battery not working properly after upgrading to 10.8.5

Hi guys,

i have upgraded recently to OS X 10.8.5 and now battery charge is always 0% and battery charging light in green state; system is indicating "replace now" as battery condition;

the thing is that, before the upgrade, even if battery was not lasting more then 50 minutes (400 and more recharging cycles), it was fine;

now when I plug the power cable and boot the laptop, it seems is trying 3 times to boot;

I did check and I have the latest SMC firmware; trying to reset it as described in

http://support.apple.com/kb/HT3964

did not work.

I suppose i have to bring it to the support but anyone with a similar issue?

Thanks

G.

MacBook Pro, OS X Mountain Lion (10.8.5)

The maximum cycle count may depend on which MacBook Pro you have > Mac notebooks: Determining battery cycle count

Thanks for your reply; by looking at the table, maximum cycles should be 1000 (my counter is on 471); this seems to indicate the issue is related to the upgrade I did last week; that's when I've started to see the issue.

Not necessarily...Just because it says that your battery should be 1000 cycle capable, if there is a problem with it, it isn't going to make the 1000 cycles. Sometimes things can have flaws that don't always make it as long as the "should" make it. Sounds like you were stating in your first post that the battery only makes it 50 minutes. This is not a normal situation for the battery and if this is the case there is a problem. Just may be the that the new upgraded OS is picking up on this issue where as the other one didn't which makes it seem like the upgrade caused the problem. If you can, take your computer to an Apple Store and visit the Genius Bar and have them take a look at it. They may be able to fully shed some life on your situation, but it does sound to me as if your battery is done.

Thanks for your reply;

yes, the update raised is probably picking up that my battery is not anymore in good condition; as it is indicating "replace now" as condition and Apple documentation states:

Replace Now: The battery is functioning normally but holds significantly less charge than it did when it was new. You can continue to use the battery until you replace it without harming your computer.

Saying "functioning normally but holds significantly less charge", I would expect the battery to keep at least the 50 minutes of charge (as before the upgrade); but now is not re-charging at all (0% always and green light status); and the consequence is that as soon as I unplug the power cable, the laptop will die. So I still believe there was something with the upgrade and the SMC firmware (my mac is a MacBookPro.8.2 early 2011).

Thanks
