Correct All Battery Know Some Misunderstanding

Mon, 29 Oct 2012 18:54:01 -0700

The laptop battery is one of the more important parts of the laptop, it directly determines your ability to work in the environment of the useless power. Dell Inspiron 15R N5010 battery is a relatively easy loss of parts, a lot of discussion around the topic of the use and maintenance of the laptop battery. But many people are still here side into some errors, I have some conclusions based on their own experience. The first to be fully charged and discharged three times. (And even some official user manual are so to tell you, this is a lot of people the inability Tucao place, the official mislead you..) Said first discharge, the harm to the Dell Inspiron 6400 battery, especially when the capacity is less than 20%, or even hang up directly to your battery over-charge and over-discharge, will cause permanent damage to the positive and negative electrodes of lithium-ion batteries a new battery fully charge and discharge to make your battery capacity marked change in the display of the computer end, but this change is not because you have to fully discharge the charge generated, so the actual capacity of your battery will not produce change, just mark values for calibration, but a charge-discharge cycle can be resolved. Plug the AC power using the notebook battery when not in use, the battery down. When you experience a sudden power outage, the laptop direct power off and you will damage this time of the laptop battery can be used as a ups. And do not use the battery does not mean that you can effectively extend the battery life. Save the Dell Latitude D830 Battery is not good, such as high temperature, low charge capacity, and is not used for a long time, the battery will cause some loss to even hang. And lithium batteries are provided with a control circuit, and does not proceed with charging when the full power, and this is a safety circuit. Every day the battery with a use allows the battery to maintain its vitality, increase battery life. Many people will say exactly how to protect a battery and let it not early on in the life of retired this problem. Battery life is determined by the number of charge cycles, so avoid frequent use of the battery can be said to be one of the most fundamental methods, means that in using the power of the environment as much as possible not to use battery power. To sum up, I summed up some Dell DF192 battery maintenance methods, I hope you can benefit from: 1.Not every time every time to fully discharge go charging when the battery is less than 20% of the battery is a damage. Personal recommendations to charge the battery in about 50% of the time is a viable solution. Once said that in some foreign websites, lithium battery fast charge is the best way to use quick release. 2 each periodically charging and disch[...]

Dell Latitude D620 Battery charge and discharge method

Thu, 18 Oct 2012 20:09:07 -0700

After some time, the battery will be aging. Specific expression of the resistance, in charge when the voltage across the easily charge control line sentence easily charge control circuit is judged to have full capacity of nature is "down". Relatively large due to the internal resistance of the battery, the battery in use after a period of time will be aging. Specific expression of the resistance, when both ends of the charging voltage rises faster, so it is easy to be charging control circuit is judged to have full capacity of nature is "down". The relatively large Dell Latitude D620 Battery internal resistance, discharge voltage drop, the speed, the system is easily mistaken for a voltage is not enough, the lack of electricity (in fact, there is no electrical discharge). Can be seen from the above description of the process of aging of the battery is a vicious circle, found faster battery working time off when they should exercise it, otherwise, sooner or later, will be finished. Battery charge and discharge: The first constant current lithium-ion battery charging, fast charging, the voltage reaches a certain value and then to constant voltage trickle charging. Laptops usually are not strictly constant-current charge monitoring device. Large load on the system when the charging current is small, whereas the large, the current from the AC power adapter power margin. Obviously, the system will charge the Dell DF192 battery and other components, such as CUP, hard drive, LCD and other competing energy sources. I tried to run side Superπ, while charging the way, found that the charge current varies between 0.70 ~ 1.70A, can not meet the requirements of the charging of the lithium-ion battery, so I worry about this kind of work, rechargeable batteries has been damaged. Do not operate the IBM statement on the request of the laptop charging is probably the reason. When you start charging, if we can select the charge mode, do not select the fast charge mode (Express charge mode) to avoid premature battery "full". There is a low battery prohibit the use of CUP's highest performance, in order to reduce competition for power. Laptop CUP support SpeedStep technology, it is best to install the driver (responsible vendors will be installed) to facilitate the adjustment performance. SpeedStep program icon is a blue flag, right-click on it to performance tuning options. Windows XP system, SpeedStep program will be problems, this time to rely on to adjust the program to modify the BIOS parameters or some brand dedicated software tools such as IBM laptop is very powerful. On the the lithium discharge or always-on, let the natural discharge better. It is best not to use physical methods (string resistors and the like). Not to say that this is not the only risk is relatively large, the internal protection circuit did not work, the entire Dell Inspiron 15R N5010 battery void the worst possible battery **, of course, this is unlikely. Circuit hidden danger is not possible, some of the big manufacturers have discovered the potential risk factors in the design and recycled through battery ** As for the mobile phone battery when you do not hear about. Small knowledge: In general, the laptop battery protection circuit parts are usually the voltage regulator block, control chip, insurance, and temperature probe. Temperature protection is usually a one-time internal fuse (some 130 ℃ fuse), used to monitor the voltage regulator block work. If the charging and discharging process, and immediately there will be a current temperature protection, the fuse blows, the battery inside the circuit for the off state, and unrecoverable. If you want to fix the only replacement temperature protection, but these shall only be such as temperature protection is difficult to find in the market. Discharge is to try small current discharge, the operation is let CUP spin-down, hard disk stall, the screen tune darkest (or close off), and then do not run any p[...]

