This video shows the diagnosis and repair of a mid-2013 Macbook Air computer with an 820-3437-B motherboard.
This particular machine has some issues with its PPBUS_G3Hot power rail - it should be 8.6v and it's actually measuring just over 1v.
Here we take a look at the schematic, board view and find the problem, replace the faulty component and get the machine back up and running once more.
Unfortunately I cannot share these documents or link you to them but a search on Google will return them without too much aggravation. Any part of these documents used within this video are intended to facilitate the repair of the faulty equipment shown and for no further purpose.
Many thanks for watching and please remember to comment, rate and subscribe for more videos.
I hope to have more Macbook videos up on a regular basis going forwards - fingers crossed as I do enjoy working on them. - Jak na to + styl
I'm an old guy but still spend loads of time on the YT learning lots of ways to save money. This cat is good. I got this!!!!
Just fixed my old 2008 macbook! Wasn't the same issue but Openboardview and your video was all I needed!
THIS IS GOT TO BE THE BEST AND EASIEST VIDEO TO FOLLOW ON CZcams TO LEARN HOW TO TROUBLESHOOT BOARDS AND LEARN BOARD REPAIR. HE EXPLAINS IT SO WELL AND SO EASY TO FOLLOW. JUST SUBSCRIBED. ALL THE OTHER VIDEOS ON CZcams ARE HARD TO FOLLOW BECAUSE THEY ASSUME YOU SHOULD ALREADY KNOW WHAT THEY ARE TALKING ABOUT AND THEY ARE VERY HARD TO FOLLOW. JAY
I dont have a mackbook but paul helped me figure out how to take apart an xbox one. He is a great help!
Bob Thebuilder how did you contact him?
Just watched the ps4 repair from hell and was going to ask if you had ever seen Louis's channel. Then i saw you were subscribed so I jumped ahead to this Macbook repair. I've learned so much about repairing Apple products from him that they are most times easy! Can't drag solder as well as him but I just try blaming that on not having as nice a scope!
Indeed, Louis is something else - love his work and what he does for the YT community.
Great video Paul!
This video was indeed of help. Replaced a blown cap and was getting this same voltage reading on the power rail. Changed the same fuse on mine and boom💥 its 100% working.
Nicely repair. Well done. Its nice to see some different stuff being repaired on your channel.
Cheers mate - yes I'm trying to diversify my content a little - I'm getting into Macbook repairs recently so hopefully there'll be some more interesting component level stuff to come.
I have a load of dead macs and laptops I get given them for part as I help out my local recycle centre I didn't realise you repair them as well, I have an a1466 that doesnt even show the charge light
my ps4 is still going strong cant thank you enough for fixing it =)
Yeah Macs are another of my babies ha ha! :)
If it's not showing the charge light then it's missing the One Wire circuit - check PP3v42 is present along with voltage to and from the logic gate. If that's OK then you're best replacing the ISL6259 (U7100).
Learn so much more from you than Louis.
Good job! Thank you!
Thx buddy, very simply explained
Amazing,, extremely talented, wish I could be smart as you
Thankyou so much from Adelaide Australia. Been in electronics many years but always need help with familiarisation of particular systems like the A1466 you have been very very helpful, so thanks again regards Trev
Cheers Trev :)
Just wondering if you can tell me what program you use to open the viewboard type file "brd" regards Trev
It's OpenBoardView - a superb, free piece of software.
openboardview.org/
You are a legend thankyou so much I have it set up. Just need to fix my Granddaughter's A1466 13inch 2014 now which had water on keybrd now dead all round absolutely nothing have stripped down to just brd so now, as I have both Apple Diagram's plus Board layout, hopefully I can find problem or problems!! haha Regards and thanks again Trev from Adelaide
No problem mate. Best place to start is the Power Aliases page - measure each voltage rail and check it matches what's in the schematic. Note any that are missing or off what they should be then go from there :)
Andrew, Thank you for the video.
Can you please make a video for with the same method explanation for DJJaaM question.?
