The best thing for me is the fact that you are humble and you don’t care to show that this one was fixed with someone’s help, even though you are one of the best out there!!
Massive respect to you for never giving up on solving the puzzle, reading comments and trying something new to fix the puzzle, then for giving a shout out to the person who gave you an idea to try and it worked. Big respect and Hello to Big Boss.
Way to go Alex and Michael. This is truly a community, like Alex said, learning and educating. In the end... a happy customer! That is what counts the most.
This is one of the reasons I support this channel you are one of the best at what you do and you're not up your own arse and listen to other people great job keep it up 👌
This is a good example of why I love the internet. The sharing of ideas over great distances, often times in ways you don't realise. I'm sure the owner will be grateful to have that laptop back in service, and now you have another tool in your box to use in future repairs.
I am not literate in electronics but I always like tol earn and solve problems by myself and i kept on googling and learning. I found your teaching interesting and the way peoples learn from each other.Intersting, thank you for all your jobs.
Alex is not alone, there's a whole youtube community for Northridge Fix. Appreciate both Alex and Michael. This community is one of a kind and the best😘.
Makes sense when you think about it. The only time a manufacturer would use 2 MOSFETs in parallel is if the current load is over the capacity of single unit, therefore when one fails it also takes down the adjacent unit. Replacing one only just leaves a working MOSFET which cannot handle the total load, therefore it blows again. The fun part is while the normal failure mode is to fail short, one didn't.
@@reeldeelz2940 Basically there are 3 terminals, if all 3 have continuity between the 2 MOSFETs then they are connected in parallel, and therefore if one has failed, it is safe to assume the second has. In the case with Alex you can see the tracks join both MOSFETs together in parallel. It's safe to assume every manufacturer is cost oriented, there is a reason for every component, if they didn't need a MOSFET it wouldn't be there, sure they could use a higher power unit, but if 90% of their needs are the lower power ones they get a good price on them and it would be cheaper to use 2 in parallel than buy a relatively small quantity of higher power units just for one model.
@@reeldeelz2940 gate drain and source are connected in parallel, measure 0 ohms. If the laptop would power on by only removing the shorted mosfet, the other one is still functional. If not then the mosfet also failed but just isn’t shorted.
Greetings to the community. Thanks to Michael and Alex for sharing. Great job. I must confess that at first I just could not understand why the second mosfet would be affected given the parallel configuration. However, after reading the comment given by a commentator, I realize that it leads back to basic electronics where the sum of the currents in the branch circuits is equivalent to the total current produced by the source. Therefore, each mosfet would carry just a portion of the total current and would likely be affected collectively based on their configuration. Thanks guys. Be blessed.
This video has helped me out also! I had 2 hp laptops with same sort of issue and replacing 2 mosfets also worked out. Thank you Michael and thank you Northridgefix. Repair would be a nightmare if we didn't have the community as you say!
Awesome stuff! Great that the community can all come together to get these devices fixed and back in the hands of people who need them. Kudos Michael! :)
Your very humble. Not like most people you actually give credit to the person that helps. Also shows your character most techs think they know it all and won’t take advice you on the other hand take the advice and learn / remember from it and fix the situation good job Michael and NR
I'm a new viewer been watching a few months now, I have recently sent an iPad to you for service because of your channel here I have no doubt you can fix it, I've spent years working on a bench and seen many good techs however I have too say your trouble shooting and soldering skills are nothing but pro, not only do you make it look easy, your temperament willingness to have another set of eyes suggest ideas is another great sign of your skills, another words you know you can never stop learning no matter the level your at, keep the videos coming love them btw I agree better than factory needs to be on a t shirt, R-
The two mosfets work like two cranes: they need to work in perfect synchronization: if one mosfets is slower than the other one means that one mosfet takes more load causing it to be overloaded.
Awesome job. Great on you for reading and listening to your subscriber. Goes to show not everyone even professionals know everything. And you didn't let pride get in the way, followed the advice. And got a fix.
Your channel is really the best of all "fixing"-channels. I love your work. And i love it when you read the comments and listen to your great community. Amazing. Great work. Great video. Thank you, greets.
Well done Michael, and well done you Alex for scouring the comments, and finding the solution. It would have been a shame to deem it a no fix, I always love a happy ending. 😊
Very professional and informative video. Not like the others that spend 3 min to tell how 100 ways to give them money and then just "show off" for hours with crude commentary.
Sharing knowledge is caring , it is like this we evolve and learn more , the very reason you make videos is to share your knowledge with us, so it is no surprise that we , your fans and followers, will also share anything that might be helpful .... Glad it fixed the problem , and today we will sleep less ignorant ;)
I was gonna say use your thermal camera on the other video, but Michael made a great suggestion, you listened and you fixed it without the camera. Another good tool in your experience bag for the future to be more efficient and to make more money on the job than a diagnostic fee only. 👍
Your every content = knowledge package 📦👏 thanks to all for working as a team and specially to the one who are always helping others that's makes him the real human being 🖤 Great !! Keep going 💓 LoveFromIndia!!!!
This is a great channel! We learn and then give back :) Just shows how sharing is important for both sides. BTW, very hot components (+200C) can behave differently especially semiconductors. For example MOSFETs can be opened (drain, source low resistance) even though no gate voltage is supplied.
To say I was excited to see this video pop up after the cliffhanger that was the last one is an absolute understatement. This right here is an example of why Alex will continue to be successful in all his business ventures.
Was thinking of purchasing a thermal camera, but have decided to buy a Michael instead. Any update on when Michael will be for sale on the NorthridgeFix site, Alex?
Great Video, You always amaze me, and this time you have shown me a need side of yourself and your community that is wonderful. Helping each other learn...how awesome....Thank You : )
The first mosfet was bad, shorted, however the second one may be bad, open. Remove the shorted one and the short goes away, but even when the shorted mosfet is replaced, it gets no assistance from the bad open mosfet, so it over dissipates, and blows immediately from handling all the current, instead of just half.
Sometimes a mosfet will blow but not show any symptoms. I had a item have one hot mosfet when it failed. Replacing it just made it hot again. I checked all 4 mosfets and they measured ok. So I replaced all 4 mosfets and that fixed the problem.
The case of 2 paralel mosfets burned partially ou all in computers is known also with tranceiver's final HF power amplifiers on two or three models of CB tranceivers (Ham international for example) equiped with 2 final power amplifier in paralell. When one of the two PA of the tranceiver is burned, you must change the two PA because if you change only the bad PA, the second PA wich seems good will die quickly after... Then you fix the problem... Thank you for all your very interesting videos.
Mike saved the day and the asus from the landfill! It's time for Alex to pull up the older similar no fixes and see if it had the same issue. Anyways, I think he would have used the boards for spares by now.
Alex Nice job it looks like you have a full control of the hot air and tweezers are you holding the Air in your right hand or left can you show some tricks how to get control on the air and tweezers when replacing component Thanks
Alex can u test finding a short using thermal paper. The paper that turns black when subject to heat. Just wondering if that would work in locating a heat spot on a board.
I am a medical doctor from Pakistan but have enthusiasm for electronics, I really like watching your videos, I like that you read the comments and act on suggestions which you think may fix the problem, are you Muslim?
How on earth does Alex/Northridgefix find the time to fix all the devices, run a business, film and upload videos, read the comments, search for a new home and a shop, be with the family, ect?

