I get that same satisfaction when I complete the repairs, I admire those who have that same joy and don't act like it's just another repair. I became a fan of hers and here in Brazil, I say "the job is done" my wife looks at me strangely, what is it, speaking English now😂
I think I'm addicted your videos. It is very satisfying to watch searching for the fault and fixing it. You are one of the best technition no doubt about it ...
I knew nothing before i started watching you about micro soldering etc. but i started watching you because you have very calming voice and its nice to work and listen to you explaining stuff. Now i know something but i also know that you have nice personality and you are great guy so i wanted to say thanks for your video and educating how to do things. Now i know that some things what i thought are not fixable could be fixed. Also your talks how to behave to people or to customers are very usefull for everyone.
Alex in regular school I was not able to keep track of a single subject. If the teacher will say every time mosfet mosfet mosfet. From most of the times you upload videos about Asus and mosfets I have learned alot about mosfets and what is inside the mosfets. I broke them for fun. You dug into this subject and that's how I learned. First time I did not run away from class, like I did in 2000+.😂
When you repair the motherboard it looks so simple, yet you had at least one thousand devices in your hand so that you can see "the factory flux that came underneath a mosfet" and to actually be sure that's the component that cause problem. Phenomenal usage of tell tell signs.
By the same logic you should never buy any brand of anything. All brands have problematic models, plus you never know WHY exactly has a device failed. If you have to, at least judge models, not brands. 😉
They sell millions of computers. It stands to reason that repair companies will see more of them. It's the failure RATE that's important, and without knowing failures vs sales, that's impossible to know. How much and how they're used is also factor. Asus are a commodity brand. Buyers of high-end models are more likely to know how to treat them well.
@@GaryB007 I might be wrong because the laptop i am using right now has been bought in 2011 and still runs perfectly. It is not asus. I will go with the same brand i currently have for sure.
Amazing video! Im such a fan!! i have a motherboard for my desktop PC, Asus X99 - Deluxe. It doesnt power up, and died during a power surge. Im still watching your videos to try learn enough to try see what is bust on the MOBO. Love the channel! thank you!!!
I gotta say thank you very much man for teaching me repair, I found rossmann a little hard to follow when it comes to his repairs so I have been binge watching you last few weeks or so and ya thank you
If you replace mosfets on a badly designed laptop. Won't they just blow again? We don't do board repair where I work...we'd have to charge a couple hundred dollars for a repair like that if we did...no one would want to pay that to repair a motherboard. Keep up the good work and good work on the channel.
a dead mosfet doesn't mean a laptop is designed badly, a mosfet is essentially just a switch, you can have a multimillion dollar house but that wont stop a light switch from failing eventually
Weller Soldering station He has a link in the "show more" of everything he uses help support the channel. He also sells the flux he uses and has a video on the tips he uses. The proper flux is the secret sauce.
I also suspected the 2nd MOSFET because it shows the short in the meter reading, I would have take out that MOSFET for further inspection... thank you master once again 🙏 ❤️ you taught me well...
i just completed a form to have you guys maybe look at my laptop. i followed along with your video, and i suspect my mosfets are bad as i am getting very simliar data points you had in this video. is there a ball park figure for repair of this type?
@@SiETechNotebookReparatur agree therefore VG is > or equal to Vout + Vth. I am thinking there is a boost circuit on VG since he measured 20V from the DC supply and on the source to gnd.
@@ziradlabs You can find all such information in the datasheets of Charger IC´s. The gate drivers are internally integrated into the IC with 6V of gate drive voltage. Most charging ICs have 2 charging pumps for the gate-drive.
Hello there, Thats a very usefull video that i enjoyed. I got one question: When you dessolder the mosfet what temperature and air force do you used? Thank you and carry on👍
Yet another superb video, thank you Alex (and Big Boss). Can I ask though please, what made the mosfet overheat? Could there be a fault of some description further on causing over current?
Yes, in this case, Alex should have turned it on and looked at the mosfet with thermal camera. There could indeed be an un repaired fault downstream that was the original cause. He seems to think that there is always only 1 problem.
If i remove the HDD and put that in the dvd place by caddy and put the SSD in the the HDD's place, Can the laptop's motherboard be damaged in the long run.?
Makes me feel like some of these laptops have overheating problems or something, because they so often have power issues. I have an Asus zenbook 14, and it's a wonderful laptop, but I wonder when it's going to have a power issue now...
I've seen you repair hundrends of devices, and one thought came to my mind, just out of curiocity, approximately whats the percentage of the devices that can't be fixed? Can you share that information?

