Thermal camera is always the best and quickest way to identify and finding faults in a computer board

(8:58 - 9:08)"We need to confirm that they are not shorted through the GPU because if so we can give up now". Save that sentence. Another way of saying it, I'm a fan of dell too but I don't want to fight for pyrrhic victories. Excellent work. A sincere congratulations. Thanks for your time and sharing. All the best.

the microscope is a gamechanger not only for inspection but for content use

I'm going to mention orange juice. As it can help cultivate verbosity. Every time I've looked at this video I've forgotten what "spirit fingers" means in this case. In front of fact my current rewatch started because I couldn't remember what it meant and clicked on it so I could find out. Also I was looking for something to listen to while I was performing tasks. Gratitude to our host for your efforts to fabricate this video for our edification and entertainment, and for deciding and embarking upon the course of presenting it to the largest audience possible with the lowest barrier to entry that is practicable. Superlative exhalation of a not sacrilegious nature to Muerto for providing a tool for illuminating and magnifying the smaller details of the world and having it safely rendered unto the gracious host of this show out of an abundance of human spirit.

That microscope has a marvelous picture quality! Great stuff!

I really love the upgrades in your troubleshooting techniques! Not only do I benefit from the technical knowledge you always explain, now I can see the components up close! I really appreciate this! More power to you!

For batteries or capacitors of equal value: when you combine (batteries or capacitors) in parallel the capacity's add together. when you combine (batteries) in series the capacity stays the same and voltages add when you combine (capacitors) in series the capacity halves and voltages add If your items are not equal then you will need a calculator and the magic formula.

I used to use the touchy feely method, and also cold spray. I saved up my money and bought a UNI-T UTi260B and I've been enormously happy with it. Enjoy all your videos.

Thanks for the shoutout. You're welcome good sir!

(Graham showing his burnt hands) "Do you wanna know how I got these scars?"

Woah, that microscope!

Love your channel. Thank you for all your work.

great repair! have a great rest of the week

Thank you for another awesome tutorial. Always learning from the content you upload. Keep up the good work.

wow the microscope image is very good!! I love watching electronics this close!

Another absolutely brilluant repair adam,well done i really enjoyed it,thankyou.

Gotta love the spirit fingers and great job! 🙏🥳✌️

You are really a competent professional and explain step by step for us who follow you. The best at analyzing technical details. Especially when I saw you even measuring the resistive continuity on the volt input wires to detect short circuits, I said you are the BEST.!!Really congrats my friend

Great fix Graham. Have a great weekend. Dutch regards, Nico.

Thanks. You have great soldering skills.

Top video as always!

Another great repair. Thanks.

thanks for sharing your knowledge.

Awesome repair. These Dell shorts keep you in business.🤓

Another great video cheers

that was pretty awesome thank you for the video

Nicely done thank you

You never cease to amaze me.

Nice job man.

Great video thanks 🙏

The microscope looks great,,quality image from it..i like it

Absolute crazy when is come to disassemble some of the Dell business edition laptops.

Great job thanks

Let's see what we have to watch today 😁👍 Damn capacitor 🤣😂

Great video PC doctor.

You might also get either a no-contract phone or a used one. It don't need to be able to call as long as they can update from wifi.

What an utter pain to take apart. Reminds me I wanted to send you that dead Thinkpad.

You make it look so easy. "I drink cider and I know things"

Under the microscope, the tip of the flux nozzle reminds me of the Vaseline jar in kill bill.

Thinkpads are riding on the good rep from the IBM and very early Lenovo days when they were great to work on. Nowadays they're just slightly sturdier bog standard laptops. Without a riveted in keyboard.

Main reason why I prefer dedicated thermal cameras, they just work and don't have random software issues or stop working on future phones. Also easy to replace the battery if you want to have it last practically forever (I assume there's also AA models out there which might be ideal for the usual few minutes of usage every now and then)

Definitely get the Nothing phone! Very neat looking device, and almost stock android!

