I newly got a T500, and in the midst of a couple of topic is the sound card. There is a quiet but separate "buzz" that happen through a number of (not all) pitches. Listening to noisy and destructive music can go down it out, but with quieter playback it can be very irritating. I presently installed the freshest audio driver starting Lenovo by no advance.The noise is also simply easy to hear in the course of headphones, but I know that this is not the headphones themselves for the reason that they sound very well on other computers and portable music devices.I am prying if somebody else has knowledgeable this problem, or has a plan for a result. It's actually simply reproducible: the windows volume example pitch all the time split ends with a noise. You can have the sense of hearing it best when the volume slider is on two clicks above mute. Just click the little slider button.
