I need the machine type and serial number of my T440s. I can't find it at the bottom of the laptop. Is this normal? I remember that it was clearly visible on my old T420s.
In that case you might appreciate this approach (run from command line):
wmic.exe csproduct list full
It gave me this output on an X200:
Description=Computer System Product IdentifyingNumber=S3R1AL Name=xxxxxx SKUNumber= UUID=-removed- Vendor=LENOVO Version=ThinkPad X200
Found it: Unlike other models, the T440s displays the S/N and machine type in the battery compartment. Thus, to see it, you have to remove the battery.
From the command line:
wmic bios get serialnumber
