I have a certified refurbished T530 and the attached manual says the serial number is the ME #. I don't see any serial numbers on the exterior surface or inside the battery bay. The manual says it's on the bottom of the machine but the only number present begins: NLENT
How do I get the serial number of my unit?
Since the device is refurbished and not out of the box, previous owners may have made changes so the SN on the case might not match the internal data.
So, to check it: - hit win+R, type cmd - copy-past the following string in the window opened, by right click wmic.exe csproduct get vendor,name,identifyingnumber,uuid
The 'identifying number" result is your compuuter's SN.
