HP ProBook 4510s notebook

HP generally impresses our editorial staff with the quality of the speakers used in their notebooks. Unfortunately, the speakers in the HP ProBook 4510s were less than impressive. Sure, the sound quality is good enough for watching a webcast or hearing system sounds, but the built-in speakers sound tinny and lacking a good range of highs, middles and lows. The highest volume settings are loud enough to fill with sound for a presentation, an office but audio sounds distorted at higher volumes.
Despite the weak performance of the built-in speakers, they are well placed above the keyboard to direct sound and the direction of the user.

The headphone jack on the 4510s works well with the two different brands of earphones I have during the test. No static or other noise was noticed through the jack besides imperfections in the audio source itself.

Keyboard and touchpad
The full-size keyboard on the 4510s is a completely new design for HP and provides fantastic spacing between keys for typing and a dedicated number pad (a major plus for businesses that use their computers for number crunching or data entry). Each key is relatively flat with a nice matte texture and the keys sit above a glossy black frame. The support frame surrounding the keys is that additional support for the keyboard added solid thanks to the design of the chassis. The only obvious area of flex in the keyboard is when you press button. On the numeric keypad Please note however, that we got a pre-production unit, and HP claims that the production units to support against flex shipments to customers have even better.
The individual key presses are quiet without loud clicking sounds as you type. The depth of each press of the button is excellent, but some people may dislike the flat, chicklet-style keys. Overall the keyboard layout is very nice for a 15-inch laptop.
The touchpad is very responsive to my touch with a scroll zone on the right side that works exactly as it should. The touchpad texture is okay, but the cheap material used is sure to develop wear over time and use. The plastic touchpad buttons are about the right size, but require a deep press to register a click. This would not be a problem as the area under the touchpad buttons was indented to the right side of your thumb on the buttons all the way down. Unfortunately, when you try to press the touchpad buttons with your thumb touches the bottom of the notebook and sometimes fail to register a click. Buttons This would be a simple thing for HP to solve by replacing the palm rest and touchpad with a new one that should be indented area. Below the touchpad buttons
