WOW. for the first time I have seen someone doing theory nicely and getting people to understand what is happening as he does the practical.
1Q
Yeah first time indeed
@@funnelcreations さし
Wow
apparently you don't know other channels like this one
I am studying Computer technician in my country and I'm learning a lot from this guy! He shows a lot of techniques in identifying common issues and some I haven't encountered yet. I gain a lot of wisdom and knowledge by simply watching his videos. Kudos to you sir!
I have been repairing electronic gear for 50 years. You make me look like a beginner!
the amount of calls coming from the customer being so vague about their laptops, imagine the amount of work he takes a day lol. genuinely love this type of work
You are very thorough yet efficient with your explanations. Very much appreciated!
I've been doing electronics work since I was a kid going with my dad to his TV repair shop, spent 20 years in the military as a radio tech, and am now nearly finished with two associates degrees in electronics/electro-mechanical systems, and I learn something new EVERY TIME I watch one of your videos. Love your work and channel my friend!
Nice work.
WTF? u work 20years with electronic and have two degree, but u did not know what knew somebody with BASIC electronic knowing?
Did u sleep all your work and two degrees?
@@danielsatko You must be real fun at parties.
@@AmadonFaul not as funny as u 🤣
Thanks 🙏🏻
Same since I was 3 yo.
This guy really knows what he is doing.Unlike other guys on yt that do it by trial and error ,or some others that already tested the device before making the vid and knew the issue but are acting like they didnt. Keep up the good work, I am learning a lot from you.
Thank you for your very clear explanations where you talk to people like they don't know anything and you repeat the concept a few times so they "get it." Some people teach like the student knows what they know, and it's hard to follow. I have fixed analog electronics in the past but this video really gave me a much clearer understanding of how to go about it on these digital laptop circuits with these microscopic surface mount components!
This was hands down the most informative, clear, understandable tutori for throunleshooting motherboard issues. Thank you so very much sir, you do awesome work!
Awesome. Your videos are short and brief, whilst containing the crucial skills and knowledge in pinpointing the exact issue and solving it. I've learnt alot in such a short time in comparison to other 1 hour long videos from other uploaders. Because of that, I've subscribed.
Just wanted to say thanks for all the videos. They are very informative and the way you explain things really resonates with me.
Now a days I'm watching your videos daily. And found them the best repair videos on TH-cam.
Nice guess on the bad capacitor! It looked a little bit de-laminated, but hardly discernible even with a microscope. You could have replaced it with a 10nF capacitor, just to provide some local noise filtering. It is a conservative value, as 100nF is a typical value for those.
The way you explain and work watching it happen is so satisfying i can watch you all night repairing stuff
You are truly gifted my friend. I love watching you work.
Ill be mailing my computer to you. Awesome work!!!
Great job as always, keep up the good work, and thanks for the thorough explanations! I am always learning alot from you and always look forward to my "daily lesson". Regards
Loved the commentary as you diagnosed the fault. Thumbs up and subscribed.
What an excellent video! Logical, step by step approach with mind-blowing techniques through razor-sharp tools.
Naaah. Standard procedures and trouble shooting.
No Biggie.
Love the way you explain the workflow. Thank you!
Educational :D & Helpful :)
That was fantastic to watch. Thanks for taking the time to show us your skills and knowledge.
Learn a great deal in just the few minutes. Thanks robert Y
Seriously one of my favorite TH-cam channels.
From me too
Always a pleasure to watch a pro at work
You make it look so common sense and easy. My hat's off to you.
Wow wat an explanation n I have total respect to this guy the way he explain his theory n does practical on electronics. This guy is an electronic encyclopedia
Man you are a crash course for beginner Sauder I appreciate how you detail your walkthroughs way better than just speeding up and adding music. Thanks for your dedication and details. Quick question what is that brown mesh your using to clean the board?
Quite a learning experience towards how MOSFETs work.
Awesome work man! Thank you for this great video and the lesson!
Today I just got luck to visit your video, video was good. I haven't watched the way you have explained over the youtube. Something very correctly understandable. I think your explanation way will definitely make me to watch your all videos. Keep it up. It's all new to me. Thanks
I actually have that electricity feeder. Just short one flir Camara got the whole kit to start fixing again, your videos are a great refresh update on new methods
I actually learned from this video . Way better than those cartoon videos with computer voices . Thanks for all your videos .
Love your work, detailed and knows what he's doing and explains each chip.
Stay safe and Keep it up
I learned more from you.
A true passionate electrical engineer.
waww.this is the 1st time I see such mosfet.thank you
I like how you explain mosfet work, and what causing short by capacitor and resistor not causing short. Keep smile :)
That was such a neat piece of work, you remind me of my computer maintenance teacher, he's so genious like you. Thank you for sharing your experiences.
