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

[@FlorinBalanescu]

Extremely informative and entraining. It's like watching Sherlock, but with electronics. Thank you!

[@Mustafay3sil]

Totally agree with you :)

[@diemiesepetra]

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...

[@Oak690]

Savage way - "bring amps and see what it getting hot". Love it!

Bravo Sorin nice Lesson!!! Keep the school running!!!

[@Mr138AJ]

Thank you dear sir. :) normally i dont comment on videos but you sir deserve it. keep up the good work.

[@reynaldofigueroa3372]

You are good, the best of the best. I'm watching everyone of your videos, thanks for sharing you knowledge.

No no thank you 😀

[@Oak690]

I agree 100% This guy knows his stuff.

[@cavan5]

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.

[@kouachinadhir8975]

I have one word to say to you, a genius

[@milskater]

one of your best videos of all time

[@johndavowski4119]

I had the same issue with my HP 15. Found this video, removed the same diode and hey presto! Many thanks

[@Todestelzer]

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...

[@arnolduk123]

@@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.

[@noway4040]

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

[@knightwar3]

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

[@joelmendoza7776]

You're a genius. I always spent time watching your videos.

From Last week I Found Your channel on KZbin 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 👌

[@dricklorenz9340]

you have a very straightforward way of teaching your troubleshooting skills. great job.

[@Marko_Djuricic]

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.

[@rayofcreation3996]

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. 👍😍

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

[@arifryo6823]

How does it work..can you teach me please

[@prosperdeogratius4888]

@@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

[@aneezaliyar1901]

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..

[@PaulHigginbothamSr]

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.

[@4EVERGR]

Great as usual, laptop repairing lesson. Thank you a lot.

ive learnd so many here as a simple way to power :)

[@maelcrusty8243]

Thanks for Another great video! hope you get more complicated repairs for us to be able to learn more from you. =)

[@victorzedwings]

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.

[@OneMusic21]

Many times I watch your videos, genius one :)

[@user.fedorman]

[@lucianofz788]

great professional, and humble enouph to teach others, thank you

[@worroSfOretsevraH]

That was a transient voltage suppressor diode. The laptop is no longer protected against static discharge, or lightning damage, or dodgy chargers. :)

[@rashh77]

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.

[@TFT_JOURNEY]

Its simple..if there is a shorted parts.it will get hot,try to watch other videos of mr.sorin.

[@ravindraadapa2952]

sir i very thankful to you for explaining each step wise and good suggestions thanking you sir

[@tonelixj2126]

I love to watching your vedios very informative .great job boss

[@nasernasra6381]

thank you man good work

[@Sidman723]

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.

[@igork.2271]

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.

[@Bhabaparernaiya]

Great way... Savage way.... it's awesome..

[@igorrizvic4699]

[@jerrichcastro4651]

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

[@joeycarr1398]

Hi Sir, around how much should I charge for that job, you have any idea?

[@DanBurgaud]

I like your idea of using zippo to detect shorts/hot stuffs...

[@radiotriggered2096]

Up to thirty volts even... The mosfets used in most models these days are rated as such.

U are a genius Sir, thank you!

same problem sir in Compaq Presario CQ40.....i hope i fix it.....thank you very much for the video......great...great great

[@vishwajeet08]

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..

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.
