I have seen more than 50 videos, I have never posted any comments...I'm an industrial electric technician, with some love for laptop repairs... Even with schematics is hard sometimes, and this is incredible...doing it like he does, teaching with no secrets like he does...You have win my greatest and honest respect Mr. Sorin... Regards, From Portugal!
You've found the right channel to learn laptop repairs, sir. Sorin is among the top 2 on YT in my opinion. The other one is Laptex. Have a look at their channel. Most of their videos are in Hindi but still there's handful of English videos which I found very helpful. I don't have any affiliation with their channel. Just wanted to help someone who's willing to learn laptop repairs.
@@juliusvalentinas ask a German, Japanese, or Chinese guy they'll explain. In Japan, they rarely use English, not even in design phase. English is not the language of technology, but mathematics is.
it is like watching a movie where sorin takes the role of a detective and starts Interrogating the components until he finds the suspect xD great video sorin and thanks for sharing :)
The only difference, that on Columbo we (the audience) already knew the offender and we were just curious to find out how the detective found a way to prove!
Just gotta say, "Sorin", your video's are "Sic". Trying to learn about fixing stuff and came across you channel about 6 months ago, I've watched everything I can find. Always look for the two mosfets, coil and current resistor now....;-) Please keep doing the long video's, please keep showing the mistakes, please keep explaining. It helps us newbie's enormously... I love the "dodgy" fixes, but once you understand why, they're good. Thanks for taking the time.
i cant believe your skills with the soldering of high pin count ic's .. ive seen others remove the ICs and clean the pads and apply solder to those pads and then try to solder it .. ive never seen you use extra solder .. and as much as ive seen your videos (and i ve seen many .. most ) youve had a perfectly soldered IC every time .. this super IO was an odd one .. and even though twice or thrice .. it moved from its place .. it was soldered perfectly.... my salute to you sir ... ive learnt a lot from your channel .. and to think .. im not even in to the repair business .. i used to assemble and deal in computers long long back 1994 to 1997 (fresh out of college) so thats a long time back .. but thank you i watch almost all your videos
@Sorin, easy way to check SOC (system on chip) (CPU) test data pins of USB ports if one data pin is shorted cpu is dead takes 2min to diagnose, saves time
@@awetaiwo9551 SOC is CPU and PCH rolled into one chip, if the data pins are shorted it means that the SOC is dead as the USB ports are connected strait to the SOC
hi sorin ive been watching your videos lately and for the past years and never gotten to focus up until now, growing up i use to love electronics and repairing things, thou with life hardships growing up and no one to educate and mentor me when i was a lil boi ive never pick up on it, but 32 years now watching you decided to pick it up again and upgrade my self to learn and grow, i bought myself some soldering tools and now learning new things from youtube and your channel, theres a long way to go and thanks alot take care
My bows to You! I'll quote Tina Turner: You're simply The Best! Always a pleasure of watching You at work and thanks for this precious lesson. Hello and see You soon from Poland.
You are like the friend i wish i had, ive learned so much watching your videos and now i only ever fail if parts cant be purchased/mixed or swaped. Also the obvious damage inbetween layers. I use a rework station for small stuff and a old counter stove 200c for reflows works like a dream :D and old style solder irons for stubborn places 🙂
@electronicsrepairschool i've learnt so much from you (lol), after the diagnose i thought it must be a faulty bios, or a partially dead controller (IO)... and when you've said the same around 1:00:00 i was so fckn smiling and being proud :D Thank YOU!
Sorin I hope you find one day the time.. to do it al the way and not in a hurry. I understand you have a shop to run. But I almost see you make two boards in one time but you don’t did it. I like your spirit too always thinking off the shop. Thanks for all the time
If live to the Philippines your the best of the best loptop tech.ever your my idol to repair the loptop.. and i learn to watch your video thank u to share your talent.
hi sorin. on battery the coils will not gen voltage.the chip releases a 100ma low output to the super io .and after the power button is triggered the mail 3v & 5v will get power love from sl
Hi. i am grateful for your videos. you have taught me how to diagnose and repair laptops. please keep up the good work of posting your repairs. always keep safe!
Most of the time the difficult job to fix is missing voltage, you're lucky sorin because you have 2 pc's extra board to get a SIO ,if you don't have a same board or SIO, you can't fix that! BTW is a nice video and great idea, thanks man
hello congratulations I like your method. Allow me a tip. Change the color or pattern of the tips. I can already see it happening.. a voltage test on a 3.3 rail with 19v 5 amps tips :)
