Q&A Comment Thread (comments I've already answered) Q: You didn't clean the fan. A: Correct, I forgot. I cleaned it off-camera the next day, just before I recorded the 'diagnosing without schematics' video that features the same laptop with a clean fan. _ Q: You should use an IR camera A: Yes. I thought they were super expensive, but I can see that you can get basic ones for about $200 now, which isn't awful. It's on my wishlist. _ Q: Use flux! A: Yes! I made a complete hash of the soldering in this video because I was being lazy. I do have flux and I do use it in other repairs.

Can I just say that your attention to explaining the problem and giving straight forward explanations without any fancy mumbo jumbo that no one understands has made me hit the subscribe button, my friend! It's hard to find someone that can explain something for most people to understand but you're really good at it. I'm away to check out your board repair basics playlist!

These are exceptional. I enjoy the stream-of-thought approach which helps show your troubleshooting approach.

An infrared camera for finding hot components should help...

Bravo, very well executed right from the start to the end. Presentation and method applied to locate the short, spot on. Keep up the work.

Adamant your videos are always educational, entertaining to watch and high quality ! Thank you very much, keep up, you deserve millions subs !

I've been toying with the idea of repairing laptops as a part-time gig. I have a full set up to do proper work, but I lack the confidence to pursue it further. Watching your videos and those of a few other youtubers really helps, so I thank you for your great videos and hope you keep going with it.

Love your work. Goes to show you that you don't need super expensive equipment to solve issues just intelligence.

With your videos, I managed to repair my bluetooth speaker, and I learned loads of things. Thank you !!

One of the best video I've seen on troubleshooting motherboard shorts. Learnt something today. Thank you.

That was awesome. I was thinking,”Damn, going to need a new motherboard.” Then you started probing and fixed it, Amazing!

Dear graham,that was an absolutely outstanding videi.you were very clear precise methodical.and most importantly,you spke slowly and very clearly do people can understand you.. Im an electrician of 20 years and that fault was exceptional. absolutely superb photography too. Please keep up the most superb videos,steve from the uk

Recommended this channel for beginners. Love this video.. Full of tutorial, facts and it really good to enhance understanding how motherboard works.

Watched some of your instructional videos to help regain some hope for my situation. Then while searching for content more specific to my model, I found this. My hope is completely restored.

Even-though, i have a little bit of experience troubleshooting electronics,i have completely overlooked the trick of injecting power to figure out the faulty parts.I remember i used this technique when was in college to troubleshoot the Superheterodyne receivers! Thank you very much for sharing!

Your work is lovable! you saved my life from fault tracing!

Well done Adam, thats so amazing watching you do this, flip.

This is one of the coolest video I've seen on youtube in a long time!

Keep it up my friend! I found your channel yesterday and i've been watching you for some hours now! Thanks for sharing knowledge!

What a great video! Very interesting and educational. Thank you, Adam, for sharing your knowledge.

Hi, I tried to claim warranty on my laptop and they said it was customer induced damage and refused to pay. Long story short I got it shipped back and with the help of this video, I fixed my laptop myself. It was the same capacitor that caused the short too! thanks heaps

Legend...well done...I dont know much about fixing laptops...this has really been an advanced lesson much appreciated

Well-thought out and methodical with good explanation accompanying work. Thanks very much!

so appreciate all you;re lessons and repair videos i am learning so much!!!

probably one of the best videos i have ever seen, greetings from Argentina

excellent thought process , enjoyable video to watch under lockdown, clear video with great content , thanks for sharing .

Very informative piece, the techniques applied are on point. Thanks for sharing the knowledge.

It's not a waste of time to see it twice (it's already in my favorites). Thank you very much for sharing. Greetings.

awesome work! amazing troubleshooting and repair!

I am starting a new school about IT and this is my first time waching this type of video and i have lurnd so muchi in jest this 1 tnx alot you are owsm , keep it up !!

I'm learning so much just watching these videos

Meticulous and intelligent method of approach. Well done!