Aí quando o componente voa pra longe tu tem que dizer "It went to the 9th dimension".
This feeling when I manage to repair a device is incredible, so proud and full of satisfaction !
Great to see you smile at a good fix. Biggest buzz in fault finding for an Electronics Technician/Engineer is to crack the mystery. Well done again.
Your smile after a repair brings light in our dark hearts
I love how happy you are after fixing stuff.
Thank you for the seasonal sparks. 🙏😀
I fixed the same problem on asus notebook recently (thanks to you) and must say, you have incredible steady hands.

One of the Best videos You have. Because You show how to check the parts
Love the smile after every repair. True dedication and passion for your job.
I love that too, because it reminds me of the big goofy smile on my face when I finish any solder repair.
I've colleagues that would do the same, unfortunately they never smile.
Excelente diagnostico gracias, saludos desde PERÚ 🇵🇪.
how is he not on 1 mil subs yet love ur videos
Salute master i enjoy every videos you share😁😁😁👍👍👍👍
appreciate the detailed comment about mosfets.. im learning how to measure mosfets.

Exactly! 😀
True,he make it look simple but it need lot of experience it you think about it.
Thank you for your videos Alex!!
Knowledge is power~!
I love every content that you post idol!
what a discovery you made ! I'm not surprised that your videos are 10 minutes long only. 😁
Everyday i see you're videos and i enjoy. Thank you so much you are amazing in electronic repairing.
Good luck 👍
Wow. I'm impressed. My GL502V just took a poop.. doesn't want to load windows or repair. I'm hoping I can save myself from needing a new laptop.
Love the step by step methods , BTF
After watching so many Asus repairs i do not think i will ever go and buy one. Another great repair!

@@em0_tion Right, In my country, Asus has a pretty good reputation, it is HP specially their pavilion models that's a no go.
@@sidewinder3422 I do not remember the last HP pavilion repair at Alex. He mentions it himself that every single day has Asus laptops on his desk.

This is awesome video. Now I just have learned about mosfets. Thank you so much for sharing.
Love watching your vids here in uk 🇬🇧 keep them coming
Every video I become a better teqy. It improves my deduction skills.

thank you my God for this brother.
Excellent job
valuable as usual , thank you bro , all respect & love boss
Excelente video
Another job well done, yes, always look for tell tail signs.
“Welcome to the world of MOSFETS” - I’m definitely stealing that line.
Awesome job bro keep rocking bro 👍👍👍
you are amazing. straight forward.
Thank you for your videos. Really helpful and i enjoy the content. God bless
Good explanation of how to test mosfet
thanks you verymuch... from lampung indonesia
I gotta say thank you very much man for teaching me repair, I found rossmann a little hard to follow when it comes to his repairs so I have been binge watching you last few weeks or so and ya thank you

Thank s for sharing your knowledge.
Very good!👍
That's exactly what I wanted to know! Thank you so much
Thank you sir I learned a lot
It was very useful and informative tutorial video . thnx
I see what u did there is already christmas so why not some sparks nice one 🥳
Appreciate this info greatly,,,thank you
شكراااااااا على المعلومات القدمة
I don't even need to wait for you to say the laptop is fix because your smile on your face already said it
Nice vídeo! Thank's.
ممتاز جدا اتعلم منك الكثير من المعلومات القيمة وبطريقة رائعة .قناة مشوقة و جد رائعة
Hey Alex really love your videos. Which soldering iron you using? Can you make a video on soldering iron please?
Weller Soldering station He has a link in the "show more" of everything he uses help support the channel. He also sells the flux he uses and has a video on the tips he uses. The proper flux is the secret sauce.

very nice repair
You know why I think those MOSFETs fail so often ... lack of proper heat sinks.
Not enough margin on the current rating maybe? Steady state vs in rush
Good test
Good job
Happy to have bought an MSI. Does he specialize in power problems with ASUS?
thank you teacher
i just completed a form to have you guys maybe look at my laptop. i followed along with your video, and i suspect my mosfets are bad as i am getting very simliar data points you had in this video. is there a ball park figure for repair of this type?
impressed
well done
Please can you also show where you exactly put both meter lead
Is the factory flux a reasonable quality?
Good to know
Good Job
Hi sir, did you meassure the mosfet with adapter plugged on board? i mean does it have power?
I've enjoyed the video
Beautiful
thank you sir
Can you confirm what was the Voltage on the Gate on the first Mosfet, after you you got it working? Many thanx
By N-channel mosfets, the opening voltage at the gate should be 6 Volts higher than the input Voltage, also about 25 Volts here.
@@SiETechNotebookReparatur agree therefore VG is > or equal to Vout + Vth. I am thinking there is a boost circuit on VG since he measured 20V from the DC supply and on the source to gnd.

I have same problem. Same spot on Asus.. but I need to buy parts, where can I find some of those mosfets
Why dont u use dc pwr supply ?
Was it heat that killed the mosfet I guess?
Doing gods work sir 🙏 thanks for the video
