    Is it really necessary to disconnect the battery plug when upgrading ones hdd? All the ifixit guides say to do that but is it really needed?

    I didn't unplug it and everything was ok. Just make sure you're careful and go slow.

    It's a safety precaution to help prevent electrical shock. So if it's necessary or not depends on how careful you are;)

    It's not a safely precaution for the human, rather safety for the laptop.

    There is nothing I can think of in a modern LED backlit laptop that would shock you, on older laptops if you got hold of the backlight inverter while the capacitors still had a charge it might make you jump, but thats about it.
    The main reason to disconnect all power is if you drop your screw driver, or even a screw and short a power pin to something sensitive you could take out your laptop...

    It's well worth pulling the battery connector, takes a few seconds and makes it a much safer operation.
