You start with SUS and SLP_S4 stuff, SLP_S3 comes later. Are you using the correct charger 60W or more?

Ah, hello. I only have a 60Watt charger with a MagSafe to Magsafe2 shape adapter ATM, lost my 85W.

You start with SUS and SLP_S4 stuff, SLP_S3 comes later.

I'll check SUS and SLP_S4

I have a couple of questions if on of you guys would not mind answering.....
I have been going in circles on the schematic, noting what turns on what. S3 is sleep state right? So, what is the S4?
What rail powers the PCH?
