Re: Asus ROG GL551JM doesn't charge after MOSFET failure

Were you successful in replacing the MOSFET and repairing the laptop? My GL551JM recently died and sounds very similar to your issue. Battery light started flashing and battery won't charge. Will discharge to 0 and shut off. Laptop won't power on using the AC adapter with the battery at 0 or with the battery removed. Looked at the motherboard or anything obvious (burnt components, loose connections etc). AC adapter is working (has voltage on volt meter) and tried a new battery.
