- I waffled for way too long when recording this video, but I feel like this is all the info that no one told me that I needed to hear when I was learning this stuff. So here we go. If you just want the satisfaction of seeing this laptop come back to life, I'm working on a short-edit with the waffle taken out 👌
SPOLIERS:
Shorted bypass cap on 1.8VSP input (where B+ goes into the regulator)

I've watched a lot of repair videos from all the big guns but its one thing to do a quick video on circuit board repair but when someone goes the extra mile to explain what's really going on in the circuit as well as a lot of what if scenarios and explanations or other components and then on top of that taking the time to edit that video for even more detailed info is nothing short of " masterful" Ive always been a big fan of your channel Graham many thanks
well that was educational on a whole new level. Good stuff!
I am new in repairing noote book ,can i do purchase dell vostro 1720 circuit diagram from u ?
Dells always power cycle 3 to 4 times once you have the bios battery/main battery disconnected. It’s essential retraining it’s self once it’s turned back on to learn what hardware is connected and the speed it runs at.
Perhaps it's because Dell is garbage.
Finally someone explains the entire thing of looking for a shorted component! The process along the detailed explanations are just good. My knowledge about this had too many holes and this was the perfect video. Definitely I'll save this.
These type of videos are the best. 53mins well spent. I hope to one day get into this level of repairing. It is fascinating to be able to look at a dead device, find a way to revive it using your own mind and then see with your own eyes it come back to life because of your work. There's no better feeling I think. I get great satisfaction from finding simple faults and replacing parts. Doing it on a electrical level must be an even greater feeling.
It looks overwhelming every time I watch these videos. I'm always like, "lol, how am I going to be able to do all this stuff? How do I get there?" and yet despite this, I still have the desire to try and understand the basics. I want to get there.
All I can do currently is find faults up to the motherboard. If there's a board/electrical fault, I have no choice but to give up because that's where my knowledge/skills end. That does get frustrating.
The LFC series is great and why I primarily subscribed. The LFC series is at its best when it's videos like this: both simple and complex electrical faults that are explained clearly for the layman. I always look forward to these uploads.
I am also novice/hobbyist but I don't think it's that hard troubleshooting simple power rail faults, especially with wealth of detailed instructions from AdamantIT and other professionals who post videos on youtube. Don't need much equipment either. Just multi-meter with fine tips, a microscope/magnifying glass of some kind, soldering iron and a cheap hot air station from ebay. Of course broken electronics can get much hairier with weird intermittent issues which really takes skill and resource far beyond what's available to a layman.
Graham, Thank you for really taking the time to go through the rails - very much appreciated, also liked the screen charts showing the route of the checks
Same as ^ been watching lots on this type of content and can hand on heart say I learnt something new in this video.
These diagrams were an experiment, they're pretty rough in these videos, but I think I'll be trying it again in the future, either hand-drawn Big Clive Style or just _better graphics_.
@@Adamant_IT hand drawn, aka Dave Cad ? :)
@Adamant IT I agree with @Ed D. Boss about the diagrams being an improvement on already excellent content. I like particularly how you overlaid them as you addressed the real board because it helped me connect the concept and schematic to the real life board. Please do continue to include and develop your idea of using diagrams in your content. Cheers!
So many RUclips laptop repairers just fix the board and show a quick diagnostic with little explanation. They’re almost just showing off but I genuinely feel you are trying to teach people how to do this. In a world where we just throw away so much stuff this is brilliant. People need to learn how to get things working again rather than just replacing them.
One of the best videos you 've ever made. Excellent troubleshooting and the way you approach the problem. The video was so descriptive, explanatory, fully educational and you covered almost all the theory of laptop's circuitry repairing. Well done mate!!
Its a sheer delight to watch you present your repairs. You are a wonderful person and your sense of humor is proof of it. Lol...Wishing you and yours the very best ever. Take care and good luck in all your endeavors. Cheers. Love. 😊 👍
Thanks Graham! That was a lot of good info with a great repair.
Trying the same things lately and with mixed results but this helps a lot with your in-depth educational version of this repair.
Happy I found your channel about a year ago... Since then I bought a soldering Iron (T100), Hot air station, and some other things to help me diagnose problems and of course to help me repair them.
I'm getting better and better with soldering and my success-rate is going up and up with these kind of repairs and to be honest... Thanks to you.
I wish I could be a Patron or help you in some other way but I'm very ill and with these repairs and builds I do I'm trying to stay alive and that works well at the moment.
When... Well more if... Things get better here I'll be contributing to your channel when I can.
