Notebook computer's greatest strength is its mobility, may not consider the space, the use of anytime, anywhere, which is Laptop Battery everyone's attention it like it's the most important reason that the notebook environment protection and energy will become an important factor in the performance reflects the notebook. Typically, the majority of notebook computers use of time can keep 2 hours or so, when considering the purchase of batteries but do not want to do another extension, no doubt, it is necessary to proceed from the energy saving point of view, today we have to share what's on the laptop power several small tips.
Knowledge of laptop computer batteries Keys picture shows Samsung NC10's Battery
Notebook batteries and life time of knowledge
Usually, the Friends of the Inspiron 6000 battery of sensitive point is the most direct - battery life. Notebook battery life calculation, there is a formula, namely: the use of time = battery electric power / computer total power consumption. Typically, the total power consumption can be obtained directly from the parameter table, while the battery-electric power will need to be calculated. Electric Power batteries also need to calculate a formula, namely: battery-electric power = battery capacity × DC voltage. These two parameters can remove the battery, see the battery on the back, as shown in Figure 2.
Samsung NC10 piece of the Internet in this battery battery capacity 5200mAH (5.2AH), DC voltage is 11.1V, so electrical power was 5.2AH × 11.1V = 57.72WH. (Note: mAH: Read as "mA", which in general as the capacity of the battery unit. At 1 mA current output, the use of 1 hour of battery capacity consumed by one milliamperes when called; WH: Read as "watt-hour "is Inspiron 9300 a unit of electrical power. 1 watt of electrical power consumption of 1 hour is one watt-hours.) Thus, to calculate the battery life, and assumptions: the total power consumption of notebook battery 10W (watts), electrical power for the 57.7WH, then its use of time = 57.7WH ÷ 10W ≈ 5.8H, that is 5 hours 48 minutes.
For the details of the performance of laptop battery, You need to understand several aspects of this. First of all, the formula we can draw from the same configuration (nearly) machines, electric power value is greater the longer the battery usage time. As such, the Friends of the terms of mobility as a prerequisite to purchase the books, the focus on the configuration should be similar to the total electric battery power. Second, is the "batteries" discussion, namely Cell. Most of the Inspiron 9400 Friends of the view that the use of 6Cell the battery must be better than 4Cell a long time, this visual impression is correct, but is the same as the 6Cell battery, large capacity, the use of time may not be president of a little more, because only two kinds of battery output voltage Like when the larger battery capacity, battery life was longer.
With regard to books, "batteries", where in-depth presentation. Books come from battery-powered batteries, the market can see the single-core, 3 core, 4 core and 6-cell battery, of course, there are more, such as: 8 core / 9-cell battery pack can be basically maintained around 8 hours electricity, but the mainstream is still a 3-pin, 4-pin and 6-cell battery.
Multi-core battery pack composition, mainly by the series-parallel connected, series mode as follows: constant power, voltage sum; parallel mode: voltage constant, the sum of 310-6321 electricity. Relevant details can be found in Figure 3. As an example of Samsung notebook product: 3Cell battery pack, only ND10 used; 4Cell battery structure serial-based, multi-use of previous generation products, such as X11, R20, etc.; 6Cell battery pack, the basic structure for the 2 and 3 strings, the main active products were used.
Books for everyday use in energy-saving tips
Daily use, some energy-saving techniques used could also help extend the life of our books, especially for some large power of "surveillance", the effect is very remarkable. First, the laptop computer LCD screen is a big power, lower the screen brightness can be very effective in reducing the power consumption, extending battery life, dark environment does not require a higher brightness, we can appropriately reduce it. On the keyboard, most models a combination of buttons to adjust the screen brightness for the "Fn + F6/F7", specific 310-6322 operations can be found in random instructions.
