I was going to post a really long essay, till I came across a post where someone said that Macbook Pros automaticly downclock their clock speeds unless both A/C power & battery are connected. Tested this out myself and it appears to be true. Can anyone here tell me how do I run my Macbook Pro at full processing power when just connected to A/C, without having to put my battery in? Or to run it at full power even with just my battery alone inside? Also, does leaving my battery inside while on A/C power kill the battery life? I heard many many different opinions. Some people advice me to take it out, whereas others tel me that it doesn't matter for lithium batteries.
