Anyone out there use their MBP in a Club environment night after night where it is exposed to Cigarette smoke? If so, have you experienced any problems? We've had battery issues with a MBP since we got it 2 years ago. It is covered by AppleCare. My son started using it to DJ with since May. I have been told everytime the notebook goes in, that "next time" they will replace it. Now that it's being used in a club environment, they don't want to replace it. They want to blame the cigarette smoke in the night clubs. Of course this doesn't discount the fact that prior to this I have pages of documented instances of power failure issues. So, if you smoke or work in a smokey place, do you have any issues with your MBP because of it?
