HP ProBook 4425s Review


Compaq 4425s is a portable version of small and medium businesses popular with HP AMD. Designed as a copy of his brothers and sisters 4425s Intel quad-core Phenom II has built-in ATI Radeon 4250.


Planning and construction

HP Compaq 4425s is a very clean and professional, brushed metal body with plastic. The current generation of Compaq panels are made of copper or dark bronze, and are available in all sizes, including models of AMD and Intel. Compared to first generation models with plastic is not displayed on the outside, the new design looks great and increases resistance to the Fujitsu fpcbp136. Polished metal finish is used throughout the notebook, including the top of the screen, wrist, and the speaker grill. To complete the order, not the metal surface covered with glossy black plastic, adding another touch of class to this elegant small mobile business.


Build quality is very good and a step away from the old model. Brushed metal cover gives a bit of strength 4425s, and a protective plastic screen cover in previous generations lacked ProBooks. The wrist and grill the president to show little or no flex under pressure, you may feel more strongly that the brothers of 15 inches or 17 inches. Keyboard tray has a certain flexibility in less pressure to avoid any problem in the more expensive models, the HP Pavilion. The frame looks and feels much better than the EliteBook series control first, but it was not until after the mobile professionals who use the league as a main ingredient.



Customers wishing to replace the component stirred a little fast. To access the processor, hard drive or memory system, which must be completely disassemble the Compaq 4425s. This HP businessnotebook SMEs have opted for a centralized support and maintenance, with very little work to end users. In terms of appearance, giving a clear view of the bottom, without access panels, but in terms of difficulty, which adds a lot of work to discuss the components. To open the system, remove the four screws under the Fujitsu lifebook t4010 battery, remove the speakers from the free throw, remove the four screws that hold additional keyboards in place, slide the keyboard up. This gives you access to system memory. To remove the hard drive and more than three screws holding the wrist rest in place, carefully slide the right to publish your clips. After being removed only to take more than three screws that secure the hard drive in place, and remove it (more than four screws holding in a cage). To upgrade to the Compaq difficult or confusing to say the least.



Ports and Features

Port selection on the Compaq 4425s laptop is very good for small and medium enterprises, with three USB 2.0 ports, eSATA / USB combo port HDMI and VGA, LAN, modem and headphone / microphone. Laptop is also ExpressCard/34 SDHC card slot, and for future expansion.


The screen and speakers

HP Compaq 4425s is a 14-inch WXGA panel (1366x768) with a matte texture. The LED-backlit display is color and contrast, on average. In our lab tests that measures the average difference 149:1, brightness up to 166 eggs measured in the center of the screen. The black levels are average of professionals, and show no signs of backlight bleeding at the edges. We also found no dead pixels on our review unit. The color saturation is the average for business notebooks, but short compared to some of the new consumer notebook with glossy cards. Somehow we need a compromise between the HP Compaq 6510b battery seem more comfortable and contrast, and glare and reflections on the glossy screen matte. Vertical viewing angle are average, with the colors start to reverse when the screen is tilted 10.15 degrees forward or backward. Horizontal viewing angle of color is best to stay faithful to about 50-60 degrees before the screen started to appear dark.


Compaq 4425s has stereo speakers mounted on the keyboard to the left and right of the button. Portable Speakers for professionals are ranked just above average, with clear high notes, and some media. Low frequency tones were not present at all, but many laptops without a subwoofer that is common. For users who want to experience some advanced audio, the laptop has a headphone jack and digital audio output via HDMI.


The keyboard and touchpad

Full-size keyboard is easy to get into the HP Compaq nx6125 battery and very comfortable for long typing sessions. Each key is relatively flat with a nice texture and matte keys sit on the gloss black frame support. The frame around the buttons are pretty solid with the chassis design, which adds further support for the keyboard. Some keys are quiet, no loud click as you type. The depth of each key is excellent, although some people do not like to eat in May, chicklet-style keys. The total space and the chosen design for the HP 4425s is very nice for a laptop of 14 inches, without a feeling of tightness of the buttons more.

Touchpad on the latest models of the ThinkPad button less Synaptics ClickPad. In our tests, the touchpad worked fine, with frames of great sensitivity. We will have a strange, if supported his finger on the touchpad, which is defined as the area to the right and left. While the finger is at rest in that area, the cursor movement would be incoherent and agitated. If you lift your finger on the touchpad, the abnormal movement is stopped and worked fine. During normal operation, the touchpad works well for multitouch gestures to float on the lower edge of the touch screen.


Performance and benchmarksN

HP Compaq 4425s AMD's Phenom quad-core equipped with a clock speed of 1.6 GHz P920 II. This configuration is used to meet or approach, at least performance and i3 i5 models are equipped with Compaq. In terms of overall system performance, it was a "little disappointed, pending the results much higher than what we recorded. In normal everyday use of the system works well when most of the software included with HP is not installed. Sony vgp-bps13a lag "bloatware" due to any action of the box. Windows boot time and application loads quickly helped drive a 7200 unit that comes standard.


ProBooks Compared with Intel and Intel integrated graphics, AMD Phenom quad-core II ATI 4250 integrated graphics has fallen behind in all our synthetic benchmarks. Compared with the Compaq 4520s, which is very similar to the scores have been slower PCMark05, 3DMark06 and wPrime. He also noted that every test has more power in relation to larger systems, Intel. Even if the contract of AMD quad-core of the current generation of Intel dual-core, is still struggling to keep pace.
