hello all,

I just replace my ac adapter from the apple store. before replacing my old adapter was damaged and wouldn't the battery. Now that I have new ac adapter plugged in the computer doesn't charge at all. The light on the end of the cord is always green. What could be the problem?

How old is the computer? The green light on the adapter should mean the battery is at full charge, but perhaps the battery is fried, or needs to be cycled.

the computer is prob 3 or 4 years old. I bought it used. When i go to unplug the adapter from the computer it will shut down the whole computer like it is dead.

The computer is not dead. Your battery is. Try Coconut Battery to check status of your battery.

That sounds like a battery that's dead, and will no longer hold a charge. I'm almost at the same point with my current notebook. (Where, oh where, are the new 17" MBPs?)

That said, before shelling out money for a new/used battery, you might want to stop by an Apple store and see if they'll put another battery in your computer for a minute, to see if your computer will work with a different battery installed.

It claims 0 load cycles?!? That ain't right. I'm not sure even brand new batteries have 0 load cycles. Either your battery is toast, or the part of your computer that interfaces with the battery is way messed up.

Reset the PMU.

I had the same problem with my black MacBook. If it was run completely flat, and then maybe left for 12 hours before being plugged in, then it would no longer charge.

I had two batteries replaced by Apple. One was via a retail store while the laptop was 10 months old, the second was at an authorised reseller 4 months later. The Apple store had said they would not replace it again 'cos it was out of warranty, even though the "new" battery was only 4 months old.

However, the reseller said it was a known problem and he got me the replacement battery within 5 days. While I was in there and we booted up the MacBook to check it, I mentioned that the click button was broke and you have to use the trackpad tap. He said it was another known problem and that even though the computer was out of warranty he might be able to get a "S" code or something, which basically means that he could send the laptop off and get everything fixed.

I was very thankful but declined - my MacBook is just a "surf the net while watching TV" machine now.

If it's an older iBook or PowerBook, follow the instructions at that link. Instructions start about halfway down the page.

If it's a MacBook, MacBook Air, or MacBook Pro, see here: Apple Portables: Resetting the System Management Controller (SMC)

MacBook, MacBook Pro If the computer is on, turn it off. Disconnect the AC Adapter and remove the computer's battery. Press and hold the power button for 5 seconds and then release the button. Reconnect the battery and AC Adapter. Press the power button to restart the computer Note: Starting with MacBook Pro (Late 2008) and MacBook (Late 2008) models, you may instead use the reset method for MacBook Air (below) to reset the SMC. All earlier models of MacBook and MacBook Pro must use the method described above, which involves removing the battery. MacBook Air If the MacBook Air is on, turn it off. Connect the power adaptor to a working power source. On the MacBook Air keyboard, press (left) Shift-Control-Option along with the power button once. Note: You must use the keys on the left side of the MacBook Air keyboard. Wait 5 seconds and press the power button to start the MacBook Air. Apple recommends only performing an SMC reset when the MacBook Air has been properly shutdown. This prevents issues from occurring to the file system. While the power adaptor does not need to be connected to reset the SMC, it may be necessary in situations where the battery needs charging, or the MacBook Air has been without power for an extended period of time.
