HP ProBook 4440s this cost-effective notebook compared to everyone not unfamiliar to us, the aircraft enthusiast hardware configuration, but the price of entry to the mainstream performance to win the love of many consumers. HP's former no longer, today's products, whether material or workmanship, as well as hardware configuration, we can use the "kind" to describe.
The IVB platform has been released, the market has a variety of notebooks using the platform. HP certainly would not pass up the opportunity ProBook in the 4441s and 4440s are the corresponding upgrade of this article for everyone to bring ProBook 4441s this cost-effective large-size notebook.
HP ProBook 4441s appearance continuation of 4440s design, the two biggest difference is that the ProBook 4441s with a new 22nm Intel IVB platform, has a corresponding increase in performance and cooling.
The appearance of the ProBook ProBook 4441s and 4440s, has been introduced in the previous evaluation, this is no longer more introduced. This mainly to the performance test, take a look at the geometry of the IVB processor performance, the changes to take a look around the HD4000 Core Graphics, measuring the cooling performance of a measure 22nm.
In terms of hardware configuration, the get this HP ProBook 4441s is equipped with the 22nm process technology, Intel Core i7 - 3610QM quad-core processor, equipped with Intel HM76 chipset, configured with Seagate 500G 5400 rpm hard drive, and 4GB of DDR3 1333MHz high speed memory, graphics cards, the model uses a graphics processor that comes with the Intel HD 4000 Core.

Intel Core i7 3610QM belong new IVB platform processors with 4 cores and Hyper-Threading Technology support to eight threads. The processor based on 22nm process technology, the core code for Ivy, Bridge, and the initial frequency is 2.3Hz, Core frequency to 3.3GHz, 6MB shared L3 cache, the overall TDP of 45W.
Thermal imaging devices, the surface temperature of the test surface of body C and D surface. Among them, the keyboard part in contact with the user frequently the maximum temperature of only 58.8 ° C maximum temperature of the bottom of the fuselage is 64.0 ℃. From the heat maps, we can see the red area the highest temperature, for the surface of the keyboard, the red areas are concentrated in the keyboard top right of the thermal window position, while the bottom is the corresponding ventilation slots. In addition to the high temperature of the cooling vents location, other parts such as the palm rest and other location of the temperature more comfortable.
Evaluation Summary: The HP ProBook 4440s uphold the supremacy of the advantages of thin, thin body, easy to carry, Moreover, strong battery life provide a strong support to go out to carry.
