Properties no longer shows battery capacity

I had a problem with not being able to shut off my clip.  When I disconnected it from the USB cable, the display said DICONNECTED and none of the buttons worked.  I could not shut it off - I had to just let it sit all day until the battery totally ran down.  I finally got it to turn on properly and all my MP3s were gone.  

When I charge the clip I usually monitor the battery level by using the Windows explorer display and click on PROPERTIES at which time it used to display the percent charge.  It no longer shows me the battery charge level!!  what can I do to get it back?

I might be wrong, but does it change if you switch USB modes under the Clip’s Settings/USB?

No it doesn’t change
