Last night I noticed that my keyboard/docking station was not charging my tablet. When I plugged in the dock/tablet, the charging light came on, but it stayed solid amber. Even though it was plugged in over 12 hours, it never changed to green. The tablet was fully charged when I turned it on this morning, so I know the charger is working. As I used it through the day, though, the tablet steadily discharged even though it was firmly connected to the keyboard/docking station. I don't know whether it's relevant, but I upgraded to ICS earlier this week. It's possible this issue started then and I just didn't notice it until today. Has anyone else seen this? Is it related to ICS, or is it a hardware issue? I appreciate any advice or insight you can offer.
