My Asus won't charge nor turn on

[gsyamamoto143]

My asus laptop won't turn on nor charge. There's no indication the LED lights. I tried resetting by removing the battery, pressing the power to discharge and tried again to turn it on. It went on for just 3 seconds but suddenly turned off and won't turn on again. Tried removing the BIOS battery and still happened again, turned on for 3 seconds then went off. Tried disassembling the motherboard to inspect if there's any shorted circuits but there's none. I need help

Could be a bad charger, could be a bad battery (some devices won't start without a working one).
