At the beginning of the video he was like "This is a very expensive laptop" and later he was drilling holes in the motherboard searching for one track. Unbelievable. Mr. Sorin is legendary :)
@Tribes11 yep, I read your comment and just about crawped myself, funny shit!! Gotta luv him, and this is TRADE IS somewhat new to me, but I am learning from him!! Thanks a million!!
Wow most would of given up on this I think, but not Sorin. Getting that tiny track half way down the layers exposed and then micro soldering was very skilful. Learning so much from these videos ...Excellent repair! 👍
The first person who soldered the charging port didn't do it correctly - IE: There was no solder in the two tiny holes - Sorin told himself for some mysterious reason that this laptop has no charger ID Pin - But it did/has - All he had to do was put solder into those two tiny holes and solder the charging port back properly.
it's amazing he found the issue but that's not micro soldering.... that's another level of skill, different mentality and different equipment is required.
For the past 5 years I've been watching this Channel, this is by far the hardest repair I've seen. I mean how am I to know Gate and source are allowed to shorted together for some strange reasons. I'm really glad you were able to retrace your steps and fix the laptop. This repair is made for legends only not for people like us. I'm sure the mobo designer was biting his finger hoping don't find that ID pin. 😂
I appreciate you showing the entire repair process including the falures and backtracking. One of the best repair videos I have watched, I was rooting for you the whole time!
Just revived my dead SPA942 IP phone thanks to binge watching Sorin for the last few years. I opened the board and found that the phone received only 3.5V from the 5V 1.2A adapter. So I took my bench supply and fed the phone 5V 1.2A and the phone worked perfectly. Took an old micro USB adapter, rewired and my IP phone works like new and my adapter now has a longer cable and more wattage. Thank you Sorin!
The (intentionally) shorted mosfet took you into a rabbit hole, but your experience and proper logic thinking got you out of it.Well done Sorin, many would have drowned there!
Proper resilience my friend Even though it was a lot of failed attempts, this is truly invaluable information that would only come from someone taking a lot of time to fix this This repair deserves a whole pizza factory now
Wow. Great work Sorin. I guess the lesson is to never assume the guy who looked at it before me did a good job and there's always a possibility that he made it worse than it already was!
I accept your words (14:30 - 17:00) as a technician. We are at a heavy risk each time, we encounter a repair where something might go wrong beyond our control. I too was charging a very low price for repairs. As you said, I did not value my repair skills, I was charging lower prices. If a dead motherboard is received for repair we need not worry about the mistakes that we make while repairing, cuz, it is already in no power condition. Recently, I received a laptop that works fine only the problem was the DVD drive was not detected. Usually, I'm very careful in handling motherboard with voltages, I don't step my foot on the ground while checking with voltage. However, when I tried to measure the voltage on the DVD SATA connector of 5V Run power. The probe mistakenly slipped and shorted 5VS supply line and data line of SoC. The result was a catastrophe. High voltage with high current hit SOC. Now I have to replace the SOC or motherboard. I was really upset about the mistake and costs me 300$ to change SOC. After watching your video I realized, that I should charge high for these repairs depending on the expensiveness of the laptop. Thanks for your advice
Soren, I have to tell you, I love your channel, dedication and expertise. 90% of the time I’m learning something new from you, but I was way ahead of you on this one, even though I don’t work on notebooks or laptops. This biggest clue was the first sight of the extra pins on the power connector. When you kept having this ongoing voltage I had wondered if it was voltage from the circuit looking for that possible switch on the connector. I noticed your mistakes here was the ORDER of probability. First see if mosfet is shorted in circuit, but you never tested it OUT of circuit. That could have saved you hours. You progressed to thermal failure of parts which is always possible but rare. When I first saw all those pins on the connector, I said to myself I hope he noticed that.
The first guy that tried to repair it really messed up that port. Probably his mess that caused the chip to short in the first place. That was a good find Sorin - a tough one. Way beyond my skill level - its always a pleasure watching a master at work!
An outstanding, outstanding repair, Sorin. Always kept your cool. I felt that relief when you gave it power and it started charging properly. Wow! A master!
That was a complex repair, Sorin. Well... detection of points of "shorts" from injection of V to that shorted MOSFET replacement below the battery. Great job. 🌏🇦🇺
This is exactly the computer I want to buy when I go to university. I was so scared when you started drilling into the board looking for something you didn't know existed. Can you explain the differences between Rosin, Flux, solder paste, and when/why you use them. Most other people use the Amtech NC-559, have you used that?
No wonder it was sent to Sorin.. The only one who could solve this issue.. But not all Asus motherboards are designed the same way.. Finding the track was the way to go.. Thank you new lesson learnt
6 місяців тому
