"you have to be better than me". that's a Master piece.
Oh welcome back Sorin.
I’m happy to see you again!!
Sorin, you just saved me a laptop ! Exactly this problem, fixed it like you showed it and voila :) Thanks for this lesson !
Sorin!!! finally .. i'm going mad without your videos... checking every day your channel!!!
I have hp 15-ay016nv and charging but I have black screen. I try to reprogramming bios but nothing. Can you help me?
The UK has so many holidays. 😋 In the US it's all about work, work and work. Employers don't care about their workers they just want you to work all the time. Great video.
Same
I have to tell you Sorin. Not only you're the best but you are so nice men. Don't ever change. Thank's for the wonderfull informations i learn from you and please keep making videos. Take care.
Hi Sorin! Im watching you from greece and the only reason i do this its not cause i dont know how to repair electronics but your way of doing it, teach me how to save some time for myself and for my life! thank you for sharing your knowledge!
Thank you Sorin, you are a fantastic teacher and I really appreciate everything you do for people like me. Greetings from Sheffield in the UK. 😊
Welcome back, Sorin!
Those two first mosfets are for reverse polarity protection?
Thank you for everything, you rock!
Get better!!!
You're the zen of electronics. I am just watching it for the flow and the ease.
Best pc doctor. Diagnosis-check. Solution-Check. Thank you! Keep up the good work.
Another brilliant ' Workaround' !
Thanks to you i dare to fix my laptop with just a multimeter and a solder iron! You're awesome 👍😀👊 Cheers Bart
OMG Thankssss. Same laptop, same problem and same fix. Working perfect! Thankssss so much!
Just replaced a Winbond super I/O chip from an acer laptop (because it was the only chip on the board that was slightly heating up), with an also Winbond from an other (totally different) board, but with the same first 5-6 letters-numbers in the chip ID. and it worked....!!!
Also i fixed a similar HP with your way here, but i also tried to replace the mosfet with no luck. Seems like the mosfet is ok but it does not open. So the problem is deeper
Greetings!
thank you Sorin for nice informative video
Buna ziua Sorin ,tu esti Roman am vazut in trunu-l din tutoriale si auzit vorbind perfect romaneste.
Felicitari est un f.bun profesor si util tuturor celor pasionati de electronica.Eu la indicatiile tale am reusit ss-mi repar laptopul.
Thank you Sorin really helpfull respect from Leeds.
Thank you Sorin for the videos. Get well soon .hope all is good :- )
This dudes a genius!
Greate teacher. I originally only fixed phones. Now with ur lectures I fix laptops too. May Allah reward u more. Just haven't tried fixing CPUs coz its a little bulk and not familiar
thank so much mr sorin for the knowledge you are sharing to the world, my self am really getting profited with your what i call class....thank you so much
welcome back Sorin ,nice to have you back here my mentor
SOLVED! My board LA-D702p rev3.0 (applies to other HP, Asus, etc. boards). For anybody having exactly the same issue, where your power mosfets are not turned on and you get something around 0.9V on the gates. 1st check if the MB works as Sorin's method (czcams.com/video/-IrPWbA3i-o/video.html). Than check the second MosFET, in my case it was "7506 AON7506. 30V N-Channel AlphaMOS" shorted and gives false feedback to the power FET driver namely BQ25A (TI bq24725A) so it won't turn on both of the main power mosFETs. Replaced it with another compatible N-chan fet 30V 12A and all works. Accepting RedBULL + Cola or else :D
Welcome back Sorin! Thank you for another great video! Get well and hope to see you soon!
thanks, very useful, before disassemble the laptop first I check my charging port, not problem there, but when I check the charger, the middle pin is bending, so I make it straight again with needle carefully and it work...
welcome back Sorin. hope you are doing ok
I salute you bro...Im from South Africa, i learn from you man, you inspire me
Glad to see you again really...
good job! you're the teacher i never had!
I was watching this video again, I always learn something else.
Hallo master, nice to see you doing new video again...
I always admire your job. Well done!.
welcome back sir , i wish you in USA working for me , we can get so many repairs day to day . come to Maryland
Hi sorin there is a way if you have bios in super IO without replac it just use Vertyanov
13:27
Using flux, flux is healthy... 🙄
For solder i mean..😂😂😂
The key words here , do what works for you in your situation. Obviously Sorin your way of doing things is working for you and your boss and importantly your customers. If it wasn't you would be out of a job. Customers complaining about a job not done right or the price is to high would eventually kill the business. Not everybody has deep pockets full of money. So you offer a affordable way to have something repaired. I believe your 7 years working there. The group of you guys must be doing something right. And you share your experience and knowledge and some not all who have shit there common sense out when they were babies will take the information provided and miss use it or bash it. Hope your feeling better. And thank you for taking the time to make and share you videos.
Useful video 👍
You make it look easy.. Dayumm
Thanks for the educational content you are a great teacher. I have a HP x360 M3, now my question is what if I’m not getting power to my mother board, my charger is fine and so is my port, what can I do? Thanks.
The Sorin Method is A-Ok for me.
Ohh that voice, take care of your health, hope you get better soon. Thank you for the video
The first mosfet gate is often connected to a circuit to detect input voltage, if there is not enough voltage then it does not switch on the mosfet.
I now have to call you "The bypass man." :-D joking sorin :-D.
