I'm probably not gonna move my MB all that much (at least not this semester), gonna use it for recording sound (therefore needing a quiet computer), and I was wondering what the drawbacks are when not using a battery. I've heard all sorts of things, but they all seem to be related to the fact that the power can somehow turn off in the middle of something - yeah, but that's the same with pretty much any computer, so that's not really the best argument. I also hear the CPU underclocks by a few hundred MHz, and that's not a hassle either. As long as it functions as it should otherwise. No point in having the battery in as long as it's not in use 90% of the time, and it works peachy without. In addition, I would imagine it runs cooler because of the underclock and the lack of battery making heat. This is nice, as I want to turn the fans down to bare minimum (buying 4GB RAM and a better HDD as well, that brings down the temp a few degrees as well). So, is there any real concerns with running it without the battery, and if there is, with it being plugged in while using the battery, what kind of strain is there on the battery (been hearing all sorts of things about the battery life of MB's - not positive any of them really)?
