i love your long videos. I think shortening your videos to 10 minutes is a huge loss for us who love your content, your humour and like to learn the easy way-from your experience
This is 100% educative and thank you Sorin. These videos are moulding me into someone else and I would love a power sequence video with a long explaination like this, so I continue bulding from what this video has taught me.
This is what i've been looking for! I've been a sub of your channel for a long time and it really sucks what youtube is doing to you main channel. A lot of us appreciate the long videos, myself included, where you explain your thought process and help us archieve the only thing most of us want here. To learn. I thought those kinds of videos would be no more since this channel was only for short videos but im glad to see that i was wrong! Continue doing what you do best and continue uploading some long videos too, we love em!
I am watching channel around 2 years now, all the time improving my skills. The first movies was funny waiting for Sorin to come back from the shop after 5 min talk ;>. Now perfect lenght of the videos. I also watching diffeent channels but mainy this as supplying any daily problems. I am stoping movies and thinking what i will be doing if it is my problem. Then sometimes right or wrong but this is helping a lot to understand my point of understanding. Thanks of all that lessons i happily fix my 3 laptops (for my family), my car dashboard speedometer, and several smallest things. After 2 years spend on YB channels and practising I think I get kind of advanced. PS. always watching Sorin in x1.5 speed ;>
Sorin nice work, for beginners like us we real enjoy long videos, We get a lot as you keep talking when opening the computers, we keep learning rather than shortening the videos. I appreciate this .👍
Exactly! I looked at the duration & swooned!😀 No, I never mean long videos not acceptable, but it's your channel title & the video duration that's vice versa!😀
Hello Sorin, great video as you always have us used to, I hope you continue teaching us. Thank you very much, from Spain-Granada. Luckily the RUclips translator helps me follow you jjj
Sorin you try to do it from zero before now do it and led Diana learn us on a board and not in the air … and you can learn everybody to understand electronics the right way. Love you for doing this ❤
Absolutely brilliant video. I am waiting for continuation. Nice advise actually not to take the jobs when a laptop is turning on but no picture. 90% cases it's GPU.
I am admiring your criteria and your videos especially the long ones that really explains in details and practically every situation we may face, not only theoretically. Thank You a lot. By the way I am creating up a txt course which includes all the notes, comments, questions and ways of solutions for every video I watched from your uploaded ones. Hope Ill have your permission for doing that and time to do this for all your awesome videos. You will be the first one to inspect and edit this course when it is finished.😀😀
Thanks for sharing your experience, it not common or even part of our culture here in africa, am so grateful for you inside knowledge and skill teaching us how to go about laptops
Thanks mentor for always sharing your thought on all your repairs, your are one out of many who shares his heart of his skill, i have issue with HP probook X380 11 G3 EE whereby it flashes two light followed by three long quick flash not displaying to screen, and the RAM is onboard, how do i fix this problem
That was fantastic !! talking of diferets kind of imput circuits i just only miss the USBC and how it negociate then main power rail voltage.some words about Power Delivery Protocols and Thunderbolts stuff, do you have some commets about new standar of 48v@5A 240w designed for gaming laptops? I already now thant you don't like USB-C like imput power system.. you told us many times before! do you remember?, do you still keep your words? .. I reali love this long king of videos i mean over 25minutes.. it was perfect!. thanks Sorin
I am very thankful to you sir for this kind of good video because we are on learning mode so well explain each and every step to improve the skills to my knowledge additional advantage tq very much❤
For the newbies, focus on learning how to diagnose a faulty power supply! First, learn from Sorin how to identify the different power sources by the presence of inductors, mosfets, and power supply rails capacitors.

