Hi,

I bought this from "you know where".

The macbook looks like a new macbook. Not a single scratch not even at the bottom of the macbook.
No liquid damage. Seller said it just stopped working one day. I'm sure I was the first person who took
this macbook apart.

Lot of dust in it. No liquid. It wasn't dropped for sure.
It doesn't power on.

Well some measurements:

Has green and orange light. It charged up my test battery. Went from orange to green after an hour.

PPBUS_G3H 12.55V
PP3V3_S5 3.3V

SMC_RESET_L 3.3V
PM_PWRBTN_L 3.3V
PM_RSMRST_L 3.3V
SMC_ONOFF_L 3.3V

Here is the problem : PM_SYSRST_L 0V.
There is no short on PM_SYSRST_L.
This comes from SMC if I'm not mistaken.
Bad SMC?

Thank you.

C1802 was pulling down PCH_SRTCRST_L. I learned something today. Thank you for your help. The board is working.
