon Jun 18 19:53:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
(When trying to install ATI software, I updated the kernel).
Fedora 17, 3.4.2-4.fc17.x86-64 (Previous kernel)
Acer Aspire 5251-1805 Laptop, AMD V120 2.2GHz, 3GB DDR3, 250GB HD, ATI Mobility Radeon HD 4250 Graphics.
So far in my quest to eliminate the issue, I Switched from Ubuntu Natty Narwhal 64bit to Fedora 17 64bit because Fedora is supposed to work better with Acer.
I installed lm_sensors, it only detected the k10 module which will not output fan speeds or work with fancontrol.
Tried to find a way to make the pcie force the computer to use the system hardware default for controlling the fan rather than the battery saving features that reduce fan power consumption at the cost of cooling. But I looked in the grub.conf files and could not find the options or grub.d file as described in other forums. (See article: w ww.webupd8.org/2011/06/linux-kernel-power-issue-fix.html).
I concluded that it is most likely the graphics card and not the fan at all; and have been trying to no avail to install the proprietary drivers which, as I have read, should solve the problem by distributing the load on the CPU.
Do any of you think this will this work? - http://wiki.cchtml.com/index.php/Fed...allation_Guide
One of the major issues that I seem to be running into is finding validity and concordance in multiple answers. I have read a lot of posts from other users and they all seem to differ in method and software support source. So far official channels seem to only be issuing the statement: 'We don't have a fix at this time. We don't know when there will be one. We hope that you are enjoying our product. (Don't call us, we'll call you)'.
So I really don't know what is reliable or who to trust with my system without turning it into a brick. (I can't afford to buy a brand new lap-top computer as a few people suggested [Are they the ones that are going to pay for it?]).
The only thing I have been able to work with at this point is severely limiting the usage time and putting ice packs on the computer.
