I've had this a couple of times since getting my ECLE a few weeks ago.
I didn't have a keyboard handy, so I tried rebooting. It just was a black screen on the 2nd attempt (stayed for over 10 mins before I shut it down). I left it and came back and it booted up normally.
I presume the BIOS settings are resetting, and guess it's due to a failing button battery? Is this a known issue? Thanks!
