myecpro-laptop battery

On the rational use of the battery and the optimization method, we were still all the hardware from the laptop to its own characteristics in terms of different categories. To say, let us first come to a notebook computer power consumption of the various hardware to make a simple descending sort, then followed by “LCD, optical drive, hard drives, CPU and memory, other (interface, external equipment, etc. ). ”

1.LCD LCD

While the LCD liquid crystal display was a lot of power than CRT monitors, but the public laptop hardware, it is indeed a power-hungry. Among them, and power consumption of these factors is directly related to screen brightness and display refresh rate.

A. display brightness
Entirely from the brightness of LCD screen panels placed in the rear of the back tube, so can imagine the level of lamp brightness caused by power consumption is certainly not the same. So if the use of battery-powered, in the visual to the extent permitted, as far as possible to reduce the display’s brightness can save some electricity. This is tantamount to breaking also been circulating in the middle on the screen the user to adjust to a full black background to reduce LCD power consumption of this is wrong. Make use of the background of a black background for those who fancy the system can indeed reduce consumption, and thus to some extent played the role of energy-saving, but doing so is highly unlikely that the electricity dell Inspiron 6400 battery savings, but also brought about is not the LCD , because no matter what the background, the brightness on the LCD in terms of there was no change.

Again, many users prefer to use the notebook computer screen saver, this approach may be to the CRT display also has a protective effect, but the use of battery-powered laptop is concerned, nothing can be said is basically useless . And now the screen saver can be said to do more and more fancy, when running the screen saver is far more system load, power consumption will naturally be even greater. Therefore, it is recommended you leave the computer when the LCD can choose to close or use the sleep function, or even shut down your computer. IBM customers are lucky enough, you can use FN + F3 directly off the screen:).

B. Display Refresh Rate
Many people know, LCD’s refresh rate is a parameter exists in name only, because there is no LCD display is flashing, the general notebook refresh rate is a fixed re-60Hz, increase the reduction is useless. But when we do some very fast screen refresh operation, but also will increase the power consumption. This explains why, as well as playing video games when the battery consumption will be very fast, in addition to CPU, graphics card and other hardware load increased, the repeated continuously scraper action is also a critical factor in power consumption.

But it is regrettable that this issue is basically no good solution can only suggest that you use battery-powered as much as possible and less time video, little play games.
For the IBM notebook computer, its unique power dell Inspiron E1405 battery management software can be adjusted BatteryMaxMiser laptop screen refresh rate, see figure below, IBM, one of the exclusive features.

2. CD-ROM
Many users that drive power consumption is mainly due to the laser head caused by the transmission power. In fact not the case, the laser head fired power although it will consume some power, but compared to motor rotation, it’s hardly anything.

Notebook computers already in the energy-saving drive up and down a lot of effort, we can feel is when the drive with a disk is idle, the motor will be in a very short period of time from the high-speed down to slow the last stop turning. But read the disc, motor will turn, turn on the motor power must be consumed. And notebook drive has a fault, and that is when the tape drive, or insert the CD-ROM will start buzzing onto the first few, which is to consume electricity.

In fact, this problem can be solved. In addition, when using the battery as little as possible the use of CD-ROM, it also can make use of a software called NeroDriverSpeed to reduce the drive speed.

This is a very good green software, no installation needed to run, in the NeroDriverSpeedOptions can click on “Detect” button to detect the speed of the current drive supported by the file, and you can choose the interface language. From the Language menu, we have seen this software can support Simplified Chinese display.

In the user interface, you can read on the CD-ROM drive access speed and the rotation time after the cessation of the definition and also can run the software the way detailed definition.

In addition, if your drive supports DMA transfer mode, you must remember that in the Device Manager will open this feature, but do not use PIO mode. This can effectively reduce the CPU market share to achieve the energy saving effect.

