New issue popped up lately. When my MP goes to sleep the power button stays lit, everything else turns off (external drives, monitor, mouse) and it's completely unresponsive. I held the power button down, it shuts down, but when I press it again it doesn't start up right away. Last time this happened I had to hold press/release/hold press a couple times before it started back up again. I will note I have a USB3 card (the KTXXX 4 port) but even unplugging that didn't seem to stop the random sleep-freeze. Any help appreciated.