I have the same problem (A1466 2013) after liquid, It seems a common problem.
I don't have the schematic but I checked the Fuse and I have PPBUS_G3Hot power rail - in my case its around 8.1V.'
I have also 3.3V which going to the battery and to On Switch
Its wonderful to see. It was really helpful. Thank you.
U save my life ❤
Great Video Andrew. Congrats for the excellent job. I was wondering if you could help me with my MacBook air a1465 that stopped to work suddenly. No liquid spill. I have no green light and no PPBUS_G3H and the fuse and coil are OK. Which are other common faults in this kind of board? Thanks.
Thanks man
Hello, I'm from Brazil and I was able to find your video after a lot of searching on the internet, I work at the company AppleVale, here in Brazil, we only work with Apple products, your video helped me clean 3 plates this week. Thank you and won + 1 more follower
www.applevale.com.br
thank you verry much
if i have 1.5volt on 1st pin F7140 what i need to check? thank you for video!
brilliant fault finding m8
Cheers mate.
Do u really need to take out d board when i want to chk voltages? would it be ok to just have it stay there and uae multimeter? im suspecting i also have fuse problem. pls enlighten. thanks. wil it damage anything if i dont remove the io board etc?
Hi thank you for this video. I have the same issue on a Macbook A1465 11" 2015 can you tell me what is the reference of the fuse for this model ? thank you !
Thanks for the help. But I'm stuck on figuring out how to purchase those parts? Currently I have a 820-00165 with a dead F7140 and C7374. But I have no clue how to find out the correct size and values of the part to order. I tried mouser and entered the values for the tant-poly cap but they are no where matching to the needed stats (65uF; 20%, 11V; CASE-B2S). I can't find any cap that suits into all of those values. How to pick the correct one by adjusting a value? Also for the fuse. I basicly only have 8A/24V but nothing else.
Can you give me a hint on how to find out the correct spare part? Thanks in advance
Great job exactly the same problem on one of my macbook air and thats it you save my day^^thanks
Very easy to follow. Liked and sub'd. Thanks Andrew!
Thank you :-)
That is a great video. My macbook is the exact same model and I am unable to power up. I get the correct voltage up to that circuit you replaced but still not power.. Any ideas what can continue causing issues? Any help will be appreciated
ive checked for Voltage at the fuse, getting 8.6V fine. is there a list of possible components for no power, with required nodes and voltage measurements to ground? my battery replacement did not fix it. the device said service battery for a few months, and the customer didnt bring it in until after the device shut down
Mines doing the same thing I checked that fuse it's good on both side but the power button still don't work if you unhook the battery then hook the charger up it boots fine. I've also changed the keyboard and the controller on the back side of the mouse. Where else could I look? Thanks
I have a question what liquid did u use to remove and clean the component that you replaced? Where can i get the replacement component? What is the name of the component?
well working
What temperature are you using on the hot air gun?
Love ur videos!!! Here's a question for the infrared red that I want to fix but am almost afraid to try as I know virtually nothing about hardware.... After a drop my MacBook Air began behaving really odd (surprise!) no sound or audio is the only constant. Sometimes it won't turn on unless I do the... er, command, option, tab, power... thing lol ugh (embarrassing I'm SO SORRY FOR MY TECHNICAL 🙊🙈TERMINOLOGY🙈 🙈🙈😶)
Lately tho I can turn it on without having to do the usual (for me) which was: mess with the charger (plug in take out at random while I knock on the bottom of it and down it's spine , press the above keys & repeat til it worked.🙊🤔👍
It's coming on now without that but it's done this before only to return to the above again.
Also I get the black "screen of death" a lot, and program crashes where before I had none of that. So now really it's just my sound/audio... sometimes the battery will get very hot but usually it's the standard apple "cool/feel nothing going on"... 😐🙊 ahem so! 🙈 should I open it up to fix? Or is there a way I may can reset it & fix this without the need of risking me -a clumsy person- being a surgeon with my MacBook🙊🙏 ? I did a "factory reset" and nada happened .... that is needless to say to u guys I'm sure tho lol sorry.. hope to hear soon!!! Either way keep making your videos, absolutely awesome!
i have the macbook Air 13 2017, will this work on it?
