"Monday!"

It takes a lot of character to laugh at yourself - just makes me like your videos even more.

You are not failing you are learning and in the same time teaching all of us. Thank you.

Thanks Sorin! By watching this video, I learned there are some laptops that have charger detection circuit on charging port. Without shorting the detection pin to ground, they don't charge the battery. I'll keep that in my mind for future repairs.

I truly believe learning from making mistakes is the most powerful way to learn. Thanks for all you do Sorin. I have learned a tremendous amount from watching your videos!

Hahaha yes I knew that was the issue. I spent much time on it before.

What was the solution please?

this kinda video make 1 hour feel like 10minute😤packed with information . love it!!

Awkward...hell no. This is a learning experience for many of us so no harm, nothing to be embarrassed about. WE are always learning, especially in this field that is constantly changing. No different than learning to code. WE can't be good all the time, none of us is perfect but I can say I am grateful for this and all the other videos you do - they are honest. Thank you for this lesson.

Agreed. But I can see how arrogance from extensive experience can play a cruel joke on any pro.

I am from Iran and I just met you, I love you very much 🤗

No nonsense. You did a great job. This kind of oversight happens from time to time. You learned something, I learned something. So mission accomplished. ;-)

I followed the troubleshoot with great interest. It so was to my workbench, a sequencer (unit) power fault. In the end, the unit went to dust bin, as a curious fault. Very much a parallel, power on fault in the end where I failed. So at test, I could learn about the 2nd ground as sense. And the care needed to fully test mosfet. 1, 2 or more in design. While a difference in power supply value, the needed approach to troubleshoot important and vital. While I at my bench repair for simple enjoyment of task....not paid..I very much like the repair task, you see. And will try that venture to any model, any laptop or phone. So it is I watch with care the methods used. I gain from where you draw the schematic and I quite thank you for taking the time to teach. I really enjoy all of the posts....and I bid you fair winds, a fair season. Regards. McGary

Not many of us are good as you are Sorin you are the best my teacher and still we are learning through your good and mistakes keep it up

Thank you for uploading this, it's still informative, also learning for us all. You are still a great teacher, and you admit this was " not a great fix". Thank you Sorin.

I've learned more than ever from these two episodes. Thank you for your time and for share your knowledge! Also thanx to the community for their comments.

learning from master's mistakes, that's great too

Pin 11 of the bq chip drives the mosfet between the batt plus and the main 19v pwr sply: the bq drives that mosfet when there is no adapter detect ACDET pin 6 but there is sufficient voltage provided by the batt on the SRN pin 12. Datasheet states for pin 12: "SRN pin is for battery voltage sensing as well."

I just started out learning electronic repair since my old laptop died and i really want to try to get it fixed, your videos are helping enormously and i am learning quite alot from them! Thanks man!

Nice one. You should celebrate tonight with tuica and sarmale de 1 decembrie. La multi ani!

Been there, Done that, Got the tee shirt. It happens to the best of us. At least you owned up to it on video. Respect to you Sorin.

Asta a fost o lectie dura, dar super folositoare pentru multi! Iti multumim pentru tot ceea ce faci Sorin! ...un tip din Tg.Mures carea invatat f.f.f.f.mult de la tine !

Thank You Sorin again for sharing experience and knowledge! And also thanks for the kpjVideo who commented here and told about charging sensors and two contacts.

Well diagnosed KPJ Video. 👍

Hello from Romania. THX for everything you are doing.

well you definetly made a good thing uploading this video, I would never in a million years would have thought about the damn jack detection... I was betting it would be a faulty resistor on the voltage divider and the BQ chip wasn't detecting the charger voltage making it work with battery alone. Thank you sir for this lesson

nt than learning to code. WE can't be good all the time, none of us is perfect but I can say I am grateful for this and all the other videos you do - they are honest. Thank you for this lesson.

Sorin, you show me a big great lesson to remember :)

So, I learned more about mosfets and the gate driver chip from your experienced troubleshooting. If you had recognized the second ground connection this would not be as useful to my learning. Ever so grateful to be at your elbow so to speak, watching you process and explain these components.

It's good that you read comments they served you well in this case :)

Learned a lot from this video. I appreciate your honesty and time my friend!

this happen me all the time! thank u sorin

Learning with Sorin 😃👏👏

love this video ... we still learning to the end.

Great analytical video. You showed how you analyse the problem.

Our kind of video Sorin... we're learning. 👍🏽👍🏽

Thanks for uploading it. I will now watch for this in the future and would not have. BIG thanks!

