Technical Support asus fx505dd

This asus works fine on battery, but shut down on adapter in 5 10 seconds. display comes on when we start the laptop and goes off in 5 to 10 sec. Even after display off all voltages are there. cpu and graphic ic heats fine even in off state. Any idea. On battery even for 2 hrs machine works fine

Voltage the input jack path to ac_bat_sys voltage. Check if the voltage drops? The coil or MOSFET may be damaged along the way. Also check the charger.

i have replaced the charger. All voltages on all coils are same . Cpu and graphic ic heats in off state .

one voltage drop down slowly when you turn on the motherboard with ac adaptor . you must find it .check b+ , always voltage , ldo voltage ,....

cpu voltage, ram voltage , graphic voltage , always voltages are same in both the condition. Even when display goes off , cpu and graphic ic is on.

I uploaded the bios for clear me file. I was given a file. No, same problem. I asked other person. He says there is no clear me region issue in Amd cpu. Now what to do . This board is very expensive.