I prefer the touchy feely methid.

Hi Graham - how do you find working under a USB microscope? I did have a Andonstar ADSM302 but ended up selling it and getting a binocular microscope as I just couldn't solder without depth perception, But then some guys swear by them, maybe it is just me?

Am a big fan

nice work! great video as always. hope you unwind and listen to "the war on drugs" album 😅

ive got a Latitude E7250, on the power inlet what is the plus, the centre pin or the outside? and what size is the connector?

Hello, I have one question please.If I take out from a spare motherboard a MLCC capacitor which I mesure with my meter for capacity, how cand I know the maximum working voltage of that capacitor, if the maximum voltage for that capacitor is for example 3.3V, or 19V, or all the MLCC capacitors have working voltge around 50-100V? Thank you!

That is why there is KZfaq, you search for the model plus teardown or disassembly and you will find somone tearing it apart. You lose some time, but at least you won't damage anything. Also, if you do not replace the capacitor you may be ending stressing the other one, and causing it fail prematurely.

The common cap value is 22 uF, not 20, which is exactly what you measured. You may have had one of those (226)

Can you provide a link on the scope setup?

Another nice video from you, love them all and how you made some basic repairs without you need to buy expensive tools. How do you get the Power Supply values on the screen?

where you buy the mircope ?? and what brand is it ?

@31:42 I've had to work on a Lenovo that tried to spin the fan at boot. It couldn't, so it turned itself off immediately! For the record, that's the wrong thing to do for a laptop. A warning is expected but this was crazy. I only had a few hours to work on it and I had to make a backup of the data so my fix was to soak the fan in WD-40 until it worked long enough to get a copy.

hola tendrias el esquematico de la mother ZBU11 LA A963P Dell Latitude E7450 muchas gracias!!

5:20 I think Lenovo did a 5G laptop with SIM card. Back in the days I had ThinkPad with WWAN, didn't use it but the technology was there. Now is more likely people to use cellular on their laptops, better speeds and 5G getting mainstream.

Great repair again... Hopefully you will have your new phone for your next repair. Makes it so much easier... I've got one question... Is there any indication on how such a capacitor can blow? I've seen you replace quite a lot of them but never heard a cause of the dead cap. Maybe there is no answer and it can be a lot of things that can cause it on different places on the board but still... Maybe you have an educated guess of how these things can blow. Thanks for all your explaining in your vids. I've learnt a lot since my subscription to your channel.

My dell latitude e6540 charges intermittently please any suggestions I have been to every related forum I can find and no luck

I use a wwan card in my thinkpad, for multiple reasons I prefer this over using my phone as a hotspot; 1) I usually only carry a work phone and not a personal phone with a low(er) datacap, no need to take an extra phone since the sim is in the laptop. 2) antennas are way better. When I use my laptop with LTE it’s usually traveling by train or in lower coverage rural areas; eg places where you don’t have WiFi. My laptop will have 3 bars of 4G where my phone is on 2 bars of 3G. 3) phone battery drain. It uses a lot of battery to use a hotspot and it usually drains my battery quite quickly. Having only my laptop battery drain when I use it and spare my phone battery is super useful.

Know any good glues for sticking back together laptop hinges where the brass insert has come out of the broken plastic?

dell thinkpad? isnt it the ibm or lenovo thinkpad?

What is the model of your microscope

I have a Dell Latitude 7480 as my single boot Windows machine, so this video is very useful to me. My Dell is massively underused as I either use my Linux machines or my iMac. When I do use Windows it’s mainly with my oscilloscope, so I use my old dual boot as I'm an idiot who could easily blow it up. In the 90s we used to talk about 'dry cell' for computers that aren’t used, is it a real thing?

Do a video where you fix the thermal camera by using the finger method to find the bad capacitor we all know it is!!

where did you get your multimeter probes from ? are they the original anengs or just bought them seper. ? they are long and needly , so good for smd work

Please, what is the capacity and voltage of the capacitor?

