Hi everyone. Long time reader, first time poster. I recently got a refurbished M200. Everything worked fine, but there was a scratchy static sound when turning the volume dial on the front. Now I cannot get any sound. I have reinstalled the sound driver. The volume isn't muted or turned down in windows. The static sound has also stopped. Neither the speaker or headphone jack work. I am quite puzzled. I had the volume dial all the way down when it quit working. My guess is that the dial isn't working. Any advice is greatly appreciated. P.S. Tablets rock! I should have got one a long time ago.
