Hi, I got my first Mac last Sunday (woo!) but I was using it last night and a battery warning came up. I had been using the MBP, then turned it off and went out with battery still remaining. When I came back again a few hours later I used the Mac and after about 10 mins closed the lid for some reason. When I opened it back up it wouldn't start unless I plugged in the power outlet - the thing had completely drained. Then I checked the battery and it says to 'Service Battery'. It's now holding a charge as normal as far as I can see but the warning is still there. Anyone had a similar problem? A couple of other things I notice too: - When I tilt the MBP to the right sometimes a scraping noise comes from the inside - maybe from a fan? - When I pick it up from the bottom, the bottom of the Mac dips inwards slightly and there is a click as it makes contact with something on the inside of the case. Are these things normal? I've made a Genius Bar reservation but I think I might just swap it for a new one. Is that ok to do in the UK?
