I have a Treo 755. Each day I leave it charging with a sync cable and I sync once each evening. Today I noticed it not only had stopped charging but the computer does not even show that its connected. I played with the cord and connections all morn with no luck. I have two additional sync cables and none of them work either. So we know its not the sync cable. My guess is something has happened to the phone itself. Any suggestions? The phone is acting normal as ever. Anyone else had this happen? Thanks
