Ubuntu and laptop fan

Since Iam using ubuntu as main main OS for my laptop I noticed that my laptop temperatures are quickly raising in several cases, and no fan is actually spinning up. According to lm-sensors the temperature of my CPU is 70C in some cases, and no fan that is working. Untill I reboot, and the fan is started by the bios. At that moment, the fan is spinning on the max(?) RPM, and isnt slowed down by ubuntu.

Looking at google several people are noticing the same problem, and several solutions are at internet, however, none of these solutions are actually working at my toshiba laptop. Hopefully someone fixes this anytime soon, as iam pretty sure my laptop doesnt like it to be 70C with normal usage…

Laptop batteries

After WIN7 destroyed my battery (I know people say windows cant be blamed for this, but I still say its windows. How can it happen that a good working battery in October dies within 3 months? I ofcourse know batteries are getting worse if they get older, but within in from a pretty good battery to a really bad battery is not normal).

After that, I decided just to remove the WIN7 install I had, and to replac it with ubuntu. I already used ubuntu at several other PCs, and untill a few weeks I actually needed windows. But now, I dont actually need windows anymore, so I was able to replace my OS with ubuntu.
However, this didnt solve really my problem with the bad battery. The battery last with windows 20 minutes, and with Ubuntu around 30, so its a bit better, but still not much badly enough. So at that moment I had to decide what to do. I can just replace the laptop, or buy a new battery. A new battery isnt really cheap, its aroundd 100+ euro. However, a new laptop is more expensive, so in this case I decided a new laptop would fit better here. So now finally I have a decent battery again (This time one with 9 cells, instead the 6 cells the old one had.) 😛

Windows 7 and laptop Batteries

since around half october I have  been using WIN7 as my main OS on my laptop. At this moment, my laptop battery was working perfectly. Not as good as when it was brand new, but it was working for around 2-2.5 hours (Depending on what I was doing at that moment ofcourse ;)).

However, since I installed WIN7 its getting worse and worse. Begin Januari I noticed my battery was empty after around 1 hour. Woah, thats fast. 2 weeks ago, it was 45 minutes. Its getting worse and worse. According to WIN7 this was at this moment time to replace my battery. It was causing issues, and it might cause that your PC shutdown unexpected. WTF? Looking at google, it gave me some info, and WIN7 does give this message at the moment when the battery charges for less then 40%. At that moment it was 37%.
Now, 1 week ago, this was at 19%, and I was only able to use my battery for 30 minutes. Today, I was able to use it 20 minutes. I suppose within to weeks its just dead? 😛

Now, this is actually going to cost me some money, a new battery isnt cheap. I suppose I also should kick out WIN7, else my brand new battery will be dead within months as well… Time to install ubuntu I suppose.
