You the best. I'm one of your leaner followers and have a special folder just your videos in my laptop. May God bless you. Believe it when I say you helping me feed my family. Best of love from Africa, Botswana
Hi, I am from Argentina, we do a lot of this kind of repairs, laptops here are very expensives, so we repair as much as we can. Thanks for the video! helps a lot!
I notice some people are so rough on their electronics: phones, computers and tablets,. I had my computer for years and my phone for years and they are in very good condition. Good job sorin, you are one of the best on RUclips.
Nice work Sorin! That model HP uses the cheapest plastic I have ever seen. It is very brittle and cracks easily especially where the hinges mount. You have to be VERY careful opening the laptop when the bottom cover is removed because the hinge mounts can snap. If the hinge gets too tight it can also cause the cheap plastic mounts to break. Nothing is made to last anymore.
I am very thankful to you Sorin, Sir for making a video of such a thorough job. It gives me inspiration to venture to work on my Toshiba Satellite Radius P55W-B5224, which has a loose hinge, all vowels of the keyboard do not work, after watching a movie for longer than 1 hour, the screen suddenly started malfunctioning - flickering. I thought it got too hot. I opened the laptop and cleaned the fan blades and then vacuumed the air inlet (tiny holes on the top portion of the keyboard). I reinstalled the display driver and reseated the RAM, battery, touch screen. Screen flickering getting worse to a point that screen getting dim and nothing shows up on the screen. However, I used an external keyboard and external monitor connecting the monitor with a HDMI cable. The external monitor is displaying everything and playing movies perfectly. I do not want to buy a new screen. The laptop's screen was fantastic before trouble started. I have not touched the LCD display cable. However, unplugged the touch screen to reduce interference. I might have made a mistake when I unplugged the touch screen cable - perhaps did not disconnect the battery (disconnected the charger though). Sorin's video gives some hope to identify the connection point(s) of the display cable on the motherboard side as well as on the back of the screen. This model of Toshiba laptop is more complex than other models. Any feedback from viewers as well as from our Professor, Sorin is much appreciated. God Bless you, Sir!! You are really, really good - running short of words to appreciate what you do and your knowledge and mentality - help others and the environment. Thank you for sharing your knowledge and experience!!!
sorin, I really love when you talk about how to run the business, please keep this talking on. we learn from this talking just like from electronic repair.❤️ my appreciation 👏👏👏
Also as a customer I want my lap top working.. if more is needed I want to know before the work is done so I can say yeah or nay.. I hate it when they say your job cost xxx only to come back and find it is now much more than originally planned for.. you did a good job.. I used to own my own business for 40 years.. I know what is needed.. and options are the best way..
Hi; first time I'm writing to you even if I follow you for 4 years. As you, I do have my own shop in France. Repairing hinge is something I do twice a week. But, I do not use hot melt glue anymore because it is not safe enough. What I do is making small holes and put screw. This maintain the hinge with the plastic. Anyway, thanks a lot for sharing your repairs, it help me when i'm stuck on a mother board and, several time, it helped me a lot to fix motherboards .
On vacation i fix up computers and laptops in my village. I often see broken hinges and i tell the customer. We can A. Glue it together but it will likely break agin and it might not be possible, B. Buy a new screen housing but it will definetly break agin or C. Repair it proper solid with a bolt and nut on the other side. They always choose C and never regret.
I applied A (JB Weld two compound mixed thoroughly) and failed miserably - did not stick to the cover of my Toshiba Satellite Radius P55W-B5224 laptop at all. I am ready to apply method C, drill hole on cover, put bolt and nut. However, I am afraid that it may rip off the top cover around the hinge area because the hinge is very tight. I think this model of Toshiba laptop is very complex and may pose a challenge to access to loosen the hinge. This video gives some hope to access and loosen the hinge before putting bolt and nut. Thanks for your post as well as thanks to the author of this video.
