The Cache Work Principle of Laptop Batteries

Posted on May 11, 2012 by Yedda

A. Reading order

CPU to read a data from the Cache to find, if found, immediately read and sent to the CPU processing; If you do not find, with a relatively slow speed read from the memory and CPU processing, while this data where the data block transferred to the Cache, you can make vgp-ac19v25 to read the entire data from the Cache, without having to call to memory.

Read Cache hit rate is very high (most of the CPU up to 90%), means that the CPU to read the next data is read mechanism allows the CPU to 90% in the Cache, only about 10% need to be read from memory. This saves CPU time to read the memory directly, and also allows the CPU to read data without waiting for the basic. Overall, the CPU reads the data sequence is first Cache memory.

Two. Cache classification

The front of the Cache as a whole to consider the classification analysis. Intel from the Pentium Cache separate, usually divided into a cache L1 and two cache L2.

In the concept of the past, L1 Cache the Cache integrated on the CPU, known as the chip. , Also in the L1 Data Cache (I-Cache) and the Instruction Cache (D-Cache). They are used to store data and the implementation of these data, instructions, and two Cache can be accessed by the CPU to reduce the conflict caused by contention Cache to improve processor performance.

P4 processors use an advanced level instruction Cache – dynamic tracking cache. Sony Vaio computer batteries is directly connected to the execution units and dynamic tracking engine, dynamic tracking engine can quickly find the implementation of instruction and the instruction sequence is stored in the track buffer, thus reducing the decoding cycle of the main execution loop to improve the processing computational efficiency of the device.

Previous L2 Cache not integrated in the CPU on the motherboard or CPU integrated with a circuit board, also known as off-chip Cache. However, P III began the process to improve L2 Cache is integrated in the CPU core, clocked at the same rate, ending the history of L2 cache and CPU gap frequency to equal the performance of L2 cache and L1 Cache higher transmission speed. L2Cache only store data, regardless of data Cache and instruction Cache. CPU core does not change the circumstances, to increase the capacity of L2 Cache can make performance upgrade, the same core CPU high and low end points is also often play tricks on the L2 Cache, showing the importance of the L2 cache. CPU L1 Cache and L2 Cache only difference is that the reading order.

3. Read hit rate

CPU in the Cache find useful data hit, this time called when there is no CPU required for data in the Cache (miss), the CPU to access memory. In theory, a 2 Cache CPU, read L1 Cache hit rate of 80%. In other words, the CPU L1 Cache find useful data accounted for 80% of the total data, the remaining 20 percent is read from the L2 Cache. Can not accurately predict the data to be performed, the read L2 hit rate is also 80% (from L2 read useful data for the total data, 16%). Some data had to call from memory, but this is a very small proportion. In some high-end areas of the CPU (like the Intel Itanium), we often hear L3 Cache, it is the design for the data read L2 Cache misses – the Cache in the CPU with L3 Cache, only about 5% of the data needs to be called from memory, which further improves the efficiency of the CPU.

