Hi,

Thanks for your quick response.

The two computers do not have the same specs. However, I
would expect that the Thinkpad would also be able to run
this without such a drain on the cpu - it's got to be
something else (at least I think so):

Portable - Thinkpad X40, Pentium M 1200 MHz with one gig of
ram. Win XP Pro.

Desktop: P4, 3.2 with 2 gig of ram

The versions of NOD32 are the same and are configured the
same and both are configured to automatically update.

Disabling wireless did nothing to change the pattern. SAS
still goes from about 12 to 55 to 12 to 47 to 14 to 12 to 55
% etc. etc. CPU usage approximately every 2 or 3 seconds.

Another difference between my desktop and my laptop is in
the firewall: desktop uses an old version of Sygate and the
Thinkpad is using Windows firewall. I tried turning off
Windows firewall and for a minute it looked good, but then
it was right back to these wild fluctuations when nothing is
happening.

To answer your question: I am basing this on two readings:
the first is task manager and the second is a utility called
Process Explorer from Sysinternals - they both show the same
thing.

I can't say I've noticed a slowdown while working with the
machine under usual conditions. However, I sometimes use
speech recognition software: Dragon Naturally Speaking.
This software takes a lot of resources. Under these
circumstances, Dragon was slower and less responsive than usual.

Meanwhile, absolutely no such issues on my desktop......

Any thoughts? Any suggestions as to what I might try?

Thanks.
