MacBook not turning on after replacing trackpad cable

macbook prorepair

I have a MacBook Pro (early 2015, 13"). About a year ago, the keyboard and trackpad quit working. I took it to the Apple Store and they said it could be that the cable went bad. They also said they may have to replace the whole bottom casing. I figured if it was just the cable, it would be worth me fixing it by myself. I'm not the most experienced MacBook mechanic, but I generally know what I'm doing.

Anyway, I've been using the MacBook with an external mouse and keyboard for a year. I bought a new cable for the trackpad, but after the replacement the MacBook won't even turn on. I switched back to the old one and it still won't turn on. What could have gone wrong? I've unplugged and replugged the battery, used two different power cords, etc..

Listen buddy i have a similar problem. When you changed the ribbon cable you have probably forgot to remove the cable for the battery. This is why probably your battery went wrong. I also changed the ribbon cable myself and managed to unplugged my battery. This however did not fixed my keyboard and mouse issue (wish it did but it did not) but when i tried to turn it on it was just fine. I would suggest you unplug your battery leave it for few minutes check any cables around take off the ribbon cable put it back on. Then plug the battery properly put the protector on and try to start your mac. If that does not solve your second problem then you better start browsing for a new laptop.

MacBook – Trackpad and keyboard of MacBook Pro unresponsive

While I agree with Tetsujin that you need to ask the repair shop for details, it probably helps to understand some terminology.

"Top Case", at least to me, is a bit of a misnomer. You would think it would be the "top" or the case around the screen not the part that has the keyboard assembly...but hey...it is what it is.

Anyway... the top case is the general term for the entire assembly that has the top cover of the Logic board, the keyboard, track pad, and power button.

When there is an issue with any one of these components, people generally say "it's the topcase" because it is royal PITA to change the individual components out. However, on the MBP 2014 model, you can replace the trackpad w/o disassembling the topcase. It still is a PITA, though.

Here are some instruction on that repair for your reference.

Now..... "why did it go bad?" Any number of reasons from liquid damage, hitting it too hard, or it just wore out.

Is it defective and can you get it replaced? Yes.

The follow up question is "is your MBP under warranty or AppleCare?" If not, then you will be paying for the repair out of pocket.

I hope that sheds some light on the problem.

Macbook Pro Mid-2014 trackpad not working

I would remove the battery and rely on the power adapter. You can try resetting your SMC, this fixes a lot of hardware and power related issues.

◦   Shutdown the MacBook/Pro and remove the battery
◦   Disconnect the power adapter, hold the Power Key for 10 seconds
◦   Release the power key and reconnect your battery and power adapter
◦   Turn your Mac on
◦   Let boot as usual
