I confirm the previous post! It’s the third times I change the battery and I just realize this time that it’s completely useless to remove the front panel. You just have to be careful if it’s your first battery change because the original one is strongly sticked on the board. Don’t be brutal! Proceed slowly.
I think that lots of problem may occur when you reassemble the front panel cables. So just don’t disconnect them !
Ifixit is great. The comments are usefull too.
