How to update warranty to reflect actual purchase date? (vs date of manufacture)

I just bought a new old stock Z61M that came with 1-year warranty. It was made in Feb 2007 and the online warranty status check shows the warranty will end in Feb 2008. How do I update the warranty to reflect my actual date of purchase vs the date of manufacture in the system? Thanks!

 

You probably will need to contact Levono about it, and provide a sales receipt. Of course, they might just instead offer you an extended warranty...so good luck.

 

I also have an issue (good one), My T61 just shipped and when I look up the Warranty info it says the warranty is good through 8/17/2010!!

i did not buy an extended warranty...I made a screen shot of the page...Do you think this will "stick"

Here's the detail from warranty "fine print":
