Just wondering. i plan on using it clamshell style sometime soon and plugging into an external monitor. I've had a very bad experience with my last Macbook. Used it as a desktop system most of the time and one day I go to take it on a trip and the battery is bulging. Also, what is the best way to power it. I've already conditioned the battery and was wondering if I should let it run down most or all of the way before i plug it in, plug it in whenever, or leave it plugged in as much as possible. Thanks.