Ubuntu 12.04 operating system how to improve notebook battery life and performance

Wed, 10 Oct 2012 19:20:35 -0700

The Toshiba PA3534U-1BRS Battery is a very important thing, good management, you can extend the usage time of the battery, thereby extending battery life. In addition to the default management options, Ubuntu 12.04 also provides several other less common management function of the battery, because it is not in line with all notebook to use, so it is not so intuitive you can manage to Here we look at Look at them.
First of all, we want to open the power management ALPM function, which is a SATA AHCI controller SATA connector in the I / O inactive period dropped to a low-power mechanism. Open a terminal window, enter the following command as root:

echo SATA_ALPM_ENABLE = true | sudo tee / etc / pm / config.d / sata_alpm

If you do not want to use this feature to turn it off, then enter the following command:

echo SATA_ALPM_ENABLE = false | sudo tee / etc / pm / config.d / sata_alpm

The second method of saving electricity is the cache compression i915 frame. Cache compression the i915 frame can reduce the memory occupied by the display, which reduces power consumption, open a terminal in the ~ / etc / default / directory, execute the following command as root:

sudo gedit grub

Inside after the the GRUB file was open, find the following line:

GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash"

This line:

GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash i915.lvds_downclock = 1"

Save and close the GRUB files. Then open a terminal window, execute the following command:

sudo update-grub

The third method we can use the Inter PowerTOP tool. Open a terminal window, type the following command as root:

sudo apt-get install powertop
sudo powertop

With this tool, you can connect the camera, DRAM, audio, network card, Wi-Fi, Bluetooth, SATA and MMC / SD devices are set into excellent power consumption and thus save power.

Finally, one has been provided to our understanding of the errors - we always thought that display a black background will save more power. In fact, it is just the opposite, a white background will be more power efficient. Your wallpaper to change a light colored try.Toshiba PA3788U-1BRS Battery




