I want to know how old my lap top is. I am not using the lap top at this time. It is a Dell M5040 with a serial number of F5PTMRI
Amazon tells me your laptop model hit their shelves on May 18, 2012, so it's probably about 4 years old.
Your laptop was shipped on 14 March 2012. It's warranty expired on 13 July 2013: http://www.dell.com/support/home/uk...
