Asus K53E-B1 review: Asus K53E-B1

Review Sections

Annual power consumption cost

The Asus K53E-B1 ran for 4 hours and 41 minutes on our video playback battery drain test. That's good for a big 15-inch laptop, and well past our previous must-hit number of 3 hours. However, much of the credit must go to Intel's efficient new platform, and we've seen similarly impressive numbers from many of the other new Intel laptops from 2011.

Asus takes a step past most other laptop makers by offering a two-year standard warranty, along with a single year of accidental damage protection. Other PC companies typically give you just a single year for basic parts and service, and make you pay extra for any additional coverage. A 24-7 toll-free tech support phone line is available, and support info and driver downloads can be found on Asus' Web site, though the information can get hard to track down with so many different models and configurations.