indeed a great one kwanza flipping the mosfet to get 19v that was dope..Sorin is saying 20 pound for hidge na huku uambie customer 1500 ana complain. big up man
I appreciate a lot that type of video, good to you to show that sort of situation (even when you go into trouble for some customers, losing time, and there is an accident then, you may face trouble) great to show that repair, thanks This is a hobby for me I admit ; that sort of laptop is relatively easily sold between 60 - 100€ then send away to another country. SO some laptops from the bin get a new life and are useful to someone in the end - after sometime, I get used to old type USB replacement on telephones and other blue tooth devices, thanks to all those videos, does not make me an electronician, but somebody that can help in some case ;)
Thank you SORIN for such teachings and lessons for us to feed more put of your knowledge , keep up the good work and for this generation you are such a blessing unaware but honestly you are a blessing indeed. You dont know how much you are helping people to improve their work in their workshops in all you are leading a big generation to survive, thank Again My Mentor SORIN 🤝
There are shops that wouldn't even touch that job. But you fixed his laptop the best you could. I'm sure he will appreciate it. Not everyone has all kinds of money to spend and you understand that. Always learning from your channel. Thankyou JR
I wouldnt touch that job as customer may blame me when screen components (webcam,microphone etc. ) are not working and i could not check before as it did not power up from beginning . And with warranty you cannot repair this below 150pound, at least not here with strong customer laws.
What I've learned from several repair videos and channels is to always check the second mosfet. If this is shorted, even the first one does not work because of lacking gate-voltage. But anyways, this channel was the starting point of my interest in electronic repairs. I've learned a lot since then and still do. Thanks Sorin.
Exactly, what i found on badcaps forum is the information that the most troubleing thing for the beginners is that the MOSFET that is blocking the current is not the MOSFET that has failed. Usually the problem is shorted second MOSFET.
😍Excellent Repair, Sorin😍 PLEASE stop apologizing for doing great work and fixing broken things. I can tell you have honor, integrity and honesty. When I come to the UK if I can find your shop I will bring my broken things to you without a second thought and 100 percent confidence in your "dodgy" repair.... Much respect for you and your skills.
You are doing a good job Mr repair teacher I love your patience , I love how you are teaching , may God bless you and give you long life , thank you so much for everything
Its nice to see you are ok THANK YOU for what you do and what you teach us. Thank you very much. I hope one day i could help other people with my job. Blessings Sorin.
Sorin i have one little suggestion you should put it title or in description which exactly model of laptop you been working on because many many people search and cant find some and you have that done repaired showed everything but there is no way to find it if you just not lucky to see it on your video. and I think that will increase viewership by ALOTTTTT! for real when people type for example hp g3 repair your video will popup and I think in my head for days and days why you don't put that in description or title it gonna help the world ! Especialy someone godmaster like you in this! Much love from Serbia!
We need more videos like this there are times where ordering a part isn't the easiest or fastest . Here in serbia we don't have an option for cheap and fast shiping of those parts so the only option many times is to order from aliexpress or ebay and wait few months which isn't the optimal solution most of the times if customer needs his device done as soon as posible. And this is great temporary solution for the customer to get it working untill part arives. Thanks for the video!
The price is the most stuck issue in the walet of a customer, when it comes to repair electronics and negociate, because all what you do is just predict an less amount to get the deal and job done good job Sorin and i like the video ';D
Jobul asta mi-a adus aminte o intimplare de acu citiva ani in urma ( nu multi, 4-5 ani ): A venit un om cu o unitate de pc si m-a rugat sa ma ocup de ea ca-l scot copii din casa. I-am zis s-o lase si sa treaca dupa 2 zile. Nu m-am uitat pe loc. Am avut un soc cind am constat ca era un 386SX. In final i-am facut o unitate cu un P4 si i-am dat-o de pomana cu conditia sa duca cealalta unitate la reciclat. PS. Chiar is curios si eu cum vor fi comentariile
Hey Sorin, you have forgot to check the second MosFet. Replacing the second MosFet that was broken here would have been no more work and hardly any more cost.
its not the point of if it was easy to replace. if he didnt charge the customer much and was able to make it work then all is fine. why would you add new parts at your own cost ? you like to give away profit? and to be honest that laptop was not worth even repairing. but he did get it working and usable again. so there is no mistake made here.
@@cptrush3671 We have other opinions. Sorin has enough scrap boards with matching MosFet, but new such a MosFet also costs only 5-10 cents. I'd rather lose 5 cents than return the notebook not working properly. The job ist the same. And I think if he knew these fault, he would have changed it too.
