Understanding, Clever Use Of Laptop Battery
Understanding, clever use of laptop battery
Use rechargeable batteries for notebook computers advantages relative one desktop, it can greatly facilitate the environment in a variety of laptop use. Introduced the first battery is nickel-cadmium battery (NiCd), but this battery has a “memory effect”, each charge must be discharged before, very easy to use, soon to be nickel-metal DELL 451-10326 battery battery (NiMH) are replaced, NiMH is not only not “memory effect”, and the weight per unit can provide 10% more power. The most commonly used battery is lithium-ion battery (Li-Ion), it is no “memory effect” compared with NiMH, get more weight per unit of electricity prices twice as high than NiMH. Under the same weight, the three battery is 1:1.2:1.9 ratio.
Currently the batteries used in notebook computers are three main points: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Nickel cadmium NI-CD, Ni-MH NI-MH, lithium LI.
Purchase or replace the battery when the laptop for many users, the “batteries” may be unfamiliar. At the outset, batteries and battery are two concepts. A battery is slightly larger number than the thumb, cylindrical, height of about 7,8 cm, voltage 3.6v small units. They are the batteries, like a small battery, in series combination, we see that the battery was. Then talk about how to judge the battery is the core of a few:
One way: unplug the battery number of contacts to see him, there is some core of a few. But it is the “minister” means. We take a look at “Cao Chong” is how “said elephant”: a look at how much of your battery v nominal, such as 14.4v, then divided by 3.6 by 4, then proved to be four batteries together in series. Then look at the capacity of the battery block, for example 3800mAh, then prove that the two groups mentioned above, the series battery, because the small battery capacity of 1500-2000mAh, or even more, to two groups to reach 3800mAh. According to the two judgments, then the battery is 4 × 2 = 8 cores.
The composition of laptop battery
Laptop batteries by the case, circuit boards and batteries, belonging to lithium-ion battery. Ordinary people talking about batteries means the number of DELL INSPIRON 5000 SERIES battery within the battery, mAh refers to the capacity of notebook batteries.
Mainly by the protection circuit board (or secondary protection), and the capacity indicator circuit composed of two parts, on the laptop battery charge and discharge and safety management.
Laptop battery standby time determined mainly by the mAh value. In general, the more the batteries, mAh greater the longer standby time. Notebook battery life mainly to measure the charge and discharge times, the quality of the products qualified for the 500-600 times normal. Therefore, the effective use of laptop battery within a period of 2 years, the battery will expire aging, the drastic drop in standby time of impact notebook mobility.
Notebook Battery Tips
In fact, how to make good use of laptop batteries battery, how to extend their use of time and the use of life issues, no doubt troubled by the majority of notebook users a heart problem, laptop computer batteries and use a variety of techniques, which requires us to usually use more learning and application.
(A) fast into hibernation
Temporarily using a laptop, in order to save battery power, we can set the power management program, allowing the system after a period of time to sleep, but shorter or longer will have to wait a few minutes, there is no way to make notebook computer system immediately enter the sleep state?
The notebook system quickly into hibernation a simple method is to directly turn off the display. Press the display is just little things, you can make notebook computers into hibernation immediately and effectively conserve battery energy. When you need to re-use it, simply open the display, the system will automatically return to operation as before.
(B) of the screen power-saving mode
TFT screen notebook computer power consumption is the largest Dell Latitude D610 Battery, in order to reduce its use of the battery when the power consumption, notebook manufacturers have different tactics, but in general are based on the lower screen brightness, or even turn off the screen method.
In some notebook power management settings can customize the brightness of the screen, most laptops can be adjusted by a specific shortcut screen brightness, generally 6 to 8 level brightness adjustment.
(C) energy-saving settings
Desktop using alternating current, most energy-saving features on computers may not be very great importance, but need to use battery-powered laptop computer for the use of energy-saving features should be taken seriously. How to design computer hardware more energy-saving, this is not a user problem to be solved. Users can do is set the computer to effectively use the energy saving option.
Energy-saving setting, there are two require the user to adjust: First, the computer BIOS Setup program settings on the energy saving mode; most important thing is there are many energy saving in the operating system setup and operation. Computer system in the actual implementation, Windows system should take precedence over energy-saving settings in the CMOS settings.
