Very well done video, clear explanations, views and tech knowledge. I wish I could get that board view feature to locate components on the board. Thanks.
To Be Honest, It was a great Service experience, it was my first Apple laptop to service with your help i was able to resolve it, millions of thanks sir,
Excellent video... and explanation. I got a short somewhere else on my board... I had the macbook in storage for a while, and to my annoyance it would not boot up anymore. When I plug the magsafe in, I get a green light, but battery will not charge, no spinning fan. The area near the 4 square silver pads next to the fan gets extremely hot. The short most be somewhere near there.
Hi friend, how could I get the schematic? since in my case the charger does turn on and charge the battery but in no way turns on the motherboard and apparently there are some devices that look bad and are close to the charging center but I don't know what they are
Hello, thank you for the tuto, I will try to do similar testing of the one wire (I seem not to find 3.4v). DO you know where I can find a breviary a lexicon, of the letters used in parts list (for instance what mean PP ) sorry dumb question ! Thank you
My MBP mid 2012 i5 2.5 A1278 works fine when i am on power adaptor without the battery connected. However, when the battery is charged and connected (with and without power adaptor), I get all sorts of issues on the screen - lines, spots, some part of the menu blacked out, sometimes fonts on some part of the screen becoming larger etc.. Authorised service center do not have a clue and they suggested logic board replacement, hoping that the issue will be solved. However the cost of replacement is almost the cost of the macbook. Any pointers you can provide is much appreciated.
First, i must say thanks a million for some of the most outstanding videos. My question to you is, is it possible to source some of these components from a windows laptop, for example the fuse, resistors and caps?.
I have done the capacitor replacement. The only difference now is after few seconds the keyboard backlight comes on. However the display is kind of blank, it’s not super bright but can see it’s on. The caps lock light come on as well. It’s doesn’t load the OS. Why advice please? Thanks.
Hi Great video, very clear enjoyed watching it. I have a question, my 13 inch macbook when i put the power jack in i get a green light and when i switch it on only the fan spins. Any ideas?
Awesome video, def helped me diag this MacBook I've been working on. Is there any way you can share the details on the schematics program you are using? Seems like a super useful tool and I'm highly interested in it.
Hi As usual a truely educational video. Just one question - you refer to using the resistance mode for short detection but I feel sure you are using diode mode, am I correct?
Always look over a board before cleaning it and even take pictures if necessary as where you notice visual damage is the best place to start. If you clean the board first it makes it significantly more difficult to trace down problems.
Thanks for that as sometimes you hear on different posts that the fault clears after a bath, I appreciate the advice as not to miss the opportunity for the fault to show itself.
Im having an intermittent issue. Sometimes it works s=and or times not. Something=imes i have to unplug it for an hr before it it will charge. I bought a new charger from bestbuy and it does the same thing. Is this likely the dc board?
@@kharovevo6485 I don’t know 100 percent yet. After I changed the board I had to go away for 3 months. I got back 2 weeks ago and so far it’s been fine but when I bought the new charger it also worked fine for 2 weeks before having the same thing happen. One difference I noticed with the new adapter is that there is a small delay before the light turns on when connecting the charger to my MacBook. I read this is normal on the old board it always instantly turned on. I don’t know if that means the board definitely had and issue though.
the same on this macbook pro my friend got, a milk spilled on the keyboard and after that no power. i can see a liquid problem on the board just as you did on this video. is it possible if i could hot air the board it will be on ?
Rukshan De Silva We explain temperatures and things in this video. th-cam.com/video/6xzeXBmD3iI/w-d-xo.html And there is a link to all the products we use in the description. Thanks for watching!
that was really interesting, exactly the problem Im having and I do have a donor board but it has the same problem, BUMMER, btw I'm curious how you used hoty air to remove the faulty capac itor, that solder must have a really low melting point
roontunes It is lead free solder, so the melting point is higher. I have just learned where to hold the hot air, at the right distance to not damage the other components. Just lots of practice!
Thanks a lot but my A1278 13 late 2011 get turn on but no CHARGE THE BATERI change the plug in dc and no charge the battery can show me a direction to go thanks so much
Hey there! great videos!! I'veseen tons of your videos but i cant seem to find if you ever told whats the temperature and air speed you use to desolder, i've been trying to remove some QFN and it takes me forever! now im preheating to 200ºC and then puching 400ºC for 20s to remove but still you seem to do it so fast! im using the wider "mouth" of the air machine also, can you help me out? thanks!
We typically use 450 C with almost max air speed. However, all of this can vary depending on the hot air station and the user. So really it’s best if you mess around with different settings yourself until you get the results you are looking for.
@@PowerbookMedic Thats great thank you! i was using a method that a friend told me: 200ºC for 2 min + 360 for 40 seg but it didnt work at all at me. around 400ºC with 80% speed seems to be great, thanks for the tip i wouldnt have tried :D

A no power issue on an A1278 could be any number of things. Try a replacement adapter and if that doesn't work a replacement magsafe board. If the unit still doesn't power on you likely have a board issue. We do have a send-in repair service if you're unable to figure it out on your own: www.powerbookmedic.com/mac-service.php
Great content, very informative but the audio was terrible. You need to stay on mic. I suggest you might get a headset mic, That way you're always close to the mic because you're wearing it.

Hello wanna ask where to get those schematics
Hai bro my macbook pro is A1278 model it's not oning and it's bord is get changed bord hot what I do please tell
What is the name of software motherboard troubleshooting !? I need help for may MacBook pro
You explain well keep making videos so people like learn from the master😀
What do you use to get the boardview?
When you checked for the short to ground - PP3V42_G3H you said you were changing it to Resistance Mode, but you changed it to Diode Mode.
Yes, that was a mistake. There have been some comments on that already.
i checked the first component as you did, but I am getting the 3.48 V in the multimeter still no light or power on macbook pro. Any other suggestions?
Good day.. sir. may i ask a favor regarding the board view what software you use? please. let me know.. thanks

what temperature was the heat gun to remove the broken transistor
Hi
As usual a truely educational video.
Just one question - you refer to using the resistance mode for short detection but I feel sure you are using diode mode, am I correct?
Yes, it is diode mode.
hello sir,what application is this?for OSX version please
Thanks Bro,amazing VIDEO😍😍😍
where can i get that kind of software diagram?
Where we can buy that transitors for fix It?
Great video thanks! Can you tell me the value of C6405 Capacitor? I have the same bad cap but no spare board to get the part from.
I found the capacitor value 10 uf at 6.2v.
Please where do u recommend I get board schematics?.
I have the same board which has green light but no fan spin and doesnt turn on. Not sure how to go with troubleshooting.
Nice repair. Would you say an ultrasonic clean could have fixed it or made it harder to find ?
