Use rechargeable batteries to use rechargeable batteries for laptops, one of the benefits of office, it can greatly facilitate a variety of environments using laptops. Launch of the first battery is rechargeable nickel-cadmium (NiCd), but has a “memory”, each charge is required before the evacuation, very easy to use, and soon found himself battery nickel metal hydride (NiMH ) replaced, NiMH, not only has no memory effect, but it can not per unit weight of 10% of electricity. The battery is the most commonly used lithium-ion (Li-Ion), it is equally ineffective “memory, compared to NiMH per unit of weight gain more power, twice the price NiMH. In same weight, the three kinds battery is 1:1. 2:1. 9 Report. notebook batteries currently used in three main categories: 1. nickel-chromium, 2. Ni-MH, 3. Lithium, they are generally expressed as: Ni-Cd Ni-Cd, Ni-MH Ni-MH, Lithium-ion LI. The purchase or replace the battery when the laptop for many users, “battery” may be unknown. Initially, batteries are two concepts. A battery is composed of several slightly larger than a thumb, cylindrical, about 7. 8 cm, 3 6. voltage V is small units. They are the batteries, as a small battery, thanks to the series combination, that is, we see that the battery a. Then talk about how to determine if the battery is different kernels: One way: Disconnect the battery for the number of contacts to see there are a few tens of cores. But he is a minister “approach. Let’s take a look at “Cao Chong” is how, “said the elephant”: the look of your battery nominal number of v, so that 14. 4V, then divided by 3. 6 to 4, then turned out to be four batteries together in series. And then take a look at the battery capacity, for 3800, for example, prove that the above two sets of batteries in series, because the battery capacity is 1500 small – 2000mAh, more importantly, to two reach 3800mAh. In both cases, the battery is 4 × 2 = 8 cores. The composition of the battery laptop battery laptop from shells, printed circuit boards and batteries belonging lithium-ion battery. We talk about batteries in general, refers to the number of batteries in mAh refers to the ability of the laptop battery. Mostly from circuit protection (or protection of the secondary circuit) and circuit capacity into two parts, the battery cell and discharge management and safety. Battery standby time mainly by the value mAh decide. Under normal circumstances, a little over a battery, the mAh value is greater than the longer standby time. battery life for laptop mainly by the charge and discharge times to measure the quality of the products are generally eligible to 500-600 times. Therefore, the effective use of laptop batteries in the two years expired the battery is aging, sleep affect the strong decrease of the mobility of laptops. boards Notebook Battery In fact, how to make good use of batteries in the battery, how to extend its schedule and use of living and so on, is probably the troubled mind of the majority of users laptops, a problem of the use of laptop batteries There are many methods and techniques that we use usually need more learning and application. (A) rapid access to hibernation No temporary use of portable computers to conserve battery power, you can set the agenda for power management, allowing the system to standby mode after a period of time, but more or less wait for a few minutes, there is no way to make the system of the laptop immediately enter the sleep state? Portable computer system to allow quick access to the latent A simple method is to close the display directly. Press the representation would require little effort, you can make laptops in standby mode immediately and effectively to power. When you need to reuse the time, as the opening screen, the system automatically returns to pre-condition. (B) TFT screen saver mode the most important elements of the power of laptops to reduce its use of the battery when the power consumption, notebook makers have devised ingenious schemes, but generally based on the lower screen brightness and even turn off the screen mode. In some settings in power management for laptop, you can customize the brightness of the screen, most laptops with specific shortcut keys to adjust the brightness of the screen, typically 6 to 8 level brightness -setting. (C) parameters for energy saving office equipment using alternating current, most people can not be the computer attaches great importance to energy saving features, but need to use batteries for laptop computers, using energy-saving features should be taken seriously. How to design computer hardware more energy efficient, the user is not a problem to solve. The user can be installed on the computer of the efficient use of energy saving option. energy saving settings requires the user to set two: First, the BIOS setup program on the computer saving energy in the profile settings, the most important thing is that there are economies energy in many contexts operating system and operations. In the practical application of computer systems, Windows systems are expected to outweigh the energy savings settings in the CMOS settings. 