This is a future of laptops, instead of dealing of 2 screws in round pin charging port, now we need to deal with a soldered 10 pin type-C port, that soldered like in a first year student project
These tutorials never get old or boring
Nice job, I usually use longer wires and solder them to further places like vias. This lowers the probability of breaking connections again
Lucky man always fixes Nice laptops!
He can not believe he has picture at the end!
We have picture, not just him
Mister perfect! Beautiful work !
Your videos are so educational and so much fun to watch. 😊
It's better than factory! 🙂
(I would have added some hotglue to secure the port.)
Alex will block you for using his moto😂
@@Hejazi1365 really? 😂
Every time you have a successful repair you won't believe it and i can't believe 😂😂😂😂. You are a great teacher. Much appreciation
Nice Job Sorin
soldering skills "on another level"
20:41 I love when you say "we have a picture" 🤩
Charging via USB C is design to fail. I am using the same laptop model and was aware of this design fault from day one. For minimizing the risk of ripping the connector I am using an angled connector. It helps a lot as the leverage is much less than a straight connector. For me this works fine since years. I would advice this to all users of USB C charging ports.
How about those magnetic connectors that would release when strained?? I use them on my tablets and love them!
New thermal paste 🤩 ❤ I can’t believe
Thank you for the great troubleshooting!! And great repair! 🤓
They should use a small extension now so they Dont have to plug and unplug from laptop
Even better would be a "Type C Adapter OTG 40Gbps Magnetic". Search it on Google.
Good job mate 👏
that is a proper repair job.
You identify the problem well, Sorin. As soon as we begin a customer relationship, it's there ready to bite. I had a PS5 come back after 6 months of fixing the HDMI port. Of course, the fix should last longer and I've never had port come back so I take it back. Not able to say if was impacted again, but just reflowed it again no questions. Sales even worse, especially refurbished. Every problem the customer has (like not being able to look up stuff online) and another load of support messages come back.
very nice repair i loved 👌👌👌👍❤❤❤❤❤
Nice it was a great one
Ive watched so many of your laptop repair video's that when ever you say "what we checking first" I always say to myself "power rails" and I can easily identify where they are 😁 Love your videos and I always look forward to your next one 🙂
Nice one
LOL - I've never seen a laptop with chocolate damage before!! I remember when laptop power jacks came on a very easy to change cable rather than soldered directly to the board.
Perfect!!!!!!!!
I actually start by disconnecting the battery. Older laptops with batteries that pop off, its a quick way to tell if its the battery or not. its a bit of a hassle now that they are inside, but its often the first thing I try, then I check the power connector.
What size copper wire to fix the charging port? Thanks!
I just realized that sorin, and rosin have all the same letters and only 2 letters are swapped.
epoxy resin copper tape onto the board where the pads were, then you can solder the traces to the copper tape. it will be nearly as strong as new.
Sir sorin you and I have same UV light.
Soketin üstündeki iki tırnak vardı. O tırnakları aşağıya doğru bastırmanız gerekiyordu. Çünkü o tırnaklar soket içindeki plastik pin yuvalarını sabitliyordu. O yüzden o soket en kısa sürede tekrar kırılacak
i prefer the port to be replace... a lasting repair should be on the top list
I am asking myself why Sorin didn’t replace this instead. I love his work.
Guidelines for wire caliberation plz.. 🙂🙂
A bit of your magical hot glue on the back of the usb port will help not no move again to avoid when stick the charger to get back and brake and ripp the pads!
Hi Sorin what is the name of a spray using
nice
You should use some duble glue on the black plastic to keep it not move if you don't use glue it will move and broke again 😅
There is a limit to what repairs can be covered by warranty.Im not sure about the UK legislation but here (southern Europe), i never offer warranty on liquid damage repairs,mechanical damage and pad restoration,such as this broken port,hinge jobs(even though i never had any returns or complaints),normal broken charging ports,hdmi ports etc.Even on simple capacitor short circuits ,what warranty can you provide?After a month, something might break,like a PCH/cpu/gpu.Customer will never believe you if you tell him "ok warranty only on the replacement cap,this time your cpu is burned to a crisp."Customer doesnt know what is a cap or a PCH,customer knows only a dead or a working laptop.So no warranty /money back, only a free 90 day destimate on whatever similar issue.ofc normal warranty on ram memory dimms/ssd.
Sorin can we use USB 3.1 Type C Connector 24+2P Male Female Breakout Board this type of repair?
I think this USB port will fail soon ((. The plastic insert is moving inside the casing, that is the reason of the initial fault. The solution of this problem is to glue on the insert after soldering the broken tracks.
It's Christmas soon😂 The laptop in a festive mood🎉😅!
Suggest you avoid looking at UV light as best you can.
When I saw the dent in the side of the laptop case around where the USB-C port was I knew it was not good.
Hello🤝Perfect👍👍👍👍👏👏👏👏👏👋👋👋👋👋
How did you find the main power rail?
any input caps next to any (but most easily to found next to CPU) power supply.
How i deal with this kind of problems
1 Open laptop and cheak inductors for short.
2nd cheak the power connector health,
3rd solder wire for v-charg in and power it with power supply ''enabling short protect and limit amps
4rth when it start i go back to usb if no i look for the problem maybe short or power key not working so look for 3.3v
If it power i should replace it with fresh new connector, if the connector is not availble i desolder it and try to renforce it with plier
Solder the connector and cheak for shorted pins
Test the connector
Apply solder mask
Apply epoxy glue and be aware from case and otherstuff emplacement, you may have excess of epoxy than the case will not get closed
Close the laptop and say we did great job better than factory
Hello All, There must be a way to explain the customer, if they want a 100% fix, they need a new motherboard. I would only then offer them this repair without any warranty.
I would have added hot glue where it is safe from entering the connector itself
It's crazy it's happened to glued charging port
The whole point of the glue is to avoid this kind of fault
A suggestion - take a vacuum to that fan
That resin is good stuff but in this situation I would have used hot glue :)
Hi, thanks for sharing
I have a Huawei D14 DAH98AMBADO
It is dead and a little 2.5V LDO near USB3 port g’ets very hot. I have a diagram, but i cant find component placement, do you have an idea of what I could try?
I thank I would have removed the fan as a nice jester
Hi Sorin, can it be I mad you in Birmingham on a Samsung course?
❤
I keep saying it: USB-C is not as strong as the industry says it is
i hate usb c
This ones been to Willy Wonka's Chocolate Factory! 🤭 I would REALLY like to know how that chocolate got into that area! 🤣
👌👌👍👍
💕💕
Hi Sorin, i am wondering are you from Romania?
Da, e din Romania.
i would say Proper Chocolate!😅
Hi Sorin, the proper calibrated wires are 0.2 mm? 😂
Using uv mask was so not dodgy. 😅
I have problem. I dont know how to find main power rail. How you know in just one second what is main power rail?
I'm wondering with USB D they will make even smaller weaker connections so they break daily. Who agreed on these fragile usb C standard. crazy cooky stuff.
Judging by the melted chocolate inside, she could be using USB 1.0 or even wires solded to the charging port and still manage to brake the thing apart. But I have to agree, everything it's so fragile this days.
Not enough hot glue 😢
Can Anyone solve my problem
I have replaced my laptop(Dell Inspiron 3511) battery 3 days back and when I opened the laptop yesterday the screen is becoming dull when it is not connected to charger and it shut down suddenly when I run a small code on VS code. It is working fine when kept plugged in. What could be the exact problem can someone answer me ?
Seen in facebook first 😂
proper caliberated wire?WHAT IS THAT?
This is not a proper job sorin, a proper job would be to desolder the connector, rebuild the traces, secure them with mask and use a new connector, or the same connector if it has no problems.
Why don't you change the whole usb-c connector ?
I thought you were going to use hot glue to fix the connector
Flux name please sir
I think the chocolate was shorted 🍫
welcome to the miracle of usb type C.... :))
That is properly calibrated chocolate on the mother board
First!
... to say anything negative?
Sorry Sorin, but you could clearly see that the plastic insert of the USB-C port was loose in its metal sheath, which was still firmly attatched. You did a good job re-connecting the traces, butI bekieve that you should have replaced the port as they are inexpensive.... last year I bought a box of 500 assorted ones for less than £25.
I think that your repair might fail quickly as the only thing holding it together is not the mechanical integrety of the metal surround physically holding the inner blade and the contacts, but the strength of those wires jumped to the traces. For the sake of spending 20p on a connector? C'mon man, I KNOW you can do better :)
why uv gel, why not hot glue
The UV glue can be scraped off, making it easier to repair next time.
@@SangFix you can remove it with acetone, nail polish remover
What? no hot glue? Is it really Sorin?
If they’re going to use USB’s and at that, 1 usb c, could they at least put it on a daughter board that costs $10 to replace.
How can that happen in a laptop that is one year old? I know USB-C chargers are the crappiest invention of Mankind, but one year! Looks like a new income stream for Computer Stores, replacing the connectors. And/or sell those Laptops with a high quality extension to take the stress off the port.
There's a mistake in your comment, you need to remove the words chargers are and replace them with is.
Built not to last
What might cause the damage on a fairly new laptop?
So, what we are checking first? Signs of chocolate, then water, then burnt mosfets (or, when all combined, hot chocolate) obvs, ho, ho
1 I/O should be banned, ie, Mac's sux. Performers always use Mac, and of course with one I/O it wears out quick and ruins the show when it stops working due to bad connections.
I would hot-glue that - lol -.
Proper calibrated wire 😂
Second here
First here
Sorin i know it looks like chocolate but ...
Laptop îs not ok USB C Charging port😂😂😂 it is sensibil port for Charging...
it was poo not chocolate
