Extremely informative and entraining. It's like watching Sherlock, but with electronics. Thank you!
Totally agree with you :)
I only can agree, this guy taught me so much, it is incredible how easy and understandable he makes things. I just separated my iphone xs mainboard on my oven, controlling the temparature with an ir termometer, it worked well and i see now that my charging ic seems to be the problem !
He is GOD for me...
You are surprising, not only because of the simplicity that solves things that are complicated, but also because of the patience you have in explaining in such detail. I'm watching every video of his like it's the best Netflix series, and I can't help but be amazed. I acknowledge that I have learned beyond what I thought I imagined, thank you for your dedication.
A big greeting from Argentina
You are good, the best of the best. I'm watching everyone of your videos, thanks for sharing you knowledge.
Thank you
No no thank you 😀
I agree 100% This guy knows his stuff.
Thank you dear sir. :) normally i dont comment on videos but you sir deserve it. keep up the good work.
Savage way - "bring amps and see what it getting hot". Love it!
YES, you are good ! Using ohms, current and volts you work your way through complex circuits and solve difficult faults.. I like your term " bruit force" ! A great description.
I love watching you fix stuff, because you make it seem so easy and when i tried to do it myself it turned out it is not that easy. :D
I had the same issue with my HP 15. Found this video, removed the same diode and hey presto! Many thanks
You really should add a 25v zener diode to protect the laptop for over voltage.
I don’t like it that Sorin don’t add a new one too...
@@Todestelzer The diode don't protect the laptop, that's why it's in Sorin's hands. It's purpose is to stop the laptop from working when another power adapter with only a few volts over spec is used. Voids the warranty if use any power adapter other than HP. The fuses on the board protect the laptop and using the correct power adapter is what really protects the laptop.
Bravo Sorin nice Lesson!!! Keep the school running!!!
You're a genius. I always spent time watching your videos.
Simplu şi la obiect.
Clipurile tale Sorin sunt excelente, multumesc pentru ceea ce faci !
e roman ?

From Last week I Found Your channel on RUclips and that's what I am searching for. Now I watch your video everyday. And I like your beginner series put some other video like this. Thanks for Everything 👌
You not only a good engineer but also a good teacher .we can learn from you very easy way with difficult problem and this is amazing.
you have a very straightforward way of teaching your troubleshooting skills. great job.
I have the exact same problem, and to think I found it myself with a chinese multimeter and a zippo petrol is beyond me. If only I came across this video earlier. I should mention that its my first time trying to diagnose a faulty motherboard. You sir are the best of the best. I told everyone that same thing you told us at the end. THE LAPTOP WILL WORK WITHOUT THE DIODE TRUST ME. Its only there to protect from universal chargers which exactly was the case of my laptop and why that diode went faulty. Thank you for all your lessons sir.
one of your best videos of all time
I don't know whether I'll be troubleshooting all that stuff that you do but lemme tell you one thing I watch them just to feel good and get pepped up. So much positive energy. Say suppose I cook a nice meal today and people compliment me that's because of YOU. Your , amps, volts and ohms makes it possible. 😀I think I should watch your video first thing in the morning and then go about my daily business for you feel great the whole day whatever happens. You deserve kudos. Thank you so much. Good luck, much love and best ever. Cheers. 👍😍
bro you are a very wise guy there are a lot I am learning from you
I have one word to say to you, a genius
Hi sorin , it was one of your best video ,it was perfect .please upload more .keep it up
Now I want to go back on my field of work and fix things again because of you Sir.. Your the best!!
I think thermal camera is better However, you are an expert
The diode is their to punish the consumer for using a copy cat charger LOL that was a nice and quick repair video as always
I used a 12V / 21W bulb (from my car) in series with the 19V from the power supply to find shorts. It works fine and costs nothing.
+ -----------(12v/21w)----------- > 3A to test motherboard
How does it work..can you teach me please
You have a Gods gift.. Very nice.. God bless you brother
Thank you so much. We benefited a lot and learned. Provide a clearer explanation Thank you, teacher
You've taught me much about motherboard repair. You're a very good teacher and i can see your channel going very far. Hope for the best for your future :)
I'm from Morocco and I always watch your videos. Thanks
This is great lesson. I did not know that power supply 19V can work on so high voltage. And, of course, a purpose of that diode now is known. Thanks.
Thank you so much sir for this video and really grateful and thank God I met you early as I proceed in my journey as a Computer technician. You are my mentor and I look up-to you to become better
Hi Sorin , hope all is good for you & your family .Weather been a bit hot . : -}
super tare :) daca as fi avut un asemenea profesor in liceu eram departe. multumim pentru lectiile predate
Great job mr. sorin! 2 thumbs up!
I really appreciate your lecture videos sir, you are r really my mentor because following your videos has really improved my skills. Once again thank you sir.
Well done mate, you have mad skills.
Time is money not the key, hi hi , salut Sorin, numai bine
i love your teaching and how to repair loptop
Yes you correct sir...and what I am understand about this 19v diode is spike for mother board ...
Thank you for sharing your knowledge and experience!
You are my best favorit youtuber thanks .old school heeee
another great video ,the explanation so clear ,, ty for this video sir
Great mr Sorin, you are the best!!
Another great video. Thank's a lot SIR! Did happen on my laptop. I took the diode out and it works now with my china charger lol. Thank's. By the way, you're the best! I learn so much from you!
