You are so honest on the repairs Sorin even what they charge and what they cost - highly appreciated and respect your contributions to the community - take care

[@johnholmes1401]

I bought the same kit a month ago and would love to have some guidance and videos for me and the kids to follow along with. You sir are brilliant and treasured for the knowledge you freely distribute.

[@tinkmarshino]

Sorin I will be 70 in two years and I got that same idea last winter.. (I needed something to do in the winter time it is to cold to go outside in the shop..) But it is hard to do it myself.. It is hard for me to remember and I find that I can not stay motivated.. so this would be good for you to do this.. It might help me get to where I understand it enough to light a fire to help me get further.. I have arduinos, raspberry pies, esp32s and a few other things.. So I am ready.. If you want to do this on air..

[@Lifeless11111]

I learned so much from you sorin ,I have repaired many motherboards , consoles ETC. please dont stop making videos, you are a great teacher for beginners but even me i learn stuff sometimes.

[@LIONJCOMPUTERSOLUTIONS]

Thanks for everything sir I personally appreciate honestly because I have learnt many skills from you....I can now repair power pack and monitor even TVs you have been a savior to my life thanks a lot.

[@MilekaRobot]

Finally, one hour+ video :D Works like a cure to me ;)

[@rogerwale4827]

Hi Sorin Even under the microscope these components are tiny, even the probes & tools look massive by comparison, it is any. wonder that occasionally mistakes are made. The honest thing to do was to leave it in. Thats why we love you....

[@KeithPotts]

Thank you to your videos they have gave me confidence to test and change stuff on the board and my laptop now works perfectly keep up the good work

[@reg2590]

For stripping small wires, try gripping the wire in the end of a small crocodile clip and pull! - found this tip on the web somewhere; works for me.

[@nileshindulkar295]

Hello there, my lenovo G50-45 laptop is also facing same problem. I have reset Bios battery but still my laptop not coming on. Also I would like to tell you Soren that there is sparking happening when I try to insert laptop battery between terminals of battery & laptop. Power supply is all good. You should have shown clearly how to bridge MOSFET. This are corona pandemic times. Your videos are welcome, to those who have solved their problems by watching your video. Carry on great work. Kindly let me know video for bridging MOSFET & what tools are needed. Thanks a lot from India 🇮🇳. 🙏🙏🙏

[@blagzster6255]

Definitely up for the Arduino vids. Like you, I'm a hardware guy and I'd love to learn the basics of that crazy strange software stuff.

[@jonsparano6937]

From one old Electronics hardware guy to another, Arduino is a blast! I just got a sensor kit from the same company through Amazon

[@lucianmihai7895]

Apeciate you, onest genuane guy, grate brain, big passion and a lot of knowledge, an example for many, Keep going and thanks!

[@LaptopDisassembly]

I thought i was the only one, that have self-decomposing laptops that are coming for board repair. You fix one thing, and 3 more are falling apart.

[@NomNomNom1989]

Ive done many laptop repairs while I was studying electronic engineering and man I can say for sure that the whole laptop industry should be sued. How can they get away since years with planned obsolescence and no one says anything about it? cheap HDMI ports, cheap charging ports, bad soldering, capacitors flying around in the laptop, horrible cooling, thats everything which could be fixed really easily but they want the laptop to fall apart within 2 years.

[@DanDoucet101]

Yes I'm interested in Arduino. I got this exact kit last year and have gone through some of the tutorials. I found Elegoo's kit to be quite good. Really enjoying your videos

[@azersamaali2016]

I'm not sure but ,if anyone else trying to find out consumer electronics repair try Saankramer Electronic Magazine System (should be on google have a look ) ? Ive heard some interesting things about it and my m8 got excellent results with it.

[@tachidatumoto6016]

@@azersamaali2016 who care.

[@ReparadorAficionado]

Back in the day I ordered a complete kit for Arduino called Tinker kit, from the UK to Mexico. It had all kinds of sensors and the electronic boards were top quality. I recommend you those.

[@zyxnull]

YES SORIN!!!, Please do some videos on micro controllers, I've bought a LOT of this things and they are always fun to play with

[@donniedarko7891]

for this used stuff you have to be a master in repairing. i like your channel

[@kriswillems5661]

What's the function of the second mosfet you've bridged? Only current limiting? Why did it blow?

