Learning laptop repairs - Teaching lesson for beginners

No, laptops fail rate is the same compared to desktop or any other electronic. At desktop, if it fail people can just easily replace it

better than a lesson in school!!!! fantastic!

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!

That's was I was waiting for searching in the Internet 🔎👌

I'm looking forward for the next video sir. Thanks. u are a rear gel

I whaching 2x speed...Thanks Sorin...

I just started to watch your videos from South India. Intersts me to watch more and more. Thank you sir.

Great videos !

Ty looking forward for more video like this that could give us knowledge in troubleshooting board problem

Hi Sorin, hopefully everything would be fine, waiting for the second video. Thanks

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

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

Teach me sir.

Thanks for that nice lesson but we need to know about 3.3 and 5 v too

I am very keen to take part in your course I believe you are one of the best out there and I love your teaching style.. 👌

Thank you, thank you, thank you! May God grant you long life.

Great job

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...

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.😀😀

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.

Hi sorin ,in your next video please expline what is meaning of input circuit .thankyou

Do you know how to repair laptop touchpad cable problem the conctoer on the cable disappear?

Excellent lesson very helpful

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

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.

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

want more videos :)

thanks for the learning 🥰🥰

Hello sorin ,if I replace a channel n MOSFET with a channel p MOSFET would it still work

Thank you Sorin!!! I am waiting your next video!!!!!!

very informative master.thank you

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 Sorin for a nice informative video

What about this programer? EZP2023 High-Speed USB SPI Programmer+12 Adapters Support 24 25 26 93 95 EEPROM 25 Flash Bios Chip

Im not a member but still be able to benefit from your video.

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 ❤

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

Thanks to you Sorin 🙏

thanks for the lessons

We are waiting for 3.3 volt vedio

Please make a vedio on 3.3 volt

Thank you

Thank you master for jour job 😊

Very good explantion sorin i realy like it.excelent content
its a proper long explanation tanks

Sorin creates a 10 min laptop repair channel, posts a 1 hour video.
Very educative video, thank you sir.

Türkçe çeviri olsa harika olucak :) ingilizce bilmiyorum fakat yaptıklarını anlayabiliyorum lâkin bu yeterli değil :(

this is amazing Sorin you are the best!

Keep focus on the basics,...excellent advice
