You have an incredibly challenging work environment, Sorin! The mic you normally use blocks out the background noise for us. But this time, we could hear what you face daily. You have to deal with so much noise and distraction every day. And you have so little space to work on the things. All this, and you're still able to work so efficiently and teach us along the way. Wow! You are a really talented and patient teacher. I'm sure the mic will be sorted in future vids. Thanks again for all your efforts!
Natural selection of tools - You've made my day, first I was laughting, then i realize that on my desk is exactly the same situation when I repairing electronics, tools used very very rare lands on the floor when the desk ends ;)
I like playing Your videos when im repairing things, even if cant watch, just to hear what You have to say
Started from the oldest and watching every day for few hours
Few tips from Your videos was very useful, keep it up, good work!
I really like the ambient noise, it's simply nice, itțs the vibration of that place.
A huge thanks for all your work and effort. Really glad you take the time to teach how to solve problems like this.
Keep up the great work. Wish you the best :)
Great Job. Your videos helped me a lot to fix my motherboard. Even though I had the schematic was still finding it difficult to figure it out. Great help. Thank you.
i am really addicted to your videos, i got too many things from your video thanks.. thats unique specially the way you
describe the chips,faults,and other problems....
I miss your videos, nice one. Thanks a lot.
your channel has finally become my Laptop reapair bible as well as my mobile phone repair bible.....your videos have been really insightful and also you have successfully helped my courage. the whole New year Holiday has really helped me to increase my knowledge in my chosen profession. thanks a lot sir Sorin)
Great job
I became addicted to your video and check the bell video cause you are the best

I enjoy the fact that you are not editing out the road blocks and rabbit holes. Keep up the great work!

Great video! That was painful. Just do it your way, the way you like to do it. I like how you do it, quick, efficient, precise, smart, and the most important thing, it works!
When you explain which mosfets to short and which ones not to short, that is enough. Do it your way, that is the best way. and Thanks!
thank you, i will

Great. This was so very helpful to identify my issue and explain/guide how to fix. Worked for me...thanks. Really like your honest, open and chilled style too :-)

