A failed repair, but a mine of invaluable lessons on repairing approaches, testing and diagnosing. Thank you Sorin for a most enlightening electronics tutorial.
Liquid damage is one of my least favorite repairs. Win some, loose some so we still have to try i guess.
Sorin 3v is always present line and check 5v line also. The board is going is s5 state but when you press power button its drops the current clearly there is some short or ic fault on S0 state/line which is preventing board to switch from s5 to power on s0 state. You need DSO to check if any line has pulsing voltages or short
26:00 Sorin, you clearly connected the duck in reverse, that's why the current goes down instead of up
You are right, ~1ohm too low.
Got a spreadsheet with good vcore readings, and good reading for 10th gen is:
i7-10510U, 4ohms and takes current 1A
I do some very occasional odd repairs requiring soldering and always had a hard time. I made some of that rosin and isopropyl alcohol mix flux and it works wonders, really good stuff and very effective. Two things I learnt to make things easier is good quality solder wire and flux, these 2 are essential. Thanks for all these super useful and educational videos.
Hope you are not using lead-free soldier
Thats bad, thats proper bad

I like these "failed" video probably even more than "success" videos. Keep going to share these !
Personally, I think they should make the CPU replaceable. Like they used to with a Ziff Socket. But that would make the laptop thicker. But there seems to be a lot of these going out.
Lol this guy is pure gold to watch and for fun, and for knowledge. Answering the people that will say shorted below the chip right on spot :D
Nice to see you try to fix this to the point you know it’s a end of story 💀 dead
Thank you for the time to share with us. Have a great weekend
Sorin, am from Ethiopia am technician and ur best teacher you know i don’t have power supply just multimeter I wish I had but am fixing things thinks for all knowledges.
This time you failed, Sorin, but you know you can’t win all the battles… So let’s move on for the next challenge. Happy to say that your tips helped me fix a Samsung laptop with liquid damage, especially your tip about the liquid flux made of rosin and alcohol. Thank You!
Bună seara sir Sorin! Eu nu-ți scriu în engleză dar rămâi eroul meu. Atât înfrângerile nenumarate cât și victoriile nenumarate, fac parte din munca noastră de zi cu zi. Cel mai important lucru este că în viață ai fost sus și ai știut să cobori și iar ai urcat,ceea ce dovedește că ești un mare învingător. Nu te lași bătut pentru nimic și asta dovedește că ești si vei fi un mare maestru. Pararea mea este că pentru o victorie deplină în toată această luptă, mai este necesar de o stație de reflow, rebaling IR. Pentru a inlocui CPU-uri sau poate nubse merită. Acum numai tu știi mai bine dacă merită sau nu. Ești de nota 20 cu felicitări! Multă sănătate și mai aștept videoclipuri. Așa pățesc și eu cu placi de bază dar mai întâi masor rezistența de alimentare procesor pentru a nu munci mai deoarte în van. Mulți au fost de acord să le schimb placa de bază după ce le-am explicat cum stă situația. Nu merită să cumperi de la chinezi piese de schimb deoarece este loterie curată. Am cumpărat 100 de tranzistori si nu am găsit doi să-i imperechez. Asta spune multe. O seara plăcută ție si familiei tale!
Nu cred că stația ar fi problema ci proveniența procesoarelor. Cum a zis și el, nu ai cum să le cumperi de la producător... și ce găsești cel mai probabil sunt luate de pe placi de bază defecte fără o garanție că procesorul e bun. Cum ai zis și tu, e pur loterie. Îmi aduc aminte de 2 videouri de-ale lui Sorin de acum 2-3 luni in care a primit un chipset crăpat și un procesor curbat.
I learnt something though. Thank you for posting this video.
sorin. Dear Friend. Human energy is limited and you don't have to fix everything. I know you're doing your best. The condition of this laptop is hopeless. And you have to tell the customer that he should buy a new motherboard. Greetings to you my dear friend🎉
a) Would it have been possible to solder over the CPU from the other board? b) Maybe you could have asked the customer if he is willing to pay for a new CPU with any guarantees and if yes, solder on the new CPU. Could still be much cheaper than a new notebook.