My God! What a nice microscope you have, buddy! The video quality is outstanding!
Excellent repair! Great to watch. Thanks a lot.
A very good experience 😃 takes you as quick as you get the repair ✅ done
Damn man... You make it look so easy....great job ... Congrats 👏👏👏👏
Your solder skills are as impressive as your diagnostics. And you take pride in your work. Thanks. Have a few “dead” old boards am going to play with but only for learning. Plus keeps me from HDL wife keeps piling on 😏
One of the most informative channels around. Thank you, sir.
Wow, well explained my friend, it clears my doubt in somehow related issues on board thanks for the clarification. More power sir
Very good analysis sharp, quick and brief.
Freaking awesome man! I now wonder if these strix's inherently have this issue or are common to result in a blown cap, starting with a weak charging port receptacle. I had the same thing happen to mine... Thanks to your video, I have hope in troubleshooting/fixing this.
Good stuff mate.. that was cool I actually understood and followed what you were talking about
Very very helpful video. I found the schematics of my laptop (ACER) on Internet for 5$. 1 diode and 2 capacitors in short ... now repaired. Thks a lot.
can you please name the website if you don't mind? thanks a lot.
Oh man i Like The Way You Fix the Things 😉 May God Bless you
Your video tought me more, faster than the previous 100 combined.
Awesome. Can't wait to start diagnosing my 14bis HP board. You make it look fun.
Loving the troubleshooting steps it gives me motivation. Thx
A great vid, very informative, you're the man...bravo !
you so professional bro! i hope i can learn more from you
HELLO NORTH! Am an avid Subscriber, you are my first 'Go to' when diagnosing PC issues! I recently built a new Computer in my old Tower with a new Raidmax Vampire 1000W 80 Plus Gold Power Supply, an MSI Z390-A PRO Motherboard with an Intel Pentium Gold Processor G5400 CPU @ 3.7GHz! Next added 64.0 GB DDR4 3200 Ram! Also a ZOTAC GAMING GeForce GTX 1 Video Card! Recently upgraded all my HHD's with an Intel 660p Series M.2 1 TB SSD Drive C and two WD I TB internal SSD's! My Computer now boots up completely for a cold start in 30 seconds!!!! (Once in a while when I turn it on, it Boots into the Bios Screen)!!!(But when I wont to boot into Bios, no matter what key combination I press it wont go into Bios on Command)! Windows will not display on my Digital Monitor but I can see the Bios Screen on another HDMI Output to my 32 inch TV! Am running XMP Mode and Gaming Mode on the MSI along with allocating 3/4 of my Ram to Process my Adobe Premiere 2022! My Question is: How do I get the computer to Boot into Windows EVERY TIME? And secondly, How do I get my computer to boot into Bios on command?
Absolutely stunning video! I am very happy with you media.
A great vid, your approach is very pro, bravo !
Thank you very much for this video. It's very helpfull even your techniques. Great job and no commercials makes this video perfect. Very nice!
I’ve just found one of most useful channel in TH-cam.
Great explanation and step by step process showing how to determining power issue!
amazing skill and effort!
so professional
IDK. leaving that cap out is not by the book professional but we all have our time saving tricks I guess..
@@Elfnetdesigns would it be possible to know the value of that capacitor without more info about the circuit? how would you replace it?
@@StromboliKicks I would get the schematic of the device. They exist and some are free others you have to pay for.
I am an ELECTRONIC technician I give you respect on practical, you are great.
one of the best videos in this channel , thank you
Hi! your video on troubleshooting is easy to understand and get more knowledge on repairs, thank you and continue upload more videos.
freakin' awesome... I could watch these all day
Good job Man, with easy way you have explained everything
Wow the best board troubleshooting I ever came across. Gracias!
Very intuitive diagnosing protocol. Impressive.
I, too, have a Asus rog gl552vw with puzzling symptoms:
- when power connected, the front light for power and battery charge are on but it doesn't boot
- if only on battery, no lights on, no boot
- when I leave it, plugged or not, the area on the left of the pad becomes quite hot until I remove the power cord and the battery...
Any idea, somebody ?...
Thank you
Thumb up for a very useful video, well explained and well realized!
Hello Sir, I want to say you're an inspirational person, your work experiences and way you explain is like no other, your craft is unmatched due to your amazing humbleness and relaxed approach. Truly wish you the best and hope you never change. My favorite Channel, Tell Big BOSS to do recognition award video, you deserve many.
Good job Habibi , found it very helpful :)
One of best videos!
In most videos you speak very fast
Great one.
Stay safe
Woooww thanks man for the amazing video. The best technician so far!!
