Macbook Pro Mid-2014 trackpad stopped working

[RuiLoureiro]

My mid 2014 13" macbook pro (retina) has been acting really weird. Two days ago after I powered it up, the mouse started going crazy, moving all over the place, and eventually stopped moving, and my trackpad hasn't worked ever since. I'm using an USB mouse works flawlessly.

My keyboard is also strange ever since, often not registering my key presses. After searching several forums, I found some users who reported this happening when their battery started swelling, but my trackpad still clicks fairly normally, which didn't happen in some of the cases I've seen. My battery is infact in 'Replace Soon' condition, with 1200 cycles. I've posted a screenshot of CoconutBattery bellow.

Already tried SMC and PRAM reset, without success.

I've ruled out sending it to Apple, since they charge me 300€ because they have to replace the entire bottom frame.
I'm thinking about ordering a battery from iFixit. Do you think this might fix my issue? Do I also need to replace the trackpad/keyboard cable?

Any experience regarding similar situations is highly appreciated.

You won’t know what else needs to be replaced, until you start replacing other things, to rule them out. So start with the least expensive replacement pieces.

Why do they have to replace the frame?

Why do they have to replace the frame?

Apparently because the battery is glued in, so they only replace battery + trackpad + keyboard.

Unfortunately this is the way Apple is building their latest portable Macs and iMacs. (lots of glue) Battery replacement according to Apple requires the top case to be changed out and that includes the trackpad and keyboard. An expensive repair.
