Dell Inspiron 7559 5 Y/O laptop has broken motherboard lockdown - I contacted Dell and sent laptop in for repair - 4 weeks later I received a call from support stating the part is no longer manufactured and is out of stock. 5 weeks later. I received the laptop back - minus the battery. I realize the battery can become swollen and may not be shipped that way. Horrible customer service experience - I will never buy anything Dell!
