1) Since unexpectedly in the last week my laptop started to look like it is about to explode (at least @ Mint) - almost always the fan is in total usage (which is very audible, by the way
), I decided to look if the CPU is being over used too. And in fact is strange because only with Firefox opened I get more than 50% CPU usage (sometimes 60%-70%), and with more 2 or 3 programs opened (Emesene, Deluge & Bluefish) I get almost 100%.
2) So I installed cpu-freq to control the clock rate of the CPU (and cpufreq-utils to control it graphically). I added it to the Mint panel but now when I try to select 600 Mhz in it (my CPU is a Pentium M so the CPU Monitor it has 2 options - 600 and 1700 Mhz) it simply does not stick and the 1700Mhz option continues selected.
So I am asking if somehow anyone knows why it only started fanning this way only a week ago ( what I described in 1) - 'top' says npviewer.bin and Xorg are the most CPU demanding processes - ok, I have a Youtube video opened in Firefox but I think that does not explain what is happening) and how can I make the 600 Mhz option usable in the CPU Monitor I added to Mint bar - described in 2).
I'm only asking this because I'm afraid my laptop is about to 'die' and now I feel somehow embarrassed because my PC is clearly audible in all the classes and everyone looks at me, it sounds like a vacuum cleaner :S Also sometimes it stops charging the battery and I think it must be because all the power is being consumed by the CPU.
Thanks in advance,
