The most disappointing aspect of the Pavilion dv4-1555dx's performance was its battery life. Using a standard six-cell battery, it failed to surpass the 3-hour mark, running for 2 hours 49 minutes on CNET Labs' demanding battery-drain test. The Toshiba Satellite E105-S1802 is lighter but features a larger eight-cell battery that ran for more than 100 minutes longer.

HP backs the Pavilion dv4-1555dx with an industry-standard, one-year warranty. Toll-free telephone support is available 24-7 during your warranty period, and the HP support Web site includes real-time chat with a technical support representative. If you want to troubleshoot problems yourself, you can search through the site's thorough FAQ database.
