HP ProBook 4440s 4441s 4545s -business laptop


LENOVO IdeaPad U310 keyboard surface and the body cap, like the matte black material looks very low key. On both sides around the top of the keyboard for our Express Gate start button and power switch.

The cooling vents of the machine was designed in the bottom of the screen, the middle part of the two shaft. In fact, this design is not appropriate, the aircraft screen shaft sinking design, in the case of fully open screen will have the whole heat some impact.

Notebook keyboard input devices we use every day, and its use feel a direct impact on the entry efficiency. LENOVO the IdeaPad The U310 provides the most widely used chocolate keyboard, the key process and rebound efforts in the chocolate keyboard a relatively good performance, but the overall feeling a little more rigid.

LENOVO IdeaPad U310 touchpad area about the size of a bank card, the surface of the palm rests similar was relatively smooth matte texture, finger in the above slide, and the use of the touchpad buttons feel better. In addition, the IdeaPad The U310 also set in the middle of the touchpad buttons, fingerprint identification device.

LENOVO IdeaPad U310 fuselage on both sides provides us with a USB3.0 interface, two USB 2.0 ports, HDMI interface, VGA port, and RJ45 network interface, the overall interface configuration is more practical, but a USB3.0 unable to meet the needs of copies of each other for two USB3.0 HDD.

Currently testing LENOVO IdeaPad U310 and Ivy Bridge processors using Intel's latest release is still selected the previous generation of Intel Core i5 2450M processor, with 4GB of memory, 640GB hard drive and entry-level discrete graphics 610m graphics card, the machine hardware configuration is notebook of the more common combination.

LENOVO U310 with a 6cell LENOVO IdeaPad U310 battery equipped with Core i5 2450M supports Intel Hyper-Threading Technology, and Turbo 2.0, CINEBENCH R10 test focused on processor performance test, the score of its multi-threaded 10398, in the current mainstream processor at a medium level.

The machine's power switch is placed in the upper right part of the C surface, next to the power button is a three function indicators, from left to right are the caps lock indicator, hard drive status indicators, as well as the wireless network status indicator. The aircraft is equipped with a webcam, but the microphone is not placed at the edge of the camera, the keyboard Shift key while in hiding the edge.

Interface configuration, the HP ProBook 4440s features the interface is quite comprehensive. The left side of the fuselage, from left to right is the power connector, RJ-45 connector, two USB 2.0 interface and an audio interface. From the left side of the fuselage, we do not see the vents, the overall layout is relatively simple.

The right side of the fuselage, we still found no cooling vents, where some VGA video output port, HDMI high-definition interface, a USB2.0 interface and a multi-card reader. The layout of the fuselage right side of the interface with the left side of the interface is roughly the same side back-end design.

A nominal value of the diameter of the corner of the yuan coin is 19mm, the ProBook 4440s the whole thickness of just more than the diameter of a little can be said that this 14-inch notebook is relatively thin, as to the weight of how much, the following will be weighed.

For ordinary 14-inch notebook computer, the body weight control in 2.2kg, even relatively light and thin this ProBook S40H is controlled at less than 2kg, electronic scales to weigh, you can see, this machine models with battery weighs only 1.769kg, the travel weight is only 2.096kg, to ensure the size of the screen at the same time, be able to compare light, which is where HP ProBook 4440s is commendable.

Hardware configuration, the get of this the HP ProBook 4440s battery is equipped with a 32nm system-way process of the Intel Core i3 2367M dual-core low-voltage processor, equipped with Intel HM65 chip group to configure the Hitachi 500G 5400 hard disk, and a single 4GB of DDR3 1333MHz high-speed memory, graphics cards, the model uses a graphics processor that comes with the Intel HD 3000 Core.

Before the start of the performance test, we first AIDA, 64 CPUID tool to look at this Intel Core i3 2367M processor, which based on 32nm process technology, the core code-named Sandy Bridge, the initial frequency of 1.4GHz, shared L3 cache is 3MB, the overall TDP of 17W, support Hyper-Threading Technology with the latest AVX instruction set.

Thermal performance test is actually super pole this is the biggest test of their own body interior space has been very narrow, coupled with the heat of a larger original heat patency became a test of a notebook's internal real effort, in accordance with established practice we have adopted a the FurMark software to make this machine to run at high load state.

Understanding of the basic information of the processor, we use the software CINEBENCH R10 its performance was evaluated, the software on a single processor and multi-core performance gives intuitive score, Fengyun Core i7 3610QM processor soon completed all of the contents of the tests, the end of its single-core 5715 points, multi-core 21134 points, a mobile processor high-end models.

The HP ProBook 4441s is equipped with a Seagate 500G 5400 rpm hard drive, through HD Tune and its performance was tested. We see from the screenshot of the test results, this hard drive average transfer rate of 64.7MB / s maximum transfer rate of 80.9MB / s, while the minimum transfer rate of 39.7MB / s, coupled with the access time of 18.2 ms its overall performance.

HP ProBook 4441s is a main cost notebooks, the aircraft is not equipped with discrete graphics, the new the IVB platform of the overall outstanding quality PCMark Vantage test aircraft, a 8068 total score, enough to prove the new platform for the whole band to the superior performance.

Graphics side, the upgrade of the 4441s with a 6cell HP ProBook 4441s battery SNB platform products 4440s, uses the same Intel Core Graphics, rather than entry-level discrete graphics. The HD3000's performance may be unsatisfactory, but the upgrade of the HD4000 is a great transcendence in terms of performance, running points and games have their own what kind of results?

Given the general users need to extend the life of the notebook would be the power management settings for power saving mode, before the test is so set, while prohibiting the notebook automatically reduce the brightness after a certain period of time to prohibit off the screen backlight, disable automatic sleep. At the same time, we let the WiFi remain open, which simulate the real use of state of the user.

After close to three hours time, the processor temperature to rise to 75 ℃, the core temperature reached 75 ° C and 72 ° C, Core Graphics, the temperature reached 90 ℃. Single sensor temperature from the point of view, for this thin and light, so the cooling efficiency is still quite good.

The final test results for five hours and 38 minutes, we can see, this HP ultra-pole of this ProBook in the low load state, continuous operation for nearly six hours. Whole life performance was good, the use of low voltage platform, this thin life in the forefront.

For a normal laptop, the cooling performance is of concern to most users. For a thin and light, the cooling performance is more important, can become a qualified light of this, in addition to the body thickness and weight, heat dissipation is critical.

In appearance, the HP 4545s A6C79PA Business this brushed aluminum display enclosure, magnesium reinforced ABS chassis and bottom of the drainage channels, prevent everyday wear and tear. Screen with 14-inch LED HD anti-glare display, 1366x768 screen resolution, equipped with gold screen ratio of 16:9, the picture is clear and realistic.

In the configuration, HP 4545s notebook uses a 6cell HP ProBook 4545s Battery the AMD Llano APU A6-3420M processor, clocked at frequency of 1.5GHz with AMD A70M motherboard chipset, standard 2GB DDR3 memory, 640GB 5400 rpm storage hard drive, built-in DVD burner AMD Radeon with 1GB memory capacity the HD 6470M + AMD Radeon HD 6520G graphics card, an integrated camera, preloaded with Windows 7 Home Basic 32bit home Basic (32-bit) systems.
