Laptop overheating within 15 minutes
We have recently started using Live knoppix at university. We use a wide range of OS's, including Windows, Mac OS X, serveral Linux distro's including SuSe and knoppix, and Unix. However my laptop is having a disagreement, or rather the CPU, with the Live version of Knoppix. After taking logged readings from my laptop the temperature rises at first at an incredible rate and continues to until it reaches about 90 degrees, were quite simple, Knoppix suddenly realises what's happening and shut's down. the problem is that i therefore can only do 30 minutes work on the OS, before i have to cool my laptop down... I discovered that if i get a fan and blow it at the CPU it doesn't die, but that's impracticle. Therefore i need a way to lower the clock speed of my CPU, so that it doesn't heat up so much, and hopefully won't over heat at all.
my CPU is a AMD 64Bit Althon 3000+. I also have 512Mb of Ram as well as a GeForce 5700FX GFX card, so i know those all meet requirements. I can ru n Suse fine on my laptop (infact i get much more out of the battery than I do Windows, and it doesn't get hot at all), so i must assume that either there is some sort of capatibilty problem in Knoppix, or quite simply, the fact that it runs Live, means that my laptop, quite simply, gives up the game with the constant CD access.
I would appreciate any help on this topic, however please note that my online time is limited and Linux doesn't my modem (well not Knoppix anyway), so I will most likely reply to say i have recieved your feedback and then later that day, or the next day, i will make a response on my progress with it. This is jsut because I will be on Windows the whole time I am online, and therefore can't load knoppix to test something out, and then switch back, as my time left, would be small.
Thank-you for taking your time to read this, and thank-you in advance for any help you can offer.