Again thanks!
Wow.. just wow... you really are one SUPER HUMBLE TEACHER. unlike other big names in this field, you have the heart to share your knowledge and explain it well so others may learn. you really care for your viewers not just to earn from them/us. This 1hr video is worth watching. You Adamant IT and sorin from Electronics repair school are really the best. Thank you.
I really enjoy such longer Videos and your explanations along the way! Always very interesting!
OK, I'm just a very amateur repair "enthusiast" type of guy. I don't have any financial incentive to learn this stuff but it's incredibly interesting to learn and maybe, if I'm lucky, one day I'll be able to use some of this info to do something. Or, maybe that would be unlucky because I'd have a non-working lappy on my hands. Anyway, I'd like to take a moment to recognize how much effort has gone in to this video and say thanks. This isn't the most glamorous channel on RUclips but the info is priceless. Thank you!
I wish you good luck in your endeavors. The best. 😊 👍
Completely agree with your comment(s). I am extremely unlikely to even attempt some of the repairs that Graham routinely does yet I still find it fascinating to watch and to listen to his explanations of why he uses particular tools and techniques. One of my 'goto' RUclips channels.
Thanks for the great video! One of your best produced yet.
This video elegantly demonstrated the basic skillset required in general laptop repair and showed the process in a stepwise and logical manner. From visual inspection, continuity/ohm testing, voltage injection, FLIR imaging to the repair itself. You covered a broad range of topics that to a complete beginner will benefit watching your Basics playlist.
Great job! Liked and added to my Favorites.
PS
Congratulations on graduating from the Touchy Feely Method! Hoping to own a thermal cam someday.
Really love these hardware repair videos !! You're extremely clear in explanations, and there's always a lot to learn :)
I started fixing laptops recently (well, at least trying it for now - to see if i can actually do it) being quite a bit influenced by Adamant IT and the other guys who do this on youtube.
i found that Graham explains all the steps quite well, and in a way that someone without much experience can understand.
The last laptop i fixed had a short on the +3V and +5V rails due to a shorted capacitor.
Finding this fault by yourself with the help of measuring and studying the schematics was incredibly satisfying.
It took quite some time, but i think the experience i gained from it is very valuable.
Thank you for your great videos.👍😊
Hi Graham. Had some bad pots in my bass amp, and watching some of your repairs gave me the confidence to change them myself. Thanks man, you saved me some $ on a DIY fix.
im glad i found your channel. im just getting into repair and trying to learn as much as possible, your channel has been fantastic. Keep up the good work.
this is one of those vids that is .. GREAT!
one point to mention is the limiting to 3 amps reduces the chances of burning the short out and then feeding the other components.
This makes sense. Plus also, when a component goes nuclear it has a habit of welding itself onto the board, which increases the chance of damage when removing it.
I highly appreciate the presentation. It is very informative, entertaining, educational. Worth the 1HR time watching.
THANK YOU!
Please it wasn't waffling! this is the first video which actually made real sense, your other LFC videos are very good too but this is the best one (or one of the best), i've created a playlist for LFC - Dead Laptops which i just watch again and again till everything makes sense, thanks again and keep up the good work
Great channel! You really know how to pass knowledge to people who want to learn! I am really gonna enjoy all the other videos on this channel! Cheers !
Good God man! The amount of useful information packed into this video was amazing! Great job!
That was rad. Loved going down the rabbit hole with you. That was a nail biter at the end! What a cool video.
Wow, this is probably your best video. Took me more than 2 hours of taking notes and paying attention to detail.
It was great. I'm watching all your a repair basics and you have the best explanations you could ask for.
Plus you are very entertaining and make nice funny jokes 😂
I can't thank you enough for all this work, it's helping me a lot finally finding a way through all of these, as I was pretty lost.
I don't think you 'waffle' at all, you teach, you may think you 'waffle' but it's mostly content we need to hear so keep on truckin' man, you're simply great to watch, your presentations are tops, many thanks for all.
I know this is an older vid, but I just caught up with your stuff and you're the best teacher of this subject, on RUclips, I've found thus far. It's one thing to show, but leagues more to explain in a way regular folks can understand. I'm a retired teacher. Thank you!
That FLIR camera really helped. No wonder everyone was bugging you about getting one.
i got old CAT 60 phone it has termal camera and got it for realy cheap :)
top notch video ! great explaining, great practical insight. outstanding.
53min Let's Fix Computers video.. Oh, yes! Let me get the popcorn!
This has been the absolute best electronic training video I have ever watched and I went through military electronic training years ago. Well done Graham!
