I bought an Apple Macbook Pro 100$ on E-bay let's see if I can fix it for a profit.

[@Shaker-Hamdi]

You got yourself a new subscriber. Keep it up. Just try to use a microscope camera for a closer view on the components you'r testing, like the fuse for example.

[@macbookfixer]

@@Shaker-Hamdi absolutely, and thanks for the input!

[@robonkenhout7965]

Not boring at all!! I could watch this all day long. When you were looking for the faulty part and you were (using the clip) and shorting things to ground, but there was no power applied. Could you explain what you were doing a little?

[@macbookfixer]

@@robonkenhout7965 there was power being applied but through my bench power supply, it was 1V at 2A, that’s why the cap got hot! The logic behind that is exactly that, to inject power at a shorted power rail, not higher than the most sensitive component in that circuit can feed off and see what gets hot.

[@robonkenhout7965]

@@macbookfixer Ok, I see. I like the thermal camera method. Just curious how often the component that is getting hot is the actual faulty part? Most of the time?

[@macbookfixer]

@ there is no simple answer to that. If it’s a cap than most likely it’s the cap. If it’s an IC it might be some corrosion under it especially if it’s a bga one, the ones that have solder balls to be placed on the motherboard, or the ic itself might have gone bad or even something further the power rail might be shorted and because the it cannot output the voltage it is supposed to it gets hot. I know it’s not a simple answer.

[@pldaniels]

Good job - a shame though it's an A1708, sadly they've started to join the line with A2179, A1932, A1534 in sad sad CPU failures over time :( At least they have removable storage.

[@macbookfixer]

@@pldaniels First of all it’s an honor having you in the comment section in a video of mine! Secondly The A1932 had it coming and I know you saw that since day one, A2179 and A1708 were indeed a mess.

[@plexi-k3d]

Good repair video! Thanks for sharing.

[@macbookfixer]

Thanks for watching!

[@ΕΥΡΩΠΗΑΜΑΝΑΤΙΔΟΥ]

Your work is really precious! Thank you for sharing your knowledge!❤

[@macbookfixer]

Thank you so much!

[@kencoxdesign]

You make that look so easy and I know it is NOT. My only concern would be WHY that cap shorted and whether that was a symptom of a bigger root issue or just a random bit of bad luck. Working in IT has made me so paranoid and pessimistic when the fix seems simple ;-)

[@macbookfixer]

@@kencoxdesign Every component nowadays has a specific lifespan. Simply put, that cap reached the end of its own. Things are built to break.. although, users might have something to do with it. Knock off chargers, never shutting down their laptop, overheating constantly, you name it!

[@thisisbullcrap9630]

Very cool video. I have a weird question, how do you know where to put power? There's so many components, how do you know which one to give power to?

[@macbookfixer]

@@thisisbullcrap9630 you use the multimeter as I did to determine where there is a short. If you find a power rail that’s shorted, that is your hint. You start from there.

[@thisisbullcrap9630]

@@macbookfixer I see. So wherever there is a short, you just give power to the power rail.. Just learned something new. BTW you have a new follower :)

[@george_annanidas]

Perhaps the best MacBook fixer!! 🤩

[@lordmmx1303]

he and Louis Rossmann.... Rossmann is funnier tho in his videos.

[@Agronomistas]

How about a collab to fix the electronic parts of some tractors and combines?! 😁

[@macbookfixer]

Absolutely!

[@russl3632]

Good video, but how did you determine where to inject voltage?

[@macbookfixer]

@@russl3632 you inject voltage at the point you find the short. And you go as high as 0.9-1V that in case a mosfet that might be shorted won’t pass any voltage to the cpu and damage it.

[@Subgunman]

There is a rest procedure one must try first which involves holding several keys and pressing the power button. Not sure of which keys. Usually brings back these laptops.

[@macbookfixer]

@@Subgunman that works for the later models, and these kind of faults are pretty common in these models.

[@Subgunman]

@ understood. I have a vintage Toshiba Techra 520 series just waiting to be fixed. First I need the HD out to see if the data is recoverable, sounds like a head that will not retract into it’s parked position. If that can be recovered on to replacing the power supply/ processor board with an old stock board. One might ask why? Well as a FCC licensed radio tech I have a ton of two way radio programming software on that drive and most legacy radios from Motorola only program from a slow machine that can boot from DOS.

[@macbookfixer]

@ sounds like a very interesting project!

[@chanthetechman]

Where do you sell these?

[@macbookfixer]

Haven’t gotten to that yet.

[@FuchsHorst]

Impressive speed 👏

[@macbookfixer]

@@FuchsHorst thank you! It happens once in every blue moon! ;)

[@RyRch]

Great work but you need a closer / macro camera, these videos way too boring to watch like this.

[@macbookfixer]

@@RyRch I could have used the microscope one I guess and I am also working on a new setup to be honest. I also am new to the whole content creating thing. It was just an effort to showcase my work in a video and hopefully be helpful to somebody else. Open to recommendations on gear if you have any.

[@SURGE101]

Is the T2 chip on all MacBook models the same chip, Can I replace the t2 from the A2141 using one from another model of MacBook board?Thanks, great watch as always.

[@macbookfixer]

No it is not! It is paired to a specific logic board with a specific configuration. You can swap the t2 from an A2141 to another A2141 but it needs to be the same configuration and of course it needs to be iCloud unlocked.

[@SURGE101]

@ knew you was the right person to ask, thanks so much for helping me with this. Really appreciate it. Thanks so much and merry Christmas and have a nice new year.

[@macbookfixer]

Glad I could help. I’m planning on making a video on power sequences of the type c MacBooks and the thought process I follow to solving various faults. I think you will find that interesting. And we can also discuss what parts are interchangeable and can be used from different boards and what needs to be from an identical donor.

[@SURGE101]

@ that be right up my street, definitely look forward to watching that one, love the channel and content. Really do enjoy watching. Thanks so much rich

[@WinrichNaujoks]

But what do you do when you then discovered that the laptop is linked to someone's iCloud and locked?

[@macbookfixer]

@@WinrichNaujoks you ask the seller to unlock it! If they don’t or won’t or can’t then pretty much the laptop is going to be used for parts.

[@DraconianError]

Pro bro. Happy Holidays

[@macbookfixer]

Happy holidays!

[@liviuq]

Why do you freeze the capacitor?

[@macbookfixer]

@@liviuq It is a different approach to the thermal imaging. You freeze it so when you inject voltage it heats up and melts the ice around it so you can find the shorted component easier!

[@the_grand_tourer]

All that potential e-waste saved because of that one tiny tiny part ! crazy, great job ... pays to have the tools though. £150-£180 on Ebay in UK.

[@macbookfixer]

That is a big discussion brother! At least 90% of electronics can be reused one way or another, and hopefully it will be at some point in the future! Price is accurate though more or less.

[@camdaman813]

@@macbookfixer Not boring at all but I like your response to them. Keep up the great work you're doing.

[@ΕΥΡΩΠΗΑΜΑΝΑΤΙΔΟΥ]

Is it worth doing the same thing with a windows laptop ?🤔

[@macbookfixer]

It depends on the laptop, its condition and the fault of course, but generally if you can find something for a good price and can fix it with your time and effort and a little bit of money I’m sure windows laptops can be profitable as well!
