PM_PCH_PWROK is not required for PM_SLP_S4_L to come up. But PM_SLP_S4_L is required for PM_PCH_PWROK. The fact that that missing PM_SLP_S4_L was apparently caused by missing PM_PCH_PWROK is most likely because the board was in fact power cycling from PM_SLP_S4_L up to ALL_SYS_PWRGD. The B&K Precision 390A is a bit slow as a multimeter. Chances are it may miss the spike. Especially on 3437/00165, liquid damage causing issue on pin 8 of U1950 is very common and will cause power cycling.
I like how Apple boards are so advanced that they self diagnose with obvious corrosion where the problem is. I have a power supply that I've been trying to fix but it's not advanced enough to identify its fault for me with conveniently placed corrosion.
Hello Louis, I've recently started learning fixing laptops and I'm happy to say I've already fixed around 10 devices, with help from two great, experiences guys. I really love doing this and I just found your google document; excited! I had one quick question though. Can you - for once and for all - answer this question for me? Is it best to always - whenever possible - charge your laptop, even when you're not using it? Is it not good to do this with your phone and preferably use it between 40 and 80% (drainage)? Is it best to always turn off your iMac or never really turn it off? Especially the fact that it seems to differ per device, caught my attention. A quick, short answer would already be really appreciated, but It'd be even cooler to actually understand WHY this is the case. Thank you so much in advance and thank you for your videos.
Schrodinger's logic board, as long as nobody understands the logic of the recursively dependant signals, it'll either mysteriously work or not work at all. Don't mind me, I'm just tired, I haven't slept in ages and this is the sorta crap I come up with.
Really would like to get analysis of that solder.. I will bet, that if it has silver in it...its very low. If you can show its not GOOD silver solder, you will have another point to give to apple..
So you want a sample of the flux to determine the solders content? How does that work? If I send you a sample of the oil from my truck can you let me know how my tread depth looks?
@@--_DJ_-- DJ, metals are easy to sample...And your oil is also.. by the viscosity.. Solder is made from different metals, generally 2-3...and they can be separated...IF you over heat solder, you cant destroy some of its components, and WHy it get hard or soft if not used right. HOW do you think we got Solder and silver in the first place...bet you have never seen 99.99 silver.
Its just that seeing green stuff on the solder is not a great sign of good solder.. Iv opened electronic that have been 30+ years old, Iv seen the insides of Tube sets...The burn out points on the old tube sets Generally were the contact points for the tubes, and Seldom anywhere else.. a metallurgist can do it in a few hours, easy..
Greetings from Germany. I got an A1278/MC374LL/A mid 2010 13 Inch MacBook pro with random Freezes and Crashes to a Messed up Screen or Just a Plain blackscreen From the Nvidia 320m Chip, it only happens when it is cold or not used. It Works fine under hours of full load, but Crashes when its Not doing anything. Ive Seen that the 15 Inch Model with the 330m has Problems with the Caps not Working correctly. I had the Board out and could Not see any liquid Damage. Im visually impaired so its quite Difficult for me to get this properly analyzed. Did you have a similair Thing on one of those and Maybe have any tips for me where i should Start?
My girlfriend has a Macbook that gets really hot in the back area and the internet browsing, and processor response speed gets slow when it heats up. What do you think this could be? I live in Chicago, and am considering bringing my laptop to you since you know your stuff so well.
What MBP model/year?, since when the problem started?, did something happened/changed with the MBP since the problem started?, for me it sounds like thermal throttling, a lot of apple products have poor and almost non existent ventilation and when things get too hot the cpu/gpu start slowing down to protect itself, if thermal throttling is too aggressive it may be the fan or the cpu thermal paste, if not sent it to master Rossmann because something in the internals is F* up.
If it’s a little older the cause can be as simple as the fans being dirty or it could be the thermal paste is past its prime. I am no expert but some canned air and new thermal paste does wonders. This is of course if nothing hardware or software related is wrong with it. I would start with simple stuff first and if that doesn’t work time for a professional.
Louis, my parents have a 10 year old iMac that works perfectly but they just got infected with malware that took down their working computer. Can you fix it?
Was this macBOOK not already death for a long time. I can't believe that the connection was never there or was it? A good soldered connection can not loosen up, and corroding in minutes/hours? Ergo! The board came already with a loose connected (although touching) pin from the factory in China!?
@Louis , I'm learning here and I've got a question regarding U1950. Shouldn't it be sufficient to have a signal (SMC_DELAYED_PWRGD) on pin 6 (and thus pin 5 since they are tied by R1963) resulting in a logic "1" outputting PM_PCH_SYS_PWROK?
serious questions do other tech companies do these deep repairs ? can these repairs be warrentied for a year ? do you think these repairs will be cheaper than what apple does now (in terms of scale and talent training and work hours put in ?)
You ask the macbook why they are broken and bruised? well... let me tell you that these apples don't fall far off from the tree, and veritably hit every branch on the way down
Man, I have Lenovo cheap laptop, the G series of 2013, and to this very day, still works very good with no problem, even the battery still last 4 hours of continuous work, even though the battery already had decreased to 80 % wear percentage. Most repair videos I see in this channel is MacBook air, which is newer than mine
Then you are like the majority of us (I think), most of us have no idea how these work were just here to see a terrible product get repaired by a janitor with a microscope
I replaced the microphone that started dying in the last few videos and putting out static with a new one. amzn.to/2T0ZnGE Let me know how it sounds. Thanks for watching!
Sounds good! Can even hear Paul's chair creak, get that man some oil for those springs! XD
Isn't "Static" your code word for "Sonic Cleaner"
Yikes! That is a super expensive microphone! Can't fault the audio quality, but that price/hardware combo seems extreme for TH-cam streaming.
Sounds perfect
Sounds good
Why do I like watching Louis cure little macbooks
Bob Rossmann is life.
Because its a great feeling to see something broken work again.

how the heck does corosion reach the middle of the board but shows no corrosion in any of the hatches.
The chip had to pee.

@@linuxares this isn't reddit...
whatever the problem is, I hope the PP3V3 is ok
Point on the schematic where the Apple Geniuses hurt you.
My guess is that the "fan spin" is a quick test of S0 state, so you could see signals associated with S0, I could be very wrong though
I like how you speak sir.... I love tech and this is my fav channel to learn thank you L.R.
Damn Lewis, you make it all seem so simple and cool! Keep up the good work!
That iPhone 4 video, I was just watching that out of nostalgia 2 weeks ago!
I want the one with the bigger GBs. Does it have the wifi?
This conical tip is not disgusting, good conical tip
cut less of the video out please, its fun to watch you try to figure things out
You brilliant bastard, Louis.
This logic gates are very complex, but you should get SYS_PWROK_R with only SMC_DELAYED_PWRGD enabled, it's connected with R1963 to pin 5

It could be that it's a mac. They are designed to overheat and throttle because fan noise is such a drag, you see.
@@LA-MJ Well non mac pcs are no exactly notable for being cool machines either.
You're my favorite janitor...
Awe Louis you R special 😁 you feed the kitties
why does apple boards corrode so easily?
Because apple owners are careless
Exactly what I want to know as well, most cheap laptop I've ever bought have a very crappy connector, but the mainboard never corrode
But other motherboards rarely corrode or have these issues even when water damaged.
I Need more flux, Your good though, So insightful = The Bigger The Glob......The Better The Job.