[@asiqraja4904]

I love watching your videos and can learn. My country is Bangladesh. I am watching from Bangladesh

[@divingbike]

Pls follow up with the repair of the charging circuit and make a video on it!! I had the exact same problem where I bridget the mosfet to fix a dead laptop, as you did, and the notebook was on again but not charging. I changed also the charge IC after removing the bridge but nope, without bridge on the mosfet the notebook was dead again. So I'm really interested to know how you will fix it. Thanks in advance Sorin. ciao from Italy!

[@andreasreimer3929]

Have the same issue on a Toshiba satellite

[@Mr.Smith_Mr.Wesson_andMe]

And exchanging the bridged MOSFET with a new one won't help?

[@divingbike]

@@Mr.Smith_Mr.Wesson_andMe nope. Notebook with a new mosfet was still dead. Only way to let him start was bridge it. But battery was not charging

[@gaborpapa1515]

I had the same issue on an Asus X555. The solution was replacing the first mosfet! After that everything was fine.

[@divingbike]

@@gaborpapa1515 ahhh...maybe that is the key. If it will happen to me again I will try

[@Dr.muthanna]

An interesting video in tracking a serial issues Thank you Sorin

[@doatkormoa9533]

Man you're cool I like your video, very informative and detailed Im putting you on my adblock whitelist

[@stevenpates3791]

I really like your videos, thank you for taking the time to do these because you really help people.

[@user-di1tf4lm2j]

Micro controller programming can be fun when it's in machine code and not in C, gives you a hardware level coding experience. I think you'll be surprised how many kits are available nowadays usually programmable in C. I2c Bus programming.

[@veccloud1573]

Hi Master Sorin, (HeHe.. it sounds so Japanese 😀😀)... We all learn while doing mistakes. Only when you accept your mistakes, you learn, and become great, and that's you. You are just awesome... Just a doubt.. you have shown us many times how to get back those 19v rail. But what if you have 19v is all over the board but still no 3.2v, 5v, 1.5v etc.. You said they come via a power management chip. A tutorial about that would be very helpful.. Thank you Master Sorin

[@wayneharvett6170]

Please video the charge circuit repair. There is very little on the internet addressing charge circuit troubleshooting. Thanks. Your videos are great.

[@catalinconstantinescu3888]

super tare ideea cu focus by arduino :)). Este buna chiar si pentru aparatele care au autofocus, fiinca pe intuneric sau pe seara daca vrei sa pui focusul pe ceva intunecat este posibil sa nu reuseasca ...exista excepti in functie de aparat dar oricum ideea este interesanta. Partea dificila dupa parerea mea ar fi sa iti dai seama unde din cadru a facut focusul, adica daca este o poza de portret caz in care umpli cadru cu o persoana atunci da te-ai putea folosi de senzorul ultrasonic sa iti spuna distanta pana la primul obiect... Problema apare cand vrei sa pui focusul la o alta adancime nu neaparat cel mai apropiat obiect, sar putea sa mearga daca poti avea un unghi foarte mic in care masoara senzorul asfel sa il poti orienta in diferite locuri din raza cadru

[@therzook]

With arduino to learn something, forget any silly notepads or anything like that, go through tutorials and so called sketches already in arduino software. Make sure that your first projects are dumb, literally dumb as there is some boring lot in the beginning, which you have to go through. Once you go through boring stupid stuff (it took me like 8 hrs coz it is really, really boriing), make your first project by pasting few bits of codes from ready sketches. Then you can start bigger things. My first useful project was RS232 monitoring tool - as I do some work on industrial PLC's serial standards 232 and 485 are used a lot in legacy stuff... Very useful this little thing is!

[@VerifyIT]

Love how you explain everything. I am also interested to learn Arduino with you. Already have a similar kit as well. Best wishes!

[@mauanderuk]

Part 2 finishes breakfast.

[@RudolfXC]

No matter what your opinion, you should always return a laptop to the state when new, so replace any faulty components instead of removing a Zener or shorting out a MOSFET. Also, using solder containing lead has been banned in Europe since 2006 and I would be severely desciplined at work if I used it for repairs.

[@loayabbas2454]

nice job Sorin😉 . just replace the second mosfet and will be chrarge agian 👍

[@ciprianpeica85]

when I saw the negative terminal also broken 🤣🤣🤣

[@kiwuzopaul8341]

Nice one I like to learn ic programing

[@yehtut3209]

many thanks, sir.