Hot air soldering from the back i learned here, from another channel i learned to use aluminium tape instead of Kapton tape. Both tips really improved how the repair looks afterwards. ;)
Whenever one mentions low melt solder I think of solder that has high bismuth content and remains liquid and aids in removing charging ports etc. Low melt solder has less lead and should not be used as final soldering since it is more brittle than normal solder. For ports I would get rid of all the old solder put the port in and ensure it is siting flush with the board. That way you ensure that the solder on the ground legs flow all the way through and makes a secure bond with both sides of the board. Maybe it is just me.
Thank you for this amazing video and for sharing your train of thought with us. I'm curious how hard would it be to find the other end of that track and put a jump wire instead? It must surface somewhere nearby, or go to one of the power control chips?
hahahaha lol nice job sir... excellent....thanks much ive learn so much from all ur videos... God Bless You... More Power... from Zamboanga city Philippines
Excellent. Maybe the start point is to follow the link from charger to computer, instead of going into the motherboard. Great job. You obviously know how to repair computers.
I also had problems with the 2n chip. Haha also replaced a motherboard because it killed it, really sucks, hope to share knowledge and experience, you are a good person
The 2 small pin need to be soldered to the board. Hence the solder tin will connect it to the ground. I believe those 2 pin is connected with charging circuit. Happened to me once with msi laptop
Hey sorin, just curious what is the purpose of the "comeback" MOSFET? P.S. Wow sorin just wow. The trick you did with heating up possible associated drivers of that problem mosfet, to increase the resistance of the circuit and seeing how that effects the short between the gate/drain - blew my mind.
that ground pin is for checking the charger is connected all the way in, if you just plug loose the charger it will not work, because a loose connection and high amperage is no good can melt the board
Makes sense. I'm guessing it's driving a pin of some ic low to signal the charging circuit to work since it takes the highest current. Do you know which ic typically controls this?
Great work sir, that pin goes to the ec chip and if you permanently connect it to ground the board won't trigger on battery power cuz the ec chip thinks that the charger is connected 😉
Awesome job, frustrating but your perseverance paid off. The wire on the charging port seems a bit fragile, maybe an idea would be to see where it is connected to on the pcb (I do this searching with one probe on the point I know so this would be the track you exposed, and put the other probe in a ball of copper wire wool and touch the pcb part by part till I find continuity) and solder the wire to that point.
(If you already have answered these questions that I also posted on the comment section of your other videos, please disregard this. Thank you. ) I have two questions. Q1 = I have a patient, an Asus laptop, its battery is no longer working and is removed already, so it only runs on its charger, which is also an Asus, and has a voltage output of 19.32v. Now I want to run it on our solar power system, so I cut the wire of that Asus charger so that the plug remains the same, then I connected the wire to my boost converter, dialed to exact 19.32v volts, the same as the Asus charger's voltage output. But it didn't work. The charger cable only has two lines, one for ground and the other one is the positive line. I didn't see any extra line(third line) that can be used by the charger and the laptop for them to communicate and be able to recognize if what is plugged in a dedicated Asus charger or not. I am confused why it didn't work with the boost converter, since that boost converter is 300 watts, enough to provide power, and it is also the same boost converter that I use with my other laptop like my Acer Aspire, which works perfectly fine. Q2 = The same asus laptop turns on automatically whenever I plug the charger. But the weird thing is, every time I plug the charger, the laptop turns on for a very short moment, enough to display the Asus logo, then shuts down again before the windows opens then restarts automatically and then it is finally open. I hope you shed some light on this issue and I really appreciate your help and your amazing tutorials. God bless.
Hi Sorin, regarding the main power rail input MOSFETs, it is always the case the gate must be 25Volt or it's only with specific laptops? The knowledge you share is priceless
Yesterday i've got same fault, gate short with source but when remove is ok, i soldered and is ok, plugin and short. I've ordered chip. Zbook 17 g3 Chip for 3.3v 5v and short superio only.
When you were talking about the old times and said: (you got that fear of charging for the fix) it's not fear sir it's PRIDE, AND THANK YOU SO MUCH SIR
One of my last jobs before I moved from the US was an older man with a dead bios battery in a laptop, you could see the battery removing the hard drive cover, but you couldn't get to it. I told him $70, and I would split the case, replace the battery and repast CPU and clean the fan, he got all upset and said,"that's outrageous". Handed him his laptop and said thanks for stopping by. (gtfo) politely. People are interesting, that's a fact.
Without an annular copper ring, there is no copper connection inside the hole. There must always be a copper sleeve down the hole, if you want to connect something properly in the layout. I just wonder, why the layouter has left the track but no trough-hole connection? Usually, we delete unused tracks because we need to minimise antennas in the design.

