The Gateway NV51B05u ran for 3 hours and 51 minutes in our video playback battery drain test. That's decent for a budget laptop, but AMD's power-efficient Fusion platform has also raised our expectations, and this is the shortest-lived Fusion laptop to date. HP's dm1 and Lenovo's ThinkPad X120e both ran for about 90 minutes longer.

Gateway includes an industry-standard, one-year warranty. Support is accessible via chat or e-mail as well as by toll-free 24-7 phone line, although the support phone number can be hard to find on the company's Web site (it's 800-846-2301). An online knowledge base and driver downloads are relatively easy to find.
