Hey Louis.. Just a shout out to you to say, "Thank you" for making these informational videos.. They are pretty informational, real and amazing amount of technical stuff in it. Learnt a lot about repairs and fixed a lot of machines just by paying attention to your work over the past few months.. Thanks very much for making these and keep up the good work. :)
I like Louis and his approach on work ethic along with his informative video's. I did not get to meet him at his store in the East Village last week. I dropped off my neice's MacBook Pro for repair. Thank you I'm watching you.
I have no idea how to take advantage of this properly. I make that amazing camera look like crap because the aperture is always super narrow right up against what I'm doing. I've had a few links to basic howto articles for shooting bookmarked, that I've yet to get around to.
Thankyou for the video. I have a macbook air (personal machine) which had water damage, that was sorted with a clean. Ran ok for a year. No visible signs of damage at all. All of a sudden, the machine will not switch on, only the fan spins up to high speed. On battery the high speed lasts a few seconds, on mains it remains on. Any idea at all? I can't find much help on net. I have a schematic, a multimeter, but where to start on logic board?
hi Louis, i have macbook air 11" 2012. the problem is i encountered that my macbook air shutdowns quickly, i tried using it when charging and without charging but same problem. any advice or recommendation? thank you so much.
Hey Louis! I recently F up a thermal compound cleaning routine on the CPU and knocked one of those little capacitors/resistors off the chip. The Macbook pro still powers up and does work but i am worried that something is wrong with my system. My macbook is a MBP mid 2012 A1286 EMC 2556. Can you help me out?
hi, i have the same motherboard , turn on the powersupply light also charge the battery. but not turning on not with the power button niether with the points on motherboard. but when i put the power cable , fan try to turn on. cpu heat up. what you think about this problem?
You speak a lot.. But it's so much interesting what you are doing. I want to know how do you start tracing an issue from the scratch. Also, from where do you the circuit diagrams ? I am an electronics Engg turned software Engg so sort of interested to fix my own stuff by myself.
Hi! Had the same problem with the same Air board. CPUIMVP_TON resistor missing, replaced, repaired the trace, but same symptom. Luckily, i saw on this video that you have one more 0201 resistor, than I have on my board, it was CPU_AXG_SENSE_N or CPU_VCCSENSE_N, I can't recall it now, all that remained after spillage was a little black dot on one of its pads. After replacing everything went fine. The thing that confused me, is that the schematics have components labeled NOSTUFF. Do I think correctly, that these components are never put in their place in mass production of the motherboards? Zsolt
hi sir!! i have macbook pro when i plug adaptor it run fast but if i don't plug adaptor it run very slow could you tell me what is the problem . thanks
hey louis , how are you ? i hope that fine !!! i got here a macbook air with the same motherboard . it came in to our labs , and it was making "beep" noises on startup, so i made a SMC RESET , and it does start displaying image and booting up . , now when its booting , when it arrive to midle point of the boot , it shutdown the machine and its doing this all the time . NOW the weird thing,the client battery is not ok . with another battery it does charge no problem . now even with a new battery and with at least 50% full , once i insert magsafe jack on the computer , it does turn on all the time ALONE, so i cheked and rails seem fine , cheked carefully g3hot lines since one part of the circuit could make a drop voltage or something that would make the machine to shut down , but didnt find any issues . i'm a bit stuck with this one , have you any direction to show me , maybe something i missed . thk in advance , all the best
hey how are you Mr . I have problem with start up and the MacBook work but when I turn on the MacBook pro it's work but the screen become black and after 5 or 6 minutes the screen open . so where is the problem . please can you tell me
hey friend how are you please I need help I have MacBook pro and when I turn on my MacBook pro first it's open white screen then the screen became black for 5 minutes . then the MacBook pro start up after 5 or 6 minutes so I don't know where is the problem . please can you tell me where's the problem
Hi I have a Macbook Air A1369 that after a few minutes turns the screen into a kind of mosaik !! I have tried to bake it in my owen and it worked for a week until it went back to the non useable state. What can be wrong and can the Logicboard be refurbished? It have also had the 3 long beep´s but that´s not an issue anymore after the DIY bake refubish method.
ruba he was beeing sarcastic , the first thing you should chek is if you battery is ok , first of all , second you shnould chek charger circuit , and specialy the parts that are mentioned as CRITICAL on the schematic . usually air , have issues with mosfet (or on dc in or in charger part ! but could also be the ISL fault . chek carefully with schematic , and there are videos from luis showing how to test charger :P
bad explanation bout those 2 fets and whole circuit. actually they work like a push pull configuration , the current gets stored in the inductor when the fets are shorting out, everything is smoothed out by the diode and filtering caps after the inductor...

Thanks!
That blurryness on the camera is called depth of field.
It has a good depth of field

It's called "Depth of field" when everything gets blurry when you zoom in ;)

i want my macbook air i7 and 32GB ram how do i get it?

Worst thing is when mosfet are short,i am also must replace CPU.Also IC may be fry.

Zsolt Palkó NOSTUFF means it is NOT there on the board meaning don't put anything there.

find it yourself.

no because i don't have the machine in front of me, but you do, so you can answer that question
What on earth happened to your Thinkpad Backlight?
***** Spilled 99% alcohol on it.

19:45 for tell us how you replace a capacitor burned and restore the trace with schematic help??,my god...
Hi
I have macbook Air which doesnt boot or run without being plugged to power :(
+Ruba Taha Fix it
how :(
Ruba Taha
If only someone spent 1000 hours of their free time filming a youtube channel dedicated to answering that question for you
Is it that difficult :(