Cnvironmental teaching board to promote the new development

Posted on May 8, 2012 by Yedda

The shimmer quantum environmental teaching board to integrate the advantages of modern multimedia teaching, as a new educational technology, has been quietly walked into the school, walked into the classroom to promote mathematics teaching to continuously update the development.
Follow the principle of “people-oriented” the shimmer quantum environmental teaching board, from classroom teaching, the liberation of the students, and to promote classroom teaching towards a real and deep direction of reform. Glimmer quantum environmental teaching board is a new high-tech e-learning system, it can information and communication with the computer, connected to the computer projector computer’s content is projected onto a glimmer quantum environmental teaching board on the screen in a special the support of the application, you can construct a large-screen, interactive teaching and learning environment: either directly use the electronic pen on the whiteboard annotation writing, electronic pen can be used directly glimmer quantum environmental teaching in an interactive board to operate a computer realization of the projection display , screen annotation, whiteboard = B, write the computer operating the four-in-one, to make teaching easier and more interactive. It can be said that the the shimmer quantum environmental teaching board will play an important role in the primary and secondary school education information.
A powerful interactive features to optimize classroom teaching
(A) enhances the interactive nature of mathematics teaching
Glimmer quantum environmental teaching board Apple Powerbook G4 battery has a powerful interactive classroom teaching interactive technology possible and convenient to fundamentally change the teachers and students interact in a traditional classroom, laid for the establishment of students’ active learning-centered classroom teaching the technical foundation. Author Professor Yuan were aware of a lesson, students use the voting machine to vote choice, shimmer quantum environmental teaching board to direct feedback to each student’s answer, is very conducive to the author learned that the students grasp the knowledge points, so the author based on the answers of the students to explain. The application of the shimmer quantum environmental teaching board to improve the frequency of interaction of teachers and students to ask, especially digital lesson plans based on the the shimmer quantum environmental teaching board, the more teacher-student interaction and participation in the teaching process to facilitate the deepening teachingcontent and form of interaction.
(B) to enhance the flexibility of mathematics teaching
Multimedia classroom and more traditional use of the PPT, Authorware to design multi-media teaching, PPT, Authorware can achieve a certain degree of teacher-student interaction, but this interaction set expected by teachers in lesson preparation, its biggest drawback is that the classroom teaching often than the default of the teachers.When the classroom teaching – towel students to the issues raised and the PPT content, the teacher is difficult based on the actual situation, the random variable, the problems of students tend to be overlooked; set PPT regardless if the teachers concerned about the emerging issues, is likely to disrupt the The default order of teaching, can not grasp the progress of classroom instruction, dry leaves, t kinds of contradictions caused by the lack of flexibility of classroom teaching. Glimmer quantum environmental teaching board-based classroom teaching, lesson mainly to prepare the teaching material, lesson default real-time generated according to the actual teaching. Author to carry out the practice of consolidation of the parallelogram area, students and the end of each other corresponds to “not understand the concept, I promptly graphics rotate to allow students to fully appreciate the meaning of” corresponding “; to explore new knowledgesession, the students on the number of lattice quadrature method is somewhat vague, the author in a timely manner directly on the graph marked move to deepen the understanding of a way that students find the area of ​​the number of lattice.
(B) micro live the thinking of the students’ mathematics learning
Students can board in low-light quantum environmental teaching practical and personally experience the behavior is very conducive to stimulate students to participate in the initiative, students enjoyable learning at the same time, promote the development of their mathematical thinking. I coach parallelogram area when the number of lattice area, and by the direct demonstration of the students in the media, we can clearly observe the students’ thinking process: the students how semilattice how to spell a grid, why fight the process error, which is very help teachers implement individualized to allow students to demonstrate the thinking process directly to the media such as a school Teacher Chang taught reading link in the understanding ibook g4 batteries of large numbers, students with sub- -level method of reading the thinking process in the classroom clearly shown by teachers teaching accordingly, the enthusiasm of students is greatly improved, to change the students are forced to accept the knowledge of the situation of this class structure is completely changed, “the teacher, the students listen; teacher demonstration, students see; teacher questions, students answer a single form of students will become the love thought, love to learn.
Second, the use of abundant resources to improve the efficiency of the mathematics teaching
(A) make full use of existing resources, improve the mathematics classroom efficiency quantum shimmer environmental teaching board system itself, the preparation of the resource library, teaching teachers according to their own teaching needs and the flexibility to use existing resources, thereby increasing the density and efficiency of the classroom. Coach parallelogram area, I need to measure the base and height of the parallelogram Biao, I use the “ruler” to measure;, I directly use the resource library of transparent graph paper with the number of lattice quadrature; need the shape of a parallelogram, directly from the geometric template out of the parallelogram model. I observe the “round understanding of a class, other teachers also directly drag the compass of this tool to draw any size circle. University Teacher Chang taught a class understanding of large numbers, the direct use of the dotted line in the connector directly in large numbers above classification. In the repository of the the shimmer quantum environmental teaching board, as well as digital wall games, puzzle game, these in the classroom can be used, can greatly enhance the students’ enthusiasm for learning, will further promote the improvement of classroom efficiency.

Laptop Battery Repair Software to Optimize

Posted on April 17, 2012 by Yedda

This is a specialized repair some old people do not unplug the battery through the AC, as well as battery failure in a short period of time, there are instructions for use, try a Sony notebook, 15 minutes to change one and a half hours, see the text for two hours, with the Rising kill too toxic, and hope to be useful.
Usage: unzip, the notebook to start charging, run directly to the point. Charging is complete after a period of time will be displayed. And then shut down, unplug laptop power plug and re-boot, run the program, this time the software displays the discharge.The discharge end after a certain time, until the computer automatically turns off, and then plug in the laptop power supply, power to run the program, display the charging end and then shut down, unplug the power switched on, the program displays the discharge, wait until the shutdown date. More than a total of two rounds, usually 2-3 rounds a course so that the battery is basically back to really state.

