You make it look really easy to fix and work on electronics. My dad was an electronics engineer and taught me quite a lot, but I never got to the level he was. You teach in the same way he did. Thank you.
You Sorin is the Bob Ross in fixing electronics! Every strokes with your red and black probes over the components makes us shiver in pleasure when you find the problem. 👌
Watching you repair these laptops has been a real education for me. Thank you.
I have a new Acer Nitro 5 (AN515-57) that is not charging also. I was about to spend a bunch of time looking in the wrong area (at the BQ chip), but this video was beautifully timed. I checked my input MOSFETs and at least the first FET is shot, the 2nd is suspect (I'll have to wait until tomorrow to pull out the first one to confirm whether its just that). Thank you Sorin.
So it worked?
What a great tutorial... I really like what you are doing for us❤
Nothing like a beautiful day and a beautiful laptop! I, too, woke to a beautiful day and a niiiice laptop repair. Thank you, Sorin! xo
Thank You Mr. Sorin. God bless You.
Where I'm living in Nova Scotia Canada it reached 34 degrees yesterday(Friday) not counting what it felt like and we have been under a heat warning for the last few days. AC was my best friend lol
Same here in Pei
Sorin. România a pierdut oun om de valoare (ma refer la tine) , așa cum a pierdut o sumedenie de medici, tot oameni de valoare. Toți meseriașii au plecat din țară. O zi plăcută și un weekend liniștit. Multe salutari din România.
Daca Romania nu stie sa isi tina oamenii nu o sa stea nimeni doar ca e patriot.
Finally friday yeah! and Sorin has never run out of the learning lesson. impressive!"
Thank you for another awesome video, Master 🙌🏾
Thank you, Sorin, great job as usual!
Sorin check the fan on the left side. it looks like it's clean because the cable on top is blocking it. The one on the right is dirty like you would expect.
Looks like the customer damaged the tape on LVDS cable, and is now rubbing on the fan, you might want to sort that. Congrats on the fix.
Hi Sorin. How did you know that the replacement mosfet will work? What should I chceck/pay attention to when choosing a replacement?
I think that mosfet is easy to find on other laptop. But the other one has number code need same code
Thank you Master. You have very How now,
Great!! Regards from Romania..I watch all your videos...what power station and multimeter do u use now? God bless you! Sănătate
Mosfets ❤ when it is an easy fix. I have regular encounters with mosfets replacement😅
Another "it's workin" motto , good 💪
Thank you ,you're the best
Helios 300 uses a 300W charger. That's more than old days regular desktop power supplies hehehe. The newer Helios has a longer battery taking away the 2.5 slot. The older model with 3 slots is nice being able to have the 2.5" for backup and the two nvme's running regular processing.
As I can recall there were 2 laptops back to back with same mosfet issue couple of months back.
Hi I’m watching some of your videos and I positive you’re the kind of knowledgeable person I looking for years.
There is any possible way to know where are you based ?
I have a rare vintage pioneer A-70 amplifier from early 80s.
I would love to have that beauty working again
He's based in UK - www.youtube.com/@electronicsrepairschool/about
you have a nice electronic precision screwdriver with type-C charging port, can you share what is the brand name, the model no. and where can we buy it?
Best 👌 job friend
ime, seen a laptop with only smd capacitor (big, 'black') and smd component looking like a wide resistor or fuse but with 'p' in its marking, at input, and see no two mosfets, cept further in next to coils..
you are an expert !
Hi sir i love u r Knowledge ❤❤
Why did you not test the second mosfet before taking it from the board that to could also have been bad? Then you would have wasted time unsoldering and soldering to the board
Good job mate 👍
Sorin video or views on ic drilling or scalping
Hi Sorin, I got a Question. Why is the voltage above 24 volts on the first mosfet after replacing it? Wasnt it ment to be equal or lower to the power supply voltage?
Yes it should be lower or equal. A little bit higher won't matter though. But this is why you should not just replace a component because it looks the same or does the same job as there are thousands of different specs.
@@cfq.tufanuf7601 Thanks for guidance!
He was checking the gate of the MOSFET. N-Channel MOSFET's require a higher voltage in order to switch on, so the gate is driven in this case 5V higher than the power supply.
@@christianaylward7997 understood. Thanks!
@@christianaylward7997 so inside that chip which drives first two mosfets must have boost converter inside to supply 24v for their gate..
hi , i love your videos, you already fixed two laptops for me in one night. i have this exact same laptop and issue. i changed both mosfets in my case
when i check voltage on charger i get 19.5v
when i check the DC jack with charger it drops to around 0.04v
then i check the charger again and its still 0.04v
only if i unplug the charger and replug it and check the charger again it’s back to 19.5v
is there something shorting out the charger ?
i have also replaced DC jack
i have no customer history on this one . any help appreciated
thanks 😊
Sorine acum 2, 3 ani înlocuiai primul mosfet cu sârmă și ziceai că încarcă bateria f bine , aici cum de nu încărca? Cum explici asta ?
your accent is very cool
awesome
Interesant, deci si eu am cumparat o baterie noua, apoi un incarcator si tot nu incarca bateria, desi icoana de jos arata ca este la incarcat, bateria sta la 0%. Model Acer Predator Helios 300 ph315-51. Deci posibil sa imi trebuiasca aceiasi operatie facuta dar nu ma pricep si nu stiu pe nimeni sa faca asta, in zona din Germania unde stau acum. Imi poti recomanda de unde pot lua exact acest mosfet si aproximativ ce scule sunt necesare pentru asa ceva ?
Thanks 🙏
On Helios 300 first mosfet is 100A. Often this one EMP21N03HC
Plz sir, I had this problem today and fixed it by changing the old MOSFET and there was a burnet small capacitor underneath the graphic card,,, how to prevent this from happening again. Plz answer me. Thanks
I now have the same problem on my replacement laptop (after 4 years) but only with videos with a higher resolution, the CPU goes up to 80% and then it just shut down. ☹☺
THANK YOU I HAVE THE SAME MODELMAYBE A WII HAVE THE SAME PROBLEM
Great educational and interesting video (as usual) - may I ask what power supply are you using as I cant see one in your Amazon shopping list or if it's not available any more what one do you recommend please?
Power supply could have a blown MOSFET in it which is causing MOSFETs and s*** to blow inside the laptop which is actually very very very common to see in the US but probably not in the UK Good chunk of the time it's actually the power supply here that caused most of the problem
Great!
I had a laptop that was shuting down when heavy gaming. After a lot of testing i found out that it was the charger. Just to know thats a possibility too.
Did screen use to distort and freeze before shutting down?
@@dhankthapamagar3389 No, it was instand power loss.
@@djradimix Thank you for the information.
mine does@@dhankthapamagar3389
Can you repair broken vga cable pins
sorin, do you have a theory on why these mosfets short so frequently? combo of excess current from high current aps on laptop & air temperature? purely a guess. and how much due to design vs how much due to user?
I wonder if this is what happened to my Acer Helios 300 laptop, bought one off eBay, (After i bought it the seller disappeared) Ran a game, soon as the laptop started to draw power for the game the laptop shut off and it's never worked since. i'll have to check those Mofset's, any other ideas? I'm hoping to try and repair this laptop board.
hi, do u still do coffee and electronics saturday live stream ???🤔🙃