[@petartomic9783]

And i think from my expirience in programing ,beacuse i didn't know how to program at all and i was really bad at it ,it is a way of thinking and remebering ,it's like when you get to start writing your head switches to programing thinking.

[@Snowbag1998]

40:30 I got my answer. Thank you Sorin !

[@xpanza]

Hi Sorin, you can try to delete everything in battery section from device manager (Microsoft acpi....) That should wake your laptop to charge.

[@xpanza]

after restart

[@obasicomedy]

Thanks for ur very best videos but am interested

[@soeoo4659]

Very good work I like

[@colinblakemore58]

Also would be interested in the Arduino videos. I am an experienced programmer but would like to have a go at programming one of these projects...

[@ohmware2020]

im excited with that arduino project sorin... combination of hardware and software... programming a hardware to work the way it should...

[@alenapatterson1431]

Input and output pins

[@bouxesas2046]

Sorin the sesame seeds from the bagel you were eating on the previous video probably shorted the power management chip. It's ok, it can happen to anyone.

[@herrlip72]

I want to see you used low melts, it's amazing

[@seraj98srour]

Please teach us how to build a soldering station with arduino, and lcd.

[@seancurran1938]

A microchip that blows up. Amazing, possibilities are endless.

[@liveuk]

We have to do Lenovo training online then we qualify as partners. This then gives us full access to parts and schematics without buying copy illegal chips.

Thank you M.r

[@lookatmepleasesir]

the romanian people deserve so much more

[@digihorse6730]

Sorin. I'm a little behind on the videos, so only just heard about your interest in Arduino. I'm also trying to learn. Here's a project idea. What about a solar tracker for your solar panels so the panel moves to track the Suns movement for optimum charge rate?

[@sanjayaabeygunarathna1990]

Dear Mr. Sorin laptop on just goes off but no shorts . please let us know how diagnosis through the videos your earliest respond is highly appreciated. thank you.

[@colinblakemore58]

What is the clear gel flux that you use in instances like this? I use your "home made" Rosin flux most of the time, but this clear flux you used here seems to be better for this type of job; I've looked but they all seem to be coloured rather than clear! Thanks. BTW., I've been watching your videos (all the way through, not 7 minutes! :-)) for the past three years; I think I've just about watched every one! I have learnt so much from you, so I would like to thank you for that. :-)

[@PaoloDiSciorio]

You have nice tweezers....please tell me where I can buy. Tks

[@thulinp]

Arduino is more fun (to me) when you can make something useful, and also something hard to make with just chips. Like a remote control receiver. I added a remote control volume and mute for my 1970s stereo. You can use nearly any old junk remote. Add an IR receiver and digital volume control chip.

[@The_Nirmal]

Where is your shop i need to repair my laptop from you only you pls reply

[@marcellipovsky8222]

Ouch, my back opening cramped when I saw the board laying on the tweezers while Sorin was trying to power it on. 😢😢😢

[@ciprianpeica85]

We already know programming 🤣 but we want to see you do it.

[@emilianoortiz8795]

Hi I was watching your videos and saw something curious. Why does the Asus Vivobook with Radeon Graphics had like a plastic layer on the motherboard? Is it to prevent water damage or to other use.

[@bblod4896]

You left the shorted mosfet in place. Doesn't it protect the rest of the computer in case of a large current draw from defective components?

[@bestbuildpc]

Where did you buy that electric screwdriver Maestro?

[@OverlandOne]

Another awesome video. Thank you.

where you gonna get it fixed at?

[@yellowww21]

Hi, my laptop is a HP pavillion DV6. The laptop has no power yet, the charging light for 19V is on. I tested the bios chip and the 3.3V is present. When i shorted the first two pins of the power adapter, the fans of the laptop turns on yet there is not display in the screen. But when I connected the ribbon cable of the power button, there's no response when this is pressed. Tried reseating the RAM just like your previous videos, this did not fixed anything. Can you help me with this?

[@Keythong]

I'm due for a new laptop soon, my current Dell is 6 years old and showing it's age. I think I'll give Lenovo a swerve, but should I get another dell, or choose a different brand next time? Any recommendations?

Sir please make a video on smd NTC thermister and how to test it with multi meter...samsung mobile always have charging temperature issue...please help.... There are soo many NTC thermister soo its very confusing which to order.

[@fendularatsq2317]

I saw a huge spark when you shorted second mosfet the first time, maybe that messed it up and now its only one way?

How long the silicon hinges last? Has any of them came back for warranty?