i'm glad to helped 👍👍 nice job to all
perfect
thank you , big boss
Greetings Michael. Thanks for sharing. God's richest blessings to you and your family.

I was just about to say the same thing
We are all learn from each other ☺️ انت معلم كبير
No video
Agree
well done michael ..you obviously know your electronics ....like alex says everyone is always learning even him ....thank you .

Is there anyway to detect that is the case prior to replacing one of them? How can one know beforehand that they are installed in parallel?
Still dont get it: if both parallel lines are dead, why the second mosfet read OK when the first was removed?

Nice job Michael!
your video helps me a lot to diagnose lil bit electronic fault, easy to understand straight to point and nothing to hide. i'm very thankfull sir
Wow!! Happy to see even the experts will always take on other people's suggestions and helpful advice. Excellent work!!!!
All hail Michael! And bravo to you for humbly accepting a fix suggestion from a follower. Just goes to show that you have nature. Great ending!

Yup, that's why we don't take measurements while the board is hot.
I watch as many of your videos as I can I am learning so much thank you.
Love the new (old) camera angle ;)
It's not very often but this time I love TH-cam and it's community!
Michael deserve a reward

Best comment yet 😂
He's getting his first shipment in 9 months Michael's Mum says.
I think if you ask nicely, you can have Michael in jar. It is diy kit. Unfortunately it takes around 18 years to grow.
@@REVERSE_BIAS 😂😂😂
Wow, both this channel and viewers are enginer, that was so awesome
Good work Alex. Lucky you didn't give up on it.

Awesome ✌🏻✌🏻✌🏻
Congratulations michle
A shout-out to Michael for a great observation skill
Yeey! Shoutout to Michael Black! You saved the day and someone good laptop!
so they are connected in parallel, wow a new lesson learned from this video
As always thanks for sharing your knowledge and thanks to everyone else who shares their own knowledge. Every day is a school day for everyone.

Wow. thank you Mike
Thanks... lesson learned !
Awesome video series. It really shows we learn something every day.
Well done Michael 👍 unless you look closely at the board they could have been connected in series too.
ولله مايكل طلع معلم ولازم تعرض عليه يشتغل معاك ههههههه عراسي ولله بفتخر فيك انو اصلك عربي واصل لهل المرحله

Well done Michael Black. 😎
Good job. 👍
Thank you Michael
Thumbs up Micheal
i love big boss's comments " معلم مايك " 🥰
Surely Micheal can get a gift voucher for your online shop 😂
Thank you Michael!
That’s great you give credit to your commenters.
PS what language was the conversation with the boss of all bosses?
That was crazy. Thanks for sharing
S/O Michael!!!!
It is good practice to replace the mosfets in pairs and the control driver should also be replaced
Why replace the control driver?
Good job mate 👍
