HP EliteBook 840 G1 and HP ZBook 14 Coming
Nowadays is already the beginning of December, in addition to the southern part of the provinces, most of the country have entered the cold winter months. In order to resist the cold, and many people have been put on a thick down jacket, coat, in fact, laptops, desktop computers, one computer in the winter requires a variety of protection - and maybe we might already be familiar with a variety of summer using a laptop Precautions But winter maintenance of the computer is the first time I heard it might be?
Summer temperatures for most notebook computers and other harmful products of PC users know, is it cold in winter no effect on the laptop? Certainly influential, especially in some cases need to be used outdoors laptop.
HP ZBook appearance of 14 relatively law-abiding , the body color of the metal surface using a grinding process design . The notebook 's screen is 14 inches , with a resolution of 1600 * 900 , and ZBook 14 with HP ZBook 14 Battery also uses LED backlit screen, in the light, brightness, sharpness , etc. have a good performance. ZBook configuration of this competition is one of 14 high-end market is an important weapon of the machine , the processor uses the fourth -generation Intel Core i7-4500U, clocked at 1.8GHz, Core frequency up to 2.7GHz. Memory is 4GB DDR3 1600, 500GB hard drive is a traditional hard drive, the hard drive also supports mSATA SSD extensions. For graphics , HP to configure the nVIDIA GT720 + Intel HD Graphics4400 dual graphics cards, by switching between graphics cards , allowing ZBook 14 between standby and performance more flexible control balance.
From a hardware point of view part , EliteBook 840 upgrade to fourth-generation Intel Core processor platforms , using solid-state hard drive, can afford high-load commercial applications. The appearance, 840 in the exterior design continues the EliteBook traditional black style, but in the details of the deal were minor adjustments, such as removing the cap on the charge , the sleep indicator , the shaft housing painted brown , etc. .
At the same time , HP EliteBook 840 Battery -enabled keyboard, the keyboard on the basis of a new generation , an increase of independent numeric keypad , provides full keyboard functionality ; with Windows 8 operating system designed area of large integrated touchpad , supporting Win8 optimization 20 kinds of gestures ; for everyday office users and those with special needs , launched a matte display with full HD version and equipped with 3K resolution versions ......
First, the impact of low temperature for the laptop battery is quite obvious, the best use of laptop batteries at temperatures around twenty degrees Celsius, generally should be between 0 ° C -45 ° C using a low temperature may cause the low battery power down quickly, affect the battery life of notebook computers.
Secondly, the low temperature insulating material so that the computer will become brittle, hard, laptop power adapter cable sheath are plastic, wire and plastic fire accident caused by the aging of everyone uncommon, but brittle, hard plastic is aging phenomenon. In addition, some users need to use indoors, outdoors notebook computers, indoor and outdoor temperature difference this time there may be tens of degrees Celsius (northern winter outdoor temperature of minus twenty or thirty degrees, indoor heating temperatures twenty degrees above zero). A huge difference in temperature can cause condensation inside the notebook and condensation phenomena: First, the device causes the metal to rust, and second, resulting in a short circuit components on the motherboard.
For low temperature may encounter, notebook computer users can use special high-capacity battery and a special cooling or heating mode. In the Northeast, Northwest and other cold regions, to ensure that the low temperature of minus 30 degrees below the battery resistance. Furthermore, the need to design the core member heating circuit, automatic heating at low temperatures. Before and after using a laptop outdoors in the winter, you can remove the battery first personal storage, so you can prevent battery loss of temperature problems.
Is worthy of recognition A50 with TOSHIBA Tecra A50 Battery frosted surface of the screen , this advantage matte screen for a business of this is particularly important , a good anti -reflective ability to protect better working comfort and efficiency. Although not as high-end A50 in the work area , but did not sloppy screen hinge design , the aircraft is equipped with a standard Tecra specialty metal hinge shaft, opening and closing the screen angle reaches 180 °, strong and durable .
In addition to the winter cold, dry climate for the North is going to affect your computer: dry climate is another way the humidity is too low. It should be noted that when the electrostatic problem - we have winter clothing, hair removal of static electricity to the situation, right? Winter is indeed very easy to produce static electricity, which is also a static to a computer can not be ignored hazards. 40V may damage static logic circuits, high static load on the disk drive will be dust in the air adsorbed to the surface of the disk, causing data loss and head damage.
Intel's new hardware platform release in nearly six months later , EliteBook most high-end T-series notebook has finally launched the next generation of products EliteBook T440 and T540, the first time we got the EliteBook 840, then we will take a look at the new generation of 15-inch T series What kind of change .
Overall , EliteBook 840 with HP EliteBook 840 G1 Battery inherited EliteBook excellent DNA, the overall design reflects the high-end business notebook should be noble, especially for business users who choose to move and hardware performance requirements are high .
Core temperature , we can see the maximum load state, the processor 's temperature rose to 82 ℃, while the core temperature of the graphics card is also about 80 ℃ . Although the core temperature is not low , then the surface temperature , how is it . How to determine the thermal performance is good or bad , the maximum temperature not represent anything . Absolute temperature cooling vents is the highest , if not , that is the only show that thermal problems. When most of the heat accumulation in the cooling vents near the position, and the other parts of the temperature is not higher than 40 ℃, it can determine the cooling system design is more reasonable. Most aircraft have accumulated in the heat dissipation vent position , but the maximum temperature did not exceed 60 ℃, and in our regular contact with the heat of the palm rest and keyboard area is not high , but also in the actual experience of comfort is more appropriate degrees .
Next, PACKARD BELL EasyNote LE Battery life was assessed , I believe this is a lot of business users are very concerned about. We selected test software is PowerMark, it PCMark, 3DMark , just as developed by the FutureMark launched . It will run a continuous loop of test scripts , including four common applications : Internet browsing, word processing, video playback , 3D games, so as much as possible close to the vast majority of the user's actual usage.
