Hello, I am seeking help in identifying the motherboard for a HP Pavillion notebook ze4547wm Product #DM753A. Machine is dead after winflash BIOS update so no ID programs can be utilized. If after the mobo is identified can a non-OEM motherboard be used? If a non-OEM cant be used should I attempt to de-solder and re-solder a new EEPROM PLCC? We have a 1 machine license for a chemistry program which will cost $300.00 to transfer. Any help would be greatly appreciated!
