HP ProBook 4710s
Keyboard and Touchpad
The full-size keyboard in the 4710s is a new project that HP has introduced the launch of the ProBook series. The keyboard has an extra space between the individual keys to help reduce errors and also includes a numeric keypad (a big advantage for companies that use their computers for complex calculations or data entry). Each key is relatively flat with a nice matte texture and the keys sit on a shiny black frame support. The support frame around the keys is quite strong, thanks to the chassis design, which adds additional support for the keyboard. The only clear area of flexible keyboard when you press keys on the keyboard.
The height of the keys seems a bit "too, because it is so far above the frame surrounding dust or crumbs can be established between the keys. That said, it's a good keyboard. The individual keys are quiet, without cracking as you type. The release of each key is excellent, although some people do not like the flat, chicklet style keys. Overall, the keyboard is nice and big ... as provided for in a A1078 of 17 inches desktop replacement.
The touchpad is very sensitive to touch with a scroll area on the right side, which works exactly as it should. Touch texture feels good, but the plastic used seems to be the type that will grow over time wear and tear. The plastic touchpad buttons are the right size, but require a deep pressure to click. It would not be a problem if the area just below the touchpad buttons are recessed to allow the thumb to press the buttons at the bottom. Unfortunately, when you try to press the touchpad buttons your thumb hits the bottom of the laptop. This problem is compounded by the fact that if you press the outer edges of the touchpad can press the buttons without recording the fact, and then click OK.
We would also like to see a dedicated touchpad disable button (such as HP uses on their consumer notebooks) so that you can disable the touchpad if you use an external mouse.
The heat and noise
In normal use (web browsing or working on a text document) the ProBook 4710s remained relatively cold, but not very quiet. The exhaust fan does not seem to be a full volume when the handset is connected, so that staff can hear what sounds like a hair dryer away in a quiet office. This is exactly the same problem we observed with the Pavilion dv9000 Battery small, and we suspect that the fan is strong because there are sufficient air flow from the bottom of the frame. The bottom of the solid cell inhibits the air inlet for the cooling fan, so the internal components could overheat and the fan has to work harder. When performing tasks that stress the processor and graphics, the laptop fan is working hard to keep this laptop cool. Five minutes after running the 3DMark06 benchmark at the bottom of the laptop hotter than 110 degrees Fahrenheit.
Battery
HP ProBook 4710s offers an 8-cell battery, 63WHr. Longest 8-cell Latitude D420 Battery is above average for a laptop of 17 inches, but not surprising. During our timed tests, the laptop "HP Optimized" mode, and wireless active the screen brightness to 70%, the 4710s lasted 3 hours and 35 minutes before the critics. Battery life can be extended by reducing the brightness of the screen and use the "energy saving" power profile in Windows Vista.
