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.
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 ...
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.
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
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 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 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

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?
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.

Hey Alex, you should upload your SMD component diagrams for each console/phone/laptop on your website. Would be very helpful. In other words, the values of each component from a working motherboard.
Hi there, I have a similar issue with my asus laptop but my mosfet part number is M3056M 630 03E. What does the 630 03E mean? I cant find exactly the mostfet with the 630 03E

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 !
Your smile after a repair brings light in our dark hearts
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.
I love how happy you are after fixing stuff.
I fixed the same problem on asus notebook recently (thanks to you) and must say, you have incredible steady hands.

True,he make it look simple but it need lot of experience it you think about it.
can't thank you enough for the knowledge you provided an industrial electronics engineering student like me !!
Thank you for the seasonal sparks. 🙏😀
After watching so many Asus repairs i do not think i will ever go and buy one. Another great repair!

One of the Best videos You have. Because You show how to check the parts
Every video I become a better teqy. It improves my deduction skills.
what a discovery you made ! I'm not surprised that your videos are 10 minutes long only. 😁
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...
Alex, thanks for the troubleshooting guide, steps, insight, and conclusions!
appreciate the detailed comment about mosfets.. im learning how to measure mosfets.
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
“Welcome to the world of MOSFETS” - I’m definitely stealing that line.
I don't even need to wait for you to say the laptop is fix because your smile on your face already said it
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.
Happy to have bought an MSI. Does he specialize in power problems with ASUS?
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
Everyday i see you're videos and i enjoy. Thank you so much you are amazing in electronic repairing.
Good luck 👍

دائمآ فيديوهاتك ممتعة 👍🏻
Another job well done, yes, always look for tell tail signs.
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.

After watched this video, it made me curious about how did big Boss test and confirm that cable charging was not in production mode?
very nice repair
Thank s for sharing your knowledge.
Was it heat that killed the mosfet I guess?
Why dont u use dc pwr supply ?
always I watching your videos , perfect

When a component on the board get shorted, voltage pass through it and goes to the next component on the board. Why the next component didn't blow up?
