Knowledge of the first lesson notebook battery select and use
Notebook PCs have become a fashion, more and more people to give up the desktop
, start select notebook computers. Not only on its portability has great advantages, more integrated hardware so that it occupied the space even smaller. The most important reason is the use of rechargeable laptop battery is the relative advantage of one of the desktop, it can greatly facilitate the environment in a variety of laptop use. And with the level of progress in battery technology, long life time of the notebook after another. Today, let's talk about the laptop battery that point thing.
Large class commenced it!
We all know that as consumables, notebook battery is life. So select the notebook, an important factor is to see if your favorite books battery is not easy to use. How to choose a laptop battery so it? This problem should start with the basic battery from the laptop (hope that we persist in reading, although some very dogmatic).
1) There are several laptop battery
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.
2) the composition of lithium batteries used
Laptop batteries by the case, circuit boards and batteries, belonging to lithium-ion battery. Ordinary people talking about batteries means the number of batteries within the battery, mAh refers to the capacity of notebook batteries. Mainly by the protection circuit board (or secondary protection),
toshiba satellite pro a120 battery and the capacity indicator circuit composed of two parts, on the laptop battery charge and discharge and safety management.
3) Laptop battery life determinants
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.
See how the battery parameters 4) Key: laptop purchase, how to see the battery parameters
Buy notebook, consumers often see is the parameter list and quotation. Among the parameters on the laptop battery only one or two. That is, is not Li-ion battery and a few core. Tell you that the market is now the most common is the 6-ion battery. Normal life time, high-performance mode, up to 2 hours (except for those outside BT notebook).
A common understanding on, we see how it says on the battery parameters. Notebook batteries can often be seen 4400mAh, 2200mAh nominal value such as batteries, and I said just now is to determine the life mAh capacity of the key. I am sure there will be many of my friends think that the bigger the better mAh. But in fact not the case, the real master, a unit of battery capacity should be considered "Wh", its Chinese name "Wh." Of course, "Wh" and the "mAh" is a close
dell vostro 1500 battery relationship with the following formula: Wh V 1000 = mAh be noted that the measurement of electrical power consumption of the unit itself should be a power, that is, "Watt."
And the important parameter is the battery voltage, mAh, and watts of three parts, we can learn from this to select the laptop battery should be noted that the place is not the "mAh" but "Wh" and the voltage of a few. I give you from the Internet to find an example to explain this truth.
eg: the same is a 4800mAh lithium-ion battery voltage at 10.8V and 11.1V under different out of life embodied in the ability different, and this different from the "Wh" different. By calculating we can get the following equation:
4800 1000 10.8 = 51.84 (Wh)
4800 1000 11.1 = 53.28 (Wh)
It is obvious to see that 4800mAh 11.1V Li-ion battery in the battery life will be more on edge.
5) Key: Notebook Battery Tips
After all, promoting low-carbon environmental protection, energy saving. Therefore, we start from me, I will tell you that the following use of laptop battery tips.
a) do not have time, please sleep books
I do not start nagging, this point should be everyone's attention. When no laptop, let it enter sleep mode (off better ah!) This will not only help the battery life, and hardware for the books is a good protection. And, let notebook sleep is simple, lightly labeled books. Books will be well behaved in sleep, Is it too much trouble?
b) a suitable screen brightness can be
Adjust brightness of the interface
So many people are myopic, largely playing computer, watching TV caused. And the screen is too bright, largely caused by excessive stimulation of the retina before, causing the pupil distortion (I am not a professional medical school, and only want to remind you). Therefore, the screen brightness to suit their own on the line, after all notebook power management now the most important one is the screen brightness. Screen is too bright, of course, also more power consumption, which will shorten battery life.
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 the 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.
The following two settings to talk about this method:
BIOS interface 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. These settings on the laptop, was 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 settings may be different BIOS should read 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 option to have some differences, the new factory and the latest in computer software, the option will be more operational details of Shezhiyinggai under Diannaobenshen the Gongneng and Windows Help files Lai Jin Xing.
d) Note that the battery alarm
Laptop battery alarm function is now the standard functions, so the warning appears, immediately save the file in progress, or immediately shutdown. This battery is for the protective effect.
e) it more reliable software, the Guardianship
In addition to Windows built-in power management features, there are many tools available to monitor program use state of the battery. Here's a better software for everyone!
