|Just had this laptop returned with new motherboard and new battery. Both genuine Sony parts, battery is correct model number. Battery won't accept charge.|
Sony support says the BIOS needs to be flashed to recognize the battery - they will do it for me but I need to send them the laptop. I can't do that, for a number of reasons, so can I flash the BIOS myself?
Machine works perfectly on mains power, the only problem is the battery won't accept a charge. Before it ran down the machine worked perfectly on battery power.
