    Ever since I installed Windows 7 months ago on my T400, I've noticed (when docked, with external speakers) it makes a speaker hiss that is correlated to mouse movement (external wireless mouse), and particularly, scrolling with the mouse wheel. I've heard these sounds on other computers, but I never had the issue on mine until I upgraded to Win 7. I've muted and disabled the microphone, and I've tried rearranging the USB plugs (wireless receiver), but all to no avail. Anyone have a cure for the hiss?
