HP Pavilion dv3-2155mx review: HP Pavilion dv3-2155mx

The Pavilion dv3-2155mx posted the second-best battery drain test score in our roundup of retail-specific back-to-school laptops, trailing only the Pavilion dv4-1465dx and its massive 12-cell battery by a mere 17 minutes. The dv3-2155mx uses a smaller and lighter nine-cell battery and still crossed the 5 hour mark on CNET Lab's demanding battery drain benchmark. You can expect even longer performance under more typical Windows use where you aren't taxing the system by playing a video; it ran for over 6 hours when we were working on this review, which included near constant use and required the Wi-Fi to be enabled as well as the playback of audio and video files. Given the heft of the dv4-1465dx, the dv3-2155mx represents a better balance between portability and battery life.