Super super super educational video. The drawings on top, to recap the situation, are very helpful. This video is one notch up with the quality!
Excellent. As you said you may not be the top repair guy out there but you have them all beat when it comes to taking your time and explaining things in plain UK English.
That was one of your best videos. 👍
My new favourite channel on RUclips. I've learnt so much. Huge thanks
great video to watch! so nice of you to go through with details and explanations and all. please continue doing more videos like this!
Great video, very much appreciated. The detailed explaining really helped me get a better understanding of the inner workings. Thank you.
Wow! That was a great tutorial! Thank you!
I really liked that you explained the voltage injection part in a detailed way!
Cheers Graham ... Good Vid with all needed explanations of what does what ... Top Job Appreciated
I watch all over the world people fixing electronic but you my friend I take my hat off and why you explain so much better than others keep up the good work tu a million
I bought this same laptop several years ago and gave it to my cousin. I recently did a repast on it and it was a bit of a challenge. It does have a long power cycle and it shuts down a few times when you do a teardown. The newer Gaming laptops from Dell don't have this design anymore and are a little easier to open. Great video, will save it for future reference.
Great explanation of how a capacitor and resistance works. Haven't heard this yet on any other channel. Excellent work!
Love your videos and the precision with which you explain your thought process. Thank you.
I am in awe of your knowledge and capability to fix this computer. Truly excellent, many thanks for the video.
What an incredible video! Well done mate and thank you for sharing your knowledge
Thank you for this well explained video ! You have a gift of explain something in a understandable way.
I can not put in a short line how much I learned from this video.. Well Done my friend Well Done !! BRAVO !!!
As I am watching more and more of your videos, I have to say: You are a really smart and passionate guy. I am sure, with your skill-set, you could easily "go bigger", whatever that might mean. However, I am very glad to see, that you seem to be able to make a living in your nice country-side shop. Maybe, sometime in the future, I might start a shop like that myself. However, if I ever end up in that part of England, I might stop by for a visit. Keep up the good work - really enjoyable content!
Really great video, i normally watch your stuff as catharsis since we do basically the same job. But i learned loads from this that i didnt fully understand, great job!
Great detailed video, please keep doing videos like this as the extra detail and explanations are what makes my old brain cells learn. Thank you for taking the time to go the extra mile 👍
I love your explanation of short circuits.
The best videos on laptop repair i've Seen on RUclips sofar.
Thank you so much for taking the time to make such a detailed video ! I've never done anything like it and all the step by step explanation resulted in me fixing my laptop 😁
Great through diagnostic/repair video, nice job Graham!
This sort of videos are the reason a follow you, i learn so much every time. Thank you for splendid explanations as always. Cheers
i'm liking this type of videos , veeeeery informative for begginers ♥ thank you
You are very good at your profession and at explaining complex problems. Thank you.
Between yourself and Lewis rossman I've learnt so much to the point I've bought a couple of cheap broken ps4 controllers I'm hoping to try to fix them
Never apologise for waffling the more you waffle the more you teach thank you for inspiring me to learn to fix things and also for the confidence to work on my pc
Well,this was something.You made quality videos all the time,but this was just awsome!Very nice and thorough explanation and portable Flir is better than bare hands.
Great video repair , thanks for taking the time to explain everything to the very detail. Liked the testing procedure near the vrms!!!
Awweeeeesome fix! Loved the diagrams and explanation of your process.
Definitely better than the short version. LOVE IT
the rail diagrams were a really nice touch especially because im a electrical engineering student its cool to see
Great video and really professional overlay of circuits good job graham
Just want to let you know that - this coming from someone inexperienced but not wholly ignorant of anything electronics - the detail is indeed very much appreciated. This is great for what I think is going to be most people - you have an interest and a need, and probably have access to a multimeter and iron (or can pick something up on Ebay for a few bucks), but aren't sure what you're doing and lack confidence. A lot of other content glosses over things or treats it like an engineering class with little relevance to what's going on in the machine, and loses context. This video is easy to follow, the video quality is clear (also uncommon :( ) and the explanations are complete and to the point. Actually I don't think I've seen anything quite so elegant in terms of walking through the diagnostic process, at least as someone who isn't already an expert. Easy and enjoyable just to watch, really.
Now I've still got two dead Dell laptops and this is encouraging me to try to fix them. So I'll pass all the blame on to you for the results :P
Best laptop repair video seen
Explanation is awesome
This is great content, one of the bests I've seen. Thank you!
