</I>><i> Your message is awfully short of details. What I'd like to know
</I>><i> is:
</I>><i>
</I>><i> 1. What is your laptop's model and specifications?
</I>><i>
</I>><i>
</I>><i> It is a Toshiba Satellite L745-S4210. Specs from manufacturer's
</I>><i> site:
</I>><i> <A HREF="http://us.toshiba.com/computers/laptops/satellite/l740/l745-s4210/">http://us.toshiba.com/computers/laptops/satellite/l740/l745-s4210/</A>
</I>><i> (I paid $100 less than that price last December at Best Buy)
</I>><i>
</I>I have a Toshiba Tecra, and it runs considerably cooler than my old Acer.
><i>
</I>><i>
</I>><i> 2. Which desktop environment are you using?
</I>><i>
</I>><i>
</I>><i> KDE 4.8.2
</I>><i>
</I>So am I.
><i>
</I>><i>
</I>><i> 3. Which applications are you running?
</I>><i>
</I>><i>
</I>><i> As a general rule: Firefox and Konsole. Occasionally Dolphin,
</I>><i> Dragon Player, Libre Office, Amarok.... nothing exceptionally
</I>><i> heavy.
</I>><i>
</I>I would normally have a heavier load than that.
><i>
</I>><i>
</I>><i> 4. Which graphics driver are you using? Is it the proprietary
</I>><i> driver?
</I>><i>
</I>><i>
</I>><i> From lshw: *-display description: VGA compatible controller

</I>The first thing I'd suggest is going into System Settings > Desktop
Search and turn off all indexing. If that solves your problem then
you can either leave it off, or try closing all other software and
letting the indexing happen overnight or while you are doing something
elsewhere. The initial indexing does take a lot of resources and many
people have found that their computers run hot while it is working.
Usually, once the initial run is complete, it doesn't cause any real
problem.
