    I was having problems with macbook pro mid 2012 (battery running out after a few minutes, showing 100%, trackpad not working well, not clicking, needed to restart computer twice each time it slept, etc)

    So, opened it and found the battery had swollen.
    (It was a no name brand)

    I've removed it, and now using it with power cable

    Was wondering if, apart from it running slow (because of clock speed I hear), is it ok to run it like this?

    It will be about a month before I can get another battery for it (I'm in a part of the world hard to come by macbook batteries)

    Any ideas if it's ok to run like this??

    Also, I've read it's not possible to increase clock speed, but on the chance someone has an idea to speed it up??

    Yes, it will run but only at 1/2 clock speed. Be careful with accidentally unplugging the power cord as doing so will make your mb shut off instantly

    Thanks for your superquick reply

    Do you know if there are any other dangers? Or if I'm careful, you think it would be ok to use this way for a month??

    One problem is that the MagSafe adapter gets disconnected very easily, by design.

    So be very careful with that power cable. A bump can mean instant power loss.


    BTW, I just had the same problem with my white early 2008 MacBook. The trackpad button was not clicking properly because the 10 year old OEM battery was starting to swell.

    I bought an Egoway battery off Amazon and it was swollen out of the box. I’m not sure if it was just a manufacturing defect of the casing or a true swelling cell but nonetheless it was defective. I then ordered one locally off eBay. Arrived 3 days later and it works fine although the fit isn’t as perfect and the colour is slightly off.

    Luckily though I live where it’s easy to get batteries. From the original battery starting to swell to my getting the third battery all happened within one week. However, it’s too bad that third party battery manufacturing is so crappy.

    Just to clarify, the power adapter alone cannot provide enough power for full clock speed so there really is no way around the running slow until you get a new battery.