Principle: for technical reasons, the battery would still have memories, generally lazy people like to plug the power at any time without remove the battery, cause each discharged began charging due to battery memory and battery internal control circuit “smart ”, the battery detection circuit that the energy of the battery is charged to the end of this short, and then cycle has been under the battery control circuit put the battery capacity is defined as low value. This software is to allow the detection circuit stop running, but not false memories, to re-true “full

Laptop battery maintenance

A. When no external power supply, if the working conditions temporarily use the card in less than a PCMCIA slot, it is recommended that remove the card first to extend battery life.

Two. Room temperature (20-30 degrees) is the most appropriate battery temperature, the temperature is too high or too low operating environment will reduce the battery usage time.

3. The use of laptop computers in the environment can provide a stable power supply, remove the battery for longer battery life by life is not correct. Asus notebooks, when fully charged battery, the battery charging circuit will automatically shut down, so it will not overcharge phenomenon.

4. The average of three months is recommended once the battery power correction action.

5 Minimize the number of cells

Directly related to the life of the battery’s charge and discharge times, a single battery charge, battery to retire a step forward. Suggest that you try to use an external power supply,

6. An external power supply when the battery removed.

Some users often several times a day to unplug power, and the laptop is equipped with a battery, doing more damage to the battery. Because each external power access is equivalent to charging the battery, the battery will naturally shortened by a.

Discharged after the charge and avoid charging time is too long

Regardless of your notebook use lithium or nickel-metal hydride power 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 a memory effect, but its memory effect than Ni-MH smaller Bale.

8. Usually use the Note

Usually used to prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid the battery contact with metal objects such as.

Movement Is Good for Sony Vaio Laptop Battery

Posted on April 11, 2012 by Yedda

Lithium battery maintenance:

The temperature not too high

If the temperature is above the operating environment above 35 ° C using the lithium battery, the battery power will continue to decrease in battery-powered time will not beas long as usual. If such a temperature, but also to charge the device, it will be even greater damage to the battery. Even the battery is stored in a hot environment, thequality of the battery will inevitably cause the corresponding damage. So, try to keep inthe fitness benefits of operating temperature is a good way to extend the life of lithium.

Too low is not good

At low temperatures below 4 ° C using a lithium battery, also found that the battery operating time is reduced, Some phones Yuanzhuanglidian in the low temperatureenvironment and even charge on electric. But do not have to worry too much, this is onlya temporary situation, unlike the use of high-temperature environment, once the temperature rose, the molecular heat of the battery and get back to the previous power.

Life is movement

In order to play the largest lithium-ion battery performance, and often need to use it, so that the electronic lithium always in flux. If you do not often use the lithium battery, be sure to remember to complete a charge cycle per month to lithium, do a power calibration, ie,deep deep release sufficient time.

The Proper Methods to Take Care of the Battery?

Posted on April 10, 2012 by Yedda

Looked just the introduction of the battery price and warranty, you are not to feel a little sensational, almost dare not use the battery. In fact, the correct way to use the battery or longevity. Here you talk about the use of methods:
(1) to activate a new battery
Want your notebook battery longevity, there must be a good start, which was talking about buying a notebook. New laptop battery should be the first boot with 3% of electricity (which is also common practice firms. The first time you open the notebook to buy, found that the battery is already full, must be used by others) at this time. You should not use an external power, battery power exhausted, until the shutdown, and then use external power supply. After returning home, but also the exhaustion of the battery and then charge, charging time must be over 12 hours, repeated three times, in order to activate the battery, so as to lay a good foundation for future use.
Minimize the number of battery
This method gives the feeling as if a little stingy, but it is also the most effective. You know, the battery charge and discharge times is directly related to the life on one charge, the battery to retire a step forward. Suggest that you try to use an external power supply, use an external power supply when the battery removed. Some friends of convenience, often several times a day to unplug power, and the laptop is equipped with a battery, doing more damage to the battery. Because each external power access is equivalent to charging the battery, the battery will naturally shortened by a. Take our webmaster adults example, his notebook is enough to buy in August 1999, and every day with <a href=”http://www.usbphoneworld.com/apple-a1181.html”><strong>Apple A1181</strong></a>, the arrival on the use of an external power supply. In August of this year, the laptop battery suddenly a problem of standby time from the original two hours plummeted to less than 1 hour, which is the battery ill the most obvious manifestation, he can only be used and held the money for a new battery. From now on, he would cherish the battery there is no longer with the battery to work, only necessary when using the battery. Monthly charge and discharge the battery, he said, in so doing we can extend the battery life but also to reduce the weight of the notebook’s sense. Webmaster adult lessons give me a wake up from the beginning of August, I no longer carry the battery.My notebook is full built-in models, to bring the weight of the battery is 3.2 kg, batteries or nickel metal hydride, weight 1 kg and more, remove the battery is the most effective way to lose weight for my laptop. Think of laptop battery that the price of money, I’ll wait for the poor or less better.
Discharged after the charge and avoid charging time is too long
Regardless of your notebook use lithium or nickel-metal hydride power to power must be exhausted after the full (capacity less than 1%), which is the best way to avoid the memory effect. Lithium saying no memory effect, I had instructions in Part businesses irresponsible misled. Lithium also have a memory effect, but its memory effect than Ni-MH smaller Bale. Mobile phone battery charging methods, when your laptop battery, try to avoid too long, the general control within 12 hours.
As to prevent exposure to prevent damp, prevent erosion chemical liquids, avoid contact of the battery contact with metal objects such as precautions, radium in it not much to mention.

