Error message at startup
Once in a while I get an error screen at startup, claiming that my bluetooth accessories (mouse/keyboard) are not charged. They are in fact fully charged (once I get things sorted out these accessories work fine, which is how I know that they are fully charged and working). In the past I have plugged in wired accessories and rebooted a few times and eventually I get to a screen saying that I need to select my startup disk and that I might need to restore the OS. Eventually I can get it started, but whenever this happens, I lose at least a half hour of doing restarts. Is there anything that might be causing this mistakenly designated error?
