I was just helping our India marketing team with some English text for their support website and came across this really easy to use GIGABYTE motherboard warranty tool: http://ggcs.gigabyte.com/service/CheckWarrantyStatus_IN.aspx.
Simply type in the serial number on the retail package of your motherboard (include the full serial: e.g. SN111900003001), and select the country where you bought it.
After clicking on the ‘Submit’ button it should tell you what motherboard you have, and how much time you have left before the warranty runs out. You can see from the screenie below that they P67A-UD7 that I’m using is under warranty until April 24th, 2014.
Enjoy! Let us know what you think of this tool on our facebook page.