Worst laptops I've ever had to pull apart are the Earlier Panasonic Toughbook series, just billions of plastic bits, seals and screws and the very early Toshiba A - series laptops from the '90s which had multi-layers of boards interconnected and had to go back in the right order with the right screws, nightmare. Great result and use of the Flir camera when applying low voltage, current limited injection. Appreciated the explanation of the way the power bus is connected and how the current flows through in that particular situation where the CPU and GPU are not shorted. What's in the VRM chips and why checking for a short there is important when trying to prevent damage to the CPU and GPU. Great video, loved it.
Graham you are literally a lifesaver!! My Dell laptop suddenly stopped charging and Dell quoted me almost $300 to fix! I followed your methodology from this video (continuity checks/voltage injection) and found a faulty shorted MLCC with an IR camera. A hot air gun and one capacitor replacement later, the laptop was charging again. Thank you so much for this video!!
Amazing guy.
Clear enjoyable and informative.
Lovely show and good channel
This is the best diagnostic video ever!
Great job. Thanks.
Great job Graham. And what a great thermal camera! Regards, Nico.
Really educational video. The IR camera looks a great purchase!
Great video… thanks for showing how to find a short. I learned I’ll never be able to fix a similar problem as I never even used or understand that multimeter stuff 😂. Great Fix . Keep up with videos . Your way smarter than average person when it comes to electronics .
just loved every explanation. thanks alot man. and the DMM is very nice at every scale.
Very helpful and highly appreciated. Thanks for sharing. I had this issue before and I could not repair it but now I have an idea how to get it done.
Extremely good video, one of your best.
Great video bro. You explain things extremely well. 👍
Yet another awesome video! Great info! Thanks :)
Hi there , just i wanted to say thankyou for your tutorial video , thankyou for zoom in to the motherboard and allow us to see with more details , it was very good idea that you put chart or diagram on the screen ,thankyou for your simple & easy explanation. and thankyou again that you explain a lots of things during fix the laptop for beginners . thnx
You are really an amazing teacher. Thank you for your work.
Great video, thank you for taking the time to be thorough.
One of your best yet.
Great video! Keep them coming.
To those who are interested in electricals, Content from you are place of zen. Thank you sir.
Your explanation and procedures are very well put out. I'm always enjoying watching your RUclips videos, the way you explain things is extremely clear even here in the states. I rank you as one of the highest technical explainers on RUclips. Have you ever thought of streaming with your subscribers like video chatting so you can help someone at home that has similar equipment to fix their laptop? I know other RUclips
Content providers used to do that.
Sadly I'm not experienced enough to be able to judge a board that isn't right in front of me.
I've got a project on the back-burner for a "learn to solder" live stream though, to help people pick up an iron and start tinkering with stuff. Bit lower-end than what you have in mind though.
@@Adamant_IT I'm sure it could be possible if the person you're video chatting has an extra camera pointing at the laptop or motherboard. You could guide the person to probe the area of Interest depending on what they get from the meter. just a thought but I do understand where you coming from starting small then working your way up to that level of teaching and helping.
Awesome video, Love how you build up the diagram on screen.
As always entertaining. Thanks from Australia
I love the videos. I am new to your channel. Thank you for educating all of us.
Extremely beautiful and valuable explanation
Thank you so much
I Lee loving your video, this was another great one, I learnt a lot
I love your repair videos!!
Excellent video, learned a few things. Sometimes you can use the suggested or typical use/arrangement circuit or description in the datasheet for values of components. In the SY8286RAC datasheet it states to use at least a 10Uf capacitor in that portion of the circuit. Pin Name:IN, Pin#:2,3,4,5, Pin Description: Input pin, Decouple this pin to GND pin with at least 10uF ceramic cap...A lot of manufacturers and designers use the suggested circuit, if available, with slight or no modification in their own circuit, it's easier... Anyway, good troubleshooting, good video...Thank You...
Thanks! A really good and informative video, I learnt a lot in that one.
Great demonstration 👌
You and Faldstad are my two favourite electronics teachers!
Adamant honesly amazing one again, I realy like your tutorials. You have amazing way of explaining problems. I watch all without skiing any parts. I'm glad you moved to New bigger and better shope, your shope look pro now.
Great video Graham👍🏽
Brilliant work, doctor! Lots of learning potential right here! I dig the fleer cam idea!! That's really cool. Nice clean tear down and test ! I'm subscribing to your co0lumn!! Thanks again!
thanks again for sharing the knowledge and for the informative content.
I love your channel learning some repair skills and nearby improve my english knowledge. Thanks a lot!
