Just as an off the wall suggestion: Look for lint stuck in the USB port. Seriously. My 810 wouldn't take a charge or connect via the USB port one day. I thought I had broken it somehow. I decided to look at the port under a magnifying glass and discovered it was full of lint from my pocket.
I removed the battery and started carefully digging out the lint with a wooden toothpick (it's non conductive and relatively soft) while looking through a magnifying glass, and blowing out with some caned air. It took me quite awhile, but I eventually got all the lint out. I tested with a USB cable and it went back to 'clicking' into place.
Put the battery back in, cover back on, powered up, and connected to my laptop via USB and things worked. Including charging!
I went back and did the same thing for the ear phone jack. Whoa!!! Now that thing was COMPLETLY plugged up with pocket lint. I hadn't used ear phones in a long time. It took me longer to dig out all the lint from that jack since it is so much deeper than the USB port. I used an X-Acto knife to make barbs on the toothpick to help dig out that lint.
