3. check if console in RCM automatically from cold start.
you were right! it was stuck on AutoRCM. thank you :D
Keep us updated on what you find.
maybe the same applies for your situation? Since M92 and BQ24 caps showed no short, I just confirmed USB was ok and then tried injecting with TegraRCM.
to confirm USB, unplug BATT, plugged in charger, checked BATT leads on board to confirm 4-5v.

Can we make a TinySoldering™️ meme? ;)

Thank fook I`m second poster!

Right... Heres something to get you going... @WadsRUs

EDIT: 24.06.19 Correction of BQ24193 47nF cap
Hello,
I would like to know the resistor value pointed by light blue arrow in the picture (Fig.1).
The board I'm dealing with is really messed up by the last owner at the same resistor (Fig.2).
I guess he was trying to solder the trinket M0
It booted OFW normally, and cannot boot into CFW due to broken SD connector.
After cleaning the pad (Fig.1), the board doesn't boot OFW normally and stuck at the Switch logo.

anyway, now the Vol +/- buttons are not functioning, power button is fine.
I would like to ask about the resistor value, and hoping to repair the vol+ button
Also, is the red line a correct jump in Fig.1? I would like to do the jump since the pad is totally gone already.

RESISTOR is 150 ohm. And yes .jumper path is correct

Just wanted to add my two cents to this, someone might find this helpful.
I have a HAC-CPU-20 board and the resistor values are very different to the ones in this picture.

The picture lists all resistors down by the BQ24193 IC as being 10k ohm 0201.

On closer inspection I've found the following values on a HAC-CPU-20 board that works perfectly fine.

hopefully someone who needs this will find it useful.

That's interesting to see a 0Ohm

Yeah, it read 0.1ohm on my multimeter so I assumed it was a 0Ohm.

I've seen a few of them before on Xbox one S parts, but they're not all that common I dont think.
In the industry I work in, they are usually used for splicing where replacing a wire modification would take too much time and effort than would be allowed. snip the wire, bond a 0ohm resistor to the board, and continue with the modification. This is usually with long lengths of wire, normally enamel coated.

Does anyone have photos of the Mainboards that aren't marked up and haven't been worked on at all? I'm trying to compare the two I have with fresh boards, but most of the photos I can find are too blurry, or have been marked up with drawings. I have both HAC-CPU-10 and a HAC-CPU-20 mainboards and need some comparative photos of both sides for each.

I have a HAC-CPU-20 that hasnt had any work, are you looking for a particular side/section of the board?

I'd like both sides, with the highest definition possible, so I can zoom in on different parts without any or least amount of pixelization. But whatever photos you have would be great, so I could make a collage or something if I need to.

anyone know the value of the black capacitor near the power button connector?

pic1 is normal switch and pic2 is switch lite left board.

Molex 503480-0400 same as the backlight connector thanks to @WadsRUs not tested.



Or
Do you know if that connector can ALSO be used on the fan connector below it? They appear to be the same size and the mounting appears to be the same but wanted to ask before I go trying to use an improper replacement since I do not have a donor board.

yes, backlight CNT and power CNT are interchangeable.

Fan connector is jst 04FHS-RSM1-GAN-TB(LF) i already posted in his thread and tested.(only diference is the retention tab is black not grey)

https://www.ebay.co.uk/itm/10PCS-X-04FHS-RSM1-GAN-TB-LF-0-5mm-pitch-4Pin-JST-Connector-/332231390814
or
https://www.aliexpress.com/item/100...c2-1&pdp_ext_f={"sku_id":"12000022451939961"}


or same color more expensive

https://www.aliexpress.com/item/100...fd-0&pdp_ext_f={"sku_id":"12000024701006571"}

I don't think you can use the backlight/volume/power connector for fan.

So, I see continuity but again no fan spin. Do you know if these things have fan spin at power on / measurable voltage that I could probe for just to confirm 5v is good? As right now I don't think I see any when the switch is powered on.

    http://harmful.cat-v.org/software/OO_programming/ <- OOP allows a generic build to scale approach to solve problems. And compatibility. In my experience an API/Shared Libraries by being encapsulated, is less likely to get optimized/destroyed by the compiler, specifically in embedded platforms.

    No doubt it will be slower, but if you can and have the resources to hand-optimize away the code

    Also allows to separate pieces in components: Init, update, destroy, which enables the whole program to be inheritable. If you're creating a first person shooter, and want to add multiplayer, you will have to use OOP regardless.
