How to change the Battery

You will need to firstly take out all the external screws holding the back case on and then the ones around the battery holding it in (screws can be different sizes so make sure you remember where they go), carefully remove the ribbon connector at one side, then lift out the old battery with the tabs and replace with the new one plugging the ribbon back in and clicking into place then just return all the screws to their holes and replace the back case.

I think videos show this sort of thing best so I've included links below;
