I had not been able to change the battery so far, for lack of T0 screwdriver.
Well, it's done now :)
It took me 5 minutes total, to remove (and replace) the cover screws of ten, and the 3 screws from the battery. And besides, I did not know I could use the plastic spatula to lift the battery connector, which is driven into the motherboard. Although bothered otherwise.
So perfect !!
