I have a 2.0GHz Core Duo Macbook, and Ive had it for about 3 years. However, is these 3 years, I have gone through 2 batteries. The story goes that about 1 year after I get a new battery the capacity goes down alot. Now it barely holds its charge for 5 mins. My old battery died completely. WTF is going on? Im getting a MBP 13 soon but I just want to know what the **** is happening.

Have you tried resetting the PMU?

There is no system but GNU and Linux is one of its kernels.

Do you often completely drain it and then recharge?

Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

Not often. You think that was the problem?

If thats the case what measures should I take when I get my new laptop so the built-in battery doesnt take a dump on me.

No. If that was the case, I'd think it was the cause. Completely draining and recharging on a regular basis will shorten the battery life. Apple does recommend doing a deep discharge once a month to "calibrate" the battery, but you don't want to do it too frequently.

I know about the calibration. So still now idea as to how this happens? When I get my new Pro Im going to calibrate it in the first day. Then after that charge when ever under 20%, or over night. Is it recommended to keep it plugged in when at a desk, or not using it?
