I have found that my DELL CPX laptop will cause considerable noise on
audio channels when it PLUGGED into the wall via an AC Adaptor.  If it
runs on batteries it's much much quieter.  

When I perform, I make sure it's just running on batteries.

That may help....?

I discovered recently, much to my chagrin, that while my motu midi
timepeice
was connected to my laptop via USB, WHILE the MTP was OFF (but devices
connected to the MTP via MIDI cables were ON and patched into my mixer),
resulted in my harddrive's activity being audible through my monitors!
:-(  And no, my laptop was not patched into any other equipment by any
other
means (audio or otherswise, except maybe the same wall outlet).  When I
removed the USB cable, the noise stopped immediately, and the noise
through
the monitors precisely coincided with physically audible hard drive
activity.

[Laptop]<--USB-->[MTP(OFF)]<--MIDI-->[audio
gear]--AUDIO-->[Mixer]--AUDIO-->[Monitors] = hard drive activity
noise!!!

Yucky.

Mike
