Warranty has been useless for me... Beware that battery warranty is only 1 year, despite purchasing 3 yr warranty. Customer service waits for warranty to elapse before they return complaint calls. Computer keys failed within 2 months, battery within 4 months, they have not yet replaced item stating that machines are only replaced within the first month. 3 xps dell computers in my family, all three developed problems in the first few months. I do not recommend to buy Dell Laptops.
