Your last few words are MOST IMPORTANT "repetition is the key to learning". PLEASE ignore the naysayers who say NOT AGAIN. BRILLIANTLY explained 👍

Hi, I am following you since 3 months ago. I'm an old and retired IT (I'm 62), and began in 1982 to autoteach informatics and unfortunately I don't have any electronic studies background, but since I look at your videos it makes me easier to understand. Many compliments for your activities, thank you for your posts.

Graham please Ignore the negative comments about "just another capacitor repair" these videos are brilliant for us lot that are still learning board repair.

In the olden days I used to read PC Pro magazines help pages where if you had a problem you wrote in with your issue, you waited up to 1 month for it to go in to print, then people would buy the magazine in WH Smiths and reply if they knew how to fix your issue, then 1 month later the answer would appear! Up to 3 months to get an answer to an issue - thank god the Internet came along! It was from reading these help pages that I learnt all those years ago how to fix issues on PCs. Now the modern day equivalent is watching appropriate videos on KZfaq - like the ones you produce! Thanks 😎

little tip when you want to measure a cap thats similar just move it to one pad either side so its still soldered down but out of circuit and cant sod off into oblivion

I am a DYI dabler for my own stuff. I repaired a HDD that had a damaged logicboard last year with help like your channel helping me jumpp down 1 deeper into the rabbit hole. I had a controller chip transfered to a donorboard because I dont have the tools for this one time solder job on tiny stuff. but it worked. For the rest I've been watching and enjoying "yet another short" because its just satisfying seeing you tear stuff down, talk about it in a calm voice and have the enjoyment of taking the journey to "and it works again" :D. keep up the great work.

I can't thank you enough for this, my dad's friend gave me an Acer laptop that after liquid damage wouldnt give any signs of life, I tried cleaning the mobo but nothing, so I just left it for years, but then I saw this video and I thought I could try the same thing, turns out one tiny cap on the cpu power rail had a short which prevented the whole laptop from giving any signs of life, I removed the cap without replacing it cuz I don't have any spares, there were multiple ones in parallel so just removed it and boom it started working.

Thanks for your videos Graham, I have no intention of trying these repairs. It is too late in life for me now but I enjoy watching your diagnosis routines. Thanks Chris.

For small SMD'd like these caps, get a pair of "Hot Tweezers" as per those from Northridge Fix. It'll all be "right first time". No blowing them into the carpet and no joining the contacts as you put them onto the board.

Fantastically educational. I love it.

15:36-this is where a flexible phone holder would come in handy (so you can continue your FLIR/thermal checkup while power injecting)... Dell, IMO has always been the best laptop CO out there, for making it easier on those who fix these things up.

Another video well done. I'm the type of board repair student you're aiming for. I'm learning a lot about diagnostics from you, and I appreciate you covering the mundane "shorted capacitor" repairs. You do a great job of explaining your thinking about diagnosing a fault. I find myself stumbling when it comes to voltage injection, on "where do I inject?" Thanks again for what you do, and how you do it.

Great video again Graham learning more starting to Understand shorts👌👌👌👌

Really enjoy your content and knowledge. Thank you for sharing.

I don't see any repetition in your videos. they are variations on a theme. different caps, different laptops, and most importantly, different techniques and approaches. it has been good to learn with you and watch you becoming more skilled confident.

We can place the smd components on a sticky tape. That way they don't accidentally fly away when testing for a short or for their value

great repair again please keep them coming.

I stopped watching and unsubscribed from Northridge repair because he berated (insesantly) a user for a comment. You do very well handeling these people with kindness and information. Thanks for being a good human. Grain of salt goes a long way.

I really appreciate your videos. I have an old Clevo laptop that won't turn on. The fan spins for a few ticks and then shuts off. I've kept it so at some point when I get a bench power supply to inject power and have a thermal camera to see what's lighting up I'll be able to take a stab at fixing it. When that day does come, I'll be going over a bunch of YOUR videos again to gain some confidence!

Congrats on the 150k milestone by the way!

