I discover you 1 week ago ad I can tell that I’ve learned more in one week than years of study! Best teacher ever!

with the help of the videos i view here on this channel, i have been able to learn a lot. i finally got my own DC Power supply today and i fixed a dead laptop i have had here in my office for over a year. you all need to see the feeling....thank u so much Sir Sorin.

Hi Sorin! Happy new year! I really love your videos. Its like being taught electronic repair by Grew from Despicable Me! Thank you so much for all of your wonderful lessons and for sharing your vast real world experience. I ve learned more from you in practical terms than I have from any book. Please keep them coming! Big love to you! :o) xx

I was about to put charging wires directly to second mosfet but I did not have the balls to do it. I found schematics, and the board itself is like 40-50 euro with cpu attached. But I tried your method and everything worked. Thank you , good man.

Happy New Year! and thank you for this movie. Another good lesson

Doing jobs with your "doggy" way meaning you are a professional .Happy new year Sorin ,never change your style !

Very Good to see you back. I hope you and your family have a Great Year coming up!

Thanks Sorin for this diagnostic, I just discovered your channel and I love the way you are thinking and workind. Electronics without shortcuts is like doing world tour in Moonwalk :) Sometimes it is the only way to repair (yes, it should be used as last resort). Since client always want cheap, I propose 2 solutions : Cheap (shortcut without any garanty and only God willing) and expensive (board replacement, parts purchase/replacement). I inform the client of the benefits and inconvenience of each solutions. Many thanks for what you are doing, and "Noroc si sanatate !".

Happy new year to all our colleagues and you my master!

Hi Sorin and a happy new year. First of all. I wanted to thank you for all your work here and thing you teaching us. You teached me a lot in understanding, thinking and doing. Nice that you want go now the professional way and want try to do no dodgy way :-) I understand that it can be sometimes difficult for a repair shop that have to fight with time and costs. As an enhanced beginner I wanted to give you a tip for next repair videos. Please noticed this not as an advice. Begin all repairs with volt checking from charger to charging ports on boards to batterie . Then do always when if possible and even if not necessary a bios reset. That should also be even if not necessary always the first steps in procedure. Sometimes like you showed it, it happened a lot in eg frozen io Bios chips. Ram checks or remove a hard drive can also be rare thing of not working or booting. This Steps are quick and didn't cost you a lot of time on start. Someone told me a time ago when if I remember correctly in this same case on Ideapad. That it has to do with the power management. The batterie discharged to low and is blocked to charge again or fully charged. What exactly it solved I didn't know anymore. If it was charging the batterie manual full to reset the charging power management on the mainboard that blocks it or the charging management of the pcb of the batterie.

Just keep doing repairs like you always have. That’s what we love about your channel. What you call dodgy is genius to most of us. If it works like it should when your done it’s not dodgy, it’s done and working.

You wouldn't know how impacting your videos have been to me. God bless you in return.

Mia fost de mare ajutor tutorialul tau. Am rezolvat si eu laptopul datorita tie. Mulțumesc maestre

Boss thank you very much for your comprehensive lessons, I am so impressed and learning seriously.

PF101 component is the fuse, its marking "L" means 7A/24V. The next component PL101 is actually the ferrite bead type HCB2012KF. Both inpot MOSFETs are N-CHANNEL.

Sorin you don’t know about your work, how holy work you are doing , you have changed my life, i had studied 3 years electronic but i have scared to open a laptop or any electronic device when I started to watch your video i can able repair the things, thank you sir, hats off

Happy new year Sorin ....Good to see you back :)

All the best for you and your family in 2020! Any video from you is always welcome. Looking forward to your next upload. Greetings from Japan.

Happy new year to you and your family. Thanks for your informative and entertaining videos

Same problem with a Lenovo idea pad 500s, I don’t solved yet,my opinion Bad battery. I hope will be a part 2 of this repair. La multi ani domnu Sorin!!

Welcome back Sorin and Happy new year!!!

Happy new year Big Boss. I love this man. Every day i pray to God to give him long long.

have a good day sorin...best teacher here in youtube academy...thank you very much i learn alot from you

Tq very much Mr. Sorin I've always watch your video and learn new things everyday God bless 🙏 from malaysia

Thank you. And i wish you happy new year!

