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.

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!

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

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.

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.

This was hands down the most informative, clear, understandable tutori for throunleshooting motherboard issues. Thank you so very much sir, you do awesome work!

good day alex thank you for adding words on the screen when you are repairing a device,my son kyrian venter is deaf and he cant hear,so now its much better for him to follow your prestine work,thank you for that we are from south africa in cape town strandfontein,we watched all you videos so far and gained alot of knowledge from you,we appriciate the effort you put in to this channel,a shout out from me arrie and kyrian from cape town south africa

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!

I have been repairing electronic gear for 50 years. You make me look like a beginner!

You are very thorough yet efficient with your explanations. Very much appreciated!

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.

Now a days I'm watching your videos daily. And found them the best repair videos on KZfaq.

A true passionate electrical engineer.

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?

I am an ELECTRONIC technician I give you respect on practical, you are great.

The way you explain and work watching it happen is so satisfying i can watch you all night repairing stuff

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.

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.

Just wanted to say thanks for all the videos. They are very informative and the way you explain things really resonates with me.

Seriously one of my favorite KZfaq channels.

You are truly gifted my friend. I love watching you work.

I like how you explain mosfet work, and what causing short by capacitor and resistor not causing short. Keep smile :)

Some people gave thumbs down...?, what's not to like about these videos? Keep them coming.

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

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.

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

Your video tought me more, faster than the previous 100 combined.

I actually learned from this video . Way better than those cartoon videos with computer voices . Thanks for all your videos .

One of the most informative channels around. Thank you, sir.

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!

I’ve just found one of most useful channel in KZfaq.

Best channel on utube hv ever washed you show everything I will wash u till I be like you.God bless you sir...

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.

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

Nice informative tutorial but here is a thought: Voltage injecting 19v on a faulty board seems really dangerous. It could damage even more. Why not hooking it up to an external power supply, limit the voltage to 5v and limit the current as well. This will prevent the inrush limiter to kick in and you can still use the flir camera. What do you think?

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?

Always a pleasure to watch a pro at work

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!

Quite a learning experience towards how MOSFETs work.

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.

Damn I'm impressed what you're able to do without a schematic

What an excellent video! Logical, step by step approach with mind-blowing techniques through razor-sharp tools.

One of best videos! In most videos you speak very fast Great one. Stay safe

Thanks I been on this channel 2 years. And so many videos unseen yet

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.

Learn a great deal in just the few minutes. Thanks robert Y

First of all, let me introduce myself. I"m Jadi from Indonesia as a Begginner PC/Laptop Technician. Btw,Thank U to share the Valuable Technical On Repaire the Laptop.

Love the way you explain the workflow. Thank you!

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 😏

You make it look so common sense and easy. My hat's off to you.

Loved the commentary as you diagnosed the fault. Thumbs up and subscribed.

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

Nice job brother I like your teachings from Mombasa kenya

Impressive! Informative, with the minimum of useless chatter. Thumbs up and subscribed.

Ill be mailing my computer to you. Awesome work!!!

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.

Probably the best explanation of how MOSFETs work in real life.

You re the man! I think I'm gonna be a electronic technician

You can inject 19V to the 19V rail w/o damaging but you MUST use a power supply with variable current limit, cranking the current slowly up. The thermo camera is a good idea if you have it, otherwise use your fingertip carefully not to burn yourself. Using serial connected 24V or 2x12V automotive light bulbs for current limit is a cheap solution if you do not have a power supply with variable current control. The bulbs can be 15W, 25W, 45W 55W depending on the desired current.

This is eye opening.... I got similar problem, now i know.. not all the all the cap need to change.. If Shorted.. There is should be one cause everything..

Hi, You can put a little bit of flux on a suspected short component and draw the current; if that is short the flux will vaporize. This is also a manual method of testing short component like puting on a finger and feel the heat as we know this is a low voltage circuit. Good luck..

You started with a frightening scenarios of shorts and narrowed it down to one 'bad-guy'. Excellent detective work. !!

I can learn a somethng here. This not 100% can be work for all laptop. Which mean, it can be different for another laptops case but I understand every what his said and we need to check every parts with the multitester. The conclusion is, check the shortage, if components is a different than usual from another for the same type like hotter, no power or discolored, mean that was the suspect. We need to remove or replace it then plug back the power source then see how it goes. Thank you for sharing :)

Love and respect from LIBYA 😘😘😍😍

Hi! your video on troubleshooting is easy to understand and get more knowledge on repairs, thank you and continue upload more videos.

Sir you have really good instruments & tools for repairing, & process of work is really nice,but you can fix this at only 2 minutes by injecting volt with high amp to the second mosfet & detect faulty capacitor by hand... Sorry if i hurt you... Thanks

Great job , you must title this : Basics of detecting a faulty capacitor

My God! What a nice microscope you have, buddy! The video quality is outstanding!

you so professional bro! i hope i can learn more from you

Brilliant combination of theory and practical 🥳🥳

Danke, Fuer Ihre Hilfe.

well explained ! Top job -thanks!

Great explanation and step by step process showing how to determining power issue!

Good job Man, with easy way you have explained everything

Absolutely stunning video! I am very happy with you media.

amazing skill and effort! so professional

Woooww thanks man for the amazing video. The best technician so far!!

freakin' awesome... I could watch these all day

Awesome. Can't wait to start diagnosing my 14bis HP board. You make it look fun.

Wow the best board troubleshooting I ever came across. Gracias!

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.

Pls Multimetre value show on the side of the screen

That was fantastic to watch. Thanks for taking the time to show us your skills and knowledge.

Great fix,very analytical and thorough. Tku

thank you from France

Your great technician thank you very much sir for sharing your knowledged💖

waww.this is the 1st time I see such mosfet.thank you

Loving the troubleshooting steps it gives me motivation. Thx

❤superb great 👍 xcellent 🎉 Alhamdulillah watching you from Bangladesh 🇧🇩 I have learnt something

I think it would be ok to apply low voltage/cc directly to these suspicious caps, would make it easier to pinpoint the shorted part. Also it looks like you chipped off a bit of capacitor at 9:39

Well done!!!! You could solder the culprit back to check to see if you do see it on thermo cam

I love you Northridge , from Congolese

We are blessed to have u sir thank you

Dude! Such wizardry!

A very good experience 😃 takes you as quick as you get the repair ✅ done

Thanks for sharing videos and your practical experience..i think this channel is more usefull than any other..fast and perfectly understandable

Very good analysis sharp, quick and brief.

Yes thanks for the information I appreciate that I'm also in iT now too.

one of the best videos in this channel , thank you

This video is awesome! Thanks for sharing your job. One question, how many celsius degreess do you normally use for removing/adding smd components on the motherboard? :)