Hi Sorin needs your valuable help. After replacing the Acer Predator Helios 300 Laptop LCD Panel, the Charging Light does not come on at all. There is no power to the laptop. At first the blue light came on and then unfortunately it went off. Many people on the Acer Forums experienced this problem after replacing the screen. Most of those who experienced this problem changed the LCD screen without removing the battery. Could this situation have caused a short circuit on the motherboard?
U gotta love how mutch he wants the vid to have 10
Why 25v at gate?
Nice Laptop
where do i get all your courses bro ?
Great analyses and fix. Now we know, nice laptops (not beautiful ones) are actually second-rate, ho, ho.
So this model has common fault with 1st mosfet?
sorin how do you recognize a dual mosfet aside to others? and how to replace mosfet if you dont have that model mosfet?
I wonder how you connect the charger to see the current on another screen?🤔
check previous post
Grandpa... What gaming laptop do you recommend? Since Asus & Acer Laptops always experienced Capacitor & Mosfets problems. 😅😅😅😅
The best gaming laptop is a desktop, because of cooling 😂
@@irasthewarrior yeah but even an ITX build weigh so much around 15kg and not so portable if you always transfer to another place. 😅😅😅
@@earlbond2929 The man said that the best gaming laptop is the one with the best cooling, not with the fastest cpu/gpu, because it'll quickly get thermal throttling and lose performance. He's even done a video on this specific topic.
Sorin your smarter than ChatGPT, I asked ChatGPT what's the best way to find a fault on an electronic circuit board, it gave me 8 steps to find a fault, meanwhile you can do it in 3 steps or less, your a wizard.
Sorin, what do you mean when you say "sold mosfet"?
Heavy duty. Can handle more amps than your average laptop uses.
Hey can you please help me with my acer predator helios 3000 p315-53 .it suddenly turned off while it was on charge and i was using it...but then it never turned on and also not charging.
Having the same issue with the same exact model
Bro did you find any solution for that, if you did please help me!!
randy any solution yet?@@randy0210
My predator is generator 11.8 amps..
👍👍👌👌
That Laptop Chrip sounds
I think the one of the cooling fans touched the desktop mat😅👍 Sorin didn't really care😂
During my technical education, my electronics teacher never allowed me to say that something was 'perfect' or even 'excellent'.
"You do mental masturbation", he would say... 🙂
Caldură mare mon cher
what is your name good sir?
that is funny just fix that laptop yesterday
my helios 3000 die 40 min ago😭😭😭😭r.i.p
😄👏👏👏❤
Hello🤝👍👍👍👍👍👏👏👏👏👏👏👋👋👋👋👋👋
Heavy gaming with a classic HDD instead of SSD?
Owner is sadistic?
I heard a sound! Means that HDD could die soon. I will put that HDD in the garbage and install a SOLID SD, then that laptop is going to be faster than before.

Hello fluke master
Hi Sorin, Why didn't you check the ratings of the replacement part? You take a random part and assume it is equivalent?
a mosfet it's a switch, electronic switch and there all i need is around 10-12Amps switching, but, most of these mosfets are capable of 80Amps+ so... nothing critical in choosing a random mosfet for 10-12Amps switching

expensive laptop not even a year mine is and already has this problem that means low quality chinese junk next time im buying dell or hp
In your country the temperature makes no sense 32 is just about freezing here in the US below zero is below zero and your country I don't know what you call him minus 32 cuz that's what you guys consider zero here we go 0 - 1 - 2 - 3 on each one see what I'm saying oh no it makes no sense there bye 32° is 80 something in your country that why that makes no sense why I just say 82 I don't get it
Because the rest of the world uses Celcius except the USA and some smaller countries. Oc is freezing point of water 100C is the boiling point of water at sea level.
@@GregM I still don't make no sense cuz 32° here freezes water
@@andyvitz In celcius 0c has a significance because water freezes. What significance does 0F have? Absolutely nothing.
@@GregM 0° Fahrenheit is where saltwater freezes
@@GregM now does ours make more sense
