HP's dv4 is the mid-range, slightly more mainstream 14-inch laptop from HP which packs good features at a good price. The dv4 line is separated into two lines, the dv4t and the dv4i (out of production). The current generation dv4t features Intel's 2nd Gen Sandy Bridge Core processors, while the old dv4i features Intel's First Generation Core i3 and Core i5 processors. Currently, the brand dv4t line is actually less expensive overall than the dv4i (faster CPU, cheaper price, whats not to love?). If you're looking to save some extra money, go with the dv4t.
The dv4t come with a 14-inch screen that displays a 1366x768 resolution and can be LED backlit as an option. Windows 7 comes standard with a choice between Home and Professional editions.
Upgrade your dv4 with up to 8GB of RAM, a 500GB hard drive, and improved graphics chip if you're a gamer (although with the Radeon 6470M upgrade for $100, you might be better off looking at the HP dm4x or the Lenovo Y470). Built-in webcam, WiFi 802.11n, 10/100 ethernet, HDMI, VGA, DVD burner, and 3 USB (1 shared with eSATA) ports are found in a 5.2 pound 1.34-inch thick package.
Both dv4 models draw 65W-90W depending on graphics load. Battery life will depend on your configuration and what applications you run.
If you're looking for something a little larger, check out the HP dv6t.
