hello my friends
i have a board with strange problem
as dc connected,is us 0.03A

after pressing power button it goes to loop of two phase:
1-power led blinks 12 times ans still use 0.03A
P_+3VALW_EN= 3.16V
+3VLP=3.19V
P_+3VALW_O=3.3V


2- and then power led goes off and it use 0.13A for 10 sec and pu5601 get hot
P_+3VALW_EN= 0V
+3VLP=3.25V
P_+3VALW_O=0V

and repeat

i tried different bioses but no change
loop is same with ac and battery
i couldn't find any short circuit

any idea?

it was cpu
+3V_SPI was 2ohm and after voltage injection cpu got very hot