Thanks a lot for sharing your experience and all those best practices.
sir u r excellect . i always see your video and many things to understand. u r the excellect hardware teacher.
Thanks for Another great video! hope you get more complicated repairs for us to be able to learn more from you. =)
Removed the same diode as you did and the mother board went live. Thanks so much....YEAH?? 😂😂😂😂
Wow man your so good, i like all your videoa its give me a lot of knowledge on how to troubleshoot correctly..
God Bless You... MasterBoard Saver ;)
Very professional, thanks for a great video and for explanations! you are a great man!
Good work
To punish, not protect. I have had this happen several times. Especially with Dewalt chargers. They do not like square wave power supplies. And it is only the Zener diode or coils with micro Henry's.
Hey chief..
Thank you for the new lessons. Thank you for the 21:40 information.
When i was watching your first video i was like, i don't know whats this dude doing. I don't know how he is gonna fix this.. at some point I've got interested.
And now I'm here with some knowledge (like a cup of water from the sea). Now i think i should try to fix a real laptop motherboard. I'm gonna get one from junk yard. I'll try to fix it. (I know its too early, but let me try😂😂)
Keep up the good work chief..
God bless you..
You’re done a good job
Sir,can you please do a video on how to use the power supply on motherboard the amount of current and voltage when looking for short
ok, i will
@@electronicsrepairschool yes we are expecting this please do it
Did he do that video. I don't see it. Please
@@eddieloius4592in almost all video of his where the motherboard is short,he uses power supply to inject some voltage to find shorts...I think,u just have to inject voltage which wont exceed the amount of voltage on that particular power rail,dont inject 19v into a 1.5v power rail,1v with a reasonable amount of amperage and some petrol would be enough to spot a short component getting hot
Thanks to give practical knowledge
Great Sir ....big fan of you
You are so good and skillful man.
Many times I watch your videos, genius one :)
great professional, and humble enouph to teach others, thank you
Great as usual, laptop repairing lesson. Thank you a lot.
Could be possible to have a dead laptop with more than one kind of component shorted to ground?
can be...
nice way.. very nice thanks for sharing your knowledge..
Very very good ripering
your are the best! i cant stop watch your videos, i am a laptop tech but not as good as you ;)
👍👍👍
Thanks for sharing your knowledge
I have seen this diode shorted before in other similar laptop repair videos. It is for reverse power protection. But if this diode shorted out it may have done so to protect the rest of the power circuits. So by not replacing it there will be no protection from this happening again. So maybe it is better to replace it.
Yeah, the only think I am not agreeing with Sorin it's not replacing the stuff he's removing. I believe that they are there for a reason and should be replaced, at least from another old spare motherboard. Other than that he is great at explaining and teaching us electronics repairs.
sir i very thankful to you for explaining each step wise and good suggestions thanking you sir
I love to watching your vedios very informative .great job boss
Man, Sorin rules, I was going nuts thinking "He has to replace that damn diode or the board will be dead"
There is still one another way to find a short, if it is a mosfet short.
Gate to source/gate to drain test in diode mode.
An you should NEVER put 19v on 19v rail especially with 3 amps.
Because if there is high mosfet short - you'll burn something , cpu of gpu... their resistance is very low, and looks like short.
First you have to check for short at low voltage coils to +19V, and then, if there is no short, you may come with 3V 1A, or better 1.5V 1A.
That was a transient voltage suppressor diode. The laptop is no longer protected against static discharge, or lightning damage, or dodgy chargers. :)
Nice job. But can you please explain your method in how you find the short using power supply, and thank you a lot Mr. Soren.
Its simple..if there is a shorted parts.it will get hot,try to watch other videos of mr.sorin.
ive learnd so many here as a simple way to power :)
Amazing videos !! I will buy thermal camera to avoid burning my fingers😀
I'll burn my fingers, cause i can't afford to burn such a hole in my pocket rn 😂
Tnx for the nice videos.. I actually use a temperature meter to locate the defective part. It is not so painful :)
lucky you :)
Hi Sir, around how much should I charge for that job, you have any idea?
You are an Electronics Spartan believe me ... RUclips needs to do that "Robot test" thing on you
What would you have done in his place?
guys you buy the power supply 30v 10a. thats the way how check shorted board first we have two switch mosfet. and if u dont know just download the schematic diagram
Great way... Savage way.... it's awesome..
Nice video,great job as always...
I think protecting MB with a zener diode is a bad idea [when you are using a switching power supply]. Just think about the higher spike like 35-40V..
same problem sir in Compaq Presario CQ40.....i hope i fix it.....thank you very much for the video......great...great great
I love zeners alway easy fix
Nice work here, your work pattern and teaching technique are very easy to adapt, love the touch of humour while teaching too, makes learning much ore easy. Please, do i need to get a special kind of multimeter or just any good multimeter is ok to use to diagnose a motherboard? Awaiting your response.
Great video!You explain things clearly.Thanks a lot :-)
Big fan and love watching your video's :-)
learn from you everyday. Thanks
U are a genius Sir, thank you!
nice job, and good video, tanks for sharing.
thank you man good work
a master technician move
great job sir
Thank you :)
Sorin thanks for another great tues videos.
Very nice. Thanks for sharing!
you are my guru..thanks
Up to thirty volts even... The mosfets used in most models these days are rated as such.
if it was there to protect the board, you will also have a fuse in series before the diode .... but this is not the case.
Thanks you man!!!!!!!
I liked your video, you got a new subscriber... well explained
Thank you Professor
youre very good sir
