Clever use of laptop battery

Use rechargeable batteries for laptops, one of the advantages of the desktop, it can greatly facilitate a variety of environments using laptops. Introduced the first battery is nickel cadmium batteries (NiCd) battery but has a "memory effect", each charge is required before the evacuation, very easy to use, and soon found himself nickel-metal hydride battery (NiMH ) replaced, NiMH not only failed to "memory effect", but can do more per unit weight of 10% of electricity. The battery most commonly used is lithium-ion battery (Li-Ion), it is also ineffective "memory, compared to NiMH per unit of weight gain more power, the price two times higher than the NiMH . In the same weight, these three kinds battery is 1:1.2:1.9 ratio.


Notebook batteries currently used in three main categories: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium, they are generally expressed as: Ni-Cd Ni-Cd, Ni-MH Ni-MH, lithium-ion battery LI.


The purchase or replace the battery when the laptop for many users, "battery" may be unfamiliar. At the outset, batteries and batteries are two concepts. A battery is composed of several slightly bigger than your thumb, cylindrical, up to about 7.8 cm, 3.6 V voltage is small units. They are the batteries, as a small battery, thanks to the combination series, that is, we see that the battery a. Then talk about how to determine if the battery is several nuclei:


One way: Disconnect the battery for the number of contacts to see, there are a few tens of cores. But it 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, such 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 capacity of the battery pack, for example 3800mAh, then prove that the two aforementioned sets of batteries in series, because the battery capacity is 1500 small - 2000mAh, more importantly, to two to reach 3800mAh. In both cases, the battery is 4 × 2 = 8 cores.


The composition of laptop battery


Notebook battery from the shells, printed circuit boards and batteries belonging lithium ion battery. People talk about batteries in general refers to the number of batteries in the battery mAh refers to the ability of the laptop battery.


Mainly by the protection circuit (or the secondary circuit protection), and the capacity of the circuits in two parts, the laptop battery charge and discharge management and safety.


Time Laptop Battery standby mainly by the value mAh decide. Under normal circumstances, a little more battery, the mAh value is greater than longest standby time. Battery life for notebook mainly by the charge and discharge times to measure the quality of the products are generally eligible to 500-600 times. Therefore, efficient use of laptop batteries within two years expired the battery is aging, standby affect the strong decrease of the mobility of laptops.


Laptop battery advice


Indeed, how to make good use of the battery Batteries, how to extend his schedule and use of living and so on, is undoubtedly the troubled mind of the majority of laptop users, a problem the use of laptop batteries There are many methods and techniques that we use usually requires more learning and application.


(A) quick 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 enter sleep mode after a period of time, but more or shorter will wait a few minutes, there is no way to make the system of the laptop immediately enter the sleep state?


Notebook computer system to allow quick access to the latent state of a simple method is to directly close the display. Press the representation would require little effort, you can make notebook computers to standby mode immediately and effectively save power. When you need to reuse the time, as long as the opening screen, the system automatically returns to pre-condition.


(B) the screen saving mode


TFT is the most important components of portable computer power to reduce its use of the battery when the power consumption, notebook makers have devised ingenious schemes, but generally are based on the screen brightness lower and even off the screen mode.


In some settings management of laptop power you can customize the brightness of the screen, most laptops with a shortcut keys specific adjust the brightness of the screen, typically 6 to 8-setting brightness level.


(C) energy saving settings


Office machines using alternating current, most people may not be the computer attached great importance to energy saving features, but need to use batteries for laptops, using the Energy saving features should be taken seriously. How to design computer hardware more energy efficient, not a user problem to be solved. The user can be installed on the computer of the efficient use of energy saving option.


Energy saving settings require the user to set two: First, the computer BIOS setup program on energy saving in the profile settings, the most important thing is that there Energy savings in many settings of the operating system and operations. In the practical implementation of computer systems, Windows systems should outweigh the energy savings settings in the CMOS settings.


1. BIOS power saving settings


In the CMOS settings, most had a "power savings", which may choose to "Maximum Battery Life" and "Maximum Performance" and other options. "Maximum Battery Life" is the recording power default setting mode. Computer power saving mode phones in several states such as Idle Idle, Standby (standby) mode Suspend mode suspend (sleep) mode. Laptops, these parameters were able to regulate energy consumption, mainly in computer power saving state, the timely closure of some without the use of system equipment. If the wait state, turn off the screen and hard drive, in hibernation, apart from a rigorous monitoring and the hard drive, but also the memory contents can be saved on the hard drive, basic maintenance system throughout the computer closed, once activated, or restart the computer, office will be refurbished and pre-hibernation state. The energy saving settings in the CMOS, mainly determined by mode waiting to enter standby Standby Timeout, set to enter Suspend mode from standby to suspend time Timeout. Travel BIOS Phoenix are the most common. Energy saving various BIOS settings may be somewhat 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. Windows Help file in the "management hardware and software" entries, there are two laptops equipped with energy-saving elements on "Manage Energy Use" and "use of mobile machinery "in the laptop power management." Energy saving settings in Windows, read the contents.


In the Windows "Control Panel", "power management click, 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 settlement "system delay", "close the Monitors", "Turn off hard disks" and other options. Another computer can control the opportunity to have some differences, options for the new plant and the latest computer software will be easier to implement, the detailed parameters should be based on characteristics of the computer and Windows files Help to complete.


In addition, if your laptop integrated infrared port, no time to ban it, it can be extended the life of the laptop battery.


(D) alarm settings


Set alarm battery time to prompt the user to record information. Is to click on Open "Control Panel", double-click "Power" option, point "alarm" menu bar, alarm, battery low "column, Windows 98 default is 10%, "a serious shortage of battery alarm" column, Windows 98 default is 3%, which may make appropriate changes as needed. Click the [Alarm Response] button, the warning "voice" and "displays" are selected, the "power level" May of time to select. Alarm limits so that when the battery is used, it will display a warning dialog and the buzzer alarm sounds to alert the user to record information about the delay. Finally click [OK] to exit the settings of power management.


(E) opens the energy save function


In the "technology of extended laptop battery life 'section, we introduce the energy saving feature is the use of processor technology, which allows the performance of laptops are playing with their life stack between the time to achieve the best balance.


Most new notebook models in both the BIOS of the processor energy saving technology have given support, is enabled by default, if not open until the Enter the BIOS will support the option to open OK.


(F) the use of third party software to monitor battery status


In addition to Windows built-in features power management, there are many utilities available to monitor the battery status. For example, PowerCenter is a power monitoring tool available for free download (http://me MBers.xoom.com / TimothyBug / PowerCenter / index.htm). Only 800kb, is designed for computer software notebook services. In addition to the amount of PowerCenter shows the percentage of battery, but also to show the actual time and hours of time can be used.


PowerCenter total of 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 available.


(2) CompactDisplay: in use is always above the window.


(3) MinimizeDisplay: PowerCenter reduced to make 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 warning time user, save the file being processed. In order not to waste electricity and CPU resources, PowerCenter to automatically detect the changes of state of the batteries.


(G) turns deliberately battery


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 box Power Management dialog, select the battery is empty feeding particular, all 3 of its ongoing options batteries are fixed forever, this laptop on the run to continue. Select mode, then enter the Alerts tab, lift the battery low and critical battery Warning check box is a check mark (yes, when the battery is low, the machine will not go into the suspended state). Then leave the computer running the CPU time of tasks, such as the computer automatically perform a number of computational complexity of the 3D demo program, so running out of battery remaining, of course, these disposal N Do not forget to unplug the AC plug.
