how-to-inject-voltage-in-laptop-motherboard
basic idea how to inject using external power supply
example image power supply
1,19v B+line suggestion inject 5v-12v
2,Alw5v line suggestion 2.5v-4v
3,Alw3v line suggestion 1.5v-2.5v
Proper voltage injection for safety
For shorted motherboards with 0 - 2 ohms reading at DCIN current sense resistance 1-2 volts only
For laptop motherboards with (no available schematic diagram) or the voltage limit is unknown, you can safely inject: 1v only
ang gamit natin power supply always check accuracy voltage output, pag mag inject lagi mababa muna ang current sa umpisa then adjust dahan dahan mas ok kung wag sakto ang voltage nya.. lagi mas mababa applicable ito sa mga any type of electronics circuit......
