While the company sells the HP Compaq 2510p with a nine-cell battery, our review unit arrived with two batteries, a three-cell and a six-cell unit, which it offers on other 2510p configurations but not on the model we reviewed. We tested both batteries. Like the nine-cell battery, the six-cell battery extends beyond the end of the system, but ran for an impressive 3 hours, 24 minutes on our demanding DVD battery drain test. You can expect even longer life under typical usage scenarios. We attribute the long battery life chiefly to the Compaq 2510p using an ultralow-voltage Intel CPU. Competing ultraportables from Sony and Toshiba with similar or identical ultralow-voltage Intel processors ran longer, but we believe most users will be content with the 2510p's battery life, particularly since you can safely assume the standard nine-cell battery will run even longer. The three-cell battery that's available on other 2510p models sits flush with the back of the system and ran for 1 hour, 38 minutes, or roughly half the time the six-cell battery lasted.
HP includes a decent, three-year parts-and-labor warranty with the system, although the battery is only covered for the first year. Support is accessible through a 24-7 toll-free phone line, an HP has a robust online knowledge base and collection of driver downloads, especially for their business systems.
