I failed fixing this laptop - Liquid damage repairs, are tricky

Should have cleaned the whole board first. Otherwise worthless doing anything.

I went you to tech me online to repair board

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)!

where can i find those datasheets

Why not bake the motherboard in the oven? I did that with my graphics card and it came back to life.

enjoying the repaires as always espacially the part if its a devider we r ....

Hi Sorin. In good condition motherboard with I5-10210u i have resistance - on core power (CPU VCORE) 2.5Ω and <1Ω ( 0.82Ω) in GFX power line (onboard graphics)

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.

When you press power button check on coils that which supplies generates even for split second and then take it from there

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

Sorin: The man, the myth, the Legend! 🎉

Good video,learn a lot of useful

A failed repair, but a mine of invaluable lessons on repairing approaches, testing and diagnosing. Thank you Sorin for a most enlightening electronics tutorial.

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

Sorin. You are a very experienced person. Which laptop manufacturing brand is the best as per longevity, robust build quality and less failure.

Friday ❤

Good job mate 👍

Sorin, please record some phone repair..

At least I learn here how to find 3.3V on BIOS chip

I'm new to electronics repair, so may I ask... What is wrong with reflowing the cpu?

Cool..

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

Hello🤝👏👏👏👏👏👍👍👍👍👍👋👋👋👋👋

Too bad. That’s the way the cookie crumbles sometimes

Is there are a crack?Between 6. leg and res?

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

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!

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

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.

Mulțumim!

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.

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.

sorin where you get your rosin?

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.

U need bgs machine

Would you use a sonic cleaner if you had one? Once you reach the point of luck?

Resistor and capacitor sample books.

Hello boss where is your shop location or post code ?

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.

Salut
De unde cumpărăm rosin lichid?
Rosin pasta este dar lichid?

200 or 800 it's about that :) almost the same value :)))) Sorin, I adore him !

All that work and it's brain dead wow

Thank you master

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

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!

Thanks for the video, keep sharing the knowledge

the manufacturers are gods

Where did you get that cleaning bottle from?

How about using ultrasonic pcb cleaner?
