I got a 2017 13” MacBook Pro online for parts. The fans gradually ramp up and spin at full speed when plugged in. The trackpad connector was ripped off of the board and there is no ssd. Water damage indicators are also red, but no visual marks or stains. I get no image on the display, caps lock key does not light up when I press it. When unplugged, the system immediately shuts down. Any help?

My display backlight was working perfectly just a day ago, but ever since I connected the display into another MacBook I was testing the backlight completely stopped functioning. I already swapped the small cable that connects the display board with the logic board and have also tried SMC/PRAM reset without luck. Connecting another display to the MacBook shows nothing either (this screen was untested however). Any help?

I’ve looked on windows to see if it was detected in device manager and it wasn’t detected, nor was the sensor.

System information in MacOS says it doesn’t find a connected camera

I even booted Ubuntu and checked with the Terminal command, and it didn’t detect it there

This only happened because I connected my screen with the battery still connected…

I have 2 broken top cases are with 2 known working cameras and both aren’t being detected. What should I do? I’ve had my head wrapped around this for weeks, I’m losing hope here :(

I suspect the issue may be the battery ribbon cable, which I’ve already ordered, but I wanted to see if anyone else has experienced this or knows what the problem might be.

Thanks in advance!

Added a new battery today and not Good so far.

The device only powers on with power cable connected.

It won't turn on straight away when I press the power button, if takes a minute or so then comes on.

When I originally put the trackpad back and notice a spark, would this device be shot here even of its turning on at the moment?

I've also just ordered another BMC flex cable.

Help appreciated

Here you go on images

UPDATE - Just noticed I didn't unclip the BMU when removing.

Also, the connector to the battery board came out when installing.

1. Could these be broken if yanked out not pulled out with the clip open?

2. Does a new cable solve this? If yes I'll need to wait a few days till it arrives to conclude on this!

3. My god Apple complicate things on mainboards lol. You need to be Tom Thumb

Update - just tried multimeter on new battery and got readings so suggests it isn't a dud battery?

I've got the laptop from a friend that said that he spilled some coffee on it. Currently the device won't turn on not matter what I've tried.

I've opened the backpanel and saw that the track flex connector seems a little burnt and the ZIF connector on the board itself seem to be broken.

I've tried to turn the device on while the trackpad is disconnected without any luck.

My question is, could that prevent the device from turning on? Or there might other issue be causing that?

Thanks.

I have a very strange issue on the macbook

Issue is

Charger gets plugged in with am-meter and it shows 5V>20V and 1.5A on battery and approx 0.6A when the battery is disconnected.

PPBUS_G3H is present on F7000 on both sides and when in Ohms mode readings are expected

Nothing is shown on external monitor and caps lock key doesnt light up

The CPU gets very hot,.

Any advice please

I have a 2017 Macbook Pro 13” function keys. Almost 3 weeks ago, I was using my laptop then all of a sudden the keyboard and trackpad stopped working. Even during boot, it does not recognize either of them. I cannot run SMC reset or anything. It is currently stuck in recovery mode telling me to turn on my mouse or trackpad since the internal device is not detected. I tried connecting a mouse and keyboard and the mouse worked fine, but I think the keyboard I was using was acting funny. I am going to try and get a hold of an Apple Keyboard and Trackpad or Mouse and see what I can figure out with an SMC reset and Apple Diag.

I took it to an Apple Store about two weeks ago, they took it to the back for 10-20 minutes, and couldn’t get anything to work. They didn’t give me many details on what they did, other than checking the connections and reseating them. They quoted me almost $500 to get it fixed because they were unsure if it was the trackpad and keyboard or logic board, but for double that I could buy a new laptop, so of course, I walked out.

I work on computers for a living, so obviously I’m fine with working on these, I was just seeing if I could get some free diag from Apple, but nope. Has anyone had a similar issue? I plan on running these commands tonight, hopefully, to see what I can come up with. I will post the results.

Thanks in advance,

Austin D.
