Sorry about the lack of multimeter cam. Looks like I forgot to include it in the export - not worth destroying the analytics with a reupload for that though, so it'll be back next time.
That's ok you explained each of the readings, saved us from trying to read the meter and watch what you were measuring.
Board repair😀😀😀....nice work!!!
Can I ask a bit of an off-topic question? Where's the name, "Adamant IT" come from?
Just for a second I thought you were going to finish early... But at least we got a happy ending.
"We maintain a level of professionalism here", oh Lord.
Oh Lord, Graham Lord.
Really ????? lol
Well, at least we know what the chip is doing! :P
When I started learning board repair, I found out quickly how important schematics were. Some RUclipsrs just post easy looking videos of shorted and broken caps and they give a quick explanation leaving a lot out. Also, I do have to say, this channel is the only channel that really has helped me learn board repair. If you want to truly learn board repair, this is the guy to follow.
the face after the comment about no comments at 20:08 is why I watched this
Great video. You had me in stitches on the out take. 😂😂
Ya, that beard does make one chuckle.
A blooper reel... that's a rare treat!
Love your videos man, so informative and very fun to watch, I learn something new with every video, the outtakes are a nice touch, thank you for the upload! :D
It's been great watching you progress over the years with your repairs. 👍
Absolutely love the outtakes, so funny!
cool! Power injection and thermal imaging! That was a joy to watch. Thanks, Graham.
You really are a fantastic teacher, you explain things so well. I always look forward to your uploads. And you do great closeup microscope views of the board components. Big plus.
Really good video man, well done on including the outtakes at the end too 🤣
Hm. That strangely named chip... two different takes about it at that. ;) Oh, and bonus outtakes as well.
I looked in on this repair because I have got one of these computers. Nice to see your fault tracing technique, thank you. 😊. My computer works fine, and I fitted a different HDD and loaded Linux Mint onto that.
great video. thanks
20:10 the chip is not coming 🤣
Always stick around for the post-credit scenes....
Great work
The outtakes last longer than some dudes. What a coincidence considering the name of the chip.
This one gets better and better.
QqCUM chip, 3.3V.
Sorry, I missed it. What was that chip again?
💦
I love your teachings, but I think it would be helpful to have another inset in the video of a shot of your meter readings as you're probing around.
Glad I stayed for the happy ending.
At least you got a good laugh out of it. So it's a win in its own right.
Very nice
they get chips that do that now? damn! lol
great bloopers
Thanks for the video, I'll come again next time.
In cases like these, can you ask for the defective board for parts? Straight face please!! 😅🤣
I always learn things through your videos, electronics mainly and english! your way to speak for even no natives its really nice for learning. Very thanks mate!
love how you call probing stabbing Graham LOL
Me too. It sounds very authentic. It reminds me of the movies about the Roman legions. Lol.
I have this latop (if its an i5 1235u) and was wondering if the RAM is upgradable and now I know it is :)
I mean it had everything down below happy ending the works
If I understood correctly, the short was between layers of the board at that one point right ?
You couldn't fix by cutting a small section of board away or micro-drilling a hole there etc, and re-routing a couple of traces if need be ?
I have to pause and walk away 🤣
Another interesting video, even though the solution was replace the motherboard.
At 5.49 you mentioned "maybe our battery charger or main rain supply depending on what main rail we got"".Please can you clarify "depending on what main rail we got"" because my interpretation is 19 v is the only main rail on laptops. tks
There's two topologies for the main power rail, Hybrid or Narrow VDC. I need to make a video about it some time, but it's on the bucket list. If you want to read up on this, here's a great primer by Piernov: www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/80414-laptop-battery-charging-circuit
why you do not fix the PCH ? You posted a video at Apr/01 how to do it with a milk 😀😀😀😀😄
I watched a video of you installing the aorus z370. Unfortunately you didn’t go step by step. I know you created this video five years ago.. but perhaps you are willing to help me out with a problem im facing?
come fly with me .come fly and fly away lol
Pattern in thermal camera looked like from the back side to me. Did you check the back side?
I did, yea, it was more noticeable on the top-side.
i3 12th gen better than i5 11th gen, surprisingly
I did wonder that, but wasn't going to start looking up benchmarks in the middle of recording. As long as there's 4 physical cores, I'm happy, after that IPC is king as far as I'm concerned. 2c4t CPUs I tend to avoid, because even with good IPC, 2 cores are just easy to overwhelm.
