    Yesterday, I was in a client's office with my ageing MacBook pro (see model in sig) picking up some files for a job. I'd forgotten my power supply and my battery was getting a it low so the client offered me their mains adaptor to use. It was one of the newer models, with the new style MagSafe socket.

    Anyway, I used it for about an hour before I came back home to start working on the job. I used the laptop when I got home to get the files I needed from the laptop to the desktop machine and then put it to sleep.

    Today, I went to switch the machine on and there was no power at all, no LED on the front and no chime / waking when the power button was pushed.....Completely dead. The red charging light comes on when I connect my power supply to it but interestingly, the battery doesn't seem to be charging.

    Anyone have any idea what the problem is? have I fried my MacBook pro by using a new mains adaptor with it? Seems a bit coincidental that I have a completely dead laptop with no signs of power so soon after using a different and more modern PSU.

    Obviously it's well out of guarantee, even with AppleCare and I have a feeling a genius is just going to give me the new logic board / time to upgrade line if I take it into an apple store.

    That should not have caused the problem - we often share power adapters in our family (going from 2008 Macbooks to 2011 Macbook Pros / Macbook Airs and all kinds inbetween) and they all work fine. Yes, if you plug a Macbook Pro into the 45w Macbook Air adapter then it charges more slowly, but it still charges!

    My guess is that it's co-incidental.

    I had the same symptoms with my 07 Macbook: I have put it to sleep with low battery charge, the battery drained over night, something must have went wrong as it didn't go into hibernate mode and completely drained the battery (and as a result killed it, it was simply no longer recognized by the Mac). The battery was pretty new at the time, so I got a replacement under warranty and have since stopped using sleep mode for long times with low battery charge. ;)

    So, chances are good that your Mac is doing fine, but that the battery is dead. I would therefor buy a new battery and hope for the best. The Macbook chargers are interchangeable and most likely not the source of the problem.

    Hmm, thanks for the replies. Thing is that the battery indicator lights are showing that the battery is about 70% charged....but it doesnt seem to be charging anymore.

    Going have a think about it and try messing about with it tomorrow.....maybe it just doesn't like Tuesdays.
