Typically, a good quality keyboard that can withstand collisions, fatigue, work or even to violent action. Many people have the eating habits while working on the computer, if debris falls on the keyboard slot inside the debris only affect the touch of the button, then the water is fatal for the keyboard, the author because of this habit of Gai Budiao Continuous mortality several keyboard.

keyboard waterproof design
Since the keyboard, fear of water, then it should have a solution, because the structure of the keyboard can not be changed, printed circuit needs of film and conductive rubber in close contact, hermetically sealed, or the true sense of the water is very difficult. The current water-proof keyboard, there are two designs, one is to BenQ BenQ 52M-based hardware water drainage holes designed to ease the double insurance, which is BenQ BenQ 52M waterproof keyboard, waterproof patent, by improving the internal structure of the keyboard, the circuit board under the two films are better able to prevent water entering at the same time an increase in the rubber button on the edge of flume and drainage holes, so if not carefully pour the liquid will not damage components, but its costs are higher; another BenQ BenQ P100 species of the coast is to the keyboard-based, pure water system design, using a large number of drainage holes of high permeability, the water has not yet returned to the keyboard, the inner layer, it was completely discharged. Of course, we are talking about water, just water for life, some of the user to verify the waterproof keyboard, and even the entire keyboard soaked in water. Waterproof keyboard is not a dive keyboard, this and waterproof watch, diving watch difference is the same.

Battery types and features:
Nickel-cadmium batteries (Ni-Cd): It is used in laptop batteries in the veteran, but because it has a serious memory effect as well as the anode material used in nickel (Ni) on the environment will be toxic and cause pollution, so it is quickly was despise laptop, and replaced by a more superior nickel-metal hydride batteries.
Nickel-metal hydride batteries (Ni-MH): nickel-cadmium batteries with the same structural principle, but will be replaced by the cathode performance better, more environmentally friendly Compaq Business Notebook NX9000 battery HP 395789-001 battery HP 446506-001 Battery HP dv9700 battery non-toxic nickel - metal hydride materials. Although only a small change, but it has brought a dramatic increase in performance. It also has an unmatched to make the advantages of nickel-cadmium battery is memory effect was not obvious, so that so that we no longer have the memory effect for that nasty trouble and become more user-friendly. Although the performance of nickel-metal hydride batteries are very good, but with technological advances, it is lighter in weight and a higher energy density lithium batteries replaced, HP F4809A Battery HP nc8000 battery HP nc8230 battery HP pavilion zd8000 battery HP f2024b battery become the laptop battery in the history of deadwood.