1. BIOS settings in the Energy
In the CMOS settings, has a large “Power Savings”, which can choose to “Maximum Battery Life” and “Maximum Performance” and other options. “Maximum Battery Life” is the default energy-saving mode setting. Laptop power saving mode in several states, such as the Idle Mode Idle mode, Standby Mode standby (wait) mode, Suspend Mode suspension (sleep) mode. Dell Inspiron 8000 battery computer these settings have been able to regulate power consumption, mainly in the computer into energy-saving state, the timely closure of the system without the use of equipment. If the wait state, close the display and hard drive; into hibernation, apart from off the display and hard drive, but also the contents of memory can be saved to the hard disk, the basic maintenance of the entire computer system shut down state, once activated, or restart the computer, desktop will accurately return to sleep as before. The energy-saving settings in the CMOS, mainly set by the Idle Mode to enter Standby Mode of the Standby Timeout time set by the Standby Mode to enter Suspend Mode of Suspend Timeout time. Phoenix BIOS notebooks are most common. Different energy-saving BIOS settings may be different, should carefully read the screen prompts.
2. Windows in the energy-saving settings
For general users, 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 notebook computers with energy-related elements: “Energy Management” and “use of portable machine” in the “management of portable computer power.” Windows energy saving settings before making should read the content.
In the Windows “Control Panel”, click “Power Management”, you can open the “Power Management Properties” dialog box. In the “Power Management Properties” dialog box, should be “power scheme” is set to “Portable / Laptop” and rationalize “the system to wait”, “close the Monitors”, “Turn off hard disks” and other options . Different computer can control the options have some differences, the new factory and the latest computer software will be more workable option, a detailed set of functions should be based on the computer itself and the Windows help file to be.
In addition, if your laptop built-in infrared port, not when Asus EEE PC battery ban it, can extend laptop battery life.
(4) alarm settings
Set the battery alarm in time to prompt the user to save the information. By clicking open the “Control Panel”, double-click “Power” menu, click on “Alert” menu bar “-battery alarm” bar Windows 98 default is 10%, “a serious shortage of battery alarm” bar Windows 98 default is 3% can make the appropriate modifications as needed. Click both the [alarm response] button, the “Sound Alarm” and “displays the message” is selected, the “power level” may from time to choose. Alarm limits so that when the battery is used, it will pop up a warning window, and the alarm buzzer sound to prompt the user to save information in a timely manner. Finally click [OK] button to exit the power management settings.
(E) open the energy-saving features
In the “extended laptop battery technology” section, we have introduced energy-saving feature is the use of a CPU technology, which allows play to give the performance of laptop battery time between its optimum balance.
Most new models of notebook computers are on the CPU in the BIOS in the energy-saving technologies to support, by default is turned on, if not open as long as the option to enter the BIOS will support the open on OK.
(F) the use of third-party software to monitor battery status
In addition to Windows built-in power management HP Pavilion ZV5000 Battery, there are many tools available to monitor program use state of the battery. For example, PowerCenter is a power monitoring tool available for free download (http://me MBers.xoom.com / TimothyBug / powercenter / index.htm). Only 800KB, is a notebook computer services for the software. PowerCenter also shows the percentage of battery capacity, but also to display the actual time and hours of time available.
PowerCenter total of three kinds of display.
(1) FullDisplay: In the open window shows detailed information, including the use of battery or AC power, the percentage of battery remaining and available time.
(2) CompactDisplay: in use are always in the top of the window display.
(3) MinimizeDisplay: to PowerCenter down to Windows task bar, the information displayed is relatively simple.
PowerCenter is also attached to a control center, made up of 6 warning. When the battery – down to a certain level, a warning to the user in a timely manner to preserve the documents being processed. In order not to waste electricity and CPU resources, PowerCenter automatically detect the battery status changes.
(G) intentionally used up battery
Run out of battery on a regular basis to ensure a full charge. If you need to completely run out of battery power in the specific practice: the Power Management dialog box, select the Battery Drain power of this particular model to all three Running on Batteries options are set to Never, this notebook is the computer on will continue to run. Select the mode, and then enter the Alarms tab, remove the Low Battery and Critical Battery Warning check box in the check mark (so that when the battery power is low, the machine will not enter ASUS A3 SERIES Battery suspended state). Next, let the computer run the CPU-time tasks, such as the computer automatically runs some of the computational complexity of the 3D demo program, it will soon run out of battery power remaining, of course, these disposal not forget to unplug the AC plug.