Happy New Year Sorin!!! Keep up the good work!

This video is extremely helpful. I am having this same problem with a Dell Precision M3800 that I am working on. Customer had a damaged charging port, and a bad internal battery. Replaced both and the laptop ran for the rest of the day but I did not realize it was not charging. The battery icon on the task bar showed it was charging but it really wasn't. The laptop was just running off the pre-charged battery. When it finally died I had no clue why it wasn't charging with a new port and new battery. The symptoms I am experiencing is very similar to this case. No power, not charging, not coming on.

hello sir, you are my first teacher on laptop chip level repair and im always grateful to you for sharing your knowledge 🙂, pls dont get me wrong but this is 90% charging IC problem, because the gate of that first mosfet is connected directly to the charging IC..may God bless u more 🥰😍😇☝🏽🙏🏽

Am gasit acest canal de youtube de o saptamana si vreau sa va felicit pentru ceea ce faceti.

Happy new year sorin! I'm happy you are back!

Happy New Year to you and your family, Mr Sorin. Watched a lot of your video's and learned a lot. Practical info and solutions when you don't have spare parts. I'am not a pro. I simply want to learn things in a practical way. Thanks for chearing you knowlidge. Sorry for my bad english writing. Looking forward to the next video.

Happy New year Sorin, I like you anyway dodgy or not, I watch any video, it gives me the courage to go on and not give up that easy.

Happy new year, Sir. We love your videos.

Welcome Sorin!! And have a happy and nice new year!!

The discord channel is a high quality channel. So many active users with good admins/mods and high knowledge. Very rare to find a server like this.

Yes really amazing, I thought there were no people trying to help in return for nothing. Personally I am totally grateful to all who are part of this Discord family because it has really changed my life. I have been having difficulties with depression and since the moment I registered on the Discord channel my life has changed and I have stopped thinking about bad things. I want to wish you the best of luck in the world and give thanks to people of good heart. I have a blog where I post much more organized material from study material, engineering, mathematics, electronics, schematics etc. A hug to all of you.

2020 the Great Sorin is back YEAA!!😊 Sorin: you are a professional!!! please dont change, the world is plenty of bad changes

Happy New Year Master Sorin and family!

Good to see you back. Have a great year!

Happy New Year, Sorin... 😉✌️

Happy New Year Sorin, and you Family.

you are great teacher thanks for your teachings

Happy new year Sorin! In my experience the controller of those two mosfet from charging input is the charging ic. you can check with a multimeter.

Happy new year sorin.😊 welcome back.

Short cuts are great, they save time and money. Happy New year to you and your family.

Happy New Year! Nice to see you.

I like the way you think - its a practical real world take on repair. Keep going !

Your video made my laptop starts thanx sir

Yo Sorin. Happy new year. Like your way fixing things. Learned from you. btw what is your background into electronics?

Happy New Year to you Sorin.

Welcome back and happy new year for all

Happy new year!..greetings here from Philippines

Happy new year Sorin the only reason i watch you is because your dodgy ;) don't try and be something your not for the trolls have a great day

Sorin, the exact day you promised to yourself: "this year... no dodgy things" !!!! Oh my! A nice way to begin! Anyway, thanks Sorin for sharing & please keep on the great job!

Happy new year Sorin !!!

Credits to this, I was able to solve my problem. Thank you so much!!

Happy New Year to you and your family

Mr.sorin thank you ive learned so much from you

Thank you so much, I just repaired one like this. Like + Subscribed. That's the perfect fuse, yeah? So actually the people are saying when you are able to do bridges with a solder wire your solder skills reach some level. That's fine.

Happy New Year Boss!!

Hey Mr, Sórin...welcome back

Thank's so much, this help me to find the way to fix my laptop !!

The manufacturer does not want you to repair it. That is why they have priority chips installed. They don't have to publish the pinouts. They would rather have you return it to them for repair or purchase a new unit, Because of this you are forced to develop ways to work around the problem (be dodgy??). As you develop these repair methods you increase your value to the customer (and employer). You should never have to apologize for your knowledge or work ethic.

