Keyboard and trackpad not working on MBP 13" 2015

I recently got a MacBook Pro 13" Early 2015 A1502 where the keyboard and trackpad don't work. After a quick google search it shows the trackpad cable could be at fault. I also saw multiple posts saying these devices had a known trackpad cable issue.

On my MacBook the keyboard backlight comes on and I am able to press the power button to turn it on, however when the os loads it just asks me to connect bluetooth keyboard and the internal one no longer works. The trackpad has similar behaviour, when the laptop is off I can't click, however upon pressing the power button the click comes on but the pointer don't move and I am asked to connect wireless mouse.

While the trackpad cables are inexpensive I'd hate to buy one when the issue is elsewhere. Is it still the case of damaged trackpad cable?

You’ll need to use a USB keyboard and mouse/trackpad to check your system. Basically, you need to start the system and press the D key to enter into the onboard diagnostics. Let us know what errors you get if any

In addition, you should install this gem of an App CoconutBattery to check your battery as often the battery swells up pressing on the cables which in turn interferes with the signals. Post a snapshot of the apps main window here for us to see.

If you have the needed tools I would take the bottom cover off to physically inspect the batteries cells if they looked puffed up you really need a new battery. Review this guide MacBook Pro(13 英寸,配备 Retina 显示屏2015 年初期)电池更换 compare your batteries cells to what you seen here.

Update (03/23/23)

The last drive I did was a few months ago, I put in an OWC X2 SSD on a 15” retina system. Frankly, I personally haven’t really encountered that many issues with OWC. I think it’s been only one bad which I had gotten by the customer quite a few years ago, OWC shipped me out a fresh one quite quickly.

I will say many people have a hard time dealing with the OS recovery part as Apple jumped from HFS+ to APFS file system, Apple forgot to manage its recovery servers so when you try to do a fresh OS you get the older HFS+ OS which doesn’t offer the needed NVMe driver, so you get nowhere! I would need a few peoples fingers and toes to count how many people here have had this issue. But that’s not OWCs fault!

I’m sure the amount of returns is staggering! And I bet there is nothing wrong with the drives!

Which is why I always preach setting up a bootable OS installer thumb drive for your current OS, I think I’ve got a good dozen of them now setup and that’s what I use always! It’s even faster that the internet.

I also like sticking with the real McCoy! They are still available new! You just need to know where to look.

I just don’t like these M.2 adapters as Apple still has a few signal lines which are not compatible with the adapter/M.2 SSD setups. These are housekeeping services which fail once the drive is overly loaded up.

Basically, as this is a booting drive some files can’t be moved. This is the old shoe cobblers dilemma! You walk into the shoe store and you need a new heel for your shoe, but clearly the cobbler can’t fix your shoe while you have it on! Hence the dilemma!

Apple has a few tricks here to deal with that but without the data line it doesn’t work. Now the OWC and the Apple custom SSDs have these lines.

Don’t misunderstand, I love M.2 SSDs it’s Apple who failed us! But not sticking with a standard and if something was missing in the standard they failed to get it done!

Hi @danj, thanks for the input, in the end I bought the cable and both keyboard and touchpad work. Sadly the cable is a tad bit longer and I am having some issues bending it into shape. Kinda worried I'll break it. It's a laptop for parts that came without the top half (screen) so I can't do D on startup as it won't list any wifi. Battery is showing not detected. Bought it to swap my current i5/8gb motherboard with this i7/16gb one. It was really cheap.

Can I get your input on replacement ssd? My a1502 2015 13" has the oem 128gb ssd and let's be honest 128gb simply don't cut it anymore. What's the best alternative? I have 3 options:

1, OEM ssd taken from another macbook (probably 8 years old at this point)

2, Something like owc (still pretty expensive and i've heard owc is unreliable)

3, One of those adapters + standard ssd (Features like online recovery don't work etc + some adapters give up after a while i've heard)

完成的
