MacBook Pro 13'(Early 2015) does not turn on with trackpad connected

Hello Everyone,

I have a MacBook pro 13” Retina, early 2015 model. It had liquid damage earlier and I did not find much repair information online back in 2015. I ended up damaging the trackpad and battery in the attempt to repair it. Last month, I replaced battery, trackpad and keyboard. Since then it worked for two weeks and now it refuses to switch on, even though the battery charger is green all the time. I did some research online and figured out that, if I disconnect the trackpad cable to the mainboard, the laptop turns on without keyboard. B. T. W, the replacement trackpad I bought from iFixit did not work the same way as the original one. It needed some extra push, was not sensitive enough for the finger touches, despite changing all the configurations. The trackpad cable was also replaced. Anyone had issues such as this?

Hi Dan and others,

I did not find a problem with the logic board. Since nothing obvious was shown up,

I wrote to the awesome guys at iFixit along with a video of the problem.

Today I received the replacement trackpad.

Right now, I am writing this reply from the MacBook, fixed and working like new. The important thing that I noticed is that the slowness felt on the other trackpad is gone and the system booted up. Now, the trackpad is like a normal new pad.

Yes! But its not the trackpad that messed you up!

The problem is the metal plate which protects the trackpad and supports the battery gets messed up when you take the battery out. So if you don’t flatten it out properly it will impede the trackpad from working properly. Here’s one source for a replacement MacBook Pro 13" Trackpad Insulating Cover

As to why your system won’t turn on sounds like the liquid damage within the keyboard wasn’t cleaned and now over time has caused the power button circuit to fail. Time to either replace the keyboard (a lot of work!) MacBook Pro 13" Retina (Late 2013-Early 2015) Keyboard or Uppercase with keyboard, Apple P/N 661-5233 which takes a lot less work. In most cases you need to replace the battery as well as you are likely to damage it in the process. It’s not just the outer case damage its also the stress you apply can distort the inner layers so while it works afterwards there is a risk the battery will rupture when the anode and cathode sides get too close!

Hi Dan, thanks for the reply. I had already replaced the battery and keyboard. It did work for a couple of weeks and then it stopped. Power button does work well once trackpad cable is disconnected. The metal plate as far as I have noticed do not have any bends, but let me check once. Thanks a ton and will post my response soon

Then focus on the logic board as it has damage around the connectors (corrosion)

@dan, Let me take a second look on that part. I will try to get photos.