La multi ani Sorin! Este interesant metoda cum cauti o problema, cu benzina, cu brute force, :-) Ca la noi acasa, si cu rezultat. Asa mai departe!

This is amazing thank u so much sir

welcome back and happy new year

Just wondering if problem is at the battery charging circuit ie not switching on the battery charging current like bms fault with cells that are of different charge states (not balanced). but it thinks it is charging

Happy New Year!

Happy new year Sorin.

Sorin you are great at fixing things by your wits thats why we love your channel. Complainers are loosers.

WElcome back in 2020 master sorin

Very helpful thank you!

Hope you had a good new year.

Toate cele bune in noul an! Continua ceea ce faci si nu schimba nimic pentru ca asta ne place la tine. Iti multumesc mult pentru efortul tau de a invata si pe altii. Tot respectul!

Happy new year sir !

Happy New Yeat Sorin. Love your posts and don't wporry about the dodgy posts. I also run my own business and like you said from a business point of view, no schematics, ic data, you face a choice most of the time, time it or give it back unfixed. Keep up the excellent videos !!!

Nice setup Sorin, Can you tell me what camera / gear you are using for your overhead video feed? it looks great.

Nice new to u enjoy all past vids and ready for 2020 from west Virginia I. USA

u are the best sir..,and so humble..god bless u always

Can you tell me what camera and lens system you use on your microscope please as the one I have, even with the 0.5 reduction lens, has a very small field of view on the camera output, so small that a SOP8 package would take up the entire screen.

Happy New Year! 👍😀

2020 have great New Year Sorin..

I have 2 laptops with a similar problem. I would love to see you actually troubleshoot the issue to understand that part. Is it always the charging chip, or can it be a mosfet there too? I have an Asus and a Toshiba with a similar issue : new battery, plugin sign (does not mean charging, it will show when logged in) but battery not charging. Laptop works from battery ,starts from it too. Schematics are usually findable, but still, how to troubleshoot? I saw another channel showing the use of a oscilloscope to check the data lines of the battery to if it had a sane signal. Will try that route first, because there it was a bad mosfet on the charging power supply I think. thanks for sharing!

Happy every single day for you, The Walking Legend :)

thanks for your effort, and happy new year, i think LVS0287kb is SuperIO Chip (KB) and i think the problem in changing circuit !

Hey Sorin, thank you so much for your efforts in producing content, that actually makes a difference - but one whish keeps popping up every time your mic transmitts screaches, cracking sounds and what not - please invest in some new peace of tec - for your followers and fans sake - thank you again for this awesome databse and your lectures- have a nice week!

Dear sir I am from srilanka. I got many ideas and experience from your vedio. I dont know how to thanks to you. Plese.let me know how to rectify screen or cable problem.. You are the one no.1 best teacher for computer ... Thanks ,thanks ,thanks (Sory for my pour english)

Hi Sorin! Love your videos! I have been devouring your videos for hours a day lately, mostly because my predator 17 laptop is on the fritz. I wanted to ask you a question, but i understand beginners asking you questions can be pretty frustrating. i'll ask anyway, because i havent come across a video yet that shows me exactly what fault to look for. so my laptop will sometimes boot, and sometimes wont. when it does boot it freezes in usually 5 minutes where i have to hard shutdown. it used to take like and hour before it froze and it would boot back up, but not really anymore. so i went and multimetered the board and after a few days i have noticed that a couple of mosfets are reading 30v+. should i be looking for bad capacitors, bad mosfets, or bad transistors? should i concentrate on chips? (im clueless on a lot of this stuff but im trying to learn) your insight would be much appreciated or anyone who reads this and knows their stuff. it seems obvious that 2 19v rails are shorting somewhere, but i dont know which components are the likely cause. thanks everyone, and thanks for your awesome instructional content!

Happy New Year 2020 dear!

Happys new year Sorin, could you check from where is first mosfet is power up with(useing diode mode maybe) and see if that chip is power on, then see if secound mosftet is also connected to same chip