Hi SORIN!!! Thanks for your time, your effort and above all your explantion, for now it's 100% accurate -at least with my level- but for your way of repairing I don't mind since you can fix the issue so don't waste time trying to do (default repairing) this is obvious, keep shining and as I already said you are inspiring and I became addicted to your channel too, have a nice day!!!!
u r right, thx
Great job. hello from Greece!!
thank you sir and get well soon.....😷
Thx
you are excellent teacher i learn from every video thank you
iam from indonesia, and i always watching you, to learning 19v power must on, etc, thanks, success for youu....
You are my good Theacher
Hey we all have those days of forgetting stuff, you are not the only one :-).
You still have a bit of a cold, you are not 100% yet.
You may want to discribe the power channeling mosfets as "Gates", open or closed gates, for people that dont understand.
Usually if the mosfet has a P junction, then the gate voltage is lower than the drain to switch on, and a N junction gate is higher than the drain, as far as i can remember, but mosfets are something i didnt learn much about lol.
i could be wrong LOL
no, your right
Actually It's the difference beween the gate and source (Vgs) which turns on a MOSFET. N channel, the voltage is positive beween the gate and source, P channel it is negative. This doesn't mean you need a negative voltage on the gate, only negative in relation to the source. In that circuit, the source is connected to 19V, the drain is the output to the rest of the laptop, and the gate would get pulled low to turn it on. I found a quick tutorial here which might make sense of it. www.baldengineer.com/p-channel-mosfet-tutorial-with-only-positive-voltages.html
I really appreciate this alot thank for the videos
YEAH!! another successful repair
It is easy to understand any subject like electronic or auto diagnosis, but trying to explain to others in words is tougher than most people thin when you are doing it on the fly without rehearsing before filming.
many thanks,sir.
Nice job and thank you very much because you don't replay on any comment for me on your videos.
nice lessons for me thenkyou great video
hi Sorin , had an LG G3 totally dead , last resort warmed entire phone up (on a hot radiator) hey presto back to life!!!! would never have tried this until i saw you do it with a samsung CHEERS!!!! (btw i only use the LG for a screen for my quadcopter..lol) also has a no read sim card issue, but thats another story...keep up the good work
We love you!
i love you all :)
Best guy on RUclips topman
very helpful THANKS
nice job sir
Such a great video! Thanks.. I am a newbie and I would like you to suggest me which of your videos can be a good starting point towards laptop fixing. Thanks very much and keep up the good work!
good job my good brother thanx
Hello sir. Thank you
Amazing job you're doing here, I constantly watch you videos, and I'm so generous for your knowledge, please open a patreon and I will donate to you, because you make a difference in repair industry.
EDIT:
Please make a video on finding short on motherboard in deaph.
I got accepted in electronics engineering and i went for it only in hopes of this person, GreatScott!, ElectrooBOOM and few more pages since they teach me lot of things and with help of 2 more people, now i repair TV's and i want to grow to be able to repair everything. Thank you electronics repair school.
thenks for your video
what !! That is a video that i have tried to get for years. I have no word to say,just keep silent and listen to your video
very good, thank you ...
Thank you sir.try is best
you'll always be the best💯
Sorin, cei doi mosfeti sunt de regula de tip P chanel. unul e ous invers fata de celalalt. Daca chiar ai nevoie, cauta schematics pt hp 4510s si poti observa. Sunt si modele cu unul P si unul N, chiar si modele cu un singur mosfet P ch. Sau uita-te ce scrie pe spatele mosfetilor si vezi ca sunt la fel. Cauta apoi schematics pt ei pe net.
I think Sorine could fix a Laptop with Stone age tools...
Dude ur pro...hope to learn more from you >3
hope you can learn only the good things :)
Some charging ports can become damaged through constant wear. I have found on some DC/IN connectors that the central pin & the side rails can sometimes become loose or bent enough to not sustain a proper connection with the adapter end.
Where is my shorted Mosfet 😁 I can't believe you replaced a Mosfet
good job
Oh jeez, I just did an overhaul on one of these, I think just slightly newer. Slick, when they have modern SSD and RAM.
thanks a lot
Great job. I think we will be happy if you make any videos of anything what you fixing without learning us. Who following your videos they understand what you doing. For example I would like to see hou you working every day :)
soo boring ...you dont want to see that
Electronics repair school why not mate. All the time I'm happy watching your videos.
48:47 never seen someone so happy after replacing a mosfet xD
Tip: When searching on google for images select 'tools' (under the search bar), then select size.
Ur really great sir
loves yours vedio. great great.
From 52:40 on remainds me on thinking about "Monty Hall Problem" /game show with three doors , goat or brand new car ;-)
again Nice video plz upload some no display issue videos
please check , i have a lot
Thamks
.. : ) thanks for a great lesson..
nice video like all the time just dont be sorry ..........
Thanks a lot, after removing the mosfet would it work if you only jump it with a wire like you did in many of your videos? if not way?, thanks
You're the master
great thanks
I have a Toshiba Satellite laptop. My first mosfet reads 5V at the Gate. Should it be reading 19v? It is a P Channel Mosfet
I've been fixing laptops on the side for years And these videos are getting me to go back and look at the ones where the dell blue light turns off when plugged in!! So exciting haha
that should be easy :) let me know
I like your dogdy way of learning elektroniks. Its wery useful for me, its like i hawe some nolage, but i'm not so god in matematiks. So i need the croul way of learning how it works. Beutiful way you learning away elektroninks on. Thanks from Norway
Nice one boss
I had to do that in 2010 when my multimeter died and had no way of repairing things lucky i was that i just got an Oscope
You can test the 2 first mosfets located above the ram slots just by removing the hdd, ram cover :) you just didn't notice them
Background sound is noisy....
But the Tutorial is most important thing
Thanks
thank you
Great video Sorin. When we put the charger cable on toshiba laptop and cable is not stable in the jack, do we need to replace the charging port or can be fixed some way?
well, depends of what kind of damage is there, if its cracked inside, you can fix it with hot glue
hi, I insert the power cord tested the adapter which is getting power also the pins in the power connector waited for minute but nothings getting hot. what else to i need to do thank you.
I think you forget to play on your mic cause there is a lot of noise in the background of this video
Will you please check out sound in the next video
Thanks
i love no cut videos
pls i will like to know what could cause a laptop fan to start and stop which den later leads to overheating and shortdown of the laptop. my sony vaio does and my fujitsu also
Hi, I need your help. I've got an OKI MC 562 all in one laser printer and the motherboard is gone. Any suggestion on how to repair it? Thanks in advance.
te rog eu sa folosesti in continuare power suplay chestia asta ma atras sa ma uit la videoclipurile tale si in plus daca mai arati in continuare cei care au gresit o sa inteleaga ce au gresit
I think my problem is similar but where I buy the MOSFETs and the other two elements that you replaced or the part number of the MOSFETs
You are the best one this i didint finde bether video for laptop reparing yet.i hawe some thing what i didint figure yet meybe you now somting abot this,i change the cels on laptop batery and now it shows plung in charging but its not charging i lef it ole day long on charger and nothing.Taptop battery pcb shots down i dont no how to reset is.Thank you for answer and big Hello from Hungary
What are the most common types of mosfets, fuses, and capacitors, for most laptops, and where can i buy them, thanks.
Scoring you are super
Great job once again.What would you do though if still the laptop turns on all voltages are ok and still no display?i was given a same model a year ago and i still have not figured it out.Can you please make a video about how you can check ram sticks , cpu and gpu?Greetings from greece . Ps .i have a new moto now, IF YOU CAN SHORT THEN SHORT,IF NOT REPLACE !
Hi, is no way to check the ram if the screen is black, just replace and check again. I do have few video about coming on but no picture on the screen
