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

</I>Ages ago I had success running "powertop",
don't know if it is still available though.
