They're all the same. Just locate the battery and you just push down on it (softly I might add) and depending on your motherboard you'll have to loosen some pins or somehting.
well, i would suggest not removing it yourself, take it to a shop and have them do it. dissasembeling a laptop and reassembeling it takes time and you are almost certain to lose a screw or 9 along with not being able to fit everything back in.