Very good approach sir thank you.

the cap at the top was pleased to see you :)

Amazing video,very much appreciated...Thank you!!!!:)

An easy way to hold little things like that is a blob of blu-tak works wonders bro.

don't listen to the bad youtube commenter, any repair is great

Well, beyond my skills so that's why I like seeing you do it, very interesting 👍👍👍

Had a Zenbook come in the other day, no obvious short when testing, but flashing power led when button pressed. Ended up being a stupid ceramic cap across the cpu fan power shorted. Lucky i spotted it with one last visual inspection - without the microscope even.

Multilayer ceramic caps, the repair engineer's friend..😁😁😁

good job as usual !!!

Repairing board with faults on main power rail is interesting. Great job.

You are a mad lad ! :)

nice video, by the way you can use a double side tape or a ring of conventional tape to avoid flying components while measuring.

8:50 Surprised to see the Vcore rail is not derived directly from B+. Virtually every board I worked on creates Vcore from B+....I may be behind with my knowledge though, as I haven't worked on any new models to know what the latest "trends" in terms of power stage design are...

Hi and thank you so much for your style and your so well explained videos ! Learning a lot. One question : I have an old laptop with no screen that I would like to use only with a seperate HDMI screen. Any way I could tell this PC to stop using the missing screen and switch to the HDMI one instead ?

good work

Searching up the service tag shows it's actually an Inspiron 14 5482 2-in-1. There are 2 Inspiron 5100's in fact, one Kaby lake one and one that's the classic better-value desktop Pentium 4 in a laptop example from 2004. In case you are curious how to find the laptop like that, just punch the service tag or express service tag into dell's support website.

I use blu-tac to hold when I'm testing, it doesn't ping off then :)

It’s open line not over limit, just means their is no connection or contInuity which is what you would expect passing dc through a cap

hey Adam l see these vids as training vid so thank you

thanks for the video do you mind telling me which model of cam with screen you use to inspection and soldering microscope the one with screen do you use in the video ?thnks

I thought this was going to be a video about a crappy P4 laptop from 2003 but I guess they reused the model number. Still it was a good video. I hadn't heard about there being so many power rails; on ones I've looked at it's just been input jack, main rail, and battery. I don't know why they'd put an extra layer between the power source and main B rail. Maybe it's to support laptops with a disconnect mode for the internal battery but I always figured that would just be a function in the BMS.

In medicine we have a couple of sayings. Common things are common. If you hear hoof beats don’t go looking for zebras first.

Usually what voltage are these caps. Excelent videos

9:32 ".....If I'm honest..."? 🤣😂

Haha, I wish I got these short circuit problems more often. I get mostly logic problems, gpu & cpu shorts that are unfixable. This makes repairing fun when you can fix stuff otherwise it becomes tedious and very boring to take stuff apart and not fix it.

SMD test probe, works for me I have other Multimeter that use only two banana conector for test all whit the probe.

the good old volt injection save the day

Have you thought about using a pair of de-soldering / soldering tweezers rather than a reflow station ?

Electronics Repair School's vaping genius concurs with you that showing common problems on different machines is the way to learn. So the moaners would do well to quit criticising and be grateful that there are people like you -- and Jessa Jones on the phone side -- who calmly mend devices and allow us into your workshops. Failed caps on not just cheaper end machines seem to have been rife in recent years and I find HP to be the worst of the 'big three' brands. Recently I had 2 dead caps on one of their very expensive models and noted the low quality of the components.

You need a good heat detection gun. Expensive but worth it. The Uni-T is a less expensive alternative that works well.

Enjoyed the video. Do you watch any of the Louis Rossmann videos?

Every power fault is slightly different. Always something to learn. In the real world power faults are very common. All logic needs power, so even if it's a "signal" fault it's really a voltage at the wrong level so ultimately a power fault.

What type of microscope / camera do you use? Can you put a link? Thank you!

10μf? Looks like 10nf to me. Great video by the way

What is the sense pin used for? Do you practice ESD protection?

hello my mate , i have a question about touchscreen . can we replace a usual lcd with touch screen one ? does it work ? or touch screen needs its own motherboard as well ? if you know what im saying . thank you so much

whoa , sudden change of clothing at 5m25s

Pls the link for voltage injection video

It would be a surprising video where you fix an exotic problem that hasn't actually happened, the critics need to start breaking their laptops in a novel way if they want to see novel repairs.

