Well, old friend, glad to see you here...
Go into BIOS...I don't know what it looks like on X301, but should state something like "unit serial number".
The first seven characters are your model number (like 2373KTU) and the rest is the actual serial (L3878PC9 for instance)
Let us know whether this worked for you.

Alternatively (to George's suggestion), you can look that up in ThinkVantage Toolbox in Windows once you launch it.
Hope this helps.
