Laptop battery life is how much time commonly, seem to have different capacity of laptop battery, laptop battery capacity how points, see in the introduction of laptops are based on actual usage, give me a about time or judgment.

The use time of battery or standby time:

4 core battery standby time is about 2 hours use time is about 1 hour or so

6-cell battery standby time is about 3 hours time is about 2 hours

Eight core battery standby time is about 3.5 to 4 hours of use time is about 3 hours

9 core battery standby time is 4.5 hours probably can use 3.5 hours

12 core battery standby time is about 5 to 6 hours probably use time is about 4 to 4.5 hours

Normally bought new laptop random with a battery of 4 core, need the capacity of battery advanced instructions required to add some money to buy!

Laptop batteries using skills

Laptop batteries in all cases, basically also took about two hours, how to use a good laptop batteries battery, how to prolong the using time and using life, is definitely on the mind of the notebook computer users to a problem, use methods and techniques have a variety of notebook computer batteries, that we need to use at ordinary times in the practice and application.

(a) rapidly into a dormant state

Temporarily not to use the laptop, to save battery power, we can set the power management solutions, make the system into a dormant state after a period of time, but it is long or short have to wait a few minutes, is there any way for laptop computer system to enter a dormant state?

Laptop system rapidly into a dormant state, a simple method is to close the screen directly. Press the screen just lift a finger, you can make the laptop immediately into a dormant state, effectively save energy of the battery. When need to use, as long as open the screen, the system will automatically back to the state before the operation.

(2) the power saving mode screen

TFT screen is use in laptop parts, in order to reduce its consumption of electrical energy when use battery, laptop manufacturer all the towers, but in general are used reduce the screen brightness, even the close method of the screen.

In the part of the laptop power management Settings you can customize the brightness of the screen, most laptops can be through specific shortcuts to adjust the brightness of the screen, usually have 6 ~ 8 levels of brightness control.

(3) energy saving Settings

Desktop using alternating current (ac), most people are unlikely to attach great importance to energy-saving function of the computer, but for the need to use notebook computer batteries to power supply, the use of energy saving features should be taken seriously. Of computer hardware designed to be more energy efficient, this is not a user to solve the problem. User can do is set the computer on the efficient use of energy efficient option.

Energy saving set up there are two place need to adjusted by the user: one is in the BIOS setup program of computer has set about energy saving approach; Is the most important thing in the operating system, there are many energy saving Settings and operations. Microcomputer system in the actual execution time, energy-saving Settings in the Windows system should be the priority in the CMOS setup.

 

 

 

Laptop battery in-depth analysis

Laptop how long charging time is appropriate for the first time, the merchant’s explanation is a must in more than 10 hours, to ensure that the battery fully activated. Although we are very careful to use our laptop batteries, laptop battery life is less and less. So how do laptop battery charging is the most appropriate?

Lithium ion battery cathode material usually has the activity of lithium compounds, the cathode is the special molecular structure of carbon. Main ingredients for LiCoO2 common anode materials, charging, and the poles of the battery in electric potential force release lithium ion anode compounds, embedded negative molecules are arranged in layers in the structure of carbon. Discharge, the lithium ions from the lamellar structure of carbon precipitation, and the anode compounds combining again. The lithium ions move to produce electricity.

Although chemical reaction principle is very simple, but in the actual industrial production, need to think about more practical problems: the anode material additives are needed to keep inflation activity many times, the cathode material of a structure at the molecular level to design to accommodate more lithium ions; Filling in between is the cathode electrolyte, in addition to the stable, also need to have good electrical conductivity, reduce the battery internal resistance.

Although lithium ion batteries have few nickel cadmium battery memory effect, principle of memory effect is crystallization, almost do not produce this kind of reaction in the lithium battery. However, lithium ion battery capacity will fall after is put in charge many times, because the original is complex and diverse. Mainly is the change of the anode materials itself, from the molecular level, is the cathode for lithium ion hole structure will gradually collapse, congestion; From the chemical point of view, is the activity of anode materials is blunt, and appear side effects to generate stable other compounds. Physically there will be the anode material peeling off gradually, and so on and so forth, all in all eventually reduce the battery is free to move in the process of charging and discharging lithium ion.

Overcharge and over discharge, to permanent damage across the electrodes of lithium ion battery, from molecular level, can be intuitive understanding, discharge will cause excessive release of lithium ion anode carbon makes the lamella structure there are stuck down, excessive charging will take too much lithium ion shoehorned into the structure of cathode carbon, and makes some of the lithium ions can no longer be released. And that’s why lithium ion battery is usually equipped with a charge and discharge control circuit.