3. Hard drives
With CD-ROM is similar to the motor rotation is also a factor in power consumption, while the hard drive heads when the mobile will also seek to bring the appropriate power.
Laptop hard drive an energy-saving design that is, in a certain period of time when the user stops the hard drive read and write operation, the head will automatically go places, motors into idle state, but the weakness of this design is the hard disk heads at any time will be re - seek the use of the state since the detection of the hard disk. Heads every mechanical movement will bring a certain degree of power consumption, so in the power management process to “turn off the hard drive idle time” to set is very necessary.

If your laptop using IBMTravelStar hard disk, you can use a software called PowerBooster to implement energy-saving hard disk operation, the software interface is very simple, you just need to move about “minimum power consumption” and “Maximum Performance” Inter - The block can be drawn.

Another possible choose to update the hard disk model, because they can support higher data rate standards, but it also needs the support of the motherboard chipset. Is now generally possible to see the hard disk are supported DMA/66 and DMA/100 standards, although generally only for the speed of 4200 rev / min in terms of notebook PC hard drives, DMA/100’s role in the transmission rate is basically unable to show come out, because the hard disk’s internal transfer rate never reached. However, the effective reduction in CPU market share is concerned, it does have a great effect.

4. CPU and memory
The reason why the two parts together, is that they contain the role of the interaction between the hardware is relatively obvious. When the computer’s CPU speed is relatively high, the memory more hours, is actually waiting for CPU memory; and when the CPU speed is relatively low, the memory is very large, appeared to wait for CPU memory situation. In either case, would increase the system’s own operational load, while not conducive to energy conservation.

A. CPU
First of all, try to choose to use the mobile CPU for laptop dell Inspiron E1505 battery computers, because the mobile CPU for laptop computers made energy-saving design. IntelSpeedStep by our well-known feature is the one major feature, from After the P3-600Mhz processor, Intel Mobile CPU officially added this feature, which allows the use of battery-powered CPU to automatically reduce the clock frequency to run, thereby play a role in energy conservation. (Mobile Celeron processors do not have this feature)

IntelSpeedStep procedures:
If you are using Windows98/Me/2000 operating system, can go to Intel website to download and install SpeedStep program, the program interface to the CPU clock frequency can be defined, the user can use it necessary to specify the frequency of CPU is running grade. Such as IBM, SONY notebook brands such as power management program also provides a similar functionality, although the same is based on IntelSpeedStep, but to much more detail, providing a very rich theme of power saving mode to meet different usage needs. While the WindowsXP has been embedded in the program, but unfortunately, it does not provide the definition of the procedures manual, the system will be installed automatically by default after the end of the program to adjust the power management energy-saving programs for laptops, which is why many users feel to slow down the computer after installation of WindowsXP system, a one of the reasons.

If you choose this, your processor speed in any circumstances of Pao Bule:
This can only choose to:
TOSHIBA notebook computer power management program
Also, if the choice Pentium3 processor notebook computer, as far as possible to prefer a .13 micron Tualatin core Pentium3-M processor, as compared to the older .18 micron copper core Pentium3, a new generation of processor power saving and performance should be a lot of good.

B. Memory
Many people think that DDR memory power consumption than ordinary SDRAM memory, in fact, this is wrong, because they ignore
The use of DDR memory, notebook computers are mostly with the Pentium4 and NvidaGeforce (ATIRadeon) graphics card such as power-hungry, in the power consumption is not possible naturally small. But on its own in terms of memory, DDR rather than the SDRAM power consumption, since the work of DDR memory voltage is 2.5v, and ordinary SDRAM memory 3.3v.
Of course, the working voltage is impossible for us to change, and we can change only the amount of memory. According to the system needs to select the appropriate size of the memory becomes very important, otherwise there will be because the memory is too small, cause the system to a large number of hard disk as virtual memory space to read the situation, which naturally is to increase the power consumption.

The following are the various operating system memory proposals:
Windows98> = 64M
WindowsMe> = 128M
Windows2K> = 192M
WindowsXP> = 256M

5. Other (interfaces, external equipment, etc.)
We use USB, PCMCIA and other interfaces are electrically charged, so consumption of electricity is inevitable. Moreover, according to an external device used in power is also caused by the different would be different, such as mobile hard disk power consumption than the external mouse is great.

