He is using both hands when writing!!! I love this guy!
I practice laptop repair but on my second laptop repair is hard because the laptop is working on battery only or charger only. When i plug the charger it's shorted on my bench power supply but when i plug unplug its works some time. You don't have video like this that's why i don't have an idea but i think it's a bad charging chip or some protection diode.
The guy is a genius, calm and very patient. love his way of dealing with the issues , keep up the good work
Agree totally, great video and information. Also, he has the ability to draw a near-perfect rectangle with his off hand! 5:30. Hes just showing off now
How did he add the amps to see which component was getting hot? Did he put the ground probe on the ground pin and the plus probe on the plus pin? And to check if it was short he used any two points and if it beeped it is shorted?
THE ONE AND ONLY ELECTRONIC MASTER
YOUR VIDEOS ARE BETTER THAN A SCHOOL
So true bro, love the way he dissects things
Please never stop making Videos.
its amazing
Thank you very much for your repair videos. All over the world, you have taken so many youths out of the streets with your videos. Thank you Sorin (Prof.)
I have watched this episode several times and each time I watch it I learn several new things. Thank you!
Francis Mannion really enjoying these videos...btw Francis do u know the 2 points where he touched the power supply to send the amps to heat up the capacitors? Barely seeing where he touched it...

Any ground point with the drain of The MOSFET
I've watched this video over and over to help me diagnose an Acer swift 3 with similar problem. Since finally getting a linear DC power supply off eBay, I also put about 2 amps of power through my board and found two resisters heating up! One with no sign of damage, and another that had scorch marks coming from it. I've replaced both using a hot air rework station and resisters from a donor board. And after a couple trials of using the hot air gun to rework the solder... I plugged it in and VOILA!!! LET THERE BE A CHARGING LIGHT, AND BOOT LIGHT!! Thank you so much sorry. Can't remember your name. But I do love your teaching style. You give hope to those who may know theyll never be smart enough to "design a car" but at least you help them change the tires if you know what I mean. Thanks again.
i just starting learning electronic. I finish studied for Information System but i learn nothing in university. You are amazing teacher. Good work.
I found your channel few days ago and today I fixed my first motherboard (Asus K53SD). I found a dead mosfet using 10 euro multimeter, replaced it using simple soldering iron (I attached piece of steel wire on top of it, so I don't damage other components). You are a good teacher. Thank you. Keep it up!
Yes you are good at what you do, no questions asked. After watching your videos I’m thinking about starting a repair business and channel, but I don’t want my channel to look like I’m copying your channel. I can just about guess at what you will say. JUST DO IT. Love your videos. Thanks.
I am not quite interested in electronics by the way my department is mechanical engineering. However, his approach to problems and issues in a very well professional way, his patience and no editing etc. makes me watch his videos. Thank you!
I'm also an electronics technician but I never get the chance to practice my profession anymore. I'm really happy to learn new tricks and tips from you.. continue with more videos as you are a big help to many technicians like me... :)
A very smart and a good teacher. I'm learning a lot from you. Thanks
Even though I am not a technical person, I like to see your videos. Very Good Sir.
Sunteți uimitor Maestre... Multă baftă și succes în continuare... 😘😘😘😍😍
Uimitor desigur, urmaresc cu mare placere toate video...
I loose my words when i look at your videos. You are THE BEST i ever saw. I learn so much from you. Please never stop your wonderfull videos. You are a wonderfull person. Thank`s a million times.
Thank you very much. After watching this I managed to repair my Acer Aspire 5560 which had a faulty capacitor. No power/charge LED on the laptop with or without the battery. I had 19v from the power supply but when I plugged it into the laptop the voltage dropped away quickly. Watching this video helped with the diagnostics. Thank you once again.
Thank You Sir Sorin for all your instructions!! i actually managed to fix my acer laptop using your method, i didn have a multimeter nor the tools that you have just a soldering iron, i used 2 9v batteries connected to each other instead of the linear power supply that you have, i thought i didn have anything to lose anyway, to my suprised one of the chip started to heat up when i press my hand all around the motherboard, i removed that chip(i didn have a spare one)
and the laptop booted!! i do not know how long it will last though, Thank You Again Sir Sorin!!
Nice one, I don't have a linear power supply and I have the same issue I will test this later, Thank you,
Hello, can you please elaborate a little more in how you made your linear power supply with 9v batteries? My dell charger cuts the power supply and i don't have a linear power supply either.
i don't understand very well English but I understand by your great video .you are the best teacher in UA-cam
You're an amazing teacher Sorin, great work as always
I like the head mounted camera view. Gives us a nice view of how you see things.
the first "How to repair " that actually did the repairing successfully!
You make it look easy. That's because you are the master in electronics. Thanks
The very best repair guy on UA-cam.
Can we stop and admire the fact that this dude can use both hands to write?
I honestly can't tell if he's mainly righthanded or lefthanded
🤣🤣🤣🤣🤣🤣 THIS IS THE FIRST THING I NOTICED ALSO 🤣🤣🤣🤣🤣🤣🤣
@virus killerism but no one wants to read your "short stories".
@@glitchd1_ oooooo damn
@@noureddinemerradou2806 lol
Probably left hand.. in the past people who where left handed where almost forced to write and use the right hand, so people like him are able to use both hands
Always is nice to reminisce the beginning.
I always watch your video. Love from Philippines.
Thanks to this, I found the broken capacitor on my E6540. Was one of 4 in parallel, so just got rid of it. Works like a charm again!
That's awesome!! Do you mind telling me where he put the leads when he transferred the Amps to the Motherboard? He didn't say anything at all so i got lost.
@@thingshappen9199 He put the negative to a spot where a screw is. Those are all ground. He put the positive on the last FET output. I have just used the chargeport connection in my case.
@@jdgmeester Ok. So to run the current through the motherboard he place the - lead on ground and the + lead in the FET output? How did he know to run 1.5 amps?
@@thingshappen9199 to be able to dissipate enough heat to locate the issue, you need a little power. If you generate too much, you will burn stuff. You could start with 1 Amp too.
@@jdgmeester ok so 1-1.5 is the way to go in laptop mobos. Nice.Thanks. your awesome.
Fantastic, simple explanation to also help teach service techs how to find shorts, Sorin!.
Awesome, keep it up!.
Foarte tare
Before watching the video I was almost sure the issue was a MOSFET or a voltage regulator, you made me think outside the box, Thanks teacher

Excellent work !
Good Video, Thanks, I learnt a lot, Thank you.
Where do you put the probe to inject voltage? Also would you be able to just put the charger on just to inject voltage? Sorry I'm just a beginner and love the way you teach your videos, your very down to earth.
First time seeing you replacing a capacitor! but the replacement cap is smaller... i was thinking you where looking for a cap with the same size.. it's hard to know the value of these smd caps but surprisingly it's working
that's the way to show how to fix something, great technic, wonderful !!!!!
Thank you :)
You are a genius sir...
