I've had this laptop for almost 2 years and it has never let me down... Until now. I only use it for school, so since we just got off break, it has been sitting, not having been turned on for about a month. I go to charge it the night before a full day of classes, and I get the blinking white and orange light & a prompt saying "WARNING: The battery cannot be identified. This system will be unable to charge this battery." I've done everything I can think of. What next? Other than buying a new battery.