Proper care BlackBerry battery, rescue the battery undergoes

Sun, 07 Oct 2012 22:19:24 -0700

Math around you the number of mobile devices? Phone, MP3, Tablet PC, laptop computers, digital cameras, handheld, navigator and so on, these devices are in use mobile battery-powered, the battery life is the most worrying problem. Mobile phone, for example, in addition to the system power factor affect battery life, knowledge of how to care for the battery also must understand, unless you can bear to replace the backup battery or external battery, in fact, this phone like the iPhone battery can not be replaced . Battery maintenance is possible on a single charge-discharge cycles have little effect, but a long time there is contrast, lithium-ion battery, battery capacity, there will be a loss of one year or more after, and maintenance of the good battery wear and tear will be much better. Online before spread on the maintenance of a lithium-ion battery, but different opinions. Such as new battery to get it back will be filled with 12 hours and then emptying three times in a row in order to activate the maximum capacity, but also say that every month there must be a complete charge and discharge process is conducive to maintenance. Foreign Battery University website recently released an article on how to prolong lithium battery life, the new conclusions on the use of the battery. They claimed, after the experimental results show that the best way of maintenance of the lithium-ion battery is mild to use, quick release fast charge, which is similar to the use of mechanical equipment, the greater the frequency, the more the number, the loss of the battery becomes fast. The smaller the degree of depth of discharge lithium battery, use the longer, if possible, try to avoid frequent full charge and discharge. Users, your battery using the 10%, 20% charge can also be the best remaining battery charge in 50% of the time, but try to avoid the phone prompts to start charging the lack of electricity, no matter what the circumstances are not to run out of battery power. If you're out, try to use a larger capacity battery or mobile power. In addition, they also pointed out that the use of environmental temperature also have an impact on battery life (30 ℃) is too high or too low temperature will be formed on battery life loss. Such as regular laptop connecting adapter power usage, it is best to remove the battery to formation damage, actually this is not rechargeable batteries, because it is no longer charging after the battery is fully charged, do not pay attention to the bottom of the laptop use ventilation situation makes overheating, this is the impact the battery life of the murderer. Of course, if there is a better use of the environment or the cooling pad, the battery can be avoided in the blackout loss of unsaved data. Since 2007, I have used before and after the four BlackBerry, from the earliest 7290,8110 to present 8900,9530. In addition to the 8110 off once basin (scooped screen looked like water fish tank installed Bangang) and used the toilet KO outside out after one year, the other good. Used so far encountered only fault is the battery problem. 7290 spent two years later, the battery installed said no electricity, shut down automatically. Thought the cell phone is broken, look after the forums to know the battery life to startle. 8110 One day, the battery is installed a battery plus a diagonal red bar icon does not react, but two batteries at the same time so can not enter the system that the cell phone is broken. Later seen on the forum master introduction is not to regulate the use and maintenance of battery resulting in self-protection dormant (also advanced battery too much), resulting in reduced life expectancy or chaos charging, battery end. However, a lot of people on the forum said that a lot of crack battery dormant soil method "to try really effective. Metal objects to battery positive and neg[...]



Notebook lithium battery market first full automatic production line put into production

Fri, 28 Sep 2012 18:57:34 -0700

Lithium battery manufacturing leader, a NASDAQ-listed Shenzhen BAK Battery, Inc. announced yesterday, smooth mass production of China's first notebook lithium battery fully automated production line, the first phase of the project can produce about 2,000,000. Experts pointed out that, This means that the domestic lithium battery manufacturing enterprises to enter the Dell Inspiron 15R N5010 battery market, the to stride pace of diversification BAK Battery, expand into emerging markets. Notebook battery market potential Relative to the increasingly stable mobile phone battery market, notebook battery market will become a new growth point of support sustainable development of lithium battery market. According to an authoritative survey agency statistics,The laptop market in recent years to maintain a growth rate of 30%, supporting battery market capacity of at least 560 million per year, the annual output value of 180 billion yuan. Prior to that, in addition to Samsung, LG and two of possession of a small amount of share, the Dell Studio 1737 battery market is almost monopolized by Japan's Sony, Sanyo, Panasonic, three, the formation of the "Five male Deere" pattern, battery manufacturing enterprises in China no one to enter the field. Moreover, in recent years, foreign manufacturing giants virtue of abundant capital, technical superiority and diversified development potential in the field of laptop batteries, rapid expansion, rapid increase daily output from only tens of thousands to hundreds of thousands of dreams monopoly market . Among this market, the Chinese battery manufacturers actually poised For want Fengeng the cup of trapped in laptop battery safety design and performance consistency and high, never formed climate. The reason is: First, do not grasp the advanced key technologies, and the production process is not really fully automated, and basically artisanal production. To break the monopoly of the foreign brands "Build a laptop battery fully automated production lines, only imported coater necessary $ 1.5 million, far higher than the cost of an ordinary cell phone lithium battery production line not yet 150 million year profits down by the many small and medium-sized domestic battery manufacturing enterprises become castles in the air, on an automated production line. "made the first successful development of laptop batteries, chief operating officer and chief engineer of the BAK Battery, Dr. Mao Huanyu that domestic enterprises even if automation is also equal to the dummy, do not bring good economic benefits, the production battery is only used in the field of mobile DVD, power tools, etc., in the field of high-end notebook applications is still a blank sheet of paper. It is understood that the total market share of 90% of the notebook lithium ion battery, is composed by a single lithium battery series and parallel, very high battery core security and consistency requirements. Both sel[...]