There is only one solution, that is, the process of using the dell Inspiron E1705 battery as much as possible to use less of those interfaces, except had to use. After the equipment used must remember to remove, because although the device to stop working, but the interface in order to maintain the status of communications equipment and computers, but also consume some electricity.

For some we almost do not have to interface, can be considered a temporary close it, pay attention to is not in the hardware device manager to disable the device properties, but to the CMOS settings to Disable. For example, our well-known infra-red interface, it will automatically open and then scan from time to time around the existence of infra-red equipment, but also that of power-hungry.

Finally provides us with a proposal that, in the hardware configuration to allow as much as possible under the premise of the choice of the latest operating system, because the energy-saving design, they are compared to the previous generation of operating systems necessary to improve the lot. In addition, the rational combination of Windows power management program or a notebook computer manufacturers of power management program specifically designed for energy savings are very helpful.

“Mobility” is a notebook different from a desktop is an important feature of. It is due to have this feature, so that the laptop battery in between inadvertently assumed the important task of maintaining the image. A lack of long-lasting battery life of notebook computers, it is impossible to assume a long mobile office needs. The lack of a strong battery to help laptop, its “Anytime, Anywhere” is the advantage has become even more irrelevant.

At present, many notebook computer users about the battery life is merely a preliminary stage, for exactly how to protect the battery and the rational use of the dell battery not and will not know. When these users complaining about battery life big time is too short or the battery life is not long at the same time is not the first from their own carefully look for the use of the usual reasons? Of course, the reasons causing these two issues did not rule out the factors that the quality of the battery itself, but the vast majority of cases the present point of view, man-made improper use is a very common situation.

Many people think that the notebook’s battery life calculated in accordance with life, but in fact not the case, the real factors that play a decisive role should be to fully charge and discharge times. This is not a special case of notebook computers, anything is true of all rechargeable batteries. Under normal circumstances, is currently widely used in notebook computer lithium-ion battery for about 400 charge-discharge life; Ni-MH battery life much longer can reach 1000 times charge-discharge, but has a strong electric memory effect, so although better than in the life of the lithium-ion batteries, but its status in terms of daily use, Ni-MH battery performance significantly better than lithium-ion batteries.

Like the human illness and death with us, the hp pavilion battery is in the gradual aging and eventually, after death. Therefore, the proper use and maintenance of the battery is particularly important.

Most of the new machines will be pre-filled into the cell a certain amount of power for use in the test machine, so when you hold the machine home, first of all to this part of the electricity to recharge exhausted after work. And every charge in the future must ensure that the remaining battery power is consumed as much as possible and then carry out clean.

If you need to save the battery for a long time on hold, then the batteries to ensure a certain amount of power left, all manufacturers remain as to whether the number of remaining capacity of the divergent views, but I suggest that you used to be full after power is saved as well; another long-term non-use of the battery at least once a month the depth of discharge and recharge is also necessary to be done, this is aimed at preventing ion battery has not been used in the case of a long-term loss of electrical activity caused by no longer re-charge.

Use a stable power supply in the computer environment, circumstances, suggest that you remove the battery while using a separate power supply. The goal is very simple, is to avoid frequent battery is not fully discharged in the circumstances under which charging. The environment we live in is not absolute insulation, so the battery even when not in use, will also appear a natural power, so that when the power re-connected, it will charge the  hp Pavilion dv2000 battery. This practice has a strong memory effect of nickel-metal hydride electric batteries injury is very large, although the lithium-ion battery electric memory effect is almost negligible, but the time will not fully charge and discharge a certain extent, reduce the battery life. Of course, if you use a computer power supply situation is very bad for the environment, do not do that, and the price of tens of thousands of notebook computers comparison, a battery is quite fairly cheap, pick up sesame seeds and melon on the uneconomical in .

