2 What is this burnt chip/capacitor next to the Trackpad connector?
Hi! I tried to replace the battery in my Wife's A1706 Macbook pro 13. After checking and testing everything, it became clear that the new battery which was sent to me was faulty (...) so I will get a replacement (Tried it with the original battery and it was working fine so I didn't mess that up :D. During the replacement, the Trackpad connector slipped out slightly so the fans turned on and the machine became extremely slow. After read a solution, I slipped it back and it worked again (yay) - though I realized, I haven't hooked the ribbon cable through the battery so I turned off the macbook, pulled out the ribbon cable, hooked it through the battery and when I wanted to connect the ribbon cable back to the motherboard, a small capacitor/chip/whatever catched on a little fire (WTF) during my trying to connect the connector to the logic board. :( It was my fault because I forgot to unplug the adaptor after turning the macbook off.
I downloaded the schematics as well, however, I haven't found on the schematics what the hell is this little thing and I cannot read it because it is quite small.
Could you please help me identify, what is this little thingy? Do you think this can be repairable/replaceable? Hi! I tried to replace the battery in my Wife's A1706 Macbook pro 13.

Many thanks in advance. I was so stupid that I left the adapter plugged :( And I'm mad for the battery provider, because if the battery works as expected, I wouldn't left the adaptor plugged in the first place (and the icing on the cake, I ordered the replacement battery almost 1 year ago and I decided to replace it now and by now, the warranty is out of the question...
I hope this macbook still can be saved :( :( :(
Thank you!
Esta é uma boa pergunta?

Hi All,
Thanks for your replies. Hey Oldturkey, thanks for your specific reply! I checked the schemazics one more time and its just too complicated for me, I cant even find the trackpad connector in the drawing XD
Anyway, I’ve found on aliexpress this item only:
10pcs 74LVC1G08GW VE SOT-353 74LVC1G08 SOT353 74LVC1G08G SOT
https://a.aliexpress.com/_m0o5mYw
Do you think this would mean if I would (or the guy in service) replace this one transistor, the problem would be solved? :)
Many-many thanks in advance!

@Kálmán Dávid it's not a transistor, it's aGate :-))
I don't see why they couldn't. It is not a terribly complicated job and somebody with the right tools and skills can do that in not time. Looks like the part from Aliexpress might work :-)
Oh, and to find the component on your schematic, I am assuming you have a PDF file, just use the search function for your reader and type in U4530
Go for it. You got this. Remember

@Kálmán Dávid Just to add some information to @oldturkey03’s excellent answer below and comment here; Finding something on the schematic can be very tricky, unless you know the components designation (in this case U4530). Getting a hold of the board view file that goes with the schematic, and then using a good board viewing software (I prefer Paul Daniels’ flexBoardView, cost money) is the best choice. This file shows the layout of the components on the board, and you can easily navigate to the right area and component. I like FBV because it links the board view and the schematic, and lookup is easily done. Just a nice little tip ;-)
As OT said: You got this!! Repair is WAR on entropy!

Hello @oldturkey03,
I’ve found this transistor and bought it, though I’ve also found a local service who has more experience by soldering such small components.
They told me that it does seem that the CPU is short circuited and it seems that the whole motherboard needs to be replaced. :( I told him that the transistor burnt out in front of my eyes - so they haven’t replaced the transistor yet.
Do you believe by any chance that the CPU really got short circuit-ed by connecting the trackpad connector to the motherboard?
Its especially a pit one because this is the highest end model with the strongest I7 cpu with 16GB Ram and 1TB SSD so if the motherboard would need to be really replaced, then I’m officially &&^&@@. :(
I’m so mad at myself that I made such a dumb fail. :( :( :(
If thats the case, is there any chance to replace only the CPU? Based on Google, I saw that ita merely impossible, though I can see 1 or 2 video about that..
Thanks for your support.

@kalmandavid let them fix the destroyed Gate (it‘s not a transistor) first. I am not sure how they determined it us the CPU. Of course, anything is possible, but first fix what is definitely broke. Then re-evaluate. I am sure there are some people that could replace the cpu but they will be hard to find. Replacing the board would be most likely the better option. Fix what‘s broke. Don‘t go by could be and nay-sayers yet!