bad for business great for us.. Sorry Sorin.. But thanks! I just had a thought at the end.. If the customers could see you working on there lap tops, fixed or no, they would be satisfied you did your best.. I truly appreciate people who do there best.. no matter at what level it is.. Carry on! you truly are good at what you do..
Sorin, I have been enjoying your videos. Thanks for your instructive, practical style 👍. I have one criticism. PLZ mention the make/model of the computer you work upon. If not in the title, then maybe tag it, or mention it in the explanation below video. This way all the people who are looking for guidance on repair of a specific laptop can find it in the Search function.
Hello Sorin! Love you videos. Could i possibly have information of your shop? I would sent a board in for Diagnosis and repair. Lenovo yoga 910 motherboard. Charging issues and the inductor gets really hot. I am a bit lost on the repair. I also have an extra board for parts.
I ask why did the customer made it so difficult by not sending the charger ! Also whoever sent this does know an awful lot about these laptops to have two other motherboards ? Well done you for sorting it out. I lost track of the motherboards early on, would have been useful if they were marked then A,B & C or something. Thank you Sorin.
How could I send my PC??? My HP G4 Pavilion 2205la once decided to only send power to the cooling base, until it drained the battery, after that i changed the power button chip, it still doesn't react at all ( i noticed the LEDs chip is broken) i prompt the 2 power pins and it doesn't turn on.... I'm trying to see if I could get this fixed all thoe i don't even know how to send it to Master
2 dead boards for the same model seems like this laptop is bad, i like watching your diagnostic process you're good at it and for one hour video it's all benefits
I always get laptops with shorted cpu or gpu, never had with shorted capacitor. As i said shorted cpu, gpu or first mosfet. If is gpu shorted u can bypass.
Can this cause GPU and CPU to heat also when plugged in on adapter? As soon as i plug in 3seconds and GPU is 40°C (no heatsink). How is CPU and GPU power controlled? Something is pushing amps..
Hello sir please I need your help my acer r14 is not charging and the technicians I have given says they need schematics to enabled them fix the charging circuit please can you help with the best the laptop works if the battery is charged but will not charge even with a charger
It was Beautiful work...if it was me do that work i think laptop was broket in 100 small pices and put to rubbis.haha but you fix it...thats nice ..have good day..
Can anyone point me the direction of fixing my laptop ? I have replaced the Thermal Paste on it and accidentally blew my Screen Backlight Fuse off. After finding the blown fuse and removed it + short the circuit to see if the issue is still there... the screen is working fine... but now the Battery does not charge anymore. The laptop seems to be working fine only when plugged in ... but dies immediatelly when I disconnect the charger... which means that the battery is not charging. I have removed the battery and tried it out in my new laptop (they both have the same battery model) ... I have charged the battery ... but when I try now to connect the charger... the charger's protection kicks off and cutts the charging power. I have tested the battery from my new laptop as well... and the charger cutts of the power as soon as I plug it in. Any advice on where should I start ? Thanks in advance
"i spent over 1 hour" hahahaha i spend days traying to fix things that are way over my head. Nice job. Im still learning, so far i can fix small easy things, but i dont give up. Im taking an online electronic course. Hope some day be able to fix complicated things.
When Master Sorin says : " Can´t believe I spent an hour " , means I would be happy to find it in a week.
😂😂😂😂
100/100
Sorin is the best man
@opal177 its a boss fight
Same here... :D This man can find an issue in no time, what is really impressive. O.O

watching him replacing these ICs without any problem look strange even for us who often work same kind of things. Pure science fiction :)

Sorin you are the best ( first time i see this double-pins SIO )
Sorin why you testing board on baterry ?
I always connect mainboard to service power supply i watch current .
it depend on set up, he use test prove to inject voltage,.
Great video keep the. Coming, I find it very informative,
nice work
U R my best lectures 10Q sir
What is that liquid paste that you apply to ICs before de-soldering them with hot air gun ? Please tell us.
Your the best.Great job!
great job idol
HATS OF U SORIN
i think you the best one i know it in my life >> thank you sir thank you very much
No qwik fix, but you figured it out and that was an impressive, time consuming hunt. No wonder you don't work on TV's anymore!

How can you discard a case of broken solder, dry solder or cracked solder?
Very nice

Why you do not use a boardview? You spent so many time to find 3.3 and 5 v power rail.
I was confused: which is the powersupply and which was the multimeter (same colours) and which board was which pfff
Sir do regular videos 🔥
Would of bin nice the customer sent you the power supply as well!
Have you tried the vc04 short killer or is power supply just as good?
Can anyone point me the direction of fixing my laptop ?