Not suitable temperature, will trigger a lithium ion battery internal chemical reaction generating we don’t want to see other compounds, so in many of the lithium ion battery is between the cathode temperature control diaphragm is equipped with a protective or electrolyte additives. In battery heats up to a certain case, the composite membrane film hole closed or electrolyte degeneration, battery internal resistance increases until the cut-off, the battery no longer to heat up, make sure the battery temperature is normal.

And deep filling put will enhance the actual capacity of lithium ion battery? Experts specifically told me, this is meaningless. They even say, the so-called three full charge before use on “activate”, in Dr. Both of them knowledge, also can’t imagine what’s necessary. But why a lot of people after deep filling put ‘Information in the marked capacity will change? Will be mentioned later.

Laptops use lithium ion batteries are generally management with a chip and charge control chip. Which have a series of register management chip, has a capacity, temperature and the numerical ID, charging status, discharge times, etc. These values in use will change gradually. Personally, I think, in the instructions on the use of the laptop “use after a month should put a” full charge of the main part should be revised the improper value in the register, makes the charging control of electric pool and nominal capacity consistent with actual condition of the battery.

 

 

 

 

 

How to improve notebook Heat dissipation in summer

26. June 2013 · Write a comment · Categories: lapton batterier · Tags: notebook Heat dissipation

 

Laptop will meet as soon as I get to summer heat dissipation problem. Heat dissipation is bad can lead to the fuselage working temperature is too high, influence, including CPU, motherboard, hard disk, the stability of multiple components. However, heat dissipation is not good can say is the common fault of the laptop, in use process, how can we solve this problem? In fact, we can open a laptop directly clean up dirt from the fan. Fan because of the rotation for a long time, the air flow in various dust is inhaled, and accumulates on the fan blade, not clean for a long time can lead to heat up.

Soot is mainly to the outlet fan, dust cleaning work. Recommend that users use to clean suits in the soft brush to clean up the dirt on the blades, brush to keep dry. When dust cleaning blades, the fan first removed, so that can avoid the brush off dust fall inside the fuselage. In addition to clean up dust fan, also should have the outlet of the heat sink is clear up. Users only need to use the brush or the wet dishcloth to wipe off the each grille is ok, if there is a fan of the inlet, then along with the air inlet is clean.

Also remind everybody is, CPU and GPU by thermal conductivity silicone grease and heat dissipation module connection, laptop after long time use, thermal conductivity silicone grease will also ageing, thermal performance will be reduced accordingly. You can be in clean ash teardown at the same time, the change of thermal conductivity silicone grease or liquid metal. Replace the silicone need not too frequent, 1 to 2 times a year that can be. Replace thermal conductivity silicone grease, chip surface don’t apply too thick, so it will affect the heat dissipation, uniform coverage on the chip surface. Replacement of liquid metal is simple, do not need to apply.

Laptop batteries when using common pitfalls

25. June 2013 · Write a comment · Categories: lapton batterier · Tags:

 

Laptop batteries bombings appeared many, mostly appear in the shanzhai laptops. Even apple laptop made art manufacturers, has happened to the battery battery explosion. Therefore, you must get into the habit of the proper use of laptop batteries. Laptop batteries don’t like the timing of fenqing mouth * *, also is by no means do you want to how to do how to do. So we usually use laptop batteries need to pay attention to what aspects? I give you a detailed introduction:

1. Remove the battery, the use of the power converter

There are a lot of people like to unload the battery, through the power converter using laptops, to ensure the service life of the battery. Actually completely don’t have the necessary, because the laptop battery management chip after a full charge directly cut off the charging circuit. Besides some laptop computer after you remove laptop battery can not reach full speed running, when run some large program you will feel sluggish. If all of a sudden power outage, all your information is lost.

2. You will not for a long time to unload prolong battery life

Most think laptop batteries don’t have to remove the battery when, can prolong the life of the battery. Actually this idea is very one-sided. Due to the lithium battery is determined by its own characteristics, lithium electronic actually as long as the production line, the aging process has already begun. This could explain why a piece of a laptop battery didn’t charge electricity, why three years later will be completely scrapped. Objective point, batteries and cartridges, is also a consumption goods, but don’t expect your battery can as your hardware can be used for many years.

3. The new laptop charge 12 hours for the first time

When you buy a laptop, the clerk will typically give you said, your laptop first charging must be in 12 hours, so that to activate the battery. Must be the batteries need to be activated? At present our this battery is lithium ion battery, only the nimh batteries need such a long time the battery fully activated. Now the laptop lithium battery inside management chip is placed, as long as the battery voltage reaches the forehead at the ends of the rated voltage, the chip will cut off the charging circuit, charge again go down to just a waste of time and energy.

