    I have a Mac Book Pro 13" mid 2011 that have some really strange issues;

    - When moving the cursor, it moves irregularly and lagging.
    - The computer is slower than it should be.
    - The battery is not charging, the magsafe connector is lit green. Battery status says "0% Battery is normal, Not charging".

    Because of this, I replaced the drive with an SSD and I bought a new battery. It worked good for a couple of days, but now the problems are back!?

    I have reseted PRAM and SMC to no avail. (How do I *really* know that the SMC is reset?)

    Any ideas?

    PS. I have started on another drive, and the lagging persist, which indicates this is a hardware related problem. Very strange though...

    PPS. I downloaded iStat and the battery panel says as follows:
    0% - Calculating
    Not Charging
    Voltage: 11050 mV
    Amperage: 0 mA
    Condition: Normal
    Cycles: 2
    Health: 86%
    Design Capacity: 5770 mAh
    Current Capacity: 4975 mAh

    More update:
    I disconnected the battery and then the lagginess was gone.

    So, the question is: Is this due to a bad battery or a bad DC board? Is there some way to measure the DC board without removing the logic board etc (I have a multimeter)?

    Just a quick question, are you using the adapter that came with your Mac?

    Yes. I have tried with two different ones. They both charge my other MBP, so the adapter seems to be fine.

    Update:

    I have tried with yet another battery, and another DC-board that is working good on another Mac.

    It isn't slow anymore, but the battery resist to charge.

    So, I guess it's the motherboard then... :(

    Is this a common failure? Should I try anything more?
