Turning off unit while charging - pink screen

Last night, I forgot I had the player charging up via the AC charger and attempted to turn off the unit when I noticed a pink screen come on but the display went dark before I saw what the info was.  What is the info that comes up when you attempt to turn off the unit when it’s charging?  Any possible damage to the unit?  (It still works fine)

If you attempt to turn off the player while it is hooked up to a wall charger, I believe the pink screen message is “Going Into Stand-By Mode” or something similar. It’s not anything to worry about.