Laptop batteries comprehensive problem solving

24. June 2013 · Write a comment · Categories: lapton batterier · Tags: direct charging

Question 1: direct charging over the inside of the battery is unused, ok?
Answer: because the inside of the laptop most rechargeable batteries use lithium Ion batteries (Li – Ion), no memory effect, then you failed to use electricity use up and charge are the same, you don’t need to worry about. And buy something for use, can play to the role of the laptop is the most important, because afraid of damage not rechargeable batteries, that is the biggest loss.

Question 2: why my laptop batteries useless several times will be broken?
Answer: many laptop batteries have been inserted in the laptop, at ordinary times no life function, a direct use on adapter, this battery not bad just strange.
Whatever the service life of the battery are laptop battery life is calculated according to the number of charging and discharging. But many people don’t quite understand about this problem, plus regular laptop battery charge and discharge times are at least 500 times or so, so much so that many friends think laptop battery life is also about two years.
Even if don’t have to notebook battery, self-discharge phenomenon can happen, once placed a long time, can appear excessive discharge. Once at this point, many: I don’t think even the electric charge on the batteries, good carry of the battery, useless several times and died.
That is to say, even if your battery for a long time not use, also can’t dry, and over a period of time is a best charge and discharge, to maintain the “status” of the battery. But due to the lithium electricity itself also has a certain memory effect (usually said that it is wrong to li-ion battery has no memory effect, lithium electricity also has memory effect, actually just a small), it is better to will the battery inside the battery, then charge, so the effect will be better. Charging time, of course, the best control within 12 hours, otherwise the excessive charge will lead to a drop in battery life.

Question 3: why are 6 core 4400 milliampere batteries, some can use 3 hours, or a movie can not over, what is going on.
A: besides itself life battery problems, the laptop itself the power consumption is the key to affect battery life, be in the movies than text processing demanding, play 3 d games must be demanding, than watching movies be in open wireless than don’t wireless battery life, and of course the CPU power consumption design is also very important.

Question 4: why original batteries are more than 1000 yuan, buy inferior brand line not line.
A: a lot of friends have long battery life need, especially business people, the perennial on a business trip over ten hours of battery life are necessary, so the configuration in addition to configure a battery is necessary. What if can’t afford to buy original battery, not original? Remind you there are a lot of non-genuine counterfeit batteries, look exactly like the one with IBM, the performance is poor. So I recommend to buy home furnishings.

3 tips to teach you to improve the tablet battery life of the battery

21. June 2013 · Write a comment · Categories: lapton batterier · Tags: tablet battery life of the battery

Limited by current technical level and battery safety considerations, currently a tablet’s battery life (i.e., battery life) can reach ten several hours has been very good. Now on the market most of the tablet’s battery life under five or six hours, then decide if the battery life of a tablet computer what element?
First of all, a tablet used what type, how much capacity of the battery is the core of the decision its battery life factors, businesses must indicate the battery parameters is that we as a primary reference conditions. In general, the gauge plate is brand the most commonly used batteries for lithium polymer battery, because it has high space utilization, the capacity of arbitrary size variability, ultra-thin, high security, reliability and other characteristics, has become a high-end tablet preferred and eliminate inefficient subclass product such as mobile phone battery; Battery capacity is larger, then use the longer time.
Secondly, with enough good battery, the power consumption of the whole tablet runtime how to decide that battery life is also a very important factor, good machine hardware configuration package technology, can let the power consumption is reduced, makes the batteries will last much longer.
Finally, a tablet’s battery life is also related to users of some of the habits, can provide you some can effectively enhance the battery life using a small coup, such as the first battery charged again thoroughly after use, fully activate cells, after began to charge after the power usage to a few percent, avoid to cause the battery discharge; Reduce the screen brightness, and can also save electricity.

Use characteristic correction tool many laptops are built into the battery tools.
1, double click the power management icon in the taskbar, select “the longest duration” mode
2, select “the longest duration” mode 2, click “Settings” button, switch to “battery maintenance” Settings page, and this time click the “start” button, and then a prompt window will pop up, right now, please close all applications that process, and make sure that has been connected to the AC power adapter, click the “continue” button
3, ongoing battery precision correction, patience wait for, battery status shows “power supply has been switched on, not charging”. When popup “battery precision correction done”, click “confirm” button, the battery status will show “power supply has been switched on, is in charge” which indicates that the battery calibration is successful.

