Thanks, unfortunately my laptop overheated again within two hours of turning on even with “Power Saving” enabled, it may have helped a little bit though. For clarification I’m using openSuse 11.4
Just checked my Satellite and there’s nothing in the boot options anymore, yet it works! But definitely, when I first bought my Satellite 300 and installed openSUSE (then probably 11.2), the fan would come on after a short while and never stop again. The boot option I then installed in my Grub menu, and which worked instantly, was “acpi_osi=linux”. How did I find that out? By remembering that I had posted about this in an earlier thread here:
Fan goes crazy and keeps spinning - Page 2
Indeed, the issue comes up repeatedly in the Laptop subforum, you might check out the above and similar threads there, even repost there. But try out the boot option first, it might work for you as it did for me. Why I no longer need it, I have no idea! No need to edit your grub/menu.lst permanently to try it out, just enter the above at the menu screen and hit Enter. Good luck!
EDIT: You don’t say which version of openSUSE you’ve installed. If <11.4, the fact that I don’t need the boot option anymore might just mean that an upgrade to 11.4 solves it for you…
Thanks, I’m trying it now. I’m using acpi_osi=linux as a temporary boot argument at the moment as I can’t seem to open the menu.lst file even as a superuser.
sudo gedit /boot/grub/menu.lst

I think I remember the previous time I had this problem it may have been a boot option that solved the problem as well, but I’ll report back how this goes
The fans used in many of the Toshiba Laptops are of an interesting design that may, in part, explain your problem. I note that you report that your fans are running at full speed at startup, so this may not apply, but check just in case. Note: most Toshibas have two fans. We’ve had a couple of ours crash when we could hear the fans, only to realize that one was running and the other is not.
I’ve even noticed that a couple of our Toshibas start up fine, but, when the power management allows the fans to shut down briefly, they don’t restart when needed. There’s a simple reason, and it’s mechanical. The peculiar design of the fan itself is at fault. The fan assembly consists of a housing, a motor secured to the inside of the housing and a plastic blade assembly. Unlike most fans which have the blades secured to a central motor shaft, these blades are part of a single plastic part that consists of the blades, a central shaft that inserts into the motor assembly and a shroud/skirt that covers the motor but spins with the blades. The problem comes when a little dirt begins to find its way into the assembly. Some of the dirt gets into the interior of the fan and coats the shaft, the outside of the motor and the inside of the shroud. As the fan spins that crud gets transformed into a sticky mess that causes the fan blades to need a great deal more force from the motor to make them spin. The problem is sometimes worse when the machine is hot than when cold, making the negative effect on cooling all the worse.
The ONLY way to solve this is to disassemble the PC and remove and clean the fan blade assembly. No amount of canned air or compressed air will do anything more than clean the heat exchanger (and maybe even force some of that crud further into the fan assembly.)
Taking apart a Toshiba Laptop is a daunting task (see my post here, look for post #23). There are good tutorials on line that’ll give you guidance. Try this one. A couple of tips though.
If you follow a tutorial and the PC still won’t come apart remember to look for the little numbers embossed in the Toshiba’s plastic housings right next to the screw heads. Each of the screws with a number next to it has to come out at some point in the whole tedious process of dis-assembly, even thought the tutorial might have forgotten to mention it. If a screw has no number next to it it probably stays, but not always.
Take the steps in the tutorial in order. Don’t skip ahead and take them out of order!
Don’t rush, take your time, especially when handling the little fine wires and cables.
Once you get the fans out just lift the fan blades out and clean the shaft, shroud and motor housing with a cotton swab soaked in rubbing alcohol. Apply one drop (not more) of good quality oil to the shaft and put it all back together.
Good luck. I’ve solved my problems with two PCs this way so far, and the fellow who taught me (Ry) has cured dozens of Toshibas this way.
Note: nothing said above means I dislike Toshiba. Every brand has its flaws, and this one is minor compared to some other brands.
I have rechecked and my fans are almost silent on start-up, but slowly increase as time goes on until the laptop chassis is hot to the touch and eventually the laptop shuts down. After about 10 minutes I can turn it on again but this time the laptop will have fans full blast. Also (curiously) if I’m using the laptop on battery power and then plug in the charger the fans will immediately spin up. Since I am currently on the first boot of the day and on battery the laptop is behaving itself for the moment. Currently I’m balancing the laptop on top of a dinner plate so the underside vents of the laptop aren’t simply on hard table and have some room to circulate air. I’ve also noticed that one side of the laptop emits noticeably more hot air than the other (the cd drive side).
I am not keen on disassembling my laptop, but it is four years old now and I’ve never cleaned the fans from the inside. Its somewhat irksome that the fans are not easily accessible, and I will have to take apart the whole laptop to get at them :(. I will follow the tutorial and keep your tips in mind, once I’ve got some time. My laptop didn’t overheat in normal use on Windows, but I guess I will have to do this eventually anyway so I may as well address the problem fully. Just need to buy some thermal grease and a superfine screwdriver to get at the screws I couldn’t get at easily before
Thanks for all the detailed replies, I will keep you updated