Worth to check it with battery plugged in.
good job sorin..😃
nice video 👍
missed you friend
WOW AMAZING DUDE KEEP IT UP HONESTLY
I have a hp 15 ra005nia that when plugged in light at the adapter area goes on but when switched on, the power light switches on temporarily and then off.
Get well soon.
Master 🙏🧠
Hey Sorin, Hello from Florida. Good to see you back !
Really Nice
You’re the man!
hellooo welcocme back i was waiting for u thanks a lot
Buna Sorine, baga si un repair school
pt. fratii tai romani :)
tengo el mismo problema en una placa similar a esa una crl51 el drane del primer mosfet con 19v pero en el source me da 0v por lo que los demas mosfets tambien 0v asi que verifique el gate y esta bien, pero la resistencia de sensado me da continuidad en tierra ¿por que ? si no tiene que conectar a tierra. La continuidad a tierra paso hasta el drane del tercer mosfet pero no hasta el source asi que creo que el problema esta entre el segundo mosfet o en uno de los 3 capacitores que conectan con la resistencia de sensado, pero no se cual de todos son.
Information taken , thanks !
Thanks sorin from tz
Africa rules! 😁
Great job thanks for the video !
I love mosfet job
Thank you very much for your video. It was useful for me. Could you please tell me where I can find the used monitor for it? Thank you!
another quick tutorial and review....more video sir
thanks sir from Ethiopia
But in new laptops model like this when I make a bridge over the mosfet, everythings will work fine but the laptop will not charge the battery, so how can we fix the charging issue?
And even if I replace the mosfet, it still no power.
Love your videos, excellent work sir. One question please: what type is your headset? It is very clear and looks comfortable, so I was thinking of trying the same. Thanks.
Hi .. you are excellent teacher for me
I have the same motherboard but in the first mosfet to out, I have -19V , in the R010 too .. I think negative is comeback
Why ?? Can u help me ?
Hello
After this repair, the battery will not be charged.
The input transistor is not actuated.
True. That happen to me too when i bridge. Can only Turn on with battery unplugged .How do you fix properly?
@@deegthllop5316 you have to find thee reeason why the mosfet is not turning on in thee first place
i have hp pavilion 15 -cc055tx, it's led near dc jack not glowing, caps lock led also not blinking, but led on power button blink 2 times and off and again two times blinking, i reprogram the bios with programer but it not turning on
brilliant as usual Sorin, well explained and it saves another laptop from scrap. thank you :-)
How long you take to come over again....
well thank you for your videos
Will it charge the battery though? I fixed a hp like this once but it stopped charging the battery. Any ideas plz? Thanks
awesome thanks so much
Thank you!
the messi of electronics
Hi hopefully you are able to answer this because this video is from a while ago I have the exact same laptop only difference is I get power power light it turns on and everything at first it would stay on for some time with charger plugged in then completely turn off, but work completely fine on battery power, now pretty much as soon as you plug in charger it turns off.... To charge it I turn the laptop off and let it charge then turn on on battery power which works fine until dead .... Do think it's same problem as yours ?....
Additionally I have tested a new charger it did the same thing just not as quick so I'm sure the fault lies within, I also notice that the battery logo is moving up and down as it does when it displays charging shortly before it cuts out it stops moving but maintains a plugged in sign then completely cuts off, you did mention mofsets in the charger and board I'm wondering if it's sensing a short or failing resister ect and cutting power
The mosfets replaced are the two at the start or different ones. Forgive my ignorance but I also have a bad flu and am finding it difficult to concentrate. What blew up at the start
Sorry to bother you i have the same board that is dead same as here and i dont have external power source so i can inject power beyond this mosfet is there any other way to check if this mosfet is shorted. And if i Short this can i make more damage if it doesnt work?
i have the same motherboard .when put charger light white when put battery it light red .voltage are ok.light on charge ok but no powering.no shortcut no heat.maybe bios fail ?.any idea plz
Thank you
hi there , how we can find and identify 19v power rail ? please more explain
How do you know if a super io chip has bios in it or not?
Very interesting video thanks for keep doing works and uploading to CZcams. Thanks mr!!
Thx :) get well soon :)
nice video, what if it's charging but cannot turn on?
Hi Sorin I have the same laptop but with a little different problem. The problem is that with the battery and the charger plug it in is not power on and blinking orange the indicator led. With the battery unplugged and only the charger is white indicator steady and no power on only the fan can see a little movement but nothing else. I have already measured 19 volts on 2nd mosfet and in current resistor in Vin. Can you please tell me what is possible to going wrong?
Good job Sorin! Flux is healthy. XD
Sir HP 15 r auto charging ....keise thik hoga.....
Thanks a Ton!
EXACTLY same laptop. different problem. PCIe/rj45 controller overheating (rtl8166EH cg) and not boot. but power and charge lights are fine. please help.
Hello teacher, I've been following your work, they're very good, but I have a PC that has all the tensions, but press opwr, I don't care, what's your suggestion?
The computer brand is hp 250 alpaca CTL51/53 LA-E841P
In this laptop can we use fan or heat sink ? It is possible or not
"okay that's not good" (vaping deeply). And all is done
I WRITE FROM ANGOLA'S PRIVATE AFRICA
here is a great channel , anyone have any clue about a hp with core i5 u series, that only have 3 volts on bios when pressing power button, and processor heats as hell when pressing same button?
dats owsome...thums up...
I have a hp notebook 15-r206tu but my motherboard is dead , with kind of motherboard is good for it ?