PowerCenter is a power monitoring tool, 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, save the file being processed. In order not to waste electricity and CPU resources, PowerCenter automatically detect the battery status changes.
f) periodically discharge the battery good "health"
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 the suspended state). Next, let the computer run a lot of CPU-time of tasks, such as the computer automatically runs some computational complexity of the 3D demo program, Zhe Yang will soon run out of battery power remaining, of course, Jin Xing Zhexiechuzhi not forget to unplug the AC Yao plug.
5) Key: fix battery Qiao Fang
Qiao Fang battery repair
In fact, sometimes the battery will be angry, that does not mean the battery is broken. Here are a coup save battery: battery refresh program to restore the battery's discharge time
From the Internet for everyone to find an example, let's use this example to teach you it!
A IBMThinkpad390/262650 based laptop, the distribution for the nickel-metal hydride battery (Ni-Mh) batteries, as usual discharge properly, leading to the battery discharge time is short, only less than 5 minutes, if the portable notebook computer to work, then it is very inconvenient, what can restore the battery's discharge time?
In response to these circumstances, we can use the IBM has launched a battery refresh program to refresh the batteries, discharge time to recovery, specific methods are as follows.
(1) the use of AC power to the laptop, the first to download the IBM ftp://fip.pc.ibm.com/pub/pccbbs/mobiles/ isbr01ww.exe provided TP390/390e/390x series of notebook computer batteries Refresh program.
(2) Restart your computer, press F8 to enter boot menu and select safe DOS mode.
(3) just download the files into the directory, the implementation of the battery refresh program isbr0lww, exe, reading the warning message, insert the floppy disk as required, and then press the Enter key to the implementation of the self-extracting operation.
(4) boot floppy disk with this computer, the screen appears StartingPC-DOS.. . Prompts.
(5) prompted unplug the AC power, the program will automatically be on the Ni-Mh battery discharge, discharge is completed, the system will automatically shut down.
(6) The battery temperature is high at this time, should not immediately start, after the battery cool for a while, plug the AC power.
(7) boot the computer with a floppy disk, the Autoexec.bat file will automatically run the refresh program, and ask the user whether to proceed. Select yes, press the Enter key.
(8) At this point, refresh process began to refresh the battery, the process soon, when the return to DOS prompt A:> when that refresh is complete.
(9) Shut down the computer, and charge the battery until the light turns green so far.
(10) The above procedure is repeated three times to get the best results.
6) Key: laptop battery maintenance
Road maintenance
1. When no external power supply situation, if the working conditions at the time being less than PCMCIA card slot, it is recommended to remove the card first to extend battery life.
2. Room temperature (20-30 degrees) for the battery the most convenient working temperature, the temperature is too high or too low, the operating environment will reduce battery life.
3. Can provide stable power supply environment, using a laptop computer, remove the battery to extend battery life by not correct. On the ASUS laptop, when the full battery charge, the battery charging circuit will automatically shut down, so the phenomenon of overcharging does not occur.
4. Proposed to conduct a three-month average battery power correction action.
5. To minimize the number of battery. The number of battery charge and discharge directly to the life of a single battery charge, battery on a step forward to retirement. Suggest that you use an external power supply.
6. Use an external power supply when the battery removed. Some users often plug in the power supply several times a day,
acer as07b41 battery and notebook computers with batteries, do more damage to the battery. Because each time access is equivalent to an external power supply to charge the battery once the battery life shortened by a naturally.
7. Electricity charge and avoid exhaustion after the long charging time. Regardless of your notebook to use nickel-metal hydride or lithium electricity, to power must be exhausted after the full (capacity less than 1%), which is the best way to avoid the memory effect. Lithium also have memory effect, but it is the memory effect than Ni-MH smaller Bale.
8. Peacetime Caution: When used in peacetime to prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the metal battery contacts, etc. happen.
