Laptops power supply interfiers with modem?

Archived from groups: microsoft.public.windowsxp.help_and_support (More info?)

My wives laptop doesn't connect to the web very frequently. When not in use
it's power supply remains plugged in so as to save the battery. I have
noticed that if we try to connect to the web with the power supply plugged
in there is a shrieking sound coming from modem & we can't connect. Each
time we connect now we have to unplug before we connect. As idea as to
whets the problem?

Thanks in advance
