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.

When I started learning board repair, I found out quickly how important schematics were. Some KZfaqrs 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.

@clems6989 7 күн бұрын

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 ?

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

@Adamant_IT 2 ай бұрын

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

@SusanAmberBruce Ай бұрын

Are pre surface mount components better or worse quality than surface mount ones?

@Adamant_IT Ай бұрын

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.

Dang the discoloration of that board around the CPU socket is crazy

@Adamant_IT 2 ай бұрын

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.

@stevewandrie7537 2 ай бұрын

@@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 😂

@KaAl-gc2hp Ай бұрын

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...

@Adamant_IT Ай бұрын

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.

@Adamant_IT 2 ай бұрын

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.

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.

@gamer_5042 Ай бұрын

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.

@Adamant_IT Ай бұрын

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.

@AzuaraRuiz-ot3tt 2 ай бұрын

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.

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.
