After learning about hot glue from Sorin, I have been using it for the last 3 years and I haven't had any job return. Hot glue is just amazing. ✨
watch all of his videos, might take a month or so, but by time you are finished, you will end up teaching your kids a very needed skill. like and share his videos and force your kids to watch his other channels !
Sorin is king of dodgy repairs. I love it.
you see how he did the hinge @ 24:00 mins, he put the glue on the holes, so the heads of the hinge would fit in the holes, then press down, let it bond, then heated up the metal again, then placed more glue on it. Better than factory.
Sir your ideology was very good to understand the diagnosis concept the way you approach the methodology was really awesome A normal technician can't t do in such a way I'm very happy to follow you love to learn good knowledge from you sir thanku
Hot glue is incredibly durable and versatile and has insane hold strength. I even use hot glue with my woodturning lathe
I have successfully done 100s of hinge jobs using hot glue. Sometimes I loosen the nut and lubricate the hinge and those kind of jobs rarely come back.
Thank you very much Sorin and have a good weekend!
nice i learned from previous videos how to find 19v on screen connector
you are right.. i saw couple laptops mostly Dell with glued display frame and also damaged one while removing that frame.. so stupid.. for hinges repair I bought set of brass nuts what manufacturers mold to the plastic frame an I repair broken plastic using ABS fillament for 3D printers and melting it with soldering iron.. its strong as hell after that repair
When applying hot glue to the hinge would it be worth putting some metal foil over the LCD to avoid damage from the heat gun?
i never thought the hot glue was so strong like that
You're hot glue method is the best, use if a few yeas since saw it here its cheap and reliable. Thank you.
Try to find the 3M yellow hot glue...its godly, 10 times stronger than the simple one
I've been using epoxy glue for the hinge problem. I will definitely try using hot glue for hinge repair in the future.
Used epoxy, super glues etc. Hot glue the best solution especially when the screw grommets come off.
ı dont know hot glue doesnt hold sometimes and I screw the screen hinges and put a nut on the back.. that is my solution for strong hinges.
@@seckinseckin3919 I've been using epoxy, So far its ok but never tried hot glue for hinge repair.
23:22 yes it can be. For example when the water or alcohol gets around that hot glue for 30/60seconds it will rip that glue off. (most people remove hotglue by heat, but the better way is to remove it cold after apply alcohol there and wait 1minute) and also when your fixed hinge is close to heatsink/radiator it will break one day. Anyway hot glue is still the best for hinges.
Good tip for removing hor glue.
I use hot glue for hinges since I've Dodgy Sorin using hot glue. I've tried other glues before too messy and weak bond.
I use milliput epoxy putty for 3D prints and it sticks hard plastic like something to a blanket.
Good job mate 👍
Totally respect your decision not to clean the laptop. I like the hot glue hinge fix it makes sense, it's flexible glue and if you get a good bond it's better than any other option available. I have an old HP ProBook 6470b (which flies with Windows 10 as I fitted a decent SSD to it) with a broken hinge which I fixed with epoxy - but it's mine so I know to treat it gently, it's lasted two years so far. But I bet if I was to lend it to someone it would be broke again within a month.
This is a great unit.
I am talking to you from a country where the temperature reaches more than 50 degrees Celsius. Hot glue is effective and is the only solution for hinges. My question is, if hot glue melts in hot climates, why does it not dissolve before using it? I don't remember the day I bought a cylindrical piece of hot glue with half of it in the store
hot glue doesnt hold sometimes and I screw the screen hinges and put a nut on the back.. that is my solution for strong hinges.
@@seckinseckin3919 that solution works with metal back cover
i love when sorin fix laptop and say "what do you think ah " xD
Love this repaires..... L'OL
The video is shorted?
We have peekchure!😊
Sorin the power button cable terminal leg in picture furthest right looks like its gone (pad). Thoug not bring problems maybe. If i would be you i would have tested continuity of it at minimum as so corroded looking one.
Why dont you just replace or schort hte fuse instead of using a wire to feed the voltage to the backlight? it will be much quicker and neater + you are bypassing the fuse either way so no protection for the pch the next time the laptop gets water damaged
Thats what I was about to write as a comment aswell. Not sure what kind of fuse that is or if he has it in stock?
@@x-fix 32V/3A - most common fuse, nearly always the same kind used in Thinkpads
@@x-fixthere is a fuse inside of screen don’t worry
@@4Relax Ah, then its a whole different story! :)
@@verpejas Thanks for the reply! Thats good to know!
Mr. Sorin. Can the Ribbon Cable be replaced ?????????
Will the wire bounce back sir?
Were you using IPA Alcohol (or as it looked sticky) just water to clean it?
The doggy way of fixing the screen connector sometimes will not work. It happened to me after doing so the panel's internal fuse was broken. Maybe the screen was dead and the screen internal power mosfet was already dead.
