Vices 1: Repeated Turn off the machine

 

Repeatedly switching the machine that has found this issue may occur if it is to understand computers, or do not include shrimp computer rookie, are likely to grow without knowing a bad habit. In fact, the computer startup and shutdown IBM ThinkPad R51 battery will not cause damage, but the time interval between the two is very worthy of our attention.

 

Frequent, short shock pulse voltage may damage the integrated circuits of your computer, secondly, the greater harm is the hard drive, hard drives are now high-speed hard drives, cut power to the disk complete cessation of rotation, requires a long time. If the drive does not stop change on re-boot, which is equivalent to the hard drive in a slow state of re-acceleration. If this continues, the impact of this will make your hard drive saved my life one day. With the development of technology, the stability mark the desktop has reached a very high level, so now the brand will be put up very little chassis RESET button, which suggests that if we plant the machine is the situation then we can forcibly shut down, therefore more likely to cause damage to Dell Inspiron 1300 battery the hard drive, so we must pay attention that we usually pass the operation of machinery, protect our computer.

 

Vices 2: never clean hard drive

 

To maintain the drive for order and cleanliness are our most basic steps of the computer. Drive long-term use is required to have accumulated a number of junk files and disk fragmentation, will organize the hard disk of debris on a regular basis, will be conducive to the release of hard disk space.

 

There are many users will not notice the hard drive order, because for the BATCL50L obvious things on the desktop and everyone can see too, but for those who can not see the debris and often do not this awareness.

 

Vices 3: Direct delete the folder

 

After installing the software, we usually have an installation directory for the installation files are in this case is basically the reason the word “primarily” in, because when the software or the game after installation The file will always be part of the information is stored in the system tray, if it is carried directly into the folder to delete, then let the hp PP2182L battery system tray of junk files piled up. Never delete the file directly

 

The system is generally provided to add and remove hardware function, use this function to delete the software is the most thorough.

 

Vices 4: Installing things by default for the system drive C

 

During operation of the computer, when the most basic courses, software installation, if you tell me not to install the software, then I collapsed. If you tell me it’s very simple, just select Next and then conducted a Gaoding, then congratulations, system tray will be filled in the near future, the system will be very slow, and there may be a complete collapse.

 

Generally, whether to download the software or develop their own CD-ROM drive for installation, the system will be installed by default in the C drive is the drive system, lack of disk system will lead to many problems, I once encountered a similar problem. A friend’s computer can not enter the system, and I’m finally end in the other system software, was surprised to see the C drive only a few megabytes of space, so I really afraid of people, they also advise everyone to install the software when the ordinary to have a good habit.

 

Vices 5: over-charging Laptop battery

 

Historically, outbreaks of lithium batteries portable occur frequently, but also no shortage of managers, the branded products. These events in the industry are also swirling speculation. Many airlines have imposed a ban on carrying a laptop with the apple M8403 battery from the aircraft. For a while, the battery has become hateful to everyone across the street rat. In addition to the quality of the battery itself, in fact, the use of man-made habits is also very important.

 

We all know that the battery is a consumable, a range of 1-3 years in general, of course, good, there are also over time, while the battery life and is closely linked to the habitual use . There are many users often use the laptop when the battery has been installed on the laptop, almost never disconnected, so that a decision appears to avoid complications, but it ruined the sony VGP-BPS5 battery life of several months or more. Now the notebook world outside surface except a few, most laptop batteries do not have adequate protection measures, Chong Man-power battery after recharging the battery will always l ‘State, so that the battery life is dependent on several occasions a sharp decline, severe may be due to overheating of the battery and burning.

Why the battery life be shortened?

Digital battery / No Comments

The battery of multi-buyers wondered why the battery of my old? After reading the contents of one would understand that we must understand why the capacity of the battery down? “The reasons for the decline in capacity, and why?” “The battery internal resistance will affect the capacity?” We then explain in details.

 

Laptop battery capacity after repeated loading secondary discharge will decline, its causes are complex and diverse, not only after repeated accusation, the discharge capacity will decrease, even long not to use, have the same problem of declining hardware capacity, rather than the charge and repeated the battery is discharged more easily damaged, because the battery is the use of chemicals from the chemical energy into electrical energy products, chemicals to maintain their regular activity and only less than a deterioration of failure, when the original activity of two compounds role of the end or nearly out of season, and will not be able to perform chemical reactions, this time the decrease battery capacity, that is, the cells are already gone, the battery must declare died.

 

Volume decline over time tends to happen when?

