Will leaving my laptop plugged in all the time with the power cord and battery ruin my macbook or battery? i pretty much use my macbook as my desktop so it is always plugged in. is this bad?
 
Thanks yes I'm aware of calibrating , but DeusInvictus7 answer to the question is wrong as it's safe to leave your notebook on AC 24/7

Leaving my old Dell Inspiron plugged in severely degraded my battery capacity over time. When it came time to actually use the battery (I had 2 in this particular model) they wouldn't last more than an hour.

I believe DeusInvictus7 is correct stating it is not in the best interest of the battery to keep the notebook continually plugged in.

thats exactly what i was saying...i had two laptops before my macbook, and both of them were plugged in pretty much ALL the time (they were my uncle's and he used them in his office) and when he gave them to me, the batteries only had about 15 mins of charge on them...

Well I'm sorry but i believe this to be incorrect, my spare MBP ( a 06 model ) has 92% health at 72 cycles and is left on 24/7
 
ALL the time...yes

just make sure you run it on battery like once or twice a month or something...that should keep it pretty healthy...

No it doesn't. I ran in clamshell mode for nearly 4 years constantly. I would occasionally unplug and use the notebook until it was fully drained to help calibrate it (once or twice a month). But otherwise, it was fine. Actually, I am still on my original battery. (the one given to me after the 2005 recall that is)

iStat shows my battery on my 2005 Powerbook @ 91% Health, 63 Cycles, and 97% charge.
 
You have to give the battery a little bit of a work out :D AT least once a month seems to be the overall opinion in order to maximize its life span.

well see you kinda just made my point...you did unplug it and drain it once a month right? thats what i mean...
