I've had my Macbook Pro for about 3 months now, I haven't had any problems with it... except my battery life sucks but everyone's does so no biggy.

Anyways... in the last 2 days my computer has been acting really weird.

It will be at around 30% and it will say that I've reached the reserved battery... which normally it waits until around 12% to say that. THEN now it's shutting itself off around 30..... so I'm thinking that the display is messed up and it's displaying 30% when it's actually 12... so on so on. Like right now it says I have 100% power but this isn't possible because I've been on it for about a half hour now without it plugged in.

Has anyone else experienced these problems? I've turned it on and off ... no help.

Yeah, my battery is weird too. Here is the post I did about it

What is wrong with my battery?

Now it is back up to 5300. I will bring it in to the shop for them to have a look. Maybe I can get a new battery out of it.

I had the same issue. There was a battery update from the apple's support website it helped a little, but in the end it was in the batch of batteries that was recalled. But I called Apple and they replaced the battery for free and everything was fine after that.

Hi,
Had my Mac Book Pro (Santa Rosa I think) for about 2 months now and been fairly pleased with the battery life thus far - until this week.
After using it from fully charged to about 40-50% or there abouts, and then putting it into standby for a while (lets say an hour), when I wake it from standby it would immediately go dead. Battery indicator on the battery itself would flash to indicate dead and thus couldn't wake it again until I connect the AC cord. Sure enough the on screen battery indicator shows 0%.
Firmware and battery updates are up to date (1.3 and 1.2 respectively). This has happened a few times now and it's getting a bit annoying. Came across an article on Apple Support: http://www.apple.com/support/macbook...batteryupdate/
Looks like I'd be eligible for a replacement battery due low performance (cycle counts only 46) but I wonder does anyone have any suggestions first?

Cheers.

Update: Been doing a bit more searching on the forums and found out about a program called coconut which looks handy. Says 2171 max capacity, 38% of original capacity. System profiler says this too, doesn't sound good but maybe it needs a bit of time to calibrate etc.
BTW, would anyone recommend resetting the SMC? sounds like a last resort.

Ask Apple for a new battery, you will get one without any problems.

Ya, apple reseller where I bought it is only up the road so they should probably sort me out - on the other hand if I ring them and they send me a new one, am I obliged to return the old one!!!!

Spent half an hour on the phone to apple today - very helpful and knowledgeable. The guy took me through all the usual steps, resetting the PRAM and SMC etc. As we were doing this, I noticed the battery itself was buckling outward! He checked the serial number of the battery and it's one of the ones being recalled so I must bring it to an service provider for replacement.