Maybe a missed something there, but why replacing the second mosfet in a case like this one, where the voltage is not passing the first mosfet? I mean, we are replacing a burned component if the component is faulty, but this is not the case as the gate signal is missing from the first mosfet which is a channel n and is supposed to have 19v on the gate
@@electronicsrepairschool If the second Mosfet is shorted, CMSRC (ACDRV charge pump source input) will also be shorted to ACP (Input current sense resistor positive input), the BQ-IC will not output an ACDRV signal to both MosFets. Just always check whether the second MosFet is shorted. (and Channel N supposed to have 19V + 6V also 25V on the gate)
An interesting repair as solve to each problem. The customer and the cost as first goal to operation. And the care with heat to hot glue. I am using the techniques to a 50 year old electronic. *Baldwin( (fun machine). (1975). which came to my shop bench mostly working as all original. Also very heavy dust *repair as compressed air. clean out rapid. An circuit board diagram as very early digital signal path.

Thanks for the post and training to craftsmanship....great to learn from your work. Thank you....with "Regards from Washington State, US. McGary".
Almost always the left hinge on HP correct? On this type of job, I skip repair and go straight to "data recovery" mode. I save the files and dispose of the toxic waste for customer. I make some money, customer gets their files and can buy another device. All win. Good trick with the hot glue and loosen the hinge. I give it a try next time. I usually drill through case and send a bolt/washer/nut all the way through case. Ugly yes, but holds. I'm happy you fixed it for them.
I repaired hearing aids for over 20 years and there were many that were old and in bad shape, so you do the best you can for the value of it. I understand this repair job.
Thank you for sharing this kind of video. It is a great lesson. You fix things cheap, that's big. Fixing stuff with new parts and lots of money requires no skill by comparison. No street ingenuity . Nothing. In places and houses where money is tight this level of skill is invaluable.
Îmi pare rău Sorin, ai cam rămas in urmă cu ce se întâmplă în România și in București cel puțin un laptop ca ăla ajunge cel mult piese de schimb dacă nu direct la reciclare, nu mai repară nimeni așa ceva! Ar trebui să vii mai des acasă, lucrurile s-au schimbat mult....
Vorbești prosti...verifica preturile pe OLX si grupurile dedicate pt vânzări. Se cere pentru orice amarat de laptop bani. Vorbesc din experiența, ca si side hustle sa zic asa, vand laptopuri SH.
I may not be working in a shop at the present time but I have done jobs that made me wonder why am I doing this for so I do understand what you are saying and also you have done an excellent job at low cost you feel good that is what counts.
Having a repair shop,I know first hand about getto style repairs,old laptops and customers who don't want to overspend.I always explain that I ll do patches and not component replacements,and if they agree I proceed.
Sorin, great man! Another functional repair! that's what it's count! At end of the day, it's nice to breathe! Dodgy or not, it's funcyional? If yes, they should be fine!
sorin i know you help a man. who don't pay much money on the laptop. probably no one helped the men but you did. please upload all kind of videos becouse we so much learn from the your videos. Thank you 🙏 love from india ❤️
I once had a laptop repaired for a corporate client, it was a crematorium. The laptop was full inside, but really full with very fine dust. I know it wasn't what you think - it can't be, can it?
Dear Sie-Tech yours and Sorins repair videos are my most favorites, its a kind of surprise to me, one master commenting on another one :) . As a hobby repair person i learn so much from your work, i cant thank you enough.
@@cagataykilic7978 Hi, of course I'm here. Sorin is very experienced, it is worth following what he does, even if you are doing the same work. Learning this work is a never ending story :)
You had the two hinge holders inside the screen protector. Put them back on and heat the plastic so it bonds together, reinforce with epoxy around the holders, screw the hingle back in. Like new. No need for the hot glue.
Seems like you'd have super glue remover on hand, test it on a part of the plastic and soak the port in that. Then epoxy the hinge and the port into place with minimal application. Almost the same amount of work/time but doesn't seem that glue will hold the hinge. Maybe customers appreciate the economy version costs but others might want an option to have it done right.
