This is my computer, a Thinkpad x220. I am selling it because I need Xcode for iOS development. My plan is to get Macbook Air and then virtualize the Debian to it.

How can I find the specs about the Thinkpad I am selling? Does it have 3G -support? It has the IMEI -number at the bottom so my friend said that my laptop may have 3G support.

You should probably delete the pictures with your serial number, or blur it out... just fyi. The part number is public information and not sensitive, but the serial number is basically personally identifiable information, as it is unique to THAT laptop unit. – allquixotic Nov 5 '12 at 20:36
@allquixotic I cannot understand why I should blur it, what does it matter? – hhh Nov 5 '12 at 20:47
Your serial number and sometimes your name is all that is needed to perform account or warranty related services by calling Lenovo's tech support line. They don't ask for any more advanced forms of owner identification. If we knew your full name or even your last name, we could probably convince Lenovo to take out an RMA on your unit, or similar. ;P – allquixotic Nov 5 '12 at 20:52
@allquixotic thank you, I contacted Lenovo for assistance. What do you mean "to take out an RMA on your unit"? My friend said that I should not share the IMEI number because telephone-something could kill the unit off-site somehow. If there is any truth here, I could kill many-many machines because I know all names and I have local contact to most of them all the time but I find this very odd policy if it is true. – hhh Nov 5 '12 at 20:57
@allquixotic Any idea how other manufacturers act, perhaps I need to think twice which computer to buy next :) – hhh Nov 5 '12 at 21:48

You need:

  1. The Hardware Maintenance Manual for the X220

  2. The Parts Lookup page

  3. Your serial number and part number (graciously provided by your screenshots)

Doing the hard work for you, you have:

The Ericsson F5521gw WWAN Module Japan S is FRU 04W3767

A quick google on the FRU shows for example this which provides the details on the part. Normally you could find it in the HMM too but this one isn't showing up there.

Do I understand correctly that this computer has 3G when some sim-card inserted? Found this about the 04W3767 here. – hhh Nov 5 '12 at 20:45
Yes, it needs a SIM card and a supported carrier. – allquixotic Nov 5 '12 at 20:47
Found the sim-card -slot, under battery?! Picture here. – hhh Nov 5 '12 at 20:48
