Hi. I have been following your channel for quite some time now from my point of view you one of the most Genuine Teachers of electronics I have ever come across online. Being in the computer repair business for about 10-15years my version of the repair was finding what part went bad and then replacing that part which is very basic since watching and studying your videos I have a better working knowledge of diagnosing and troubleshooting. I know I still have a lot to learn but you make learning easy and fun.
I want to say thank you for taking the time out to make such educational videos on electronics repair. you have been an inspiration to many of us Please keep up the good work.
so am I...
Thank you
@@electronicsrepairschool hello, my laptop (acer aspire) dead while charging ..what may be the problem?
interesting points ,if anyone else wants to learn about
pcb trace repair
try Saankramer Electronic Magazine System (just google it ) ? Ive heard some extraordinary things about it and my brother in law got great results with it.
I second that.. Really great work.
Wow for a biginner like I'am this is just awesome! Most videos on youtube are just for advanced technitian, they're only speaking for themselves. I think the most important point here was how to follow the track, that's the key. Thank you!
Wow, you're like a russian louis rossmann that is not obsessed with mac.
That's why I subscribe.
pretty sure sorin is a romanian name
mac are providing lot of money, may be that explains this ...
Lol
Hahahah, nice put. This man is priceless.
@@IsaacOLEG absolutely, less work for more money, why bothering repairing Hp laptops that have no schematics ?
I am a beginner and have already learned so much from you. I would like to thank you for your videos and the time that goes into making them. Thank you for sharing your knowledge with us.
Good morning Mr.Sorin, thanks for coming back to bignners tutorials.
Because is always good to Lean from the ELECTRONICS DICTIONARY.👍
i loved it. more training for beginners. to be honest i never understand how you follow the tracks, today i learned first step....
There are never enough videos for those just starting to repair laptops, but this video I found excellent increasingly sorin becomes an excellent educator to find some of the easiest problems to repair and find. Thank you, excellent.
I don't even know the words to describe u, Mr. Sorin u are my mentor when it comes to electronics field
Sir may you leave long, you have real impact a lot of things in me, am proud of your channel 🍾
Thank you, makes me want to learn electronic basics, then being a better and more complete computer technician. It's so satisfying to be able to repair electronic boards instead of throwing them away..

You are a great teacher...you keep it simple. I would have liked it if you had shown where you bridged the MOSFET as a beginner just to be sure thanks.
Thank you SORIN nice beginner point o view.
as always a great job.
fast and simple short the first Mosfet and 19v is back
Sorin is brilliant man. You're a good teacher I Wish you always be healthy and good prosperity.
I just have to say your passion for the craft is one of the things inspiring me to go into PC repair
Thank you Mr ,Sorin please do more videos on beginners like the 3.3 and 5v power rail
I really enjoy your videos, i am currently troubleshooting a toshiba laptop with bios loop and no fan spinning and one with no video.
very good teacher. your explanation is very clear. thank you so much sir.
Thanks you sir your instractions saved my Lenovo G5-30, in my case the second mosfet was dameged
i love to not skipped any ads from this channel... 😊
Perfect, working on the exact same laptop, magnification was a big help. 👍
Edit: Put it back together and found the plastic on the charger tip stripped from wear and tear, positive was shorting in the port.
Sir may God bless you the way you are teaching you have inspired to do what you are doing just as a begginer GOD BLESS YOU A THOUSAND WAYS
Hi there, I really like your channel, I have learned a lot from you. Thank you so much for this channel you are an expert in electronics and I appreciate your sharing your knowledge with us. Greetings from Bosnia and Herzegovina
Sir you are a good teacher
I am also beginner and learn lots of things.
The Way you explain the things is Perfect!Thank you very much!!
Amazing video. Probably one of the best in the channel. Gj Sorin.
Great trouble shooting technique. I am now equipped to attempt diagnosing my no power on/no charge problem.
Thanks for another interesting video Sorin. I hope you can make another one with a faulty capacitor and how a beginner can approach that too. I'm facing a similar issue with a "dead" Lenovo laptop and via your videos I am beginning to get confident that I will be able to revive it. Regards!
You bridge that mosfet because you can Master. I love it. Amazing school, amazing atmosphere. Thank You. Regards
Sir, you are superb! My master always do this but I don't understand why he normally bridge that place. Today you made it clear to me. Thank you alot.
This is amazing. I have a Dell laptop for a few years, and it had been working great until a few months ago when the laptop just shut down by itself right in front of my eyes. Imagine my horror - no power, no light whatsoever,.
Your video gives me an idea what went wrong. Honestly I don't think I have the technical know how to troubleshoot the problem with the multimeter, but I'm really inspired by your video to give it a try . After all, I don't think I can do any more damage to the laptop as it is now.
Thank you so much for taking the time to make all these videos.
Thank you so much. I feel like a light has come on inside my head. I really appreciate your videos
Hi sorin thankyou for your useful tutorial video, please explain more about power rail and power supply on laptop please. Thnx
just thanks man thanks i spent my free time watching you with a pleasure .keep this work this is the reason why you are so great,because you have altrouism as person
It was really nice to hear the thinking. This helps with understanding the start of the troubleshooting process. Thanks very much.
King of the quick-and-dirty repair!
where is the advertisement..do i mis it .....nice and very fruitful tutorial from beginer view..Post more pls like this.....
What he did here is equivalent to resetting your circuit breakers when the lights go out in your home. Think of the first two Mosfets as circuit breakers that will shut down power when something is drawing too much current. On an N-Channel Mosfet the Gate must be the same or higher than the source for current to go through. On this Mosfet the Gate was 0.924v while the Source was 19.22v. In order for current to go through he jump the Mosfet to make the Gate equal to the Source thereby allowing the current through.
But what about the component that cause the surge in the first place?
It's still there and may lead to more problems down the road.
Is this a good fix?
Would you call using a penny in place of a fuse to get the lights back on in your home a good fix?
But what would be a better solution?
@@CTsparkle - A better solution would be to find the faulty component and replace it.
Thanks for the explaination. I could follow the voltage reading but I didn't understand why he would solder that MOSFET
I just want to thank you, I could fix my laptop following your tips. THANK YOU!!

What a legend. Thanks for the tutorial.
Hi, I am so impressed with your video on how to diagnose to find out a shorted circuit. I have DEAD Thinkpad L380 after changing with a new battery. I removed the newly installed battery and plugged power cord LED on switch blinked a second and went off. When I pressed power button nothing happed and system didn't start. I am afraid i have a shorted circuit on motherboard which caused dead machine. I am a biginner and no knowledge about electrical aspect and stuck with dead laptop. I would greatly appreciate if you teach me on step-by-step dignose tech.
good job sir soren i
looking foeward to watching your next videos.
