Yes, In addition to the standard limited warranty, you may have the option to purchase extended protection for your Surface (not available in all markets).

Warranty will depend on where you purchased it. You can check here:

It seems like the brick is the problem and needs to be repaired.

You should register your console at
http://myservice.xbox.com to get an official date on your warranty. You can also purchase an extended warranty if you would like

retail stores require you to purchase the warranty from them at the point of sale or 30days after the purchase date

manufacturer extended warranties can be purchased anytime within the warranty period in this case the 1st year

warranties can be extended even while on the current warranty as the extended only applies after the first is expired (stacked just like the memberships)
