MacBook Pro promblem

so if my laptop isn’t plugged into power, it shuts down. it’s about one year old.

it doesn’t go into backup power or even give me an alert, and while my battery is sometimes plugged in for 4-5 hours at a time when uploading images, it retains next to no energy when at 100% (it used to drop rapidly; from full to 15% in about 30 minutes with monitor at half brightness, while doing simple things like e-mailing). now it just crashes.

i’m gonna buy a new battery, but should it just crash when it’s at 70%+?

Yep the battery is finish, if you have a new one, look there was a battery update for the powerbook and i had it ones time that the battery is still under guaranty ?? in one year try to chance at the locale Apple repair office ?? If the battery is real empty put it for 2 day in the freezer the molecules will chance/move and some time it works ?? if you get him out of the freezer let it warm up before you start charging it.

Happened to me a few months ago. Definitely the battery.
Be sure not to let your MB Pro plugged in all the time, and as Apple states: “keep the battery juices flowing”

change your battery view preference to time rather than , and you’ll see 70 of nothing is, well nothing…

There waa a batch of batteries that was bad, and are covered under warranty. Info here:

MacBook Pro batteries have been pretty bad – I’ve had to replace two so far.
Go to the System Profiler (Apple > About This Mac > More Info…) and check the battery condition under the Power section. They are supposed to retain 80% of their original charge up to 300 cycles. If yours has done less than 300 cycles then take it to an Apple Store and they will replace it for free (going on past experience).

thanks for all the helpful advice! i ended up taking it down to Apple and at 281 cycles, they said it was failing and swapped out for a new one. i also bought another battery for traveling so everything worked out.

i’d like to say, like ed, that while lightstalkers has shown signs of detriment, it has also proven itself a fantastic resource for a variety of issues, both technical and otherwise. thanks, dudes.