Maybe you already mentioned it somewhere. You can obviously see how much voltage and current is flowing to the device when you use power supply with probes. My question is how do you see the same when you simply connect the laptop or phone to a charger? Am I right in my assumption, that your power supply has a USB output, that also shows you this info when you connect a device to it?
Sorry master,you can trace the signal where it is come from. May be it is a simple open circuit like an open resistor. By the way,you still the best teacher I follow. Greetings for Burundi.
I don't think you need to apologize for such a job, you did everything possible for such a job for that money, it can normally be done better, but it takes parts that cost money and it takes more time, and it costs, in the end a job well done
I bought a new 1920 X 1080 screen for my 12 year old 16" Acer a year ago on ebay. I payed $19.95 for it with free shipping. It still works great. I got a great price only because there are so few like my Aspire 6920 that are configured for full HD and the seller wanted to get rid of about 50 of them.
Some people want you to take chicken poop and turn it into chicken soup and make it taste and smell good too. That's what this job is. Somehow you managed once again to work a miracle on a scrapper and made it at least functional. Saved the customer data recovery, and an immediate purchase of a new laptop too.
Thanks for sharing the reality of working on this Sorin. That kind of job is a "meat & potatoes" work. So many jobs are like this or worse, I completely understand why you wouldn't want to spend a single minute more than needed for it. and Yeah, Gloves! ~v~
I just repaired my own lenovo g580 hinges, the hinges were broken off on the laptop side, the keyboard bezel was forced open when i closed the laptop, i came up with the idea of melting 2 holes through the bottom case of the laptop, using 2 long screws on each hinge, i placed a small metal plate on the bottom of the laptop where the screws go through, inside the laptop, i bolted the screen down on those 2 long screws, and i have to say, its super sturdy now, the hinges don't crack or move anymore, i mean they move in the normal, expected way, and ok, i have now 4 screw heads and 2 small metal plates on the bottom of the laptop sticking out, i painted those black so they would blend in more, but its the underside of the laptop, so i don't care at all. The model i have is known for its weak hinges, and i think that my solution, is the best way to fix those hinges for good. If it happens on the screen side, i know what to do next ;)
most people don't understand, that hinges with integrated stopper (that have a proper amount of conterpressure), like laptop hinges HAVE TO BE MOVED SLOWLY.... seeing so many moving the screens so fast, that hinges cannot live long... but some laptops have also a poor quality....so the chance to break the hinges are double...
you should have 3,3 v on the battery bins on motherboard when the battery out ,if you have not, then you have frequently a problem with charging circuit
A little while ago i was watching one of your clever videos when you said you had created a fault on a Lenovo ideapad 100s feeding it with too high voltage. I have done the same. I looked to see if you produced a repair video but couldn't find one, so did you or should i bin the computer given its age and limited capacity.
Great video....I have a question 🤔 when you did spin the mosfet around..u short the gate pin with 19v which means that u sent a 19v to power ic responsible for switching the mosfet and this could be the reason for not charging? Is that correct?
A very good economic repair. Some would not attempt but if an understanding is reached with the customer then no problems. And this is one job that another repair shop is not going to get now. ALL jobs pay the bills 👍
You the best. I'm one of your leaner followers and have a special folder just your videos in my laptop. May God bless you. Believe it when I say you helping me feed my family. Best of love from Africa, Botswana
as long as you told the customer about the problem and he decide what to do, you are applying in my opinion a clear and honest way of doing business.
Hi, I am from Argentina, we do a lot of this kind of repairs, laptops here are very expensives, so we repair as much as we can. Thanks for the video! helps a lot!

Thank you....with "Regards from Washington State, US. McGary".
Almost always the left hinge on HP correct? On this type of job, I skip repair and go straight to "data recovery" mode. I save the files and dispose of the toxic waste for customer. I make some money, customer gets their files and can buy another device. All win. Good trick with the hot glue and loosen the hinge. I give it a try next time. I usually drill through case and send a bolt/washer/nut all the way through case. Ugly yes, but holds. I'm happy you fixed it for them.
I repaired hearing aids for over 20 years and there were many that were old and in bad shape, so you do the best you can for the value of it. I understand this repair job.
You are good human Sorin.
Thank you for sharing this kind of video. It is a great lesson. You fix things cheap, that's big.
