Dinala po sakin ng Co-Tech as No Power
Mga Ginawa ko:
Voltage Check ako sa 3.3v
At 5v wla ako masukat
Sa 19v Rail nman wla masukat sa input voltage
Kahit good ang 19v adaptor ko

Solusyon:
Fluid teknik sa paghahanap ng short
At kapa mode sa posible abnormal na init sa board

Salamat nman at d ako nabigo Huli si capasitor
sa 19v rail, lagay ako fluid sa capasitor tas input 19v pag linalagyan ng fluid mabilis na ddry capasitor,bunot ko at hinanapan ng kapalit same size capasitor galing sa scrap board
At Sa wakas nag Normal na lahat ng voltage all.
