My 2009 MacBook Pro has suddenly stopped charging. I have two power cords, and their of them light up when plugged in. The battery icon at the top menu bar has the charging symbol, but next to it it says (Not Charging). I have 0% batter power left and it is recognizing the Power Adapter. Has this happened to anyone else?
Thanks!

MacBook Pro 2009, Mac OS X (10.5.8)

    Reset the System Management Controller and see whether that changes anything:

    Thank you! It took a couple of tries, but I'm charging again. Thanks again for your time.

    I had the same problem but with me the SMC reset didn't work. I found a lot of people claiming it was caused by Snow Leopard (strange idea of course, you'd think this is a hardware problem at the most, but maybe the OS does regulate the charging hardware..). I tried what some claimed to be a solution, namely install Leopard on an external harddisk and boot from there, but it didn't help. I went to the shop who told me to buy a new battery, which I did - everything works again. But, being an engineer, I took the old battery home and, of course, opened it. The interesting thing is, that the Li-ion cells still produce 9-11V, but there is a circuit board in it as well, and that one is faulty. The voltage from the cells does NOT reach the outer contacts. I looked for mechanical problems on the circuit board, but couldn't find any. I checked the temperature sensor, but it also seems OK. Checking the components is too much work so I give up. But it's a pity a EUR140 battery can give up because some $1 circuit board inside fails.

    I have got the same problem. I plug in the MagSafe but the light does not turn on and I can see the Power adapter connected but not charging. I have tried to reset PRAM and SMC several times with no result. I have read it is a common problem. How can I solve it? It is changing the battery the only option?

    Thank you!

    I suddenly encountered this problem with my 3 month old Macbook Pro. The computer works fine when plugged in but instantly shuts down when unplugged. We took it into the Mac Store (Chestnut St, San Francisco) to be fixed and they ordered a new part. When the part arrived at the store 2 days later we dropped off the computer to be fixed. It's been about 5 days and still no computer. Perhaps a better forum would be one to complain about waiting for the store to fix things, still we are very frustrated with the process. Not too impressed with Apple after switching from a PC.

    Have you called the STORE to ask THEM when your computer will be ready? There isn't a thing any of us here can do to help you.

    Thanks

    Sindar, if your problems are as you say they are, then the answer is blindingly obvious given that your computer is well within warranty!. Take your computer and charger to an authorised Apple service centre and get the problem fixed for nothing. Try http://www.apple.com/es/ for locations or simply take your computer back to where you bought it!.

    Cheers

    I would like to tell you how has finished all my troubles. Yesterday I went to an Apple Service and after trying a new power adapter it worked, so the problem was the adapter and I have used the warranty to change it.

    Thank you

    That is great, Sindar! Glad you got it sorted out.

    Had the same intermittent problem with my new 13" macbookpro too, fixed with a new power adaptor too - guess there is a problem - anyone else having a problem with an older macbook pro 2006, replaced the power adaptor but now will not switch on - been told its the logic board but @ 800-900$ I am not v happy about it at all
