It’s going to cost $25 to dispose of the battery some places.
I didn’t do this. Mine never auto-booted before I replaced the battery. Now it does.
One YouTuber uses a fairly short narrow and small thin-bladed and very essentially flexible cake spatula to push in under the battery lobes never sweeping sideways. No chemicals except for 99% propanol to remove the adhesive residue.
Surprised by the tolerance of this little connector to my mistake of not flipping up the not very noticeable clamping element on side opposite to where the contact tip is inserted. The contact tip pulled right out without having done that. Saw in a video I should have done that before pulling the contact tip out. Remembered when reinstalling it.
My trackpad underside was dusty. Without thinking, I tried to blow off some of the dust. One washer and one double washer were finally found thanks to a bright flashlight and the contrasting color of the wood floor.
This cable can be carefully peeled off the battery by hand by those deft of hand. Gradually and inching along its length.
So this need to replace each and every screw in its exact former position explains exactly the excruciating difficulty I am having in getting the set of four shorter screws screws back in after everything else having gone successfully. Wanna scream at the top of my lungs. Maybe this point needed to be made in all ALL CAPS and BOLD for me. So can I still just start over trying each screw in each hole or have I messed up the threads in trying to screw in screws mismatched to their holes?