Lithium-ion battery (left) and nickel-metal hydride battery (right)

Posted on April 9, 2012 by Yedda

Lithium-ion batteries can quickly popular and gradually replaced the nickel-metal hydride and nickel cadmium batteries for the main reasons is that the lithium-ion battery No memory effect, as long as 3-5 times the normal charge-discharge cycle battery can be activated, free of charge and discharge a viable greater individuality.
Lithium batteries activated do not like the nickel-metal hydride or nickel-chromium batteries need to charge more than 12 hours, just follow the standard time and standard way to recharge (4-6 hours), the laptop battery protection circuit to control the charge and discharge time of the lithium .
Moreover, even when you turn the computer off, the battery is always in the power consumption state. Laptop computer connected to the external power supply, the battery will start charging automatically by default. Every time you turn on or off, is the same as the battery is repeatedly charged and discharged, and friends must remember that oh!
,
Thinner and lighter lithium polymer battery, with a mass at the same time compared to conventional batteries
The lithium polymer battery mentioned earlier, such as unexpected polymer battery is lithium ion era after the most promising successor. The lithium polymer battery, also known as polymer lithium battery, compared to lithium in terms of ultra-thin, high-capacity, plasticity, and low cost.
Fifth, the laptop battery battery maintenance:
Your new battery in a discharged state and must be charged before use. The battery is internally set a power calculation processing software to calculate the power battery beginning should cycle (fully charge, then fully discharge) 2-6 times so that it reaches the maximum capacity. The charge and discharge process is as follows:
1 Set the power management options
Right click, choose “Properties” à “screen saver” à “Power”
① “power scheme” à when the computer power mode, select “never” use the battery first, the election of XX minutes “never” or “”
② “alert” when the power reduced to 10%, alerts issued a serious shortage of battery alarm when power reduced to 3%.
③ unplug the notebook computer and use the computer until the battery power runs out.
④ When the computer is off when the battery is plugged into the computer and charge for 4-6 hours. Battery red to 100%, and then discharging to 0%.
If the battery does not use more than one month, it is recommended to be removed from the unit and placed in a cool, dry, clean place to save. A resulted in recharge the battery if you do not use the words will eventually discharge. Place for some time, the battery need recharging. In the process of charging and discharging the battery fever is a normal phenomenon.

Laptop computer batteries usually last for two to three years

Posted on September 23, 2011 by Yedda

Extreme temperatures can negatively affect your toshiba PA3399U-2BRS battery. According to Moses and Nadel, you ought to not expose your battery to extreme heat or cold. Heat causes batteries to lose their charge quickly and cold batteries don’t perform as well. In addition, some Toshiba laptop computer batteries can detect when they have heated up much, and won’t charge even when the AC power is plugged in. The computer will display ‘AC power plugged in; battery not charging,’ in this case. If this happens, you can charge the battery by shutting down your computer and letting the battery charge while the computer is off.

If your laptop computer battery is not holding a charge and it is older than three years, think about purchasing a brand spanking new battery. Keep in mind to fully deplete and fully charge the new battery the first few times you use it.

In the event you have thought about all of these feasible Toshiba PA3535U-1BRS battery issues and find that they are not the reason for the issue, try taking the battery out and gently cleaning the contacts on the battery and in the laptop’s battery compartment with a dry, lint-free cloth. If there is no improvement, you may need to look in to updating the computer’s BIOS or using the recovery CD that came with the laptop computer to clear any internal issues that may be affecting your battery.