The biggest challenge I believe is to know (for a beginner) the correspondent voltage values. How should I know if there should be 19.5V and after 18.9V? Should I have 4.5v at some point or 4.1V? How to know that? It happened to you @sorin right? You thought the board was fixed...
first.big thanks to u Master.what i've learned in other place that the coil never touch the ground when we have short with ground with coil tha's mean the short is not far from the coil. my question is ok we know where is our main power rail,how it can help us to find the problem if the power is lost in some places?stupid question but i have to ask :)
Fantastic video! Almost everything is making sense. One question I had is how you know which pin of mosfet are source gate and drain? Are you looking these up (didn't look like it) or is there an easy way to figure that out? Thanks!
This is my feedback. This is the type of the video I was looking for. I learned a lot from you and others but I always wondered how I can tell if the power rail I am looking at the moment is 3.3 or main or 1.8 or whatever. Looking forward to the next video :)
thank you sir.. i'm from philippines... i've been training in laptop and macbook but i'm still confuse for checking the vreg or ldo, the 5v, 3v and the 3.3volts
I really appreciate your efforts, but we need more clarification about how we can identify P and N-channel MOSFET, and depending on what is called that name, also the source, drain and gate can be the same on both P and N-channel MOSFET. The second one that is much more important is how to measure each component on the board and what the right approximate values have to be (Ohm, Voltage). e.i MOSFET must not shorten any source, drain and gate together. The voltage on the 8th pin of the BIOS usually or always has 3.3v... So on so forth Thank you so much.
Is there a circuit that lowers the voltage after the first two mosfets. Or after the second mosfet there is an ordinary wire so that all voltages are at 19 V
Hi Sorin !!!! This is what we want !!! Not 10min vidéos. We want to learn properly with long explanation
Sorin creates a 10 min laptop repair channel, posts a 1 hour video.
Very educative video, thank you sir.
my god , you are gold to me , i work in a thrift shop , many laptops have survived thanks to knowledge i learned from you , ty sorin

I appreciate this .👍
Sorin is the Best!!!
I have a lot of catching up ...
I just started to watch your videos from South India. Intersts me to watch more and more. Thank you sir.
dont worry for the length of the vedio
we will stay with you
you are a treasure for us .
Hello from Amsterdam. I think all your videos are awesome
Love this video, actually taking it all in and learning clearly where and how to find the main power supply. Can't wait for the next video
Sorin, felicitări !!! Ceea ce faci este excepțional👏👏👏👏
GREAT!!! This is a nice video! A step by step en shown with different vendors an layouts. Well done Sorin!
Hi Sorin, love your channels. I did find it amusing that you post a 1 hour video under "10min" Laptop Repairs. :D
Exactly! I looked at the duration & swooned!😀 No, I never mean long videos not acceptable, but it's your channel title & the video duration that's vice versa!😀
Keep focus on the basics,...excellent advice
I have small knowledge in electronics and I like this step specially repairing a laptop.
Hello Sorin, great video as you always have us used to, I hope you continue teaching us. Thank you very much, from Spain-Granada. Luckily the RUclips translator helps me follow you jjj
That is exactly what I looking for... amazing... you are master sir... please make a vedio series from beginner to advance
Sorin you try to do it from zero before now do it and led Diana learn us on a board and not in the air … and you can learn everybody to understand electronics the right way. Love you for doing this ❤
this is amazing Sorin you are the best!
Thank you, thank you, thank you! May God grant you long life.
Damn, you're on fire Sorin! Thank you so much for these new beginner videos!! You teach and save me so much 💙🙏 thank you
I feel so happy when I saw 59 min.... thanks a lot Mr Sorin
What is this Sorin? A new channel? Good video as usual!
Very nice and thorough. Thanks!
Absolutely brilliant video. I am waiting for continuation.
Nice advise actually not to take the jobs when a laptop is turning on but no picture. 90% cases it's GPU.
some model always has a faulty EC or IO chip, but not hard to find out either.
You are a realy good person. I love we replace caps on the next video
Great job
fantastic video Sorin
Take your time. We are very patient 😉
I am admiring your criteria and your videos especially the long ones that really explains in details and practically every situation we may face, not only theoretically. Thank You a lot.