1. to save the BIOS settings in the CMOS settings, most had an energy saving, which may choose to “Maximum Battery Life” and “Maximum Performance” and other options. “Maximum Battery Life” is the failure recording mode power control. computer power saving mode phones in several states, as Idle Idle (standby) mode Suspend mode Suspend (sleep) mode. laptops, these parameters were able to regulate energy consumption, mainly in computer power saving state, the early closure of certain facilities without the use of system. If the wait state, turn off the display and hard drive, in hibernation, with the exception of a rigorous monitoring and the hard drive, but also the contents of memory can be saved on the hard disk, system maintenance base throughout the computer shut down, once activated, or restart the computer, office will be refurbished and pre-hibernation state. The energy-saving settings in the CMOS, mainly on the standby to enter Standby Timeout, about to enter standby mode standby suspend timeout time. Travel Phoenix BIOS are the most common. The energy savings of various BIOS settings can be a little different, it should carefully read the screen. 2. Windows in the energy-saving settings for the average user in the Windows system to operate a better understanding of energy management can be simpler. Help file in the Windows Hardware Manager “software and” entries, there are two laptops equipped with energy saving features on “Manage Energy Use” and “use of telephony mobile machinery “in the management of portable power.” energy saving settings in Windows, read the contents. In the “Control Panel”, “click Power Management, you can open the” Power Management Properties “dialog box. In the” Power Management Properties “dialog should be” Power Management “is set to” laptop “and reasonable resolution” system delay “,” close “monitors” Turn off hard disks ” and other options. Another computer can control the opportunity to have some differences, the options for the new plant and the latest computer software will be easier to implement, the detailed parameters are based on the characteristics of the computer and Windows Help files to complete. In addition, if your laptop infrared port built, no time to ban it, it can be extended the battery life of laptop. (D) alarm settings Set the alarm battery to prompt the user to record information. is to click on Open “Control Panel”, double-click on “Power” option, point “alarm” menu bar, alarm, battery low “column, Windows 98 default is 10%,” a grave shortage alarm battery “column, Windows 98 default is 3%, which may make appropriate changes as needed. Click the [Alarm Response], warning” voice “and” poster ” are selected, the power level “may from time to choose. Alarm limits so that when the battery is used, it will display a dialog warning and alarm signal will sound to alert the user to record information about the delay. Finally click [OK] to exit the settings power management. (E) opens the energy saving function in the technology “of the laptop battery life ‘section, we introduce the energy saving feature is the use of processor technology, which allows computer performance Portable play with their battery life between the time to achieve the best balance. Most new notebook models, both in the BIOS of the processor energy saving technology have provided support, is enabled by default, s it is not open to the Enter the BIOS loads the option to open OK. (F) use of the third party software to monitor the battery status in addition to Windows Integrated Management Energy characteristics, there are many utilities available to monitor the battery status. For example, PowerCenter is a tool to control the power available for free download (Mbere http://me. Xoom. com / TimothyBug / PowerCenter / index. htm). only 800kb is designed for mobile software services. In addition to the quantity of PowerCenter shows the percentage of battery, but also to show the actual time and hours of time can be used. PowerCenter total three display types (1). FullDisplay: In the window displays detailed information, including the use of battery or AC power, the percentage of the battery and the remaining time. (2) CompactDisplay: in use is always above the window (3). MinimizeDisplay: PowerCenter reduces to the Windows taskbar, the display of information is relatively simple. PowerCenter is also attached to a control center may be composed of six types of warning . When the battery – to a certain level, a user warning time, save the file being processed. To avoid wasting electricity and CPU resources, PowerCenter to automatically detect the battery status changes . (G) turns deliberately short battery on a regular basis to ensure a full charge. If you need to run completely out of the battery in the specific practice is as follows: In the dialog box of Management power, select the battery is empty supply particular, all 3 of its battery options are being fixed for ever, this laptop on the run to continue. Select the mode, then enter the Alerts tab, lift the battery low and critical battery Warning box is a check mark (yes, when the battery is low, the machine is not in the suspended state). Then leave the computer running the CPU time of tasks, such as computer automatically performs a number of computational complexity of the demonstration program in 3D, so running out of battery power remaining, of course, these N removal Do not forget to unplug the power cord.
