I purchased this trackpad over a year ago and have used it daily since. The item was never dropped or damaged, but the other day it just stopped working. I click the power button and nothing happens. No green LED, no connection to my MacBook. I replaced the batteries several times and tried cleaning the contacts for the batteries inside the device. Nothing has worked. Apple support recommended I take the item in to an Apple store so they can “look at it”, but before they try to sell me a new one, I’m wondering if anyone has had success in reviving these devices after they die. Thanks
Probably not for the average DIYer… take a look at the tear down - on the right - there really isn’t any user serviceable parts. It takes a lot of practice and skill to remove/replace components on a circuit board, and that’s basically what you’re dealing with. See what sort of price Apple gives you to repair, replace it. Sad to say but with all the glue it’s really not a repairable design. If this answer was helpful please remember to return and mark it Accepted.
Mine had same issue. I forgot to turn it off, and it had batteries corrosion. I replaced batteries, it still worked, but after several days, it stopped working and the light wasn’t on any more. I use a long stick wrapped with cloth and dip a little bit alcohol to clean it inside. And then magic happened, the light came back on! Hope it will help you. :)
