Originally posted by rskura I knew I spoke too soon. It appears I still have the problem too. Looks like it's time to send the grip in. Or is it the camera?
Aye, mate, it could be either. The thing to do is send in both along with both batteries.
When I saw the update online I was instantly optimistic and updated my camera right away and put in the second battery. It was all I could do to wait the 20 min before trying to turn it back on. My heart sunk when I flipped the switch and nothing happened. Got it turned on and repeated the experiment - same result.
Good luck getting yours fixed. While the problem is not huge or even all that talked about online, there are a handful of us with the same problem and it has to be due to the same defect. While it may still turn out to be software-addressable, the root of the problem is looking more and more like hardware. Since my experience shows the problem to require two batteries, and since I get perfect operation with only one battery regardless of whether that battery is in the grip or in the body, my guess is the fault is in the camera. But that's just a guess.
