Hi everyone! I own an asus g74sx (2011-10), yersterday I noticed that my laptop is plugged in, with battery connected, but still draining.. When i took out the battery, the laptop has turned off and can't start it without battery. I checked with another charger, but still nothing. It's not the battery or the power adapter either. I disassambled it, cleaned the motherboard, checked if the ac jack is broken or burned, but didnt found anything... I took out ram memories, plugged to other slots, still nothing... When I take out the battery, and plug the charger, the battery led blinks orange very fast. I have no idea what to do with this problem. Please help if somebody has any ideas. thanks a lot.
