HP ProBook 4321s laptop Review April 13, 2010
Today we review on HP ProBook 4321s (WP415PA), is a 13-inch products. HP opened its 13-inch market in a big way, and foresight to select high-end consumer product and gave up the traditional 14 inches. This approach seems somewhat radical and risky.
Continue this strategy, HP ProBook s series also started to give up 14-inch size notebooks, focus on 13-inch notebooks. HP ProBook 4321s uses metal wire drawing process, and follows the overall angular style in edge.
HP ProBook 4321s body thinkness a slightly larger. The reason is mainly taking into account upgrading the hardware configuration, large body can provide a better internal air space of flow to ensure notebook cooling.
HP ProBook 4321s LED backlight LCD panel makes notebook looks thinner.
HP ProBook 4321s weights 2.2 kg with battery, travel weight of 2.7 kg. This result is not good. But as high-end processor and discrete graphics a premise, this weight is within an acceptable range.
HP ProBook 4321s uses the LED as a backlight screen, has improved in screen brightness, durability and energy efficiency. It should be made clear is that, LED backlight with LED screens are essentially different. LED backlight just upgraded the traditional backlight, but the screen itself still has not changed, not in the true sense of the LED screen. For consumers, in the process of buying laptops, also need a clear understanding of the difference between the two, avoiding business tamper with the concept.
HP ProBook 4321s screen thickness also worths encouraging.
Adult finger compared with the thickness of the screen.
HP ProBook 4321s is equipping with a camera at the top of screen. More special is that this camera provides not only shot the 200 million effective pixels, and supports face recognition technology. Users can pre-set the function, to achieve without a password simply by their facial contours can open the encrypted laptop, also better on the operation of the system security.
ProBook 4321s screen hinge is very worthy of our praise, the shaft embedded sunken fuselage structure in order to save space played a very good help function. Damping force and balanced rotor makes the opening screen of the operation can be completed only one hand.
Compared to most consumer products, HP ProBook 4321s base appears brighter and more compact. In addition to circle power button in the middle, HP ProBook 4321s has any shortcut keys, but all buy the FN key combination to achieve the shortcut function.
HP ProBook 4321s keyboard design also makes you very pleased with the performance.
The biometric fingerprint reader in the right palm rest of HP ProBook 4321s. HP ProBook 4321s really really out of business family.
We can see Energy Star, Windows 7 support, ATI discrete graphics and the latest Intel Core i5 Processor logo in the right palm rest are sufficient to show that this laptop will bring terrific.
HP ProBook 4321s touchpad supports two touch technologies. Through this technology, users can do a series of actions to achieve drag and drop page in touch pad with two fingers.
HP ProBook 4321s provided a very full rich interfaces. The fuselage on the left not only has VGA, RJ-45, USB 2.0 and other common interfaces, but also a common place in consumer products in high-definition HDMI digital interface, as well as commercial products E-indispensable SATA Interface.
The right of HP ProBook 4321s provides adequate space for mouse operation, HP just added two USB 2.0 interface, also filling with DVD recording drive. Interface layout can be quite reasonable.
Of course, the reasonable layout is not all. In front of the left fuselage, 4321s provides a set of audio input and output interface and a multi-card reader. Users without worrying about external headphone cable is not long enough, but can also facilitate the realization of the digital deposit card plugging.
HP ProBook 4321s has upgraded in the hardware configuration.
HP ProBook 4321s is equipped with a standard Intel chipset HM57, uses i5-520M processor, built-in south bridge chip to support DDR3 memory, with Intel integrated graphics.
We all know that in the newly released Core i-Series family of processors, i5 is the main mainstream product in mid-market, now includes i5-430M and i5-520M, the latter property to be slightly higher than the former.
HP ProBook 4321s is the one on the use of high performance Core i5-520M processor. Frequency at 2.4GHz, 2 cache 3MB.
As HP ProBook 4321s equipped with the ATI Mobility Radeon HD 4350 graphics processor chip which is relatively new, GPU-Z is not fully identified. But still basically tell its core GPU frequency of 450MHz, memory interface 128Bit, support DirectX v10.1.
HP ProBook 4321s pre-installed with Windows 7 Home Basic 32-bit OS. We do PCMark Vantage test in this OS to realize the overall performance of HP ProBook 4321s. The results show PCMark Vantage final score is 4934 points, which indicates that the overall performance of the 4321s has been completely beyond the previous generation notebook products, can meet most consumers of most everyday applications and entertainment needs.
We will do several major individual performance test, including processors, graphics cards, hard drives, and internal body surface temperature. Processor performance will be completed by CINEBENCH R10, main test of i5-520M single, multi-core processing power under the data; 3DMark Vantage will give a presentation ATI Mobiltity Radeon HD 4350 for 3D graphics and gaming performance; HD Tach test data notebook reading ability and stability; the final FLUKE thermometer and EVERest sensor will bring out the body surface and internal heat dissipation.
First, test processor computing power, adjust the notebook power management to high-performance mode, turn off the processor resources occupied by a large software and startup items.
In CINEBench test, Intel Core i5-520M single-, dual-core score was 2928 points and 6820 points, the performance is not only far beyond the previous generation processor, and also higher than the level of i5-430M with nearly 25%. In addition, because support for Hyper-Threading technology, and Core frequency of HT technology, multi-core computing processing shown while testing the software with 4 core course work, compared to i3 and more obvious advantages.
Although HP ProBook 4321s with the graphics is not high-end products, but by the parameters of the model and previous description can know its 3D performance is mid level should belong to the mainstream. Therefore, in 1024 × 768 resolution Entry mode, the laptop scored 4327 points in the results, able to cope with a level of3D World of Warcraft game, and can run smoothly under moderate quality.
HP ProBook 4321s uses Western Digital 320GB hard drive in the HD Tach tests performed satisfactorily, with an average read speed can reach 72MB / s read speed and stability compared with similar products are excellent. Thanks to the hard disk speed specification 7200rpm, test scores and almost the same as ordinary desktop PC.
Finally, at room temperature 26 °environment, we use the Fluke thermal imager and EVERest sensors running at full speed after 2 hours of 4321s to the fuselage surface temperature and internal temperature of the test.
HP ProBook 4321s review summary
As a 13-inch product, although HP ProBook 4321s in terms of weight and body thickness remains to be improved, taking into account is equipped with Intel processors and discrete graphics in the end, we do not need too much in this respect to its stringent requirements.
The other hand, in the fine craft and fashion and under the appearance, HP ProBook 4321s still has a relatively strong performance also allows us to see the development of a new trend in business notebooks. This is precisely the greatest advantage of this notebook, also an important reason for success of HP ProBook 4411s and HP ProBook 4310s based on the market.
HP ProBook 4321s advantages:
• metal wire drawing process
• body detail and excellent cross consumer, commercial product
• Performance of a broad population balance is good enough
HP ProBook 4321s disadvantages:
