[Ti] Computer "Interference"

Chris -

One other suggestion to add to my earlier response. Depending on the 
settings in your Energy Saver control panel, the CPU clock speed is 
probably running on "Reduced" when you're running on battery  power 
and "Highest" when you plug in the power supply. Try setting it to 
"Reduced" even when you're running from the power supply and see if 
the interference goes away.

P.S. BTW, just to clarify, either I've misinterpreted your original 
post or all the other respondents have - this interference does not 
happen when running from battery, only when you plug the power supply 
in, right ?
