Thanks,
Yes absolutely 0 ohms. All others measure and the number keeps going up.
In diode mode the other inductors measure and give a beep. 462 shows a small measurement that drops to 334 to ground and then doesn't give a beep at all.
Same for 237, 413, 55. Highest on top left one @819 and lowest one at 129 on "326" as per your pic.

Ok, measured all. All seem to be testing OK besides the one I have looked at here in the pic. Measuring 0.

Thanks for your patience so far. I know I am still asking a few things that I could be learning myself. Time just isn't on my side right now.Thanks,

I think so?
Sorry this is very amateur but can the gold plated part of the mobo ground as per below?
When to ground, it measures 0.

Wow must be honest this is a bit high level for me.
f7000 and 7001 both measure 1,8ohms when multimeter is set to 200 ohms.
Will wait for your reply before removing the components....Leave a comment:

That was with the board completely removed. No power. Should it have had power connected?Leave a comment:

Thanks for reply.
F7000 and F7001 measure 0.09V.
D6902 pins
1 - 0.03V
2 - 0.06V
3 - 0.05V
Just for extra confirmation, I took the laptop to the original owner, who I know very well. He was using it, heard the battery pop, or what he says was the battery, then carried on using it and the battery life obviously wasn't as great, and then got a new laptop and put this one away. I also used his 140W charger with no luck.
Also bouht a new battery because if all else fails I would probably need it in any event. Still no luck...Leave a comment:

Alrighty, finally got around to testing with a good charger. 140W original Apple. No good. Still dead.
My main question is, will the macbook power on if the battery is disconnected? I know Apple devices are very fussy with things.Leave a comment:

Not sure if that was the original charger. The guy has a bunch of them he says. I am going to get another one from him tomorrow or Saturday.
Anyway, I presume PPBUS_G3H is the P7000/1 chip? If it is, then it's measuring 0.03V with multimeter set to 20V. Bit new to all this.
I honestly think it might be the charger, so am going to first get one tomorrow before I dive in head first any further.
Also don't have anything to measure the Type C voltage with right now.Leave a comment:

Macbook Pro A1707 - Dead - Battery 'popped'
Hi Peeps.
Just a quick question please as I am by no means an Apple fundi at all.
Can a 'popped' battery cause the Macbook to be completely dead? Client said the battery definitely popped. It doesn't look swelled or anything but it doesn't switch on at all. No lights, no fans, nothing.
Also, using a 85W original Apple charger. That is working for sure. Does it need more wattage?
Don't want to go buy a battery for no reason.
Client is adamant is worked before the battery popped and I can't see any damage what so ever on the board... -
Thanks,
Yeah I was going to use this as a test board to learn about the various schematics and things but it looks like it either had water damage, or like you said someone shorted it with a dodgy charger or similar. Wouldn't put it past the guy I actually got it from.
Will perhaps scrap it and use another board as a test. I don't have the machines for voltage injection etc.Leave a comment:

Hi,
pin 3 - 0 ohm
pin 13 - 0 ohm
PL4501 - 0 ohm
PL4502 - 2.71 ohm
No power attached.
Pretty sure I did it right. The pins on PU4503 are pretty small but after testing them I kept the ground on the same place and then tried another component and it did measure ... I did it 3 times as well. Measured PL4501 and 4502 quite a few times as well because as you said before, it's unlikely that they are faulty.
I will let you know what exact ohms and test again this evening if I have time. Work just has me flooded right now hence the...Leave a comment:

pin 3 - 0
pin 13 - 0
PL4501 - 0
PL4502 - 2.71...Leave a comment:

OK thanks. Will have a poke around and see what I can figure out.

Alrighty then.
Obviously one or both PL4501 and/or PL4502 are faulty.
Few questions:
* Where does one buy a replacement? AliExpress has a few 2R2s but they have no codes after that. Any will do?
2R2 full code is 2R2 547 E86. 3R3 full code is 3R3 545 R51. Obviously these mean something but google searching gives me few and far between answers. From google I can now ascertain these are inductors for Power.
* Presume one just solders these off and on again?
* Can 1 be faulty and the other not? e.g. Can the 5V feed the 3V one? None of them appear...Leave a comment:

cool
yeah 0 voltage on 4501 and 0,56 on PL4502.
Guessing that's not right....Leave a comment:

Yeah did all that. Some pins just look like they have corrosion on still.
Best pics I can get.

Dead Dell Board
Hi Guys,
Back again with more learning to do. I would like to start fresh and not confuse myself by looking through different posts.
I have a Cedar Intel Board that is dead. 13269-1 - Seen a few dead boards here on here.
So pls bear with me and let me know if what I am doing is half right as a starting point.
[ATTACH=JSON]{"data-align":"none","data-size":"full","title":"Dell 13269-1 Ver 1.jpg","data-attachmentid":3296605}[/ATTACH]
Pin 1 through to Pin 3 measures... -
Holy moly....
So right after posting, I inspected the charger. The middle pin was completely bent to one side. Hence it not going all the way in, hence the issues I have been facing for WEEKS now.
I have verified the charging now, BIOS picks the charger up, CPU is running at full speed, and the bttery is actually going up in %.
Thank you for your help and when I sell this laptop, I am going to make sure to donate to this website because you guys absolutely rock.Leave a comment:
