From time to time I'll find that I've forgotten to plug in my sleeping C1D Macbook, and the battery has drained so far that I need to plug it in before waking. This is nothing new. But whenever I do this, I find my keyboard won't work unless I do a reboot. And this brings me to my second problem. Any time I do a reboot, I get a "no devices were found that need this firmware update" message, which only started after I tried to update my CD drive a few weeks ago. What's the deal? Thanks.