Sorin is the best lol

is 4 am and i was supposed to go to sleep 2 hours ago, i just couldn't keep my eyes off of this one, what thriller sorin, better than any marvel movie
Because sorin is not woke rubbish!
haha true :)

Hello🤝 this is what happens when you repair someone else's work, you have to wonder what our previous repairman did. Amazing repair.👍👍👍👏👏👏👏👋👋👋👋👋
I appreciate you showing the entire repair process including the falures and backtracking. One of the best repair videos I have watched, I was rooting for you the whole time!
this customer is very lucky to have someone like you.
I can't imagine what an emotional rollercoaster it was. Great job, man!

amazing repair sorin ....a totally epic repair ...so proud of sorin that we have him in the uk ...sherlock holmes of track finding ....
Proper resilience my friend
Even though it was a lot of failed attempts, this is truly invaluable information that would only come from someone taking a lot of time to fix this
This repair deserves a whole pizza factory now
This is why almost all repair shops, including the Brands say ´´It is damaged beyond repair´´....!!!! Great video.
Wow. Great work Sorin. I guess the lesson is to never assume the guy who looked at it before me did a good job and there's always a possibility that he made it worse than it already was!
Best part of being a technician.
Other shop cannot do it, but you solve it.
Need to charge extra penny for this job 😊.
Awesome Repair sorin ❤
I don’t know if anyone who would have taken the time to repair this computer.
Thank Sorin is the best very patient person
Just unbelievable.... Drilling deep like a proper forensic expert. wow 😮. Wonderful Fix.
What a marathon troubleshooting session! Some technicians create more problems than they solve, giving you more work. Nice save Sorin.
Wow , I'm Out of Words !! Amazing and by far the hardest & complex maintainance we ever seen from Master Sorin !! Hats Off Sirr 👏👏
Sorin will drill to any level to finish the Job....Wonderfull Job...
Well done Sorin. you never gave up and finally got the work done. That's super amazing!

Your most remarkable repair this year, I think. 😊
Awesome Job!... This was a crazy one, but the beautiful thing is you never gave up... You Won!... "We have Charging!"
Bravo Sorin , cum de ți-a venit să te uiți la pinul ăla incredibil, felicitări 🎉
Incredible job here Sorin! Wooooow..this was reallt hard. But you are a real detective.
Well done Master!🎉❤
Great repair, learned a lot, I’m glad you don’t skip any parts of the repair process! Thanns
YOU have work on this various laptop computers since 2013-2024 damn dude you are one to trust-DLH
Felicitari,imi place ca esti atent la detalii ,un detaliu mic poate rezolva o problema mare :)
That was a crazy repair from start to finish. Great job. Love your tenacity.
Electronics Repair School... We fix your motherboards layer by layer... 😎😎
An outstanding, outstanding repair, Sorin. Always kept your cool. I felt that relief when you gave it power and it started charging properly. Wow! A master!
Now THAT is perseverance! Well done Sorin
Thanks!
Proper high level repair. Congratulations !
he went full doctor mode on this one 😁
That was a complex repair, Sorin. Well... detection of points of "shorts" from injection of V to that shorted MOSFET replacement below the battery.
Great job.

