Logical, concise troubleshooting. Better than excellent component replacement skills. You're a rock star, dude! 😎👍

[@massimobazzano1233]

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.

[@mohammednadeemuddin9133]

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,

[@tomb8430]

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.

[@huaweihuawei-gy8ix]

You explain well keep making videos so people like learn from the master😀

[@gkmq6411]

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?.

[@SleazyNice]

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.

[@PowerbookMedic]

Yes, that was a mistake. There have been some comments on that already.

[@royalairsoft2866]

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.

[@spangles3654]

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?

[@harhar4607]

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?

[@PowerbookMedic]

Yes, it is diode mode.

[@Hari-lynx]

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

[@jeffcole5708]

Nice repair. Would you say an ultrasonic clean could have fixed it or made it harder to find ?

[@PowerbookMedic]

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.

[@jeffcole5708]

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.

[@roontunes]

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

[@PowerbookMedic]

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!

[@roontunes]

thanks

[@milthonurregozipa1683]

Thanks for your teach, but i need to know how many is the value of condense (C6405) in nanofarads o picofarads, from Bogotá - Colombia.

[@fleminggustavo]

Hello brother, it's possible you let me know the name to that schematic diagram program please

[@chato_bajo666]

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?

[@Kevin-nw9om]

What do you use to get the boardview?

[@shariffabas]

Nice work

[@chrisnaser3782]

Cool video! I see the drum head with the paint on it, any chance it is from the BLUE MAN GROUP?

[@peringotan5769]

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.

[@mysterilv7132]

Good day.. sir. may i ask a favor regarding the board view what software you use? please. let me know.. thanks

[@Bama_Law]

RTR BABY!

[@vp2777]

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.

[@dicernir]

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

[@linksrepair2851]

another great video and good explaination,thanks for your ideas man

[@applediamondz6157]

what temperature was the heat gun to remove the broken transistor

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

[@jeff666p]

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]

Same here

[@kharovevo6485]

Did u fix yours?

[@jeff666p]

@@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.

[@kharovevo6485]

U mean u changed the motherboard

[@juanrivera4938]

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!

[@PowerbookMedic]

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.

[@juanrivera4938]

@@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

thanks! i solved the same fault with your video, thankd for share!

[@aarubs]

What software are you using to identify the components? Could you share the Mac Book libraries if any?

[@PowerbookMedic]

aarubs I use Open Board software and there are many different companies that sell the files. If you just do an internet search for them, you should be able to find them easily.

[@MrPnew1]

Open Board View (free) and Flex Board View (paid) are both available here pldaniels.com/ You can find board files and PDF's on www.badcaps.net/forum/ and here www.apple-schematic.se/board-ids/

[@JonnyMagwood]

At 14.45 you test a component for a short. When I have my MagSafe charger connected to my MacBook this component reads as a short but when I have my battery only i don’t have a short? Any advice anyone?

[@JonnyMagwood]

Note, I’m talking about the same component.

[@JuanDiazSilvermyst]

What program do you use to keep the Schematics organized?

[@PowerbookMedic]

Juan Diaz I just have them separated into individual files on my computer.

Please I need help my macbook pro mid 2012 A1278 was working fine and left to come back and I found is blanked out dark try several things to power it on but avail, I remove memory, try to plug direct and power on fan will roll a little bit and stop and the indicator light will blink and it won't power on anymore though my battery status before it's happened says replace soon. Can that be battery? If yes but it's dosn't on without battery when I plugged in direct. Pls any solution

[@PowerbookMedic]

Jaaiz It sounds like a logic board problem, but it could be multiple different components. I couldn’t say for sure without diagnosing it in shop.

[@jamiusamin]

@@PowerbookMedic but if I check the battery status from the left button it will show the green light if I plugin charger it will be charging but not turning on

[@brianmpundu7966]

Powerbook Medic yes I’ve done that and still nothing is happening

help! hi my name is David i have a macbook pro a1278 no power in it i need help!

[@PowerbookMedic]

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
