Computer "Interference"

[Chris Malanga]

Hey listas,

Got a problem and need some of the electrical/computer experts out there to
help.  I am a mobile DJ and use my TiBook for playing MP3 music (all legal!)
at my gigs.  I also use a wireless microphone.

I have found that whenever the Ti is plugged in, it interferes with my
wireless mic.  I can tell this because the base's "ready" light comes on,
indicating that it has a signal from the mic.  But, the mic's not on.  If I
unplug the Ti, it goes away.  I have tried a number of things including
plugging them into different circuits, replacing my audio cables from the Ti
with shielded ones, etc.   But it appears that the Ti is interfering with
the signal.

Is there anything I can do to isolate the problem?  Any type of cable or
insulator to buy?  Short of unplugging the Ti when I want to use the mic,
that is.  Help would be appreciated.  If you could respond quickly, and Cc:
me as I am on digest, that would be great.   My sister is getting married
this weekend, and I would like to have this problem fixed before then.

TIA...