Hi there, I find your videos immensely interesting! Please don’t crucify a noob; i have technical skills to take things apart and put them back together, however have no electrical skills. I recently got a bunch of about 10 Macbooks that a friend if mine was throwing out. Is the learning curve massive? Is there a course I can take to understand and troubleshoot this? Obviously not one of them is properly working. Again, sorry if it is a silly question. You could always do remote surgery and talk me through it, haha! You’ll probably get a funny video out of it. Hope you could respond and thank you again your videos are excellent!!

Thanks for sharing. Is this board gonna work only by removing the bad caps? I don't have this kind of caps, or a donor board. Thank you

Given the current quality of chinese knockoff batteries these days, my first step would be to pull the battery then plug it back in and see if the machine powers up. it has saved me time on more than a few occasions.

This was amazing to watch! If you don't mind me asking, how did you get into this sort of repair, and do you (Or anyone else who feels like chipping in!) know of any resources that'd help a board repair newbie like myself get started? Recognising components, identifying which parts of the motherboard are responsible for what, and knowing where and what to test for all seems a bit like dark magic at the moment --- but I'm looking to move past the "huh, the PCB here is made of PCB" level of understanding, just haven't got the foggiest idea on where to begin!

I have a really hard time trying to fix old laptops. I can manage to open them up and get to the motherboard, but those damn flat cables e tiny flat cable connectors keep breaking on the tip of my fingers. I have convinced myself it's because they are almost (or over) a decade old, but something tells me i might be wrong.

Don't forgrt to replace the black insulation tape on the camera, one of the things you don't like, I ordered the cam covers after you pointed it out.

I use a Infrared thermometer

If your battery is going bad your phone maybe having trouble powering external devices. Nice work.

My wife bought a Motorola One 5g Ace directly from Motorola for $200 USD that she is very happy with. Hers is the silver one. Not sure it's available there, but worth a look.

I watching on D630 vintage he he 😁

Cool..

Could pick up any cheapo android that works with the thermal cam just leave them together as a set.

At 6:51 Dell Thinkpads? I think you mean Lenovo/IBM Thinkpads :)

I'm watching this on MY E7450.

The microscope is vibrant and clear👍✌lose the thermal cam gain a microscope, there's never an easy win.

I am looking to get a digital microscope for laptop repair. What is the model number of your Andonstar? The quality seems to be superb. Do you have external lighting for that, the image appears to be very well and evenly lit? By the way, great troubleshooting. I wonder how many laptops are thrown out here in the UK because of a failed capacitor that costs a penny.

It might have pushed over that small com.. Over too much on the right of the ones you put on

Is the laptop yours or anyone gave it to you?

i would think u have some android tablet laying around that could run the FlirOne. but using the forefingers works for the non flir people!

Almost like they don't want you to repair them.

Nice job finding the short, the old fashioned way ;) Just an idea, but maybe the phone can't power the thermal cam properly. I wonder if you disconnected the power from the phone side and powered it from another source would it be more stable. I'm guessing the phones cheap connectors are tarnished/corroded and the phone can't over compensate and deliver the power the cam needs.

Like ur beard

Thinkpad line is a piece of cake to tear down and repair… and they are definitely built with industrial use in mind… Consumer lines by anyone,,, are a piece of cak-shiat .. hah.. Dell and HP business models are not as easy as Lenovo.. meh- “Bahls” Idiocy is a documentary delivered by our future gen trying to warn us…

this is why i dont like working with a laptop..everything need to open in order to get to the inside

EWWW tape over the webcam it's your fault i hate that now and i have packs and pack of webcam cover sliders :D

Can we post you a laptop to fix? 😍

How much do you charge for a repair like this? Unless it's free, who would pay for a repair like this on a laptop worth £100?

and those hotspots arent very good

Nice use of the most basic tools. (Hands and alchohol always work together well. Make up your own jokes here.)

Sorry but you took that apart wrong and damaged the keyboard. Dell thinkpad that's funny. You seem over worked.
