How to find the serial number of a machine?


There are several ways!


1. Find the label:


2. Read it from BIOS:


Press F1 when you see the Lenovo/ThinkPad logo during start to enter BIOS.


3. Use The ThinkVantage Toolbox:


Start>Control Panel>Lenovo's System Healh and Diagnostics. If it is not installed, get it from here:


4. Get it from the command line:


Open a Command Prompt (filename: CMD.EXE) and issue either of the following commands:     


c:\windows\system32\wbem\wmic.exe bios get serialnumber

c:\windows\system32\wbem\wmic.exe csproduct get identifyingnumber

Lenovo N23 winbook warranty lookup not working, my daughter has it at college and I need to upgrade warranty and time is running out


Hi there, I have a x1 carbon 2nd gen and I was wondering if there was any way to find the Serial Number other than through the BIOs?

Thing is the sticker was removed and since I have a problem and can't start up the computer... I can't access the BIOs...

If anyone has some suggestions Smiley Happy