Soring, you are the best student to have!

You can spent your whole life searching for a fault that you believe is there, but actually it is not ! Thanks for the lesson....😇 Good entertainment ! 😁

Really useful video, thanks for sharing the experiance!

"Probably another sorin is there making these laptops" XD I just ROFLD there. :) Self irony is the best!

La multi ani Sorin!

Until now I haven't noticed that this charging port has such a stupid feature. I wouldn't have noticed it with this repair either. You can buy a large set of adapters for 10-20€ and always go to work with a suitable adapter. It is no point to spare on this investment if you work with it every day.

Don't sweat it Sorin it was still a good video. And trust me you are not a beginner. Things happen, it's fixed.

thank you for sharing the knowledge with us sorir 🙏🙏.. you are a honest man..

Love watching and learning... It's educative God blessed 🙏🙏

I have run into this too. That the cover of the metal on the charging pin needed to be in and present or your power supply would be inop. Took me a long time too. Grrrrrr!!!!

thank you so much Mr. Sorin interesting problem.

But it was a very good leason for us Thank you master 👍💐

amazing video.it was a very good lesson for us.thenks

Video not wasted, in fact hi-lighted my problem with a new laptop, the charger needed to go in just a fraction further,, for the second contact ,,,,problem solved.. Thank you

We learn something every day!

Cele doua suruburi: - proiectarea matritei pentru partea de jos a carcasei mai simpla ; - realizare matritei de turnare mai simpla; - 1 gram de plastic economie / bucata; - robotul A care monteaza "piulitele" sare doua - mai putin timp / bucata; - programarea robotului A - mai simpla mai rapida; - robotul B care realizeaza asamblarea sare doua suruburi. - programarea robotului B mai simpla mai rapida. - etc. - adauga si eventuale controale de calitate sarite pentru operatia X. .... Deci, un surub mai putin, de fapt, e ceva ...

ohhhhh.my god.great job.you are number one.very strong .i have same problem.and after few days . i say you can solve this problem.thanks alottttttttttttttt.

In manufacturing they look for every cent, because 10c on 1,000,000 products is $100,000. Even when you sign a contract with a company to supply parts, you have to reduce the price 3% per year because they expect that making more items will make it cheaper, ie, the manufacturing setup fee gets paid at the start so it should get cheaper.

15:56 " the battery still charging... Thats crazy... Thats insane..." Funny Sorin moment... Thanks for the lesson Sorin...!

It was a fun as well as educational video. :)thanks

Great video

Wow, actually i learned a lot more.... Thank you for a great vid. I dont even own a laptop but its so interesting.

Learned a lot from these two videos :)) is just experience, nothing to regret, yea, is some time invested in there, but for us, and even for you is a mistake that will never happen again, at least we hope :)))

Bet you remember this one forever. Been down the power supply jack thing on consumer items too. There are so many variations on those barrel plugs. Thickness of the outer diameter and the size of the inner pin etc.

good job mate.

Crazy design on the charging port

We are just human beings and we learn all our lives. Regards👋👋👋👋

Noroc Sorin ! Am intâlnit ceva asemănător cand am schimbat un port de alimentare de la un lenovo Lenovo z70-80 iar in cazul aceluia era o rezistenta conectata intre masa incarcatorului si un pin de pe placa de baza (rezistenta se regasea pe mufa de tip tata al incarcatorului, si al naibi de dificil sa o recuperez fiind incastrata intr-un silicon care se topea mai greu decat plasticul mufei)(ca simptom in lipsa rezistentei respective laptopul nu se incarca corespunzător (mai mult se descarca decat se incarca)) Mult noroc daca intalnesti problema asta la un viitor leptop !!

The power of comunity! Merită acel user aprecierile noastre pentru share! Iar tu Sorin e ca-n fabula cu vulpea și corbul: Dar lecția pe care o-nvățași O fi făcând cât boțul tău de caș!…” Mulțumim pentru video! La mulți ani, române!

You are genius sir.

I am no expert but I always start with simple tests first and move on from there, doesn't always solve the problem but it's somewhere to start.

34:52 i like to See Sorin thinking lol

Everyone's done this sort of thing, you go around the houses to realise later there's a quick route..👍😎

This vid is old now, but to my knowledge this extra pin on DC jack is Power supply ID pin. it should not be shorted to the ground. There is a separate ID chip inside the genuine power supply, telling the motherboard which charger is connected.

we are only human sorin ...the easiest problem is also the hardest sometimes ...