Hi Andrew- Any idea what caused the fuse to blow? I usually find the fuse blows for a reason like a faulty charger but almost never without a cause.
I’ve bought a macbook air 2012 that didn’t start at all, but the charging plug was lighting up green when plugged in and amber after few seconds. My fix was in freeing the motherboard from all wires and then reconnecting them(without the battery), put the back plate back on without the screws, then opening the mac, plugging the power cord and it started up, then safely turned it off and installed the battery and that was it. Worked on 2 Macs so far
I have a no power issue on the same board, and I’m getting 8.18 on both sides of inductor and both sides of the fuse. Any thoughts?
Thank you!!!
Edit: there is also no visible damage anywhere, however I was told a ridiculously small amount of water fell on the corner of the keyboard. Worked fine put it to sleep and next morning not powering on.
Thanks for that - I tried all the resetting procedures, but nothing worked. I thought the laptop may have been dropped or most likely a SMD fuse, but wasn't sure what package the fuse came in. After seeing you video clip I immediately identified the fuse and lo and behold - open circuit! However, just wondering why you removed the PCB from the laptop, as you could have done this repair without removing the PCB. Thanks anyway, I did it for my neighbour and she'll be very, very grateful...LOL!
hi can u give me details this part which u replace mate? i have to buy as well mate
Has anyone ever been able to find this F7140 fuse for sale? I don't have a donor board but i've tried a couple of different types of 8A 24V 1206 surface mount fuses and they don't seem to work. When the fuse is off the board I get 8.5v on pin 1, then when I put any of these fuses on pin 1 drops to around 0.5v. Am I missing something? Am I wrong in assuming these other fuses should work?
Genial
super /........

Cheers mate.
One Question- when you used the multimeter to test the "PPBUS_G3Hot" -where did you put the black lead of the multimeter? I know you said "ground" but what would be a good ground to use? I was able to open mine up and put red lead of the multimeter but it was showing negative voltage (like -7 and or -8).
Black lead on any screw hole or find a GND pin on the boardview. Red lead on the pin to measure in DC volts mode - if you're getting somewhere close to ~8.6v you're good.
Hi Andrew, mac air 2009 - wont power up SMC resets didn't work, took back off - processor ? is red hot (big multi pin ic next to charger connection) model has huge battery covers about half the inside of the machine, model to small to read off rear of machine at 1am.
+MrJTJINX any lights on charger at all when connected?
Hello! Very good video! Where you buy the components?
Hey man, I have a macbook 820-3437 and the PPBUS-G3Hot power rail checks back at 8.5V. What is your go to after that? I cant find any traces that look damaged. It was originally water damaged (beer damage). I can't figure it out. If you could shed any light that would be great man. Thanks.
PPBUS_G3H is just one of the required rails you need. Look around the board for any dried liquid stains and red probe points etc for pointers as to where the damage might lie. You'll need to ensure you also have other required rails such as PP3v42_G3H, PPBUS_S5_HS, PP5v, PP3v3, PPVRTC_G3H, PP1v8, PP1v5, PP1v2, PP1v05, CPU VCORE etc. Look on the power aliases page (p62 on that particular schematic) and check each listed rail - see what you have and what's missing then go from there.
Very enjoyable, had to pay even more attention to the Englishmen
Hey man, can you tell me where i can buy the inductor that you changed? I found a faulty one on my A1466 Macbook Air but i don't know where to buy it? Amazing video by the way
Hi, yesterday I wrote to thank you for your clip on the open circuit SMD fuse. I ordered a pack of these this morning, but then decided to measure the SMD fuse to confirm it was O/C. Strangely, it reads .4ohms, which indicates it is still intact, though there is only 8.6 Volts on one side of the fuse. Further investigation shows that a number of SMD caps (some in parallel) next to the fuse read S/C, probably sucking the 8.6 volts on one side of the fuse, to ground. Most likely just one of the caps is S/C. This is all I can think of. Have you any ideas?
