case--- asus k54c not power on when press power switch 

but power on without rtc battry


dignosis
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
checked with other cmos battry same issue

checked in switch have 3.3v

when remove cmos laptop power on when put adapter

but when power on if press switch long time laptop goes shutdown but again press no power on

this model have no schematics so it is difficult to find the solution

this board have sio ITE IT8572E SO ITS PIN 122 IS FOR DNBSWON SWITCH

CHECK THIS PIN ALSO 3.3V WHEN PRESS SWITCH ALSO CHECK VOLTAGE DOWN TO ZERO

AFTER LONG SEARCH FOUND 10K OHM RESISTER VALUE DOWN TO 9K OHM

IN PANEL SWITCH HAVE NO ALL 3.3V SHOWN N PICTURE EXCPET POWER SWITCH VOLTAGE

ALL VOLTAGE SHOWN IN SWITCH PANEL PICTURE SHOULD BE THERE BEFORE POWER SWITCH EXCEPT 5V



RESOLUTION

JUST REPALCE THIS RESITOR WITH 10K OHM AS IN PICTURE AND LAPTOP POWER ON WITH SWITCH

AFTER REPLACE  RESISTOR ALL VOLTAGE 3.3 FOUND IN SWITCH PANEL IN IDEAL CONDITION MEANS BEFORE PRESS POWER SWITCH

THIS JOB DONE WITHOUT SCHEMATICS SO THAT CANT MENTION OTHER THING ABOUT THIS RESITORS