I think this job is one of the best educationals I've seen in all the years I subscribe here, and it was when you used headcam ..looong time ago
Actually at 30:42, on screen charging sign appears while you work with charging port. For a very short time
OMG, SORIN IS A LAPTOP WIZARD. THIS MIGHT BE BLACK MAGIC HEHEHEHEHE SORIN YOU ARE THE MAN! Thank you.
Sorin, now that is properly callibrated insane job for you and a nail bitting video for us, isn't it.
I really enjoyed watching you chase this fault down !! Great video
You are the man sorin, I knew you never give up
Thank you for this amazing video and for sharing your train of thought with us. I'm curious how hard would it be to find the other end of that track and put a jump wire instead?
It must surface somewhere nearby, or go to one of the power control chips?
The best repair till now. Great job Sorin!
A wonderful cinematic film and director. My sincere regards to your honorable person
Hi Sorin, unbelievable that you fixed this laptop , what a job 😅
Nice done! You have that skill to solve!!! We got picture of the charging! ❤
"Try to be more confident, dont be shy to ask for money" tnx Mr. Sorin
hahahaha lol nice job sir... excellent....thanks much ive learn so much from all ur videos... God Bless You... More Power... from Zamboanga city Philippines
Excellent. Maybe the start point is to follow the link from charger to computer, instead of going into the motherboard. Great job. You obviously know how to repair computers.
Wow sorin the great job bro
No schematic no anything
Don't worry sorin is here 😂
Calibrated wire 😂💪💪
I also had problems with the 2n chip. Haha
also replaced a motherboard because it killed it, really sucks, hope to share knowledge and experience, you are a good person
Wow this is why Sorin is the best of the best! 🎉
that was simply work of art, thank you sorin
This really was a work of Proart😂
Will be easier if you got the board view and schematics 😊
Great fix Sorin!
Sorin sounds like a different person at 4am
The 2 small pin need to be soldered to the board. Hence the solder tin will connect it to the ground. I believe those 2 pin is connected with charging circuit. Happened to me once with msi laptop

@@johnbaker26 no clue, i know it exist but don't have any schematics of a board with it, i will think is for the EC to control it but how i don't know
14:32 In fact its price maxes up to 7K GBP :)
I have to give you this one too. Unreal work!
51:42
❌Sorin with thermal camera
✅Sorin with Burned Finger
This was a hectic and difficult job. Well done Sorin
Wow Sorin you are the master and you can fix anything well done really enjoyed it thanks 😊
Great work sir, that pin goes to the ec chip and if you permanently connect it to ground the board won't trigger on battery power cuz the ec chip thinks that the charger is connected 😉
I can only give one thumb up?!
This is craaazy!
Not much surprise Bro I've seen this a lots before I fixing Japanese laptop in Japan 👍good job Sorin !
I'm really curious to know where the track of that pin go to connect...
Awesome job, frustrating but your perseverance paid off.

Wow! Great fault finding! Will keep this pin in the back of mind
Good job!!! It' s hard but yu' ve done it and I' ve gotten many skills from yu. Thanks Sorin
Hi Sorin, regarding the main power rail input MOSFETs, it is always the case the gate must be 25Volt or it's only with specific laptops? The knowledge you share is priceless
Well done Sorin. That was like watching an epic mystery movie. 👍👍👍👍😮
Great work Sorin 👍
Yesterday i've got same fault, gate short with source but when remove is ok, i soldered and is ok, plugin and short. I've ordered chip. Zbook 17 g3
Chip for 3.3v 5v and short superio only.
Wizard of electronics. No one like you sorin.
Great fix. These are exactly like modern cars where they over complicate things for no reason. Nightmare.
When you were talking about the old times and said: (you got that fear of charging for the fix) it's not fear sir it's PRIDE, AND THANK YOU SO MUCH SIR
Yeah, probably u r right
I see your Diablo IV shortcut ;) love ur channel thanks for your work.
Bravo Sorin. Roller-coaster emoțional

it seems your video length is calibrating with the wires you are using. great job sorin.
Epic job, nicely done.
Good job mate 👍
great job, learn a lot from this kind of fault. I belive Sorin too.
Hey Sorin your so great , fantastic work , Congrats :) even I'm not technician...
Without an annular copper ring, there is no copper connection inside the hole. There must always be a copper sleeve down the hole, if you want to connect something properly in the layout. I just wonder, why the layouter has left the track but no trough-hole connection? Usually, we delete unused tracks because we need to minimise antennas in the design.
Not seen (or heard of) a ProArt laptop before - I wonder is the twiddly knob thing is something to do with video editing maybe?