Sorin. You are a very experienced person. Which laptop manufacturing brand is the best as per longevity, robust build quality and less failure.
Sorin: The man, the myth, the Legend! 🎉
When you press power button check on coils that which supplies generates even for split second and then take it from there
Hi sorin sir i am very happy to watch this video Why Because I learned the technique the way you can track the voltage and confirm the problem, whatever the result is either solved or not but finally to diagnosed steps
Thanks for the video, keep sharing the knowledge
Sorin, good evening. In this case much better use auto range multimetre. It show any resistens which you mesure. What do you think?
Good job mate 👍
I was fixing all sorts of electronics. Then I started to get a bunch of liquid-damaged things. It destroyed my confidence. If you see a little bit, that is workable. If the entire board is water damaged, not even going to try. Water damage is so hard to fix at times.
enjoying the repaires as always espacially the part if its a devider we r ....
Thank you master
Hi Sorin. In good condition motherboard with I5-10210u i have resistance - on core power (CPU VCORE) 2.5Ω and
Liquid damage is extending on all the board. I would not work on it. On a small area I would try. But not in a case like this. Secondly, I would never work on a liquid damaged motherboard that has been cleaned before. The cleaning process hides the affected areas. You could have liquid residue under a lot of ICs and not knowing about because of the cleaning. Basically you should remove all the ICs just to check.
Too bad. That’s the way the cookie crumbles sometimes
Resistor and capacitor sample books.
the manufacturers are gods
At least I learn here how to find 3.3V on BIOS chip
200 or 800 it's about that :) almost the same value :)))) Sorin, I adore him !
6:24 I’m a beginner and I need to ask why the next logical step is check the BQ chip and do not try to restore de 19V on the second mosfet. In other videos I’m sure it’s the procedure, I’m wrong?
the BQ chip is the chip which is triggering the both input mosfets, solving the problem with your bq chip, it will restore you main power rail
@@electronicsrepairschoolwhat could happened if I took out the mosfet and make a proper calibrated wire 😅?
Thank you for another great video! Learning (and laughing) along the way - if it looks like a duck, then it is a duck (even a fat duck)!
More vidéos.... Lové your vidéos... L'OL
I'm new to electronics repair, so may I ask... What is wrong with reflowing the cpu?
I tried to fix a Siemens 2.1 Ghz Intel laptop, that had water damage. I didn’t succeed, the laptop’s power led started, but nothing happened. The Cpu and Ram was still working.
Friday ❤
Why not bake the motherboard in the oven? I did that with my graphics card and it came back to life.
Mulțumim!
Sorin, please record some phone repair..
would be awesome if you could take a look at my acer nitro 5 it has a damage on motherboard they say at the repair shop, but no one is able to repair like you - they just wanna change the MB complete :( very expensive :'( better you take the money :D
Would you use a sonic cleaner if you had one? Once you reach the point of luck?

Where did you get that cleaning bottle from?
where can i find those datasheets
Cool..
Is there are a crack?Between 6. leg and res?
Hello boss where is your shop location or post code ?
Probably for the best. Some you fix will come back under warranty anyways. Headache.
Salut
De unde cumpărăm rosin lichid?
Rosin pasta este dar lichid?
ruclips.net/video/9xk76e7nzcw/видео.html&ab_channel=ElectronicsRepairSchool
You mix it yourself. Rosin and isopropyl alcohol (99.9%)
I went you to tech me online to repair board
👌👌👍👍
Hello🤝👏👏👏👏👏👍👍👍👍👍👋👋👋👋👋
Should have cleaned the whole board first. Otherwise worthless doing anything.
U need bgs machine
All that work and it's brain dead wow
Noiceee
