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).

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

Just fixed one of these for a friend. I found a small brown cap was short. But it would still not start. Checked battery voltage and was around 7.6V I charged it to 8V on a benchtop supply. But it still wouldn't start. tried smc and pram reset. (Left it overnight on it's new fake power brick to keep charging). Next day and it started but in the password screen it seemed to shut itself down once. Asked owner for password and ran a few tasks such as 1st aid in disk util. then a pram reset. Seems ok now. SSD is hot and processor heatsink is hot. Not sure how normal that is. One thing I find strange and annoying not owning a pc is that Paul Daniels board view only seems to work on a pc and not on mac....... One thing I find strange is that the power brick he bought for it recently states an output voltage of 14.85V but the psu for my Retina which has the same type of magsafe has a rated output of 16.5V Wondering if the recently purchased power brick is the culprit? Also. just checked SSD and processor again after the resets and first aid and they are not as hot, much cooler in comparison. Oh well. Lets see if it keeps running and i will double check the suspect power brick.

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!

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?

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.

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.

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.

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.

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?

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?
@AndrewPaul7 жыл бұрын
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

where to buy this component?
@AndrewPaul7 жыл бұрын
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?

@AndrewPaul4 жыл бұрын
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?

@AndrewPaul5 жыл бұрын
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.

Hi, do you have pay help option? I have 0.9v on F7140 and L7130 and all ppbus_g3h shows 0.93v
@AndrewPaul7 жыл бұрын
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?
@AndrewPaul7 жыл бұрын
Do it with Pin 2 also - don't know where that bit disappeared to in my last message lol!

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).
@atinder20067 жыл бұрын
Andrew Paul L7130 removed pin 1 shows 14.99. will check those ones later. And thank you so much for your help