Fixing stuff with new parts and lots of money requires no skill by comparison. No street ingenuity . Nothing.
In places and houses where money is tight this level of skill is invaluable.
Mr Sorin thank you i wish all the goodness in this univers for you and your family. i learned a lot by you. so thank's
Îmi pare rău Sorin, ai cam rămas in urmă cu ce se întâmplă în România și in București cel puțin un laptop ca ăla ajunge cel mult piese de schimb dacă nu direct la reciclare, nu mai repară nimeni așa ceva! Ar trebui să vii mai des acasă, lucrurile s-au schimbat mult....
Vorbești prosti...verifica preturile pe OLX si grupurile dedicate pt vânzări.
Se cere pentru orice amarat de laptop bani.
Vorbesc din experiența, ca si side hustle sa zic asa, vand laptopuri SH.
BRAVO "BOSS" merci pour vos vidéos ;)
Clean & perfect job👍👍
I may not be working in a shop at the present time but I have done jobs that made me wonder why am I doing this for so I do understand what you are saying and also you have done an excellent job at low cost you feel good that is what counts.
Great video, as always pleasure to watch you my friend!
I'm from Algeria and I understand this .Great job!
Having a repair shop,I know first hand about getto style repairs,old laptops and customers who don't want to overspend.I always explain that I ll do patches and not component replacements,and if they agree I proceed.
I do it all the time.. I learn the hot glue trick from you. If the customer come back its you fault Sorin!😂
Great fix until the screen gets cracked :-) but I can still understand the reasoning
Hello from Cluj, Romania ❤
Of course it is perfect...You did a great job again!
Sorin, great man! Another functional repair! that's what it's count! At end of the day, it's nice to breathe! Dodgy or not, it's funcyional? If yes, they should be fine!
Great fix , Sorin
sorin i know you help a man. who don't pay much money on the laptop. probably no one helped the men but you did. please upload all kind of videos becouse we so much learn from the your videos. Thank you 🙏 love from india ❤️
I once had a laptop repaired for a corporate client, it was a crematorium. The laptop was full inside, but really full with very fine dust. I know it wasn't what you think - it can't be, can it?
Dear Sie-Tech yours and Sorins repair videos are my most favorites, its a kind of surprise to me, one master commenting on another one :) . As a hobby repair person i learn so much from your work, i cant thank you enough.
@@cagataykilic7978 Hi, of course I'm here. Sorin is very experienced, it is worth following what he does, even if you are doing the same work. Learning this work is a never ending story :)
These repairs are absolutely brilliant / very honest and upfront and helping out people that don't have much money / love it / great work
You had the two hinge holders inside the screen protector. Put them back on and heat the plastic so it bonds together, reinforce with epoxy around the holders, screw the hingle back in. Like new. No need for the hot glue.
That customer was surely fighting with laptop or something, he was using it as bulletproof vest for sure!
Awesome Video Sorin. True repair shop experience with everyday Jobs we encounter.
Seems like you'd have super glue remover on hand, test it on a part of the plastic and soak the port in that. Then epoxy the hinge and the port into place with minimal application. Almost the same amount of work/time but doesn't seem that glue will hold the hinge. Maybe customers appreciate the economy version costs but others might want an option to have it done right.
You could donate that laptop to archaeology university, they will find some ancient beings there 😄
good one!
Great Video Mr Sorin. I'm watching you from my daily driver 2014 laptop whose hinges are held in a hot glue sandwich. Like new :)
Maybe you already mentioned it somewhere. You can obviously see how much voltage and current is flowing to the device when you use power supply with probes. My question is how do you see the same when you simply connect the laptop or phone to a charger? Am I right in my assumption, that your power supply has a USB output, that also shows you this info when you connect a device to it?
Hello Sorin nice to see you again 😀
I have the proposition to movie: how to remove black glue from BGA chip in phone motherboard.
Hello Master of repairs
You are definitely right, I understand what you are saying, and thank you for sharing your knowledge with us
GOD bless you
Bravo Mr sorin good job its brave🔝🔝
Sorry master,you can trace the signal where it is come from.
May be it is a simple open circuit like an open resistor.
By the way,you still the best teacher I follow.
