No Support

First - please don't confuse a hardware warranty with technical support, they are two distinctly different things - if the device doesn't power up during the warranty period (which is probably one year since it's a consumer product, the business line typically has a lifetime warranty), you can make a warranty claim, and have it replaced. Secondly - it's perfectly legal for the manufacturer of a product to determine how long they will provide "free technical support", and it's industry practice to charge for support once that period has expired, and also to sell extended support contracts for people who need them - the 90 day period is documented in the paperwork supplied with the product.