Mr.Adam ant - Could you touch on maybe what is causing these shorts to happen in the first place, as it seems to me that poor building componets are being used from the factory, I do agree that these capacitors are like fuses and are doing there job - as well - I think on part of the problem is the miniturisation of the circutry has a bit of a roll here where these componets are becoming a bit of a problem, the resion why I say that is the Older units are built a bit more rugged and are maybe a bit more durable- or am I wrong ???

Muy buen trabajo.

The back of the board could be having monkeypox. All those weird white dots.

Hi can you please tell us what microscope camera you use?

Have you done any videos where you replace a dual USB A port stack on a desktop mobo? I'm trying to replace one on an RPi 4, but I can not get the solder out of the holes that are used to secure the ports to the board. I've tried a solder pump and solder braid but those only gets me so far. I've tried hot air, but I can't seem to get the solder to liquify even at high heat (380 C). There's just a bit more deeper in the hole that just won't come out and it's driving me bonkers. And I have used flux for all things I've tried. Any help from anybody would be great. Thx!

Hello nice video. Could you tell me what paste you use for soldering the board's components thanks

Is the hinge on the DC jack side missing a screw, it is Dell getting cheap?

Hello what electric screwdriver were you using

how do you know that all the threee caps you desoldered from the board, have the same value?

Big boss, Good morning. Please Boss my question is: can i used SWITCHING VARIABLE POWER SUPPLY instead of linear for finding Short-circuit? Thank you

Still subscribed. Thanks for the content. Keep up the good work. בס״ד

hot tweezer's would be handy , you can buy them on ebay for 100 dollars lol

How do we know the size of capacitor without schematic?

Graham excuse my ignorance but what do you think caused this to happen in the forst place, didn't see any liquid damage so what do you think?

have to figure out my Dell Ultra book, runs fine off the power brick but doesn't charge the battery. Will charge the battery if it is put in the docking station using the connector on the bottom.

where should i go hunting for broken laptops to fix? Ebay obviously, but is there anywhere else I should look? I bought all my soldering equipment and did as much studying as I could (mostly in thanks to you). Now i'm ready to do some real repairs.

Hi Graham! I am a PC technic and thanks to your videos i am now starting bord repair i just installed my new station with soldering iron and hot air following your tips Can i ask you the best (in your opinion) temperature for the soldering iron with a 60/40 wire? Btw great video as always!

can you say what is your microscope ? And link to buy. by the way what is you model of the Fir camera and link, to bought. thanks for sharing your knowlage... greatings from Portugal ... ;)

Graham I notice most of your repairs are on Laptops it got me thinking, OK if someone spilled a drink then fiar enough that caused the fault but lots of other faults do occure. So how many pppl buy a laptop and have it sat on their desk plugged in all day and it never moves? So does this shorten the live of a laptop compared to a desktop? I know a laptop looks nicer sat thet than having wires leading everywhere and it taakes up a lot less space but now there are lots of smaller desktops you can get for general office type work. Also does gaming on a laptop ware them out shorter than if it was played on a desktop, so what are you thoughts, have I got a point or am I wrong?

Where did you buy your meter probes. I like them

Sir how can I get thermo came tust like you and his price pls?

Muito bom !

Is a fix like this considered a cheaper fix?

What's the name of your podcast?

🤗🤗🤗

How do i confirm that the capacitors around the CPU you are not shorted without removing the CPU and the capacitors themselves from the board.

Not boring for me

Please keep showing short-circuits, and the other content you've been showing

megadeath cap... did i hear wrong👀

where is the twitch link????

As you note, failed capacitors are very common. Why do you think that is? Is it poor design/specification overloading the capacitors or just poor quality capacitors?

👍👍😎✌️🤟

The Answer is B)

The boot screen at 29:00 shows a date of April 20, which indicates that the CMOS battery (which runs the system date & time of day clock) may need replacing.

Remind me not to buy a Dell !...always had Acer and have never had any trouble with any of mine ! i am a computer technician,but none the less none have ever had any trouble.

dell shortatron

nump

"That is a screw hole" Would not be much of a computer geek if we did not find humor in that.

is closelier even a word shouldn't it be closer LOL

I have an HP labtop charges, but if you turn it on it stops charging battery runs down have to shut down and wait till it charges for operation

Only thing I didn't learn on this video how to take the motherboard out of the laptop and install it back you skipped edited that part out I like the live real time videos why can't you just upload the whole thing and not edit it??