Andrew Paul is their a better way to talk to you I have the logic board I think it just has slightly different parts/locations and I am bad at this kid of tech and the symptoms are must be plugged in to use but if unplug before shutdown screen go black but mouse is on it and it can be moved
Great video, Luis will be proud ;)
Ha ha! Cheers mate :-)
Who the hell is Luis??
PPBUS_G3Hot, is created inside of the circuit or in the mosfet and coil ??
Bonjour merci pour la vidéo. Je ne trouve pas les neo condensteur tokin auriez vous un site ? Merci d’avance.
Durga Mahapatra
Nice video and explanation. I have a mac air 13 2012 which is dead. From the 5V rails PP5V_s0,S3 and S5 are missing. Can you pl tell me where to look for problem ? Thank you so much
any link to buy this fuse???
do you use donor boards or order parts new, if so where do you order components
A bit of both - some components are programmed and cannot be manipulated outside of official channels (i.e. SMC) so these are lifted from donors, as are many of the smaller SMDs. Common items such as LCD connectors, fuses, backlight drivers, charge controllers, C9560 / C7771 etc are all new parts from electronics distributors like Mouser, Farnell etc.
Ross for President!!!! :)
Can you replace the charging port ? If so where can I find a charging port ? Would I need to solder ?
Yes you can - it's a harness which plugs into a socket on the board so it's an easy change.
hi Andrew , I have a Macbook pro 2011 a1297 ( 820-2914) , it charges the battery but only would start up if I disconnect the battery and connect it back in. Would you give me some clues as to what to check? thank you for the very Informative video
I have a similar problem with a A1466. It will only start when the battery is disconnected and yes I have changed the battery.
John Mathias hi John, after investigating , the problem was with the keyboard. the power button is part of the keyboard circuit and it wasnt shorting when pressed. For some reason it works when the battery is disconnected -something in the circuit logic. hope this helps.
plz sand me macbook air a1466 schematic diagram same laptop
..... adaptor light not glonw also a no power problam.
Hi,
Sadly I can't do that as they're not freely distributed however I will say that Google is your friend here. It's likely you're missing either PP3v42 or PPBUS_G3H if you have no power/no light on charger.
paul can u.make one video on how to read and use board view and laptop schematic plzzzz
I'll see what I can do :-)
Question how do you tell if the ram is bad and the ssd
Where can I find this fuse?
Awesome information!! Andrew, i have one A1466 that is similarly dead but in my case, neither the charger light turns on, tried with another charger but nothing, where can i begin testing to see the problem???
You'll need to check for PP3v42_G3H to see it's present at 3.42v - you'll need to check the Onewire circuit firstly to ensure you have the necessary signals going to the charger control IC. What motherboard revision do you have there? Should start 820.
Andrew Paul thanks for your reply, the revision is 820-3437-B
following this since I have the same problem with a 820-3024
Andrew, Thank you for the video.
Can you please make a video for with the same method explanation for DJJaaM question.?
I have the same problem (A1466 2013) after liquid, It seems a common problem.
I don't have the schematic but I checked the Fuse and I have PPBUS_G3Hot power rail - in my case its around 8.1V.
Thanks for your replies, actually the computer now turns on/off and charges after i checked with schematics. But now there's another problem... No power on all PCI-X so the computer won't recgnize the SSD and WiFi/Bluetooh Card...
What is the open press down type connector that is near the middle mounting hole on the motherboard? I ask because the Mac mini 2014 has a similar connection that is apparently a way to connect to the PCIe bus. ( beetstech.com/product/ssd-cable-connector-821-00010-a )
Would it by chance be possible that the 2012 MBA has that same connector and could it maybe be used for a NVMe PCIe Drive with maybe an longer flex cable?
What characteristics is the fuse? thank´s and pleasee
8A / 24v. 1206 package.
Halo Andrew . Thank you for your video. I know this is from 2016 but if you still hate Adobe PDF use Sumatra PDF instead much, much better....
