i have this laptop from the title that pch was dead, replaced it. Then figured POWER SW. SN1409049DPUR also shorted and it8171fn shorted. replace them...
Now the board when power inserted is showing white power light but nothing is hapenning. I figured that from power SW. SN1409049DPUR i have this reading:
3vsus 3,2vol
3va_dsw 3,2vol
+3va 3,2vol
but +3va_ec only 1,7vol
So i replaced power sw. SN1409049DPUR but same thing..but then i noticed when power brick inserted for a split second i have 3,2 v on +3va_ec but then it drops to 1,7v. So i removed it8225 and without it8225 i have +3vol on +3va_Ec but when i soldered it8225 back again i have 1,7v on +3va_Ec .
So, is it8225 dead? i dont have new one so i have to order couple of them but just wont to make sure that problem is coming from there? any thoughts?