Dang the discoloration of that board around the CPU socket is crazy
Yea based on the writing on the board, I'm wondering if this CPU got reflowed or something like that at some point. Wild speculation, but that hand writing on the board ain't factory.
@@Adamant_IT I was almost thinking the same due to that discoloring and the writing. Only the board knows for sure, and it's dead 😂
Are pre surface mount components better or worse quality than surface mount ones?
Sort of. Through-hole can be more robust because it's less vulnerable to thermal cycles (legs can expand/contract), but for the components that matter like capacitors, through-hole caps aren't exactly reliable either. It's a moot point in modern computer design because you _have_ to use surface mount to get the ESR down. Capacitors with long through-hole legs just aren't fast enough for modern circuits.
Just a thought... how common are this kind of failure's? Do u think it has any tng to do with PCH and CPU being on the same chip? If so how concerned should i be coz i got msi modern 15 laptop with the same design... pch and cpu on the same chip.
I've had it for a yr and its a nice laptop. With worst possible screen hinge designs...
PCH failure is very common, yea. And yes, the PCH doesn't like the amount of heat that the CPU core right next to it is kicking out. However, this is basically how the vast majority of modern mobile CPUs are built (as a CPU/PCH combo chip) so there's not really anything you can do about it. Like, buying a different model of laptop won't solve this because it'll be the same.
Hope you had a box of tissues handy 😂
please select the language for the windows setup kinda OC with it hahaha
Motherboard death by Qqorgasm?
What termo camera are you used?
Infiray P2 Pro
Be Nice if Your Omh Meter was on The Screen..
I think that chip had a stain on it
Professional comment. Nothing about any chip!
you are overcomplicating it , there is close to 0 ohm short on power rail , injecting 0.8v can't damage anything , there ain't a thing on this board that's meant for voltages lower than that.
And then you inject on a sense line that goes into the EC and kill the board.
I am teaching an abundance of caution, but also teaching people how to identify sections and navigate a board is never a waste of time. Blind repair only gets you so far - at some point you need to learn how to figure the board out.
We are professional, we dont talk about a chip on the board. It is not his fault that te laptop is dead.
Done watching, thank you very much for the informative repair video. I have learned significantly more troubleshooting & repair lessons in this tutorial video and to your other repair videos as well compared to my ENTIRE 4 YEARS OF COLLEGE due to the rotten & outdated standards of education here in the Philippines. I hope you will soon have a mini-series for Schematic & Boardview-free Voltage/Power Rail Tracing[12V/18-20V Main Voltage Rail, 5V, 3.3V, CPU/GPU Core Voltage Rail, DRAM Voltage Rail, IGPU Voltage Rail, System Agent/Northbridge Voltage Rail, PCH Voltage Rail, BIOS Voltage Rail, Battery Power Rail], Proper method of testing/checking of potentially faulty MOSFETs & ICs/Controller Chips, CPU/GPU/PCH Reballing and BIOS Bin File Editing.
Resp Sir! Very Nice Tutorials. -- ChinnaRao Paderu Visakhapatnam Dist, Andhrapradesh
Normally, when you observe that each component in a device is not identified with alphanumeric characters using indelible ink (commonly white); That is to say, such a device lacks silkscreen printing on each PCB that makes it up, so for that device you will not find the service manual (schematic diagram) either. The majority of recognized manufacturers whose authentic models meet this requirement will be able to enter (be accepted by Quality Control agencies) the demanding North American market (USA and Canada mainly). Another way to say it: I see the PCB silk-screened so I'm likely to find the service manual. NOT screen printed? well... Greetings.
Qqcum busted all over the pch.😂
what on earth has Q been upto on that chip lol
Cum on it’s the internet they will always be jokes
OK question how much is a quid
About 1 lbs.
Quid = GBP
It's the British equivalent of 'bucks'
Trying to sell an i5 sony laptop on facebook marketplace for 50£(100au$). Nobody wants it. I'm surprised i see so many laptop repair videos still. A dying industry. Bring back Amiga laptop.
Idk man, im kind of desperate. My computer has been dealing with crashes since the day I built it. I cannot for the life of my figure it out. From SFC scans and repairs, to pouring over Event Viewer and removing software, to scouring windbg for hours reading several dumps. Im at a loss. I have no idea what is causing my crashes. I have tried some other boards with no help. Grasping at straws but if there's any suggestions of anything please help me out. I'll try anything before giving the PC a fresh windows install.
Sounds like bad RAM or a bad SSD.
Don't buy HP, kids
