Replacing battery in apple mac pro 2012 how to#
You may be already aware-of and already applied the solutions mentioned in this answer, but I'm including it anyway, so that other users with a similar problem can understand what options are there, and how to do it systematically. If new ones (new battery, new keayboard, new trackpad) are correct item for your exact Mac model# and still not working, then my remaining deduction would be, that, your Mac board itself has disconnected/faulty circuits near the area where battery pack is. New ones should work, & you may need to reset SMC and reset NVRAM/PRAM, see below details. Your sentence is not clear enough what exactly you've ordered-for, is it just the "ribbon flex" cable-conector, Or new keaboard & trackpad ? i would guess that you've ordered new keyboard & new trackpad (which includes new ribbon-flex connector). Heat expands different type of materials at different rate, so electrical disconnect, etc can occur from this. Trackpad's touch sensor may have developed cracks or some circuit has disconnected partially, so replacing atleast Trackpad may be necessary. When battery swell-up it pushes/expands upward, few components that suffer from this, one of them is Trackpad (aka: Touchpad), etc. Low-Quality and/or older-generation Lithium battery packs in Mac can degrade very quickly when HEAT or high-temperature is applied or around the Mac. The reason I'm suggesting that, as I'm suspecting, this connection is not stable in your case, and some pins are disconnecting when you're re-assembling back, as your comment indicates that you later also obtained new keyboard & trackpad, (so problem is not inside the keyboard or trackpad itself). Just do this extra step: Once you attach the ribbon flex cable connector (of KB, TP or battery, etc) onto Mac board's socket, then fully INSERT & slide it in completely into the socket, then use the lock mechanism in the socket, and put a tape on it, (tape piece should cover the socket and bit more area around it, and some portion of the flex-cable as well.) Replacing hardware parts (especially the TP), again, seems to be the remaining last option for your case. If before replacing battery, your Mac's keyboard & trackpad were working fine, then generally after replacing old battery, Mac MUST work fine, provided you've placed+inserted new battery correctly+completely, and you've made sure (old) keyboard & trackpad connectors are properly connected. Right now I'm looking for more solutions on how to fix my device. I've ordered a new one and installed it, didn't help. Some comments said that's a good alternative, I'm not sure if this caused the issue or not.Īfter the keyboard and trackpad became unresponsive, I've read that the Touchpad Trackpad Ribbon Flex Cable is very sensitive and it easily gets damaged. I did use Listerine instead of adhesive removal, because apparently shipping them is illegal in my country. This happened after I changed the battery and replaced it with an iFixIt battery while going over their tutorial. They work just fine, the problem is it's not a laptop anymore. I've connected an external mouse and Apple keyboard via USB slots. My Macbook's Keyboard and Trackpad are not working at all. The performance has significantly increased, however I have a new problem. I've changed my battery after this question:ĭoes battery condition have anything to do with macbook pro performance?