You will be the first one to inspect and edit this course when it is finished.😀😀
thank you Sorin for a nice informative video
Great video mate 👍
Excellent! Ioved that you found a couple of overlooked issues on the "working" boards too! Thanks for keeping it real. 73, nz5i
very useful video specially for me as a beginner.
Thanks for sharing your experience, it not common or even part of our culture here in africa, am so grateful for you inside knowledge and skill teaching us how to go about laptops

Hello Sorin
Congrats for New Channel, I would love to see more video for other electronics, Satellite and Freeview boxes, Perhaps Android boxes etc
Excellent lesson very helpful
I wish if i have someone who has this power of knowlegs , thank
you so much for this video
Thanks mentor for always sharing your thought on all your repairs, your are one out of many who shares his heart of his skill, i have issue with HP probook X380 11 G3 EE whereby it flashes two light followed by three long quick flash not displaying to screen, and the RAM is onboard, how do i fix this problem
Thank You ✨ If you can and have time can you please make some videos about power sequences, important signals e.t.c.
awesome lessons like this are priceless :)
Thank you for videos sir!
Great lesson! Where is part 2?
That was fantastic !! talking of diferets kind of imput circuits i just only miss the USBC and how it negociate then main power rail voltage.some words about Power Delivery Protocols and Thunderbolts stuff, do you have some commets about new standar of 48v@5A 240w designed for gaming laptops?

Love from Bangladesh dear Sir❤
Thank you very much,
I digest much from this video.
Im not a member but still be able to benefit from your video.
im on my way to know electronics about 10%..thanks sorin...im chris from philippines

multumesc pt info,
Hi sorin ,in your next video please expline what is meaning of input circuit .thankyou
Awesome teacher!!
Thank you for another gread video Sorin!
I'm looking forward for the next video sir. Thanks. u are a rear gel
first.big thanks to u Master.what i've learned in other place that the coil never touch the ground when we have short with ground with coil tha's mean the short is not far from the coil.
my question is ok we know where is our main power rail,how it can help us to find the problem if the power is lost in some places?stupid question but i have to ask :)
Thank you very much for this.
Can't wait for the second part of finding the 3.3 volts and all about the EC chip.
Fantastic video! Almost everything is making sense. One question I had is how you know which pin of mosfet are source gate and drain? Are you looking these up (didn't look like it) or is there an easy way to figure that out? Thanks!
thanks for the lessons
Sorin nice explained
That's was I was waiting for searching in the Internet 🔎👌
This is my feedback. This is the type of the video I was looking for. I learned a lot from you and others but I always wondered how I can tell if the power rail I am looking at the moment is 3.3 or main or 1.8 or whatever. Looking forward to the next video :)
Thanks for that nice lesson but we need to know about 3.3 and 5 v too
thank you sir.. i'm from philippines... i've been training in laptop and macbook but i'm still confuse for checking the vreg or ldo, the 5v, 3v and the 3.3volts

Great videos !
to sad that this video is only 360p - no details on the boards viewable - perhaps you can upload it again?
Try again in an hour, RUclips takes a whole to encode it all.
His Discord is good. I go there and ask for help. I have fixed things by doing this. I am not brand new, but no expert.
where is the link?
@@vincent_muriithi The link to the discord channel is right under the video.
Do you know how to repair laptop touchpad cable problem the conctoer on the cable disappear?
Thanks
from zero to hero ;)
Can you tell me what kind of copper wire you are using at 31:50?
360p? video was posted over an hour ago, utube should of done its "thingy" by now i would think
Please make a vedio on 3.3 volt
so restoring 19v and 3.3 i most important. I've learnt a lot about restoring 19 v but how we restore 3.3?
guys . who has the link to beginner lessons . understanding the motherboard and how power flows . what path the power follows
. please
🎉🎉 Nice one
hello Sorin. can you make a tutorial video on how to shoulder USB ports and charging ports for laptops for tech beginners
Is there a circuit that lowers the voltage after the first two mosfets. Or after the second mosfet there is an ordinary wire so that all voltages are at 19 V
look again from start to the end... answer is there
