battery problem!!!

I have had my new mbp (2.2 ghz) for 5 days and already the max charge it gets is 97%!!!!! I need help/advice!!!!

 

I have a similar problem on my T60. This what I do when it happens. Pull the plug and run it off the battery till you get around 90% and then connect the AC adapter. You just need to reset the memory in the battery.

 

It interesting, I had that happen to me in a way. I had used my MacBook for 3 weeks, and then I calibrated the battery (by running it down), and when I charged it my MacBook said the battery health was only 96%. Well, I just left it as is and now the battery health is back to 100%.

 

You can do that as well Sam. I quit unplugging the battery when it read below 100% because the built in power management system in both OSX and Windows XP and Vista monitors battery charge levels.

My T60 battery also drops below 100% and if I leave it alone it charges back up to 100%.

 

My solution is very simple: Let the machine on with battery, using up all the battery by playing games or watching a movie, then the machine will go to hibernate.
You can then plug in the power. It will recharge the battery to 100%.
It works with my T40, do not know whether this works with mac or not

 

Hi Yessir, Just for reference the battery should charge to 100%, then slowly discharge to ~95% +/- 2%, before the battery will be allowed to be recharged to 100% again.

 

My battery went to 81% at some point. My macbook pro's 6 months old.

 

i know it's an expensive computer, but just take a shot of x-lax, relax that overstressed sphincter and realize that those meters are meant are not meant to be accurate to +/- 1 coulomb of charge. they are meant to provide guidance, not absolute values.

you have a 1 year warranty on the battery. if it goes way downhill in 6 months (ie, below 80% or something like that) call Apple.

 

Just use it on battery some again, then charge it again. It will fluctuate a bit, I end up anywhere up from 97% or so most times. You're fine.