Great fix,very analytical and thorough. Tku
Thanks so much for the explanations! Had my laptop fixed at a local shop and having no knowledge about circuits I was dumbfounded with his lecture about mosfets and capacitors... This video really helped me understand. Thank you!
Great to hear.
@@NorthridgeFix Sir... I have a question and I really need your answer based on your experience. I was using my netbook for about 5 minutes after that it suddenly turning off and smoke coming out of the charging port, I immediately unplugged the adapter from the netbook. After that, I waited 1 hour and tried plugging the adapter back just to see if the charging port indicator light is still on and yes it's still on but I'm afraid to turn on the netbook. my question is... does my netbook still have a chance that there will be no serious damage to its components or not?? sorry about my english ...
Well done!!!! You could solder the culprit back to check to see if you do see it on thermo cam
Thank you for your hard work professor ❤️
thank you from France
I like this video. I need to learn how to fix it without circuit diagram. This is a good source to learn. I will keep watching video.
Thanks I been on this channel 2 years. And so many videos unseen yet
I like you work! Great job! Is this honestly worth it though, with the cost of laptops being so low now? I have a laptop that I may have to send you, but I'm curious as to what a job like this cost?
Brilliant combination of theory and practical 🥳🥳
thank u very much that was helpful
Some people gave thumbs down...?, what's not to like about these videos? Keep them coming.
Ny guess its cos he used too much solder on the mosfets. Sure the pins are the same but you want a proper finish.
probably the competition hating on the Professor and Big Boss lol
Trank you very much for teaching. Good Job mate
Thanks for sharing videos and your practical experience..i think this channel is more usefull than any other..fast and perfectly understandable
thank you bro from France!
Great... thanks. Very informative. You have mentioned the key points to troubleshoot
Great video bro, thanks for all the explanation s, great teacher.
Just my 2cts : when using FLIR - do not use laptop PSU, it will shut down, use a lab PSU instead and start with 1-2 Volts, this will give you about 3 Watts of heat on your defect cap, which will show nicely on your FLIR.
Nope! It doesn't always happen that way. If capacitor is completely in short It doesnt warm.
@@renatosaraivalima I've had dead shorted caps that show warm. Less than 5 ohm. Why do you say that a completely shorted cap won't show warm?
Hello i have asus x550vx laptop it has same problem in this video laptop how i fix it (no power not charge)
@@user-ty2uz4gb7v completely short, ZERO ohm. Meter shows near about 0.23ohm. ALL laptops that I fixed with ZERO ohm caps over 1.2v, 3.3v or 5.0v lines, capacitors never warmed.
what i was about to type out, good on you sir!
Great job again like always
You got the skills man nice job!!
Great job , you must title this : Basics of detecting a faulty capacitor
nice, happy new year i love this channel
Way to go. Awesome diagnosis.
Great job. By seeing this video I have fixed my college Asus laptop which was not turning On even with battery or charger. I just removed one tiny mosfet near by charging port. I found that surrounded area capacitors shows short to ground. Once I removed tiny mosfet then short has gone. I do not have a same mosfet so I decided to jumper its drain and source pins. After I assembled everything I checked laptop and wola it's working fine and charging too. Thanks for guiding through your videos.
Owais Akhter by jumping it thereby bypassing the mosfet’s function, if the situation happens again, won’t it blow your motherboard?
@@barbara82589 I knew that if the situation happens again then possibly another mosfet would fry also and could damage further towards supply rail or power management circuitry. For that reason I have added 2 Amp smd fuse in series leading to mosfet. So in case if charger cable short again from its positive to ground or laptop draws 2 Ampare because of anything wrong with charger then 2 Amp smd fuse will below instead of whole power management circuit goes blow.
What ASUS model do you have? Seems to be a somewhat frequent ASUS problem. Mine is a Q324U. I wish they would have used a harness connector for jack component instead of solder type, easier to test and swap out for those of us without soldering skills
@@barbara82589 I'm sorry I don't remember the exact model now but I will update you after ask my colleague. But I'm not pretty sure that it's frequent problem with Asus laptops. In our case charger cable was torn and by mistake it was joined reversed polarity. Once he connected charger just after cable repair then within 2 seconds laptop shuts down by itself.
Some laptops I have found small charger port PCB and some harness connects that PCB to Mainboard. So repair might be simple or requires replacement of charging port PCB only.
Thanks for the explanation.!!! I have a question for you, can I jus put a jumper wire from drain to source in order to make it work ?
Awesome I’m glad I found your channel. Very educational
You are really awesome man.love your work♥️♥️♥️from Bangladesh dear.
Amazing troubleshooting dear. Superb. 👍
