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!
the chip name is this LVS02897KB not LV5 :)
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.
What power supply did you buy?
@@rsapodaca3 it just needs to be a linear power supply, I'm using a switching power supply the so called rockseed rs305p but you can also use a switching power supply
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.
same did this way and all is og thank to yoy Mr sorin
Doing jobs with your "doggy" way meaning you are a professional .Happy new year Sorin ,never change your style !
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.
@ let's not forget that "correct way" also fail, nobody ever bring working laptop to be fixed.
it is already awesome to bring to life a non working board, consider the work under pressure thinking that if it takes too much time to get the job done that will be zero profit for the shop, and since the shop is probably not Apple Inc. even half an hour matters. I think it's beautiful how he can revive a dead laptop in just an hour and then be ready to move on to the next one.
Mia fost de mare ajutor tutorialul tau.
Am rezolvat si eu laptopul datorita tie.
Mulțumesc maestre
Am gasit acest canal de youtube de o saptamana si vreau sa va felicit pentru ceea ce faceti.
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 🥰😍😇☝🏽🙏🏽
Hello, do you have a video on how you checked the charging ic?
You wouldn't know how impacting your videos have been to me. God bless you in return.
have a good day sorin...best teacher here in youtube academy...thank you very much i learn alot from you
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.
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? Is he Romanian? That's cool.
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
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!!
Very Good to see you back. I hope you and your family have a Great Year coming up!
Happy New Year! and thank you for this movie. Another good lesson
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! 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
Happy new year Sorin ....Good to see you back :)
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.
What is the address on the discord channel please? Thanks
@@Vrash87 Hey! It is in the description too: discordapp.com/invite/6zQWaTN
@@Vrash87 Yes - what is the discord channel? - will search now - ICYI - I think it is under "Electronics Repair School" and i was able to add the server. Perhaps Sorin can add the link in furture video's . Cheers!
you are great teacher thanks for your teachings
Don't be sad, I have a little while watching your channel, and I loved it
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.
Tq very much Mr. Sorin I've always watch your video and learn new things everyday God bless 🙏 from malaysia
La multi ani, Sorin! Bine ai revenit!
E bine să fii sincer:)) Faci o treabă foarte bună pentru îvățăcei!
Sorin is the best teacher ever ..ur getting old just bcoz of our benefits..😥thanks alot and God bless u Mr
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.
Yessss !! What counts is effectiveness
Your video made my laptop starts thanx sir
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.
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.
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!
I respect your choice ,but what about the dodgy Friday (you can collect Jobs during the week and start every video with "finally Friday" ) .Just think about ;)
please Sorin,have a look at this comment
Yeah dodgy Friday would be a great idea.
seen it first :P
@@electronicsrepairschool haha i just watched video. No dodgy friday, dodgy everyday :D
From "shop" point of view you are correct. You do not have a lot of time to spare on each laptop or phone.I have also a shop and I feel the same. Sadly or not we do have to make make money to keep moving and if a job takes a lot of time we have to give up some times and move on. From user's point of view it is a diffent story.
Στέλιος Τζαννής What do you tell your customers when you give the laptop back with no fix an maybe with further damages? I find this hard to deal with in such cases .
@@ictrepairs6963 If fix not possible, I say I cannot fix it. If I need 10 hours to repair it, I say I need 10hours x 50€/hour = 500€, so better buy a new laptop. No further damages are done when I diagnose a laptop.
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.
How did you repair yours? I am having the same issue with my lenovo 1570
@@RiMz1876 just doing what video shows/explains.
Sorin you are great at fixing things by your wits thats why we love your channel. Complainers are loosers.
27 minutes in - new years resolution - down the pan lol Happy new year Sorin try resetting bios thats a known lenovo issue.
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.
2020 the Great Sorin is back YEAA!!😊
Sorin: you are a professional!!! please dont change, the world is plenty of bad changes
Welcome back Sorin and Happy new year!!!
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.
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!
Boss thank you very much for your comprehensive lessons, I am so impressed and learning seriously.

Happy new year to you and your family. Thanks for your informative and entertaining videos
Happy New Year Sorin!!! Keep up the good work!
Board NM--B301 have BQ24780 which drives the gate in this mosfet PQ311. This BQ has ACDET pin which voltage should be present on the gate PQ311. As a lesson the video is great, but the device shouldn't be taken out to the client because it could be make better. Don't forget of it Master. Still the best channel on youtube in learning the electronics! Greetings Sorin! :)
Hello, then what is the main problem? I have the BQ24780s, is it the main problem?
Hey Mr, Sórin...welcome back
Short cuts are great, they save time and money. Happy New year to you and your family.
happy new year ........
your are the BOSS of all PRO
keep uploading videos everyday this year
Happy new year , happy to see you again.
“Lets make a bridge and end of story” XD
Good to see you back. Have a great year!
Happy new year sorin! I'm happy you are back!
Hi, I would try the second mosfet for a short circuit, I had exactly this laptop with the same problem. I bypassed the first mosfet and the laptop worked well, as the second was permanently open (I found out later), but the laptop did not charge. After I replaced the second mosfet, the first one worked as well and the laptop also charged the battery.
really ? that means 2nd MOSFET is the fault?
I thought fault with BQ24780S (PU301) Charging controller IC.
@@whatsappshop3068 That was the problem in my case, it may not always be the case. Some laptops have it solved this way, not all. Sorim also talked about it in one of his videos.
Hello, where exactly is the second mosfet located?
@@ivankay8157 Hi. The second mosfet on the input circuit.
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!
u are the best sir..,and so humble..god bless u always
Welcome Back Mr Sorin.
Me in January 2020: Yeah, I hope this year will turn out great!

hi sorin, i have the ideapad 310 with the exact same fault. both first mosfets are dead and charging led flashes 3 times quickly. i have no idea what the problem is
Thanks sorin your God teacher I like your job from Mozambique South African
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!
The chip is lvs not LV5 easy to mistake. I know 2 1/2 years old. I kept yelling at the screen, but you can't hear😜 Enjoy all your videos. Thank you.
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 !!!
Happy New Year Boss!!
Nice new to u enjoy all past vids and ready for 2020 from west Virginia I. USA
Phew... for a moment I thought we were going to stop being dodgy. That's the best part of the job! 😎
Welcome back mr.sorin
Hope you had a good new year.
Thanks anyway Sorin !
