Product: Compaq Presario CQ57-455et Notebook

CQ57-455et shut down in bios test. Not open and capslock led once with an interval of 5 seconds. I tried different ram. I've tried key combinations windows key + B key. I removed the motherboard battery. I am trying bios update with usb but not working. Help me please!