The right way to let the laptop battery charge and discharge

19. June 2013 · Write a comment · Categories: lapton batterier · Tags: Laptop to discharge, notebook batteries

Most laptop users sharing a common experience: laptop batteries in use after a period of time will be aging, charge it into electricity can put electricity. Specific reason is inner resistance, at the time of charging voltage on both ends to rise faster, it’ll be easier to determine by charging control circuit has been filled, capacity and nature is “down”. Because the battery internal resistance is big, battery in use after a period of time will be aging.

Battery charging and discharging:
When the lithium ion battery first rapidly, in the way of constant current charging, the voltage reaches a certain value at constant pressure again after slow charging. Laptop is usually not strict lattice constant current charging monitoring device. System load large charging current is small, conversely is big, the current is determined by the AC power adapter from the power allowance. Obviously, the system will charge when the battery and other parts, such as CPU, hard drives, LCD for the energy. I tried one side run Super PI, charging way, found that changes in between 0.70 ~ 1.70 A charging current can not meet the requirement of the lithium ion battery charge, so I am afraid there will this work when charging the battery is damaged. IBM’s specification requirements for charging laptops don’t operate on might be the reason.

Charging in the boot when charging, if can choose, don’t choose quick charge mode (Express charge mode), avoid premature battery “full”. There is highest when battery power is low to ban the use of CPU performance, in order to reduce competition for power. If laptop computers use the CPU is to support the SpeedStep technology, the best fitted driver (responsible vendor will install) to facilitate regulation performance. SpeedStep program icon is a picture of the blue flag, right click on it can be adjusted to performance options. Under Windows XP, the SpeedStep program will be a problem, this time can only rely on the BIOS parameters or some special brand adjustment procedure, such as IBM laptop tool software function is very strong.

For li-ion battery discharge or has been switched on, make its natural discharge. It is best not to use the method of physical (string, such as a resistor). Not to say that not line, only more dangerous sex, if internal protection circuit doesn’t work, the whole battery is invalid, the worst may be battery burst even explosion, of course, this possibility is very small.
Discharge is as far as possible small current discharge, the operation is to let the CUP fall speed, hard disk first, adjust the screen dark (or closed off), then don’t run any application, until the laptop shut down automatically. Is emphasis on small current discharge in order to prevent laptop early detect the battery voltage is insufficient.

The reason of Laptop battery Battery Life becoming more and more less

18. June 2013 · Write a comment · Categories: lapton batterier · Tags: Laptop battery Battery Life

Laptop are likely to find online friends, many laptop batteries of electricity will use more and more less. Some also specially to the professional information, doubt is quality problem. In fact, appear this kind of problem is normal.
To explain this problem, must from the structure of the battery. Before we understand the basic structure of the battery, laptop battery is composed of batteries and management chip. Batteries, battery storage “warehouse”, management chip computing power and charging and discharging process. Lithium batteries play a role of main element is, this is an active element, in order to ensure safety, can only exist as ionic state in the battery. Lithium-ion battery batteries shape just like batteries, laptop batteries, but do tend to be in groups. We often see the “quad”, “” six core battery is refers to some electricity.
Batteries, means that the capacity is big, high capacity battery cell number is generally at about eight. When it comes to batteries group, leading group of batteries, battery to reduce the “culprit”. Each cell batteries in the group, its quality and discharge level is not the same. After discharge, in order to keep voltage stability, management chip detects that the worst of the batteries for charging protection. This in the past, often the whole battery power will gradually reduce. Appear this kind of phenomenon after can use battery calibration function, this function may be more balanced battery burden “work”.
Here should be mention battery measurement methods, there are four common methods, used several methods but in general are comprehensive, for one of the main calculation method, the auxiliary calculation way to realize power calculation, management.
First is open circuit voltage measurement method, this method is by measuring the voltage of the battery in the stationary state values to calculate the residual capacity of battery, but due to the lithium ion battery still belongs to the nonlinear relationship between voltage and residual capacity, so the measured value of this method is not accurate, the vast majority of mobile phone batteries with this calculation method;
The second call coulometer algorithm, this method is by measuring the battery charging and discharging current, the current value and the time value of the product after integral calculation of battery charged into the electricity and the electricity energy that is released, coulometer algorithm is a more accurate calculation method of the power;
The third kind is the impedance measurement method, it is obtained by measuring cell resistance value of battery remaining capacity;
Fourth is comprehensive look-up table method, by setting a correlation table, the parameters such as voltage, current, temperature input, you can query to get the battery remaining capacity.
But either way, when the charging management chip are following “cask principle”, will be subject to state the worst batteries for protection. So regular cell calibration can to a certain extent, protect battery and extend the life of the battery as a whole.
