    asus x453sa missing all voltage except 19v and charging pin

    Hi, my friend have this laptop
    Before all voltage missing, im already repair this laptop 3x (i have 3 of this laptop and all of them dead, can't be repaired because dead CPU and other component due unknow chips, why always asus laptop have this issue).

    1st repair it short at 3vsus (dead low side mosfe and short caps)
    2nd repair short at CPU Vcore mosfet (low side)
    3rd repair 12v missing (only 1.2v but it can run bios and hdd not detected because 3vs missing).
    and then after 3x enter BIOS it blank then dead (all mosfet buzzing, 12v still missing)
    after 10x check voltage it dead, RT8249C didn't have any voltage except 19v at AC_BAT_SYS and charging pin
