This laptop won't power on , when power supply is on it takes 0.001 , button trigger on it becomes after a couple of seconds 0.061 amp..and nothing
No heating (Of COURSE) , no short to GNd at all coils present , 3/5 valw is present , 3/5 vl present.
With the power plane , at state 4 +1.8VALW and +3ALW_PCH must be present but no one due to enable signal is missing .
when button trigger on , 3v dow to zero than 3v , the super io send BTN_OUT#_R to pch but no rsmrst ..0v.
i follow his line , no short .
Try a virgion bios UC702 + UC703 fron here no change
this is the io requirements ..( if i miss some voltage please tell me )
+3VL_EC_R present.
VCC_FSPI present
VCC_LPC_ESPI is present
WRST# is peresent
VCORE 1.8v present
ON/OFF present
BUT no EC_RSMRST#..
All rtc section is OK ( i find some corrision at CC1002 and clean it )
my io programmer didn't support this io..
Can we conclude , since my charger section / power section /rtc section/ bios are good that my issue is the bios inside io or the io himself !!
OR is there a differents others steps to confirm before !
Thank you