"I'm gunna turn on the poor man soldering iron.. No just use the good one!" you're hilarious mate, really really good videos, iv just found you, I'm crying out for this kind of information, thankyou!

Amazing repair! Learned a good tip from it, thank you for sharing :D

Flir One Pro needed here, With the cam I’d have found this in about 10 seconds flat. Love your videos though, very educational for people and just the kind of content needed to get new generations interested in proper fault finding

As I studied from learning repair is that as a technician we have to be patient sometimes to get the result before going into wrong further decision which could a destructive attempt to the board🤣. Adamant is very patient in his work. I should learn it.

Omg, I love this guy already, glad I found him, that's one subscriber!

" I tried going a little slower in this video to help people who are learning. " Yea... and u did it right... I'm learning (learning English too :D ) From Hungary

first time I have come across this source of information.... I am very very very impressed....

Congratulations for your great work!. Greetings from Athens Greece!.

Very interesting. Like the flow of thoughts!

Thank you for the video! My Lenovo Yoga 2 13 (symptoms: no power) also had a dead short capacitor near the display connector. However, it also killed the main power controller. Thermal imaging camera greatly speeds up troubleshooting.

great work, thank you for outlining your thought process

that is the exactly repair basic. like other youtubers using thermal camera bla bla more expensive equipments bla bla, and those cannot buy everyone. you are amazing teacher

Best youtube channel I've come across in a minute

I have watched the full 42min video and liked it ... great work .i have to buy myself some good soldering iron someday 😭

I learned something new, I am really grateful for this, thank you.

I had a very similar issue with an Acer Aspire. With your video and easy explantion I was able to find a odd looking capacitor in the cpu vcore circuit. No power insertion needed, just a bit of luck. It was also at the back of the board, while the mosfets were on top. I removed the cap (was kinda welded to the board) and the board was OK! Not replaced the cap. Thanks

trawled through a lot of you videos to find this one No 204 it is exactly the same problem I have on my Dell so I will try following your video again up to the adding power supply and short circuiting wires I call that squeaky bum time ! and as a total beginner as far as I dare go lol

Great bit of problem solving mate

Excellent video. Thanks for sharing.

Fantastic video and very informative. Thank you.

So pleasant watching the British Louis Rossman. Thank you.

Google randomly recommended this video to me, right before I'm about to move to Dorset. Now I know where I'd take my repairs to

Bravo...great explained, step by step, go on...and thanks for your free lesons 😊🍺

It's useful to keep an eye on the voltage when the power supply is in current limit mode. That will tell you how much power you are putting into the board. 3A at 0.1V for example is only 0.3W and that heat is probably not detectable. The only way the power supply is able to limit the current is by varying the voltage.

Awesome video thank you, I found it very educational, and learnt alot from it. Also I thought it was very constructive to the video leaving in the mistaken location of the dodgy capacitor 👍. Cheers Will.

Just like a pro. You are so good.... Good job!!!

I HAVE ENJOYED YOUR VIDEO FROM UGANDA. THUMBS UP.

awesome repair!

Excellent repair!

Always enjoyable.... Thank You

good tech, plenty of professional analysis and patient.. tks frm sharing

you forgot to put the plastc heat shield under the M.2 SSD. Probably not a big issue, but I would have put it back to be sure.

I am from Sri Lanka I really enjoyed this video and very helpful video for me thank you.

Very straight fwd. Thanks man

Awesome content. Thanks for sharing!

My brother.. you amazing me today. After watching 100s of other video and feeling confused. U showed me in 1 video that u know your stuff.!!

Exactly that's what went wrong with my PC since march and I just dump it, but thanks to you cos am gonna get it back to life.

I really appreciate the lesson.

Very good description video, nice teacher.

very nice multimeter gee u don't need a fluke how refreshing...ok ok i have seen repairs go on for days using the quipment manuals, software, even talking to the factory on all types of equipment and may be it will get repaired? this is soo kool to watch you in action...thanks...:) with results!