Sir in some cases after replacing the fuse it blows again. What could be the reason
Lift the coil behind the fuse and check for shorts to ground on either side. Hopefully it'll be charger side as it'll be a lot easier to diagnose. If it's system side then you'll need to hook the system side of the coil up to an external power supply and feed in voltage/current to see what gets hot first.
the ppbus_g3hot passed on both sides now what to do if ppbus_g3hot passes
After removing the fuse you do not measure if there is a short to ground. Why else should the fuse blow? is that not a miss on your part when fixing this?. That again can make it fail again. Have done rep on electronic few decades. maybe i missed you checked that. Keep on doing board rep, Great to see.
Hi, It was in the video at some stage - someone shorted the rail when messing with the WiFi card antenna cables.
i get 8.4v is that normal ?
Hello Can I send you my mac book air 2013 for fixing please? It will not turn on. I have done all the usual tricks and have even tried to cross the power-on pads location on MacBook Air - A1466 but still not good. I have replaced the battery and it charges. Regards Jay
+Jay Chapman Hi Jay, drop me a message at ytandrewpaul@outlook.com and we can discuss it further. Cheers mate.
Hi i have a1466 No power I Removed batterry and tried also tried to remove ssd abd ram as well no luck.
When I tried to reset smc its turn green for 2 sec and turn orange again. Any clue.
thanks
+MAX PAIN Hi, if it has no power you'll need to check all voltage rails to see if any are missing and work from there. Where are you located?
Andrew! Superb video. You really showed it step by step. Much appreciated. I have a few boards in need of repair. Do you have a PayPal so I can get advice on repairs? Thx
What issues are you having with them mate?
Andrew Paul Hi Andrew! Mainly liquid damaged maybe it would be easier for me to send them to you for repair?
Hi Ant,
Yes mate you can do - do you have anywhere I can contact you on?
Failing that you can contact me either via a message on here, DM on Twitter (@YTAndrewPaul) or ebay:
www.ebay.co.uk/usr/lufcfan2004
Cheers mate,
Andy.
Good afternoon, in Mexico will you know where I can buy the replacement part? and with what part number can I ask for it?
Indeed - if you have the schematic for the board, the component type, size, specification and tolerances are given on the document - just type it into Google and you'll likely get results from electronics distributors like Mouser, Farnell, RS. Element14 etc.
@@AndrewPaul Good day, first of all I congratulate you on your channel. I have a doubt, in my case I connect the charger and I have a green light. However, the equipment does not turn on. The heatsink only rotates a few seconds when I press the power button. Now make capacitor continuity measurements (F7140) and the result is zero. Do you think that changing the F7140 capacitor could be the solution?
do you do mail in jobs on macbooks? i got a faulty 2012 15" macbook pro thats completely dead
Where are you located my friend? Many thanks.
Andrew Paul up in scotland
Sure thing. Do you use anything like eBay at all? If so, drop me a message / phone number etc on there and I can send you some more info. My page can be found here:
www.ebay.co.uk/usr/lufcfan2004
Andrew Paul will do ill message you on there tonight
Hello I have Apple problems same can yo tell me where are you. I want you fix my Mack book 13 is well thanks.
Just realized my board is slightly different can you help I really want this Mac working
Which board is it and what symptoms does it show?
My Laptop MacBook air power on no display plz help
I accidentally touched two components together and it sparked and smoked then I reassemble it and it worked
Blew the short out of the board then :-)
I'd be tempted to run an ASD and see what that pulls back then go from there.
what type of fuse is? thanks
8A, 24v 1206-type.
Thanks for the great video! I got 2,5v at that inductor and the same at the fuse..anyway i don't have light on the charter but It feeds normally about 15v.. thanks for any advice!
Remove the fuse and see if you have the correct voltage on one side of where the resistor sits. If you do, you have a short system-side which is pulling the voltage down. If not, you likely have a short on the supply side pulling the voltage down. Squirt the correct voltage in under a decent amperage with a bench power supply and have a feel around the board / use some IPA / Freeze spray etc to see if anything is getting toasty then if you do find something, remove it and see if the voltage then returns to its normal level. If so, replace the affected component and hopefully it should work OK.
