2012 MacBook Pro Laptop No Power Repair using schematics and circuit board diagram.

[@kalentonggaming7093]

One of my favorite category in repair. Dead unit and step by step checking of power rails before giving conclusion to the device. Keep it up sir, i learn a lot from your videos. Repair Tech from PH.

[@RNMossoro]

is there another page that you follow that explains step by step macbook?

[@blk89gmc]

I soldered my first eeprom for a lcd tv this morning. This was my first venture into replacing an smd component. You sir, make it appear pretty easy. It is not. I need to thank the guy at the local computer repair store near me, for the small tube of no clean flux. It saved my tail after lifting and bridging two pads. Got the pads separated and back where they needed to sit. I learned a hot enough iron(I dont have air) and flux are very important. Your videos are great inspiration to believe I could try. Job done, big smile and on to the next one!

[@harleysofttailtx]

I am just a beginner at micro soldering, and my weakest area is in diagnostics. I've learned a lot from your videos on the usefulness of the visual inspection of components, and loved this one on following the schematics. (I'm sort of glad I don't do Macbook repair!) Thank you for sharing

[@sergeaudenaert]

Some extra kudos to you - unlike some other channels, no foul language here; down to earth and to the point; strong diagnosis; results - thank you for the nice video

[@aquarius9909]

Great repair video. The shorted ISL chip blow the 20 ohm R7005 resistor .

[@Zebra_Paw]

Yep, without diagram this was a no fix! Because you can’t test every single resistor! You can still track the power rail though! Every time I see that good component level repair I feel really good, this should be done everywhere! Absolutely love it 😍 that’s amazing!

[@tonytrilex2555]

I would say out of all your videos I think this is the best one.

[@trilexfix]

I am so glad you answered a question that I have been wondering for a long time about what happens when resistors go bad. I took a lot of notes at iPad rehab and maybe it was covered but that just didn't stick in my head of how they act. I was also making mistakes in my macbook repairs when I didn't check the resistors while the power is one Thank You so much!!!

[@oluwabusayooyegunwa5764]

I've learnt a lot from your videos and also teaching other colleagues too. I always find it intriguing that u rarely use schematics drawings in your diagnostics. Good work!

[@hightttech]

Nice troubleshooting, NF 👍. Many boards are scrapped unnecessarily due to lack of logical troubleshooting. The hackers might correctly replace a dead chip, but fail to troubleshoot, and miss the damaged passives. They give up. Client loses.

[@makingcookingfixing]

Liked and subscribed! Really loved watching the entire video. It's awesome to watch you follow the diagram, read the values and then measure the values on the board. Obviously you have experience, because I would not have known to look for example to the current resistors and that chip. Thanks!

[@automotiveradiator1528]

Would like to see more videos like this...schematics, voltages, and component values.

[@stefcampagna2321]

Very very interesting video with schematics, circuit board and step by step troubleshooting method. Like you use to say : "AWESOME" :-)

[@maxblade01]

As far as I learned from you, I would have changed the chip first then changed after diagnose then outer components... but anyway i am still learning... thank you master flash 🙏

[@calvinmientke3539]

Logical troubleshooting is usually faster than educated guesses. After much experience, educated guesses are fast but still check. It avoids getting confused when you guess incorrectly. If we don't have a stack of doners, guessing gets expensive and time-consuming.

[@georgegonzalez2476]

A little bit concerned that three resistors failed. Resistors don’t usually fail for no reason. Is there some problem on the board that is blowing those resistors? I know you are trying to work quickly but perhaps a little bit too quick?

[@MrJalalalali]

I hate all the Apple's related products but I don't miss any video of yours on repair process.

[@williamwalrus63]

If this repair took you 20 minutes to troubleshoot I salute you 👏.

[@aqib2000]

This is a very common repair to do. Same IC AND same 5 resistors and the twin diode package to check. 5 min diagnosis mate

[@muscleman4799]

The power of schematics is just amazing. I need schematics to fix my laptop.

[@dtrickie]

Hello, what is the name of the software you're using for the board view?

[@YeahNoTellTheTruth]

Love watching your channel, keep up the good work. I just wanted to share a thought about the general topic of your channel. It feels so good to repair things that were complex and looked like they were basically broken. I imagine you get that feeling too? I guess you make some money from these videos, so I can't say it's 'for free', but considering we the viewers do not pay out of our pockets, it's a fair trade with everyone winning here, obviously some more than others (google), but just wanted to appreciate your sharing of expertise.

[@diyfixtool830]

[@PHONE-LAPTOP-REPAIR]

just curious cos I haven't seen or even touch a MacBook motherboard yet. is the chip that you replaced are all the same on every MacBook.

[@mariolemerise7732]

The chip he replaced is a QFN charging IC (ISL6259). You'll find this chip on all Apple portables but it could differ with the portable model.

[@MarkColemanRules]

Brilliant!

[@naptorres4330]

Thanks

[@nikolaoscharalampidis3143]

nice job again! A question: Why you get parts like resistors or caps from donor boards when you know their exact value? Not saying it's wrong, just wondering why. Have a good day! Greetings from Greece!

[@rajawaseem2752]

It’s Usually the quality, value and tolerances are all tightly matched to OEM specifications whereas sometimes new parts from different manufactures aren’t of correct tolerances or values !

[@tinygriffy]

Well it can't be quality since that is a common failure on these boards (ask louis :D), also you can get parts with better specs from any electronics supplier, so I guess it's convenience since they are already there.. on the donor. also you don't have to pay for extra parts. If you want to have a stock of all components that you might need to replace in the future you have to pay a lot of money for that... (having i.e a hundred of each possible cap and resistor you might need, you are quickly in the thousands of dollars ...) I really don't think it's a good idea to solder the same crap back on from another board since these donor board parts are most likely prone to fail like the ones that did in the first place....probably they are close to end of life.... just MO.

[@paolomonai9511]

@@rajawaseem2752 No, this is not entirely true. Basically, one doesn't need a very tight tolerance value in the larger majority of the cases unless of very precise reference voltage value for comparators or regulators. The reason for using donor boards is that you have a perfect corresponding component point to point. So, you do not care of the value of the component, since it is in the same position both on the board to repair and on the donor board. It is a quicker path to solution! Regards from Italy.

[@em0_tion]

Great job 👌

[@mortezaalisarayloo6417]

Hi. Engineer, I had a question. How can I find a schematic of an electronic SMD board on the Internet? For example dvd player marshal portable model ME-118MKII Thank you for replying.

[@lexander9686]

Brother i remember you asking the same question before, usually i type the model number even if it is a Chinese brand, sometimes I get lucky sometimes I don't, good luck

[@lexander9686]

Also some of the schematic like the iPhones can be bought online or you can get a paid subscription, i think

[@lexander9686]

Try paul Daniels software

[@hightttech]

How you enter search criteria in Google will improve chance of finding factory service data. Use keywords like "service manual", "repair", "schematic" and ".pdf" with model number of device (like your DVD player). Check OEM's website for support documents. Look for identifying information printed on the boards and search it; a lot of OEM's use subsections that are readily available from third party manufacturers (e.g. logic boards, power supplies, motor controllers, audio amplifiers and LED drivers). If you cannot find service data, then get pencil and paper and reverse engineer device yourself. GOOD LUCK.

[@GregM]

Due to Apple's litigious one does not post where to download schematics but if you use Google or other search engine you no doubt will get results. Some schematics are hard to find.
