history, = In for no power, a couple of small areas of dirt on board but nothing notable,
Nothing happens in case other than green then solid orange light,
On bench same deal ,
Will get high fan spin in SMC bypass mode but no boot or display,
Using original 60W magsafe
PPBUS_G3H = 8.590

PM_DSW_PWRGD =3.418
PM_BATLOW_L = 3.190
SMC_ADAPTOR_EN =3.389
As PPBUS_G3H = 8.590v and hasnt dropped top 8.23 or 8.16 am I correct in thinking SMC is fine and communicating?
All voltages look good and SMC seems good? any ideas im stuck.
(( PP0V6_SO_DDRVTT = 0V ---- Is it this? a problem with U7400 ??