@@AndrewPaul thanks a lot!!
do u do repairs to these?
Hi, yes we do - contact us at ytandrewpaul@outlook.com.
Hey please see this can you suggest a link to the fuse.
It's an 8A, 24v 1206 metric fuse.
Anywhere like Digikey, RS, Farnell, Element14 etc will have them.
Andrew Paul Thanks
Where do you get the components from
Macbooks - depends really. Some of the major ICs like ISL6259s etc are easily and cheaply purchased new from most component retailers. Things like SMCs and small surface-mounts are taken from donor boards.
pleaserecorde some vedio how to use scematic to locate componient
Hi Majeed,
Sure - are you needing help to identify where these things from the schematics are on the board itself, or to find replacement components online to purchase after finding them on the schematics etc?
Bro where to download MacBook schematic ?
google it
Hello, where can i purchase the F7140 fuse? thank you
A1466 model
where to buy this component?
Anywhere like Mouser, DigiKey, Farnell, Element14 etc will have these in stock. Be sure it's definitely the fuse though - they aren't often the cause of a missing PPBUS_G3H line unless you're aware of some tinkering in that area of the board as in this scenario where someone has shorted the component directly. Do you have light on your charger when connected?
Hello you could send to my mail the link where I can download the electronic diagrams, thank you very much for your help.
Sadly not mate. All I can tell you is Google is your friend on this one.
Full scan says pc good
Excellent - should be good to go then :)
What is asd
Apple Service Diagnostics.
hi i got a macbook air my kid splil water on keyboard now is death can you advice me problem
You'll need to remove the motherboard and see what damage has been done beneath.
It won't likely be an easy fix - if you're not used to this kind of work then it might be best to take it to a professional.
Thanx Andrew
Hello, please can I bypass that ?
Never be tempted to bypass a fuse. They blow for a reason and failing to fix and identify that reason may lead to further permanent damage down the line.
I like louis too... question is...why did the fuse blow ?
Love the guy ha ha! This one below the fuse as the previous tech managed to short the rail whilst removing the WiFi antennas during an attempt to reseat the card. Clumsy.
Who the hell is louis? Louis Rossmann? He sucks! Paul is great. :)
Dear Paul I have the same problem this Fuse in my Macbook Air mid 2015 . What means the description 8AMP-24V in the Macbook schematic? >>> Current Rating: 8 A and Voltage Rating DC: 24 VDC or is the Interrupt Rating: 8 A . What kind is this fuse ? Fast, normal or slow switch off?
Hi Tim,
Yes this is the fuse rating - fast blow IIRC.
Could be this the right Fuse? Littelfuse 1206SFF800F/24-2
www.mouser.de/ProductDetail/Littelfuse/1206SFF800F-24-2/?qs=sGAEpiMZZMtxU2g%2F1juGqVOiOI%2FX23Q%252bGM2vLF4aVZQ%3D
Looks good to me.
Thank you :-)
You can't have watched Louis very carefully- that was nowhere near the approved amount of flux 😝
Ha ha! ;-)
Louis SUCKS!
Hi, do you have pay help option? I have 0.9v on F7140 and L7130 and all ppbus_g3h shows 0.93v
Are you getting any lights on the charger? Sounds like something is pulling it down. Remove L7130 and measure the voltage on the motherboard at pin 1 - do you still get 0.9v? What meter reading do you get in diode mode, red pin on ground and black pin on pin 1 where L7130 should be with it removed?
Do it with Pin 2 also - don't know where that bit disappeared to in my last message lol!
Andrew Paul no light, no fan
Ah ha! That could well be it then. Do you have a known-working DC-in board there to test?
If so and it's good, at Pin 2 of L7095 do you have PP3V42_G3H showing up? (approx. 3.42v).
Andrew Paul L7130 removed pin 1 shows 14.99. will check those ones later. And thank you so much for your help
