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.
