Sorin you're the most funny electronics teacher there is...😂

25:51 LOL! He's quite smart too! :D

[@sniper5406]

the most beautiful thing about Sorin, when he don't know something he tells us i don't know very simple, not like some others starting with their philosophy

[@electronics416devices.]

Thanks teacher i from Tanzania 🇹🇿🇹🇿🇹🇿🇹🇿🇹🇿

[@diyfixtool830]

Lenovo X1 G8 port replacement I really like all your work, a lot of knowledge

[@Gadgetech84]

It was not working due to choke system on hp and lenovo bussines series laptop when some ic’s like audio or lan ic get little heat these boards are design to cut the supply of the system. Once cool down it starts working. I have fixed these issues so many times common fault on hp elite book series

[@RogerPack]

How do you fix?

[@innocentlukama1287]

sir you are a good eclectics teacher

[@mm0077]

It's called Idiopathic symtoms but its woooorking as Sorin puts it. Happy Sorin, viewers and customer.

[@timecentral3134]

The bios is likely going through it's detection and optimization routine's and waiting for various time-outs, then, if those don't work, reboots with other settings and tries again before it finally finds a set of settings that work. I've seen this many times with laptop's that have been dis-assembled and have had the CMOS battery disconnected for a while. When repair is done and it is expected to turn on... wait... find something else to do... it's surprising how long it can take sometimes. (or at least how long it FEELS like when watching it)

[@marcellipovsky8222]

I think there was still some plux in the USB-C port and you scraped it off by connecting and disconnecting the USB-C meter. I would give the USB-C connector an IPA "bath" 😀

[@tel5857]

Yet another example of your skill. Thank you for sharing with us

[@WRZOOZ]

Those Lenovo laptops do have another usb-c port next to that main one. It is used mostly for docking stations so it looks wierd but is fully working USB-C.

Excellent work I really love this job I am also involved in the same profession🙂

[@UniqueComputer-tx3du]

Nice one 🤝, you're the master!

[@jannahcs]

Nice, thought it has a faulty board too. but I can't explain to myself what's happening, it seems there is a magic occurs. Anyway, the vid is very clear and informative. Thanks for uploading your work.😊

[@AbdulMajeedHamid]

Hmmm I just had similar hustle today. Lenovo 2015 model. You plug in the charger power led flashers 3 times then stopped. I did some measure of couple of MOSFETs and I saw one behaving abnormal. Removed it plug in the charger fan came on then off then came on again then stopped, cpu getting warm 🥵. I replaced the MOSFET , it when to the old flashing power led story. I got pissed. I removed my MOSFET and put back the old MOSFET and it started working 😞🥱

[@rfr653]

Good job mate 👍

[@jackjohnson-w2s]

"A five minute job." Video runs 30 mins. LOL Favorite part of all of Sorin's videos is the moment when he gets to say "We have pictureeeee !"

[@glenngarcesa8216]

lol

[@nakipelivan4007]

Nice mr sorin perfect

[@abdellatifaitali9094]

the is 2 cappasitors missing in 21:11 minits on video

[@rostomzerrougui]

Lesson learned today: when you check everything and all looks fine, just plug the charger and go grab a cup of coffee and it will start charging 😅

[@masterliu1892]

You can also go to a beautiful sleep.

[@ilikeito]

It's your magic touch Sorin.

[@Gadgetech84]

Thats why you should use kapton tape or heatsink while replacing port on some newer or old business edition laptops.

[@ronlevin2339]

maybe it took for the BIOAS program time to come on. I hate boards like this were everything is soldered to the MB, companies started to copy MacBook's M series, were nothing can be replaced or upgraded.

[@Tribes11]

I hate it too, it was so much better when everything was modular, it's like we're not evolving, but instead devolving, laptops today are more prone to be faulty and repair dangerous and costy than ever before LOL.

[@olexiylavrik]

​@@Tribes11справа лише в ціні. Не всі готові переплачувати 200-300$ за модульність з позолотою на контактах. Інфляція постійно жене ціни вгору а покупці хочуть купувати ноутбук до тисячі доларів все життя.

[@CooLDEaFY4204Me]

Excellent work Sorin… alway enjoy watch your repair work on those electronics device… alway motivation me, I wish I would like work with company or small business do repair here in Kenai Alaska but nobody seem have their motivation like I do for like your kind job… sigh oh well

[@olexiylavrik]

Почати власну справу? Це ж досить просто, особливо в Америці.

[@jaym5938]

Great work! I was hoping the port hadn't been glued down. Curious if the temps you're using are in C's or F's? thank you!

[@justinspiredfallout]

All temps are in C as is generally the case in the UK and Europe.

[@gonedoneggonedoneg9863]

Nice work.... excelent

[@GregM]

Probably the old flux in the replacement charging port. Get some small cleaning swabs that can fit in there and clean the contacts.

[@dimsumguy1]

I think it was a frozen bios, and after power drained on bios, it was able to reset

[@somewaresim]

I can hear him fine

[@pajdko8382]

that hand movements 😂😂😂

[@RVNR2022]

hi sorin, how do you behave when they send you whole motherboards to get spare parts? do you return it or keep it? just curiosity

[@humamalrawi1276]

It is very likely that it will happen in the phone devices. The charging port was wet, so it does not provide power to the device.

[@olexiylavrik]

100% після чистки від флюсу контактів і від бруду всередині нелінуйтесь просушити легким нагрівом залишки спирту

[@opposites-369]

You should have small compressor for colling temperature after replace components.