Battery maintenance, no matter how, if the method in use shall not be treated, but also unable to play to its effectiveness. The same specifications as the battery, why in the daily use and the manufacturers promote the use of the time difference so much? This is a lot of users in a very puzzled after purchase a problem. Of course, this information does exist a number of misleading factors, because the vendors publicize the figures are tested under conditions of extreme power the results obtained, and our daily use is impossible to achieve this environment. Even so, a difference of time is not much, will normally be 10-25 minutes (just writing word processing, web browsing and other simple operation). There is also another one is probably some of the more power the user operations, such as watching videos, playing games.

Our clients often receive such advice: Your battery will not explode ? Batteries, as the core of notebook accessories, closely linked with notebook mobility and standby time. Laptop battery explosions occur frequently, the airlines since the early 2008, a total ban on the transport laptop battery, notebook batteries are Scared of getting everyone right. Laptop battery really is a time bomb around it? Let’s analyze the battery cause of the explosion, everyone will be a similar explosion on a relatively objective met.
    Notebook computer batteries from the shell, interface,dell Inspiron 1720  batteries and control circuit. From the interface to enter, we first see an important component - batteries. It is responsible for the provision and reserve power required for notebook computers. Came to batteries and notebook computers between the motherboard, which is the most crucial part - control circuit. Its working principle and design are very complex, responsible for controlling the battery at an appropriate time to start and stop charging, control and reasonable charge and discharge current, but also bear the battery capacity display and record the number of charging and discharging responsibilities. Current of the battery temperature is too high or too large, cut off the circuit exceptional circumstances, will provide protection. The quality of the battery basically decided by the control circuit. The following is the battery exploded a few reasons:

1. Batteries internal short-circuit
    Batteries itself is not too large currents of protection, if a single or multiple batteries, an internal short circuit in order to make batteries large current discharge. These currents will generate considerable heat, so the dell Inspiron 1721  battery produces heat, and then spread to other body parts. If the body is a plastic material, will be the case in high-temperature deformation and even burning, danger! Qualified in the factory when the batteries are rigorously tested. Battery shell commonly used flame-retardant material, is not easy to directly open flame. Where suspects are generally related to poor quality material.
2. Electric core cable short-circuit
    Battery internal structure compact, created an opportunity to  Inspiron 2600 battery. Between the batteries used in series and parallel circuits are very dense, and close to the batteries, batteries and a damaged skin lines, or cable off, they begin to “conspiracy” regarding the short-circuit, several batteries, together with a high The current discharge, caused by high heat causing the problems.

3. Control circuit failure
    Quietly planning a control circuit, so that the protection of some of their own failure, usually performed using all the normal fullness, charging, the  Inspiron 2650 battery abnormalities, high-current discharge cases, deliberately cut off the circuit, the temperature rise fires. Abnormal high current from the host part of the fault, leading to discharge the entire battery pack overheating and fire.

4. Heat and unexpected events
    Notebook overheating, fluid erosion caused by external short circuit, was struck by lightning, or abnormal voltage, etc., may suddenly exploded.
    Lithium-ion laptop batteries are generally battery life is 300-500 times charge-discharge cycles, the replacement battery how to choose? Battery manufacturers first wife, said: “I am!” Price generally at 800-2000 yuan; neutral batteries raised their hands high: “I am cheap!” Note that the original battery is very expensive, your pricing strategy at the global, neutral Battery cheap, cheap in low-quality materials, such as renovation of shell, used split mechanical and electrical core. Brand of non-original batteries do? Reasonable price, because there’s a global pricing strategy, but definitely cheaper than the neutral because the materials used and the same original genuine battery. Even if the above three kinds of batteries are not going to choose, but also strongly recommends against privately to a non-manufacturer specific repair shop to replace batteries. Fatal! Because laptop batteries using a liquid lithium-ion batteries, because the steel casing used to seal the hard way, the internal pressure of a huge, if the explosion can imagine how destructive.