Wawww i am very interested in the stuff you do and feel im learning a few things watching you, iv subscribed as you give valuable information thanks,

Nice job. Already follow your channel, but I found this video while trying to trouble shoot an LCD TV power circuit and a fragged Lenovo S7 bios. Always love your presentations. I was going to ask about IR cameras, but I see someone beat me to it; they're on my (short) wish list too. I've had my hands on several types and there is a definite difference in what you get for the money spent, but even the cheap ones that you can run off a smart phone would be useful here. If you want a good one for a deal, look into a used or clearance one for a housing efficiency inspector. That's what I'm holding out for. Cheers!

Love you videos, very natural, thanks.

This has been the best clear experience yet of a laptop w/dead short on the mother board. I was forced into a medical early retirement after wearing out joints, pinching nerves, tearing rotator cuff and since July 2020, my 5th lumbar fusion. First in 1987 so much fun! Pain, yeh! I have a Dell Inspiron 15, series 3000, AMT chip Cedar 13283-1 (AKA 3283) that did the same thing after over 3 years of service. I can take your vehicle apart, put it back and run as new. 1 of 4 tool boxes is electrical only as at dealer, I was a 1 man show for a brand they added. Unlucky in a way because it takes all tools to fix front, middle and tail + everything in between. Using a voltage supply and vary the amps allows you to sneak up on shorted part and yes, a thermal camera would be nice. Maybe Santa will visit! I confirm complaint, then diagnose root cause. You did this plus thermal paste. Same used under ignition modules for decades...nice touch! You provided me a clear path to use my Fluke 87 V DMM, limit current, power board and look for warm/hot shorted parts. I always study the schematic to judge where to start for most likely is root cause. Not 100% how to get schematic and Dell #. Using the info under the SDRAM is close, but every time, there 4 more numbers other than Cedar 3283. If you have advice for this X-farm guy who self taught to fix cars, no trying to sell tools, parts and much more. I really enjoyed & will be looking at your videos! Liked, subscribed & saved.

Nice job! Anybody from your audience knows a pc repair man like you in the Los Angeles Area? Thanks for your great videos!

From 9ja, you just earn a subscriber ...well done sir

Very good fix! Thank you!

Great videos, keep them coming

I have the same laptop series but with i3. Its not broken yet :D , but if do, i know where to check. Awesome how you explained how things works :) . Its entertaining and informative at the same times. I might check the other videos as well. Cheers from Amsterdam

Nice to see a true pro at work , not just scrapping the board but finding the fault in the board your a rare breed Sir, just started basic repairs myself example new lap top case new hinges changed up the ram also ssd route on my two laptops, reason for doing DIY getting conned by my local repair shop to often , biggest problem i have had with my large fingers was the two wi fi push on fits question ?????? is there an easy way to attach them . At 74 years old i like things a bit easier Lol .

Nice job. Got to get me one of those miniware irons.

You're a great Teacher.

Very well explained. thank you.

Awesome video mate keep up the good work subscribed

Very useful videos you made great jobs

Great stuff 👍👍😀

Thanks so much for vids love all your work keep it real thanks again . P.S. threw you a thumps up cheers

Spot on, Graham! 👏🏻☕️

Great work!

Thanks for your video, it was very helpful.

You're so practical bro

Iam learning, the explanations are great keep it up

thanks for sharing ... so much learn

best repair channel on youtube

You are explaining each step very well, pls tell us whenever you are using any equipment we need name of each e.g paste,srew driver, capicator name,mosfet name, IC name, for removing the soldering wire paste. Which lense we can use during repairing the circuit ? to see clearly electronics devices on the board. Again thank you very much for explaining everything. You are amazing and doing great work

Great video like always, I hope you make a video. about how use a power supply to find a short to ground the right way...

it worked for me man it's like a charm I don't even have to use any tools I just looked for a broken piece of the electronic part using a magnifier and a portable light torch, found it and removed it and the device starts working again despite the front led indicator stopped working and the wifi switch has no effect anymore but thanks a lot BTW my device is lanovo g570

that was a wonderful video, thank you.
