(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.
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.
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!
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.
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.
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
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)
Yea I realised that in editing, I figured it was tolerance. However, I didn't have any 226 caps either, else I'd have gone for one of those. Going to buy some though, because this isn't the first time I've stacked 10ufs to replace a 22.
I really really really wanted one - I can't overstate how much the design appeals to me. The only thing that stopped me yesterday was that I'd left my wallet at home, so couldn't bash in my credit card on the Nothing website. Caradog twisted my arm into buying a Pixel 6 refurb on Amazon, which while kinda boring, is a smarter choice. Better specs all around. Last time I bought a mid-range phone it just didn't have the life span I wanted, and I told myself "always buy last year's flagship." So Pixel 6 it is.
@@Adamant_IT I mean, that is in fact the sensible choice, especially with it being a refurb which means less stuff potentially in a land fill. That being said, Pixel 6 is still pretty mid-range, though. Definitely has excellent hand feel. Hopefully it works with the FLIR without issue! Touchy feely method is tried and true but it's better to use the tech to fix the tech for sure.
That is why there is RU-vid, 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.
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?
I've not used a binocular scope before - I'd imagine it's better due to the depth perception. However, if you need a video feed out of the scope, trinocular scopes are mega expensive I believe, so this is a good compromise for cost-vs-features. But yea, if you don't need the video feed then I think binocular would make more sense.
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!!
if you watched the live steam you would know like we do after caradogs 1 hour diversion into trying to work it out :D, it's the Software cocking up the android permissions system is not letting the app specifically talk to the USB hardware even though he says yes on the permissions prompt
Yea it's a bizarre software issue that seems to have gotten worse over time. The Flir I use has its own battery, so not a power issue. Ordered a refurb Pixel 6 today though, so decision made.
@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.
While I'm no fan of HP, and their fans seem to be particularly prone to failure, they do have a good set up. Spool up at power on, then shut off, give a POST error message if fan doesn't spin, allow the user to continue at their own risk...
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.
"Nowadays they're just slightly sturdier bog standard laptops. Without a riveted in keyboard." so they are still substantially better than most laptops today in terms of repairabillity...
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.
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!
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.
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.
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.
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.
It's a software issue. The thermal cam has its own internal battery. The software for it isn't great, which doesn't help, but it does work just fine on another phone. My old Huawei P20 just seems to aggressively block apps from accessing USB devices. I've always needed to fumble around to get it to work, but since the most recent software or system update, I can't get it to work at all.
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!
For board-level repair like this, I watched a lot of Louis Rossman videos from his earlier days. Having a basic understanding of electronics (resistors, capacitors, transistors, etc) is a tremendous advantage though. It's on my bucket list to do a 'practical electronics 101' video that's a super dirty crash course. A lot of electronics basics go heavy on theory, which is important, but also very daunting. To get started with repair, you don't need to know how to calculate how much bulk capacitance a chip needs, you just need to know that the capacitor next to the chip is important for stable power into the chip.
@@Adamant_IT Ahh, good ol' Louis Rossman, I'll have to give some of his videos a rewatch! And if a 'practical electronics 101' ever happens, I think we could only describe that as a pro gamer move ~~~ Thanks for taking a moment to reply!
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?
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?
My Bench PSU has a USB connection, and some very dodgy software that can monitor it for data logging. I screen-record the software, and then green-screen out everything but the numbers during video editing.
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
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.
Yea, internal crack is the failure method... as to why they crack, probably heat-cycling leading to fatigue, combined with laptops getting bashed about as well.
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.
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.
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…
I actually have a video in the works where I do a bit of repair on some hinges, although the footage isn't great. I use two-part epoxy, however there needs to be plenty of plastic surrounding everything or it'll likely break again. It's very rare that I go for a fix, rather than replace the plastics. The other option is the Electronics Repair School method of _fill the whole thing with hot glue_ which works, but I can't bring myself to do it personally.
This is a bulk decoupling cap, given that there are another three next to it doing the same thing, it would almost certainly work without it. However, it's best to replace. Capacitor kits are cheap on ebay and will cover you against most of the stuff you'll come across.
@@Adamant_IT Thank you very much for replying and apologies for my late reply. Indeed I confirm it worked only by removing the faulty capacitors. I have ordered spare capacitors. Thanks again
I'm fully booked with work at the moment, but in the future I'm aiming to overhaul my workflow so I can do mail-in repairs more easily. I'm not very well set up for it at the moment, so they just don't get done fast enough.
@@Adamant_IT appreciate the reply. I just can’t find anyone of your skill level in the U.K.. we don’t have a Louis rossman 😅 you are him far as concerned. Got a MBP A1706 that’s done it’s usual sudden death. And I have no idea who to send it too. I’m from East Midlands but prepared to mail anywhere.
