Overheating ... working on it


Hi all. I've got a terrific laptop with 64 bit AMD Turon /Nvida combo duel processor. I've got it running Fedora 16 32-bit. I love it of course, however it cuts off, probably due to overheating, when I use any intensive applications such as watching a video or copying an iso to a usb drive (with dd). I am planning to install the Toshset acpi driver to see if it helps me keep the system cooled down, but first I have to learn to compile it into the kernel and that means I have to use an intensive application -- the compiler.

Still in the planning stage, but do you happen to know a simple way to keep the compilation process from being very cpu intense -- how I can slow it down? I'd hate for the system to cut off in the middle.

What if I run the compilation process from inside of a freezer at the grocery store? Just kidding.

You could drop the processor clock to avoid overheating with cpufreq-selector command if you have that in slackware, or something of same sort. Stop non used daemons, remove unused software, the less you have that needs to be processed the better your computer will run and less work the CPU will have.

Regards

Maybe you've already done this and felt it so obvious as not to be worth mentioning, but my first impulse would be to vacuum out the vents and to check for airflow to verify that the fans are working.

If the cooling system is working properly, the CPU should be able to work at max normal load without causing shutdowns.

Its true that a system shouldn't overheat without special mode drivers, but this system does. The vents operate normally. I was able to watch the system temperature rising. It would start low and regularly rise until it turned itself off. I attempted to install some utilities to control the cpu and somehow made the system inoperable. This prompted me to recover the system using its vista recovery partition. The recovery software pitched the fan up to high while it was running, something that the fedora 16 could never do. It would always run a lot lower or not at all. This is, I am to understand, due to the unusual and undocumented driver requirements for this laptop.

Anyway, after I recovered it I allowed vista to go through its updates and the system ran for a week or two on vista using its toshiba driver add ins with no overheating, but it suddenly died. Perhaps I will revive the laptop at some later date, and if I do I'll let you know what killed it. I think it was a power surge, or it could be the CMOS battery. There are indications it could have been either. I've put it away and am currently working with debian squeeze on an old Dell with intel graphics 400 mhz bus, a desktop.

Thanks all for the advice. Like I said, if I get the laptop repaired I'll let you know what was wrong with it, in case it has some bearing on the issue.

Yay. The Toshiba laptop is working again, and I realize now it stopped working due to my mistakes. Long story short, I let the battery run down and then turned the system off the wrong way. It wouldn't accept a charge, but after sitting for a week the battery pack began accepting charge once again. The laptop works again. I've got my debian desktop system almost configured with only a few nagging gnome issues, so I can use it to research this overheating issue and how to compile the kernel, use mod utils and add or subtract daemons. I may even compile a kernel for this machine on that machine. Wouldn't that be cool? Then I will seek the holy grail of pc virtualization on my 64 bit laptop.
