This is new to me.. just now saw it.

I had my 2.33/2.5gb ram/120gb HD macbook pro plugged in at work all day today and now while I'm sitting at coffee bean running off of the battery I notice a little "exclamation" next to it... '

"service battery"

This battery itself only has about 35 load cycles on it..

I ran coconut battery and it says the maximum charge my battery can hold is around 4200, down from 5400..

what's happening here?

Do I need to do a reset of some kind somewhere? faulty battery?

As the meaning of service the battery, i think its time to calibrate it.
Have a look at this page from  and they will run you through a battery calibration.

Battery Calibration

Hope this helps some

Cheers

I also noticed too that after my laptop sat charging at work. When I packed it up the charger (the charging block ) was warm as well. I don't remember this ever happening.

Try SMC reset Intel-based Macs: Resetting the System Management Controller (SMC), and also if you haven't updated to 10.6.2 yet (which from the thread you posted I assume you are on SL), download this.

Dont think that should be a problem. Im hooked into the wall 24/7 and mine is warm to touch. My battery life is also in very good condition. Just put your efforts into working out the battery problem

I did an SMC reset (removed battery, held down power button for 5 seconds, replaced battery and plugged in the charger)

upon boot up I still have " service battery" as well as the fact that my batter has dropped from 5000mah to 3800mah in 3 hours (total capacity) and typically I'd have about 2 hours of battery life left at 80% and now it says I only have 42 minutes worth of juice.

I may just leave it plugged in to the wall all night (the computer shut off) and see what happens. It is "charging" according to coconut which I guess is a good sign.

Could this just be a Snow Leopard glitch? per the forum I linked you guys up to above.

Well, I'd try calibrating your battery as per the link above by tattoedmac.

Secondly, I'd install the update I suggested, as if this is a software related issue, that will rectify it.

thanks 6string. I am currently running 1.6.2 so the software update I'm guessing won't do me much good. I'll try the calibration tomorrow while I'm at work and report back.

The combo update is structured differently, as well as picking up on any firmware updates that may have been missed, or not installed properly!
Combo updates should be installed over the top of stand alone updates when they come out, as they seem to fix minor glitches a lot of the time.
This was the case also in leopard, tiger, etc.

six string, I'll try and do the combo update right now.

Yeah, it's running a 2gb chip and a 512mb chip.. I'm going to put another 2gb chip in here (even though i'll only get 3gb worth).
