that’s it, really. my Magic Trackpad died; I’ve not done anything exciting with it; regularly replaced batteries, not anything obvious to see; but it’s not powering up when I press it on, so I’m suspicious it’s something power related. Any ideas on how to trouble shoot/repair it. I’m bereft as I love it a lot and use it all the time!!
Spy down the battery compartment do you see anything like corrosion? If you do you’ll need to clean it out using some White vinegar slightly damped cotton swab. Then get a pencil with a pink eraser which is still soft. I like the larger diameter ones for kids! Shove the pencil down eraser first, now with a bit of pressure spin it around scrubbing the contact and do the same on the lid. That should do it!