Greetings for Burundi.
great video sorin we dont just learn electronics repair from you we also learn how to do business thanks for sharing :)
its a fair price for a computer that has been used as a football 👍
Thank You for this movie . Great job again
I don't think you need to apologize for such a job, you did everything possible for such a job for that money, it can normally be done better, but it takes parts that cost money and it takes more time, and it costs, in the end a job well done
i totally understand u sorin, great job
Great job Sorin. A silk purse from a sows ear.
I bought a new 1920 X 1080 screen for my 12 year old 16" Acer a year ago on ebay. I payed $19.95 for it with free shipping. It still works great. I got a great price only because there are so few like my Aspire 6920 that are configured for full HD and the seller wanted to get rid of about 50 of them.
Some people want you to take chicken poop and turn it into chicken soup and make it taste and smell good too. That's what this job is. Somehow you managed once again to work a miracle on a scrapper and made it at least functional. Saved the customer data recovery, and an immediate purchase of a new laptop too.
Thanks for sharing the reality of working on this Sorin. That kind of job is a "meat & potatoes" work.
So many jobs are like this or worse, I completely understand why you wouldn't want to spend a single minute more than needed for it.
and Yeah, Gloves!

Grandma must of gave it to him and it is priceless now.

Hello, do you where is he from?
Hey, you've got a new workbench
@22:09 - 22:15.. That's a very conceited moment!.. Mr "Sexy"... LMFAO! :)
I just repaired my own lenovo g580 hinges, the hinges were broken off on the laptop side, the keyboard bezel was forced open when i closed the laptop, i came up with the idea of melting 2 holes through the bottom case of the laptop, using 2 long screws on each hinge, i placed a small metal plate on the bottom of the laptop where the screws go through, inside the laptop, i bolted the screen down on those 2 long screws, and i have to say, its super sturdy now, the hinges don't crack or move anymore, i mean they move in the normal, expected way, and ok, i have now 4 screw heads and 2 small metal plates on the bottom of the laptop sticking out, i painted those black so they would blend in more, but its the underside of the laptop, so i don't care at all. The model i have is known for its weak hinges, and i think that my solution, is the best way to fix those hinges for good. If it happens on the screen side, i know what to do next ;)
haters will always hate sorin fabulous repair bro well done the guy should be so pleased with that laptop repair :)
most people don't understand, that hinges with integrated stopper (that have a proper amount of conterpressure), like laptop hinges HAVE TO BE MOVED SLOWLY.... seeing so many moving the screens so fast, that hinges cannot live long... but some laptops have also a poor quality....so the chance to break the hinges are double...
Dayum! This guy is really good.
you should have 3,3 v on the battery bins on motherboard when the battery out ,if you have not, then you have frequently a problem with charging circuit
reversing the direction of Mosfet to have 19v in the gate and then opening the Mosfet, No one can do that except Sorin ... WOW
Salut Sorin! 🙂
Sorin, you used to wear a nice watch on your wrist. What's the brand and model of that?

@@electronicsrepairschool Thank you Sorin. You're the master of laptop repair on RUclips.
Good Job Sorin am a big fan
great work ethics, thanks.
A little while ago i was watching one of your clever videos when you said you had created a fault on a Lenovo ideapad 100s feeding it with too high voltage. I have done the same. I looked to see if you produced a repair video but couldn't find one, so did you or should i bin the computer given its age and limited capacity.
You are a master good work thanks for this video
Holy cow that hot air removed that chip so fast, what kind of hot air station is that???
This repair was a mess to begin with, I would have wrote most of that off, tricky repair but brilliant, well done
When you see a screen and wifi card connectors sideways it mean the manufacturer had no idea of what it was doing.
Sorin, im amazed that you could make that laptop usable again on so little money.
The laptop owner needs to treat his computer better.
ya that laptop was utterly abused.
Great video....I have a question 🤔 when you did spin the mosfet around..u short the gate pin with 19v which means that u sent a 19v to power ic responsible for switching the mosfet and this could be the reason for not charging? Is that correct?
A very good economic repair. Some would not attempt but if an understanding is reached with the customer then no problems. And this is one job that another repair shop is not going to get now. ALL jobs pay the bills 👍
