The Compal made Compaq NX7000/7010, X1000, HP ZT3000 experienced a similar defect known as the buzzing.
It was a known power supply issue on the motherboard of two capacitors in close proximity for whatever reason deciding to mate and buzz about it.
When sent into HP they would hot glue the capacitors together to make the buzzing stop. They even posteed a bulletin about it at their site.
More enterprising folks found out (and I used to fix my buzzing ZT3000) that if you disabled the USB saving power feature under USB device settings the buzzing went away.
No one took credit or figured out who would have been so bored in his life that he could stop such buzzing by disabling some wierd computer feature (and must have tried thousands of attempts to find such!
I suspect something similar for you, of two discrete components, probably on the power supply part of your motherboard doing the mating dance do to proximity and interaction (defective design) and buzzing about it.
Maybe a really really really really bored and pathetic owner of a dv1000t can after thousands and thousands of attempts figure out some wierd combination of computer settings to make the buzzing go away for you.
........but hey, that fella who figured out how to stop the buzzing in my
ZT3000 with such a stupid thing (I almost feel I must jump up and down on my left foot while facing east and saying the pledge of allegiance to make certain the buzzing does not come back) did me a favor as mine started buzzing horribly at 13 months, just after warranty was up. It was so loud that while doing P2P at night it would wake me up. All is quiet now!