[@clivewright7778]

The atten st-862d have cooling function

[@opposites-369]

@@clivewright7778 yeah I really agree, but still remain hot, because the element wire not suddenly cool still remain hot

[@miroslavstevic2036]

it is always a good idea to cool it slowly. rapid cooling can cause cracks.

[@Fareke2]

While i was fixing one HP laptop it didnt turn on after i left for lunch and then it worked fine.

[@masterliu1892]

It's so amazing.

[@ryansrepairslk]

Thought it was just my phone. Had to come to the comments to check 😅

[@klwthe3rd]

The Lenovo X1 Carbon 6th gen(8th Gen intel) is a great laptop. I use the same laptop as my daily driver(Windows 11 Pro) but they are know for their Thunderbolt charging ports to go back. The software was faulty and unless you flashed the firmware when it was fairly new, alot of the USB C charging ports burn up. Lenovo replaced a ton of motherboards under warranty but i wonder if that's what happened to this laptop????

[@aziztcf]

Whats the best way to figure out the footprint/part numbers that fit IF you dont have boardview/schematics?

[@YoYoElectroFix]

It was a working board and the flashing light means the charger is not powerful or the type of the type C cable

[@camarasberta9498]

So what's The melting temperature for The plastic inside the uSB port?

[@Arvidje]

340

[@andrewverran3498]

Lol, those shocking solder blobs on that spare board look like ball bearings..

[@MrSpirit99]

Some oxydation on one of the pins or something else that didn't belong?

[@Stabio_PL]

*Mybe one of the component next to the charging port was too hot after hot air and need time to cooldown?*

[@scottstewart6800]

Rookie question...i know I can probably google it but wanted to heear from the masters...are the temperatures F or C...i have a rework station that goes up to 890 and even all the way up at half power its terribly difficult to loosen chips...perhaps its the Air conditioning in my office???

[@therealbinchicken]

C, the solder they use is crazy resistant, my station only goes to 380c

[@corel965]

It is sim slot not SD card, so you can use mobile internet :) it is business class laptop

[@EsportsTVs]

maybe it was due to the high temperature of some ic close to the usb c port when it cooled down it started charging

[@orion310591RS]

24:20 - I see only Sorin on screen... nothing else looks dodgy xD

[@masterliu1892]

Guys, I want to ask, what should I pay attention to if I travel abroad?

[@justinspiredfallout]

Using USB C as the only socket for charging on a ThinkPad... What were they Thinking? :(

[@olexiylavrik]

Це вже стандарт. Особливо для тонкик пристроїв

[@jamesthomas2417]

Hi Sorin never mind the ducks you thought you had sold a pup AH AH

[@Abdallah.795]

I worked one time on the same laptop and I've never worked again on these type of laptops they drive me crazy

[@klwthe3rd]

Why did you use 400 degrees to remove the charging port on the original board but only 325 degrees on the spare motherboard? If melting the plastic was an issue why did you use 400 degrees on the original motherboard?

[@jeremylaidman6525]

heat+time=melting But hotter means quicker, so less time for heat to reach the plastic

[@olexiylavrik]

400 градусів прискорюють демонтаж. Пластик плавиться і йде на сміття. 340 - пластик не втрачає форми у новій деталі.

[@HexMarksthespot]

He's using 400 to remove the bad charging port so it will get hot fast, melting the solder quickly which means less time heating the board which protects the board. He doesn't care about melting the plastic in the port because he isn't reusing that port. He's using a lower temperature on the spare motherboard because he needs that plastic not to be damaged because he will be reusing that port, and is not concerned about that board since it's a donor board.

[@alantorrance6153]

You removed the port from the board, but omitted to remove solder from the retaining lugs. Would have been a good idea to remove excess solder even before removing the bad port. Then clean all the terminals on the board with new good solder. The replacement socket should likewise have been cleaned so that lumps of solder do not make fitting dubious. Then, once you have set the replacement in place without obstruction of solder on the fixing lugs so that it sits fully down on the proper set of contacts, you should then, and only then, add some solder to the retaining lugs. Of course, if you had thoughts that flux was set inside the socket, this flux should have been scraped out before you attempted to solder it in place. You could then see if the internal contacts on the socket were damaged -- before attempting to solder it. If you follow all these steps, you can save yourself a lot of pain, sorrow, and wasted time. You may actually need to get a brand-new socket. Better luck next time!

[@f1remandg]

I think that you are being very liberal with your comments, however I respect your comments regarding the old engine, I had a friend in the 60s who had a Austin A 35 car and when we came out of the snooker club he would go to start, it would not, and of course we would start to complain and make comments, Chris would say,hey stop now and talk to it, he would put the starting handle in the front and this is the weird part the more derogatory comments that were said, the longer it took, incredible but true. But I think the owner of this laptop has or someone has been messing about with it and your removal of parts and comments, verify that the owner hasn’t been completely honest. Great thing is you are and it also educate someone and show procedures, like the gauge or component that you placed in the charging lead? What is that?

[@Skarz289]

Maby the customer tryed to take loose the port himself on the board he sent you as spare ;)

[@k1mgy]

So, what was the fault?

I think the motherboard needed some how to cool down first

Коли чистите плату і порт всередині - ВИСУШІТЬ спирт. І для тип с чистіть також і штекер, а не тільки гніздо. Це вбереже вас від фантастичних пошуків незрозуміло чого.

I don't get it, you tested those coils. You get 7 Ohms, good. Then you get 18 Ohms, good, then you get 80+ Ohms, also good. And then you get an OL from another coil, and you say it's.. good? So when is a coil bad? What kind of Ohm value do you associate with a BAD coil?

[@electronicsrepairschool]

The coils are never bad, never found a bad coil, what i'm checking is the resistance of the circuit of the coils!
