I do have several original Magsafe 2 adapters, this one was free at the moment :), thanks for the advice though. I will not use adapters for repairs in the future :)

Yes both orange and green light accordingly with charging. Using an original 85W Magsafe 1 with Magsafe 2 adapter. I have assembled the MacBook again since it seems fine with the battery connected. It's for a family member so I don't think I will put more effort into it if it works fine now :)

Strange progress, I can't find any shorts on Power Rails, but I just realized that it starts when the battery is connected, even with the LIO cable

Thank you, I forgot to mention. I have already checked the physical condition og the 9500 connector and everything looks good, and every pin sits properly. I'll move on to the power rails.

MacBook Air 820-3437, shows no signs of water damage, but the owner thinks he might have spilled something in it for a long time ago. The board looks completely clean. It starts fine without the IO board flex cable, but as soon as i connect the IO flex it won't start anymore. I have tried with...

I do :), Okey, thank you, I'll try the connector when I get back from my summer holiday. R5714 is fine.

Yes water damaged. My initial problem with the board was missing One wire 3,42V, but got that sorted. This board doesn't have any components of the LED drive circuit. I have already tried to replace U5701.

The Caps Lock light on this board doesn't work. Caps lock works but no light. I have tried different keyboards and still the same.

This is going to the donor pile, I replaced the SMC and got 12.56V on PPBUS_G3H for about a minute and one of the battery SDA lines were 8.4V before it disappeared and PPBUS_G3H went down again to 12.26V :(. There must be some serious issues with this board.

Yes I know :) I don't understand why I don't have CPU Vcore anymore, I am considering swapping the SMC, but I thought I should address the CPU Vcore issue first.

Yes, I know. I'm stuck on this one. If I try to start it in SMC bypass its starts but with no CPU PPVCore. I do however get 1.5V on PPDDR_S3_REG when it starts.

No, not entirely, the fan starts (occasionally), but I get 0V on the CPU. I have to figure out why that is.

No but PPBUS is only 12.26V, I'll look into it tomorrow.

Something under U3210 that I didn't se at first

No not totally, I have 1V on L7100

Yes they are, Thats why I removed them. Anyway, I have come a bit further, found the short and have put the components back. I now starts but CPU Vcore is missing so I'll have to figure out why that is.

To answer you question, I do get 3.12 on pin 16, an 0V on pin 17. I now need to figure out why it won't start anymore

Oh, Pin 4 is short to ground. Yes I have 3.3V on Pin 5 and of course 3.3 on 1 and 2 as well. I have tried removing R8185-R8187. I have also removed U3210 and U7870 but the short is still there. As far as I can tell I have removed every component on that rail now so I'm afraid the short is in the...

Okei, sorry, of course. I get nothing on pin 4 on U8180, seems like I have a short

I'm sorry, but should they present even if it doesn't start anymore?