Also for the cleaning part. The costumer is not your friend or brother or whatever. If he brings a fault ypu just fix that one. I agree 100%. Because even if you do it for charity because you are nice to costumers. Sometime the costumer will tell ypu this dust is belong to my girlfriend's house before she past away and it was the only memory. Then he will sue you.
Hello. Love your videos. I was wondering how l could send my laptop to fix?
❤
Hi Sorin if i semd a laptop Asus the same model issue with motherboard is start logo Asus shoew.and go off .
Good work you are doing @Sorin. Am Stephen from Kenya. Kindly my HP (15-f271wm) charging light flickers when i connect charger and it doesn't power on. How i wish i was close to where you are. What could be the problem? Thank you. May be if you have social media account i can share the video.
You should post your question on his forum, maybe someone will be able to give you some useful tips.
Proper calibrated wire 😂
I have a question Sir Sorin. Has there ever been an Hinge Job you couldn't fix? Just curious sir.
Good day Mr. Sorin
Is it possible use laptop power supply to detect the shorted component and using thermal camera?
Thank you & keep up the good work
you're better off asking on sat or sunday on his live
You can’t as laptop power supply will detect short circuit will go in “short circuit protection mode”. ie stop the output .
Never do it, u can't control current that way u can fry something.
Si puedes. Solo recuerda comenzar con muy poco voltaje o amperaje, ya que como te comentaron ahí podrías freír otra cosa. Inyecta muy poco voltaje o amperaje, y fíjate con la cámara térmica. Y verás el componente en corto sin dañar algo más. Y por favor, no solamente quites el componente en corto, que de por sí quedará andando, por favor reemplazalo por otro, ya sea de una placa de descarte. En los esquemáticos podrás encontrar el mismo componente. Compara esquemáticos y de ahí obtendrás tu repuesto. Espero te sirve mi respuesta. Saludos desde Argentina
Hello🤝great work 👍👍👍👍👏👏👏👏👋👋👋👋👋👋
You like to take short cuts to get something fixed.
I agree with your decision not to clean the laptop.
You work for what you get paid, the broken hinge
please what is the name of the liquid you're using to clean the board.
isopropyl alcohol
lol@@electronicsrepairschool
Link to your screw driver?@@electronicsrepairschool
check link "my tools" in decribsion of video@@SirJelani
Lenovo do some good laptops use to be IBM the Thinkpad.
What time do you wake up Sorin??
Too early :)
yeah ok hot glue its the best and fast way :) with minimal cost to help :)
good i get another video to be a expert
I love your channel and all your great content but this one was a patch not a repair. That’s what’s done to limp it to a proper repair shop.
Why can't the local repair shop fix this - that's why they're in business - but it gives you more work and money
Cleaning with water is good?
If u have liquid with sugar yes, otherwise go with ipa.
Sorin, how's Diana? Will there be more educational vids?😶
i notice your banana plugs are taped all black , could tell us how you manage to push your power from your power supply of your banana plugs that are home made to your choice different tips you always change if you dont mind
reinstalled Win 10 on a lenovo and it ends up and shows a Windows old. why>
Which kind of liquid you used
Alcohol isopropilico (eso dijo él en otro comentario que leí)
Do you know how to repair without thermal camera ?
You can use your fingers, isopropyl alcohol, zippo petrol etc to find shorts.
@@Aneesh.Asokan thank u
@@Aneesh.Asokan btw i have weird problem on my phone its not shorted but doesnt power on idk why
Bye
what?! a lenovo laptop that doesnt have a bios issue that's new
I would never release a repair like this, to my mind this is just a bandage. How much time would it take to find the reason for no power at the backlight circuit. The question really is do you inform your customers that the repair actually changed the layout of power distribution. and was not a one for one repair. In my opinion you do not tell your customers of the repair made. I think your a decent guy who got in the habit of down and dirty repairs. That might of been ok where your from but looked down at where you are.
Dooooodgy 🤣🤣🤣 we love Dodgy
you dont have to explain we know or i do where you coming from on the cleaning part

Sorry this would be ok if it was like Entry point HP but not for u T series Thinkpad... 15minutes + 5 to locate a fuse + another 5 to replace it = 15€ more cause its expensive machine... So "dog like" repair. 🤣😂
I hope this a joke because this laptop is not worth repairing any other way. No one In their right mind would pay big money. You don’t own a repair shop like some of us so you wouldn’t understand.
@@shiftctrlhack Its not realy a joke but i do repairs for like 20 years now and T590 to what i was refering to was like 2300euros ita an expensive and good business machine i personaly own a T480S and if someone did this to my laptop i would be mad... Its a good repair it works but i would never get back after this... You need to know sales in order to understand what kind of people buy this kind of machines.
@@Dragunov1111 I would that to my own equipment .I could never give that to a customer as a repair.
@@AlaskanInsights Yeah thats my opinion to... You can if the customer has no money and its like you warn them before. Better not... Some kid will open it post it on internet and then bye bye customers... Hard version is that you get sued for that...
