820-2523 missing PM_SLP_S4_L but will boot from onoff pads

[2informaticos]

Only iCore platform machines boot automatically when charger is connected (without battery present).
This behaviour is not valid for old C2D machines.

Power button, routed through keyboard, failed on these old machines.
Some videos available about recover it, wihtout changing the KB; not always possible.

That's good to know, thanks a lot. I don't usually touch anything C2D but the customer insisted.