55:20 two videos, second part was almost 1 hour finding a problem and removing components. The problem was the connector design. Niceeee

You guys must not run heat in the shop. Everyone always has their jacket's on. Real efficient troopers. 👍👍👍

La multi ani Sorin

It's only me or anybody else is like me get nervous when test result is same again ?😂

Thanks!

I think it’s better to ground that pin by jumper wire to terminate the problem of totally fit adapter

@SerenoOunce

The sense pin most likely is to prevent arcing within the DC jack. Particularly on a laptop like this with dedicated GPU which draws more current. Also a possibility doing a jumper bypass of the sense pin may prevent the laptop from switching to battery power. May make diags more annoying but it does serve a legitimate purpose.

What about latest 2021 laptops. Are they using data pin with power supply forcing users to buy original replacement when p.s adapter fails?

If the power supply has to be properly connected before the computer switches the port on remotely, what are the chances of arcing and subsequent overheating of the connection? It was probably quite a good idea really.

Sorin You Disturbed the Fault so it got It's mind right and corrected itself automatically lol :-) Jesus Loves You Sorin

you still did good job anyway you know i had a similar problem with laptop charger the one i used was 16v but it suppose to be 19v took me a while to realize no video out and then put the right charger in was good so im a idiot hey !!!

Very good video we learn to much from you, i advice you to get standard charger that come with all pc brands connectors, and cut that cable and link it directlly to your power supply that you can monitor amps. Second, i advice you to add cable usb hdmi usb c usb b to negative psu and nevative multi metter so you dont need to use the negative probe that didconnect all time, and u can use negative clamp for open pcv without usb or hdmi ... So any time you wanna use negative just plug usb or hdmi cable to provide negative connection. Ps i need your help with dump bios for asus gl504gm with the serial number of that dump, i need to edit dump and look for serial number you provide and put mine inside Thanks and keep going have good day Peace

Made mistake like this, now I use my own chargers for working on laptops. Some people use their chargers and power cables to play skip rope or their parrots as chewing toys. Suffer and learn...I mean live and learn...hehe

Few screws dont look like much saving until you calculate how many of these you are manufacturing then shipping (weight), margin, waste ( iron slab that was used in making the said screws), time to screw them in and there is also marketing when trying to "lose weight". But hay, if you dont understand something then you can call it idiotic. /s

Not nonsense video : diagnosing considerations were interesting

I did see the last 20 minutes. And I wasted my time on this hahahahaha there was no fault at all hahahaha . I no the pins are on one Toshiba a was looking and looking……….Sorin thanks I learned something hahaha I don’t know what hahaha do the screws on the … hahaha love you man

Guys, does anyone know what temperature Sorin might have used to remove that chip really fast? It seems that he used more than 400c, right? If someone could help I really appreciate. This channel is one of my favorite, and I am learning a lot. Thank you very much.

awwwwwww!! U R Still the best

That's the best way to learn a lesson. You wont forget it.

You can, NO you cant, you can, NO you cant 😂😂

Hai sa o spun in romaneste! Din acest motiv, cei tineri nu invata nimic!!!! Ar trebui luat de la zero, ce este un tranzistor(bipolar, mos fet., igbt, germaniu), ce inseamna o sursa in comutatie etc!!! Am remarcat, cei ce repara pc si laptop nu sunt in stare sa repare o sursa in comutatie!!! sau un invertor de sudura. (de cele mai multe ori schimba igbt cu galeata)La multi ani ROMANIA!!!!

The sensor connector on charging socket is to indicate that charger has been plugged in.

Maybe you had your mind on other projects Sorin. Like Helium mining antennas etc etc ?

what do you use to bring heat down?

I think every person who does repairs has went down a self made rabbit hole and more than likely more than once Love all your vids thanks for sharing Can't wait till the next vid Hope you have a great one

guys help! i have an HP 15 Laptop, did not want to switch on, diagose ad saw that the 1st mosfert wasn't allowing voltage to pass, so I replaced it. AFTER that when u plug the charger on with the battery inside, the charging led does not turn on, when u remove the battery while pluged in, then charging led come on. when charger plugged in without a battery the charging like comes on nicely and the pc goes on. when charger plugged in with the battery inside , no charging led . what can be the problem?

May want to keep a assortment of replacement barrel connectors on hand for this purpose. Then you can still come in with your bench power supply and monitor current. And less time wasted trying to find a compatible brick.

45:03 what did you meassured with two red probes? :)

Electronic troubleshooting is killing our brain man. thx for sharing this info

Wery nice video.👍🇷🇸❤️
