Last night I opened my brand new MBP. I transferred things from my old PB, etc. Then I decided to calibrate the battery, so I left it on overnight to run the battery down, and I left it alone all day today. When I got home tonight the battery was obviously dead. I plugged in the power cord and hit the power button and I saw a weird screen with random swirly colors - it kind of looked like somehting from the visualizer in itunes. Then a br made up of parallel vertical bars (sorry I don't know how to describe this) appeared on the bottom of the screen and got darker I think? from left to right, like something was loading. Then I get the weird swirly screen again, then my desktop picture and everything was normal. So is this just something in the new system that it does when it wakes up? Or should I be concerned?
