Battery indicates X; fan is running full out
MacBook Pro 15" indicates an X at the battery display; also fan is running full out. Unit is plugged in and not recognizing a charge. I'm sure this is a common issue. Tried resetting a few things as per the "online" advise but to no avail. Help. Doogle23