 

A good quality of the secondary battery, the continuous load and discharge over 500 times the capacity can reach over 70% even higher, but the decay rate of the IBM FRU 92P1141 battery capacity, plus good or bad depends on the battery cell, based on the battery yet to match the user the use, storage, temperature, remarkable degrees to prolong battery life.

Indeed, although marked as secondary batteries can be reused, but he still has his life there, so laptop battery, for example, the ability to label 4000MAH, but after the charge and discharge its capacity will be successively reduced by one year after the building are more likely to fall into the 3300mAh below, it is a normal phenomenon of secondary batteries, but can also see this problem is actually continues until that the battery technology, the use of both the meaning of love using a usually short period of time, and when using the battery Time is Running Free When this time to replace the battery.

 

What is a voltage difference?

 

Many Li-degradation capacity of ion Dell U4873 battery or failure due to a series within the battery due to voltage difference generated, resulting in cell battery produced the gap between tension can be avoided, because each battery string of battery cells nature can not be exactly the same, with a long time, there are some features of the natural and poor battery before aging, affecting the curve general discharge. It is with gratitude that the aging cell batteries have been the first full charge and discharge has also finished first place, but this time the ability of cells to the other battery is not fully utilized exhausted.

For example: load, others charge the battery kernel boot approaching saturation when the voltage is 4.2 V, while the aging of the battery cell may have been grateful to 4.3 V or a voltage even higher, causing an overload of electrical cords and other costs dissatisfied; discharge, when the strings are always large voltage range of work that is already grateful old battery or battery is already below the normal operating voltage , 3.0V, resulting in a unique string of low voltage protection, forming the hp PP2182D battery to discharge faster.

 

What is battery aging?

 

The aging self-styled drums, which, as the increased frequency of use and time, or long-term investment, leading to the capacity of the storage battery, the progressive deterioration, when battery is only one, the batteries, they will build the capacity reduction, while the group of battery Multi-core set-batteries in parallel, they generate all the associated voltage difference, this time the user is most likely aware, the battery is also clearly shown that over 50%, how suddenly dropped below 10%, and even non – normal shutdown, resulting from the use of time, simply said: aging the battery is a decrease in battery capacity .

 

Aging of the battery cell internal battery do what needs to be changed?

 

The aging batteries, the most frequently observed is the easiest to detect is the change in resistance, the internal resistance of the sony VGP-BPS2 battery when the nucleus is very small factory, but the charge and discharge over a long period, because of electrolyte in the battery, and a swimming pool in electronic activity of chemicals in the lower internal resistance of the whole because of increased electrolyte will gradually repeated load variability of discharge, the resistance will continue increase until the resistance as large as the power of the internal battery is not properly released, a common phenomenon is the mouth of the battery, this time, the battery is the so-called aging and capacity battery will decrease with respect, most of the aging of the battery is because the resistance has been caused in the cause can not be used.

 

Change of battery internal resistance include the following:

 

Changes in the cathode materials

 

The molecular structure of the battery, the positive and negative electrodes can hold rainfall on the hole structure of chemical molecules will gradually with the number of loading and unloading of collapse. Blocking, which is positive and negative active materials, passive, there may even be negative materials are polarized phenomenon, reduces the toshiba PA3383U-1BRS battery charge-discharge process can be free to move the number of ions.

Catalyst for Change

 

A catalytic role in the molecular structure of the catalyst, due to temperature, humidity, storage time, gradually changing its structure and nature of the final can not be catalytic.

 

Electrolyte metamorphic

 

Electrolyte because of the battery after charging and discharging several times, but it was bad, and even the loss, the low quality of basic battery is easier because the composition of the electrolyte under the control of undesirable while the faster deterioration.

 

Conclusion:

 

Again, the apple A1185 battery itself as a kind of oral consumption, with the increase in the number used in the battery charge storage capacity, the successive reduction of life cycle support of about 500 times more than the estimates of the time, if the first few days of use, between about 1-2 years we should move to a new battery a.

But for the laptop. The battery is expensive consumables, many people would say that I try to use less battery, or simply do not need batteries, so there is no life cycle of battery problem, but in fact, a This concept is not always the case is correct, the number of batteries affect the battery life conditions, but not the key, because, as mentioned in this article, the battery’s chemical energy of products will evolve with the passage of time, but to reduce its activity, stood not the same because of self-discharge and lead to an excessive discharge, and loss of activity and damage to the canal, so carefully When you pay attention to your battery at the same time, remember the proper use of batteries, but also the Aspire 3000 battery charge and discharge on a regular basis, so your battery to play a greater efficiency.

The knowledge of laptop batteries DIY and Maintenance

Digital battery / No Comments

Some people, against the battery of the laptop is the blood of the body, although not very precise, but the resulting battery cell can still see the importance of a laptop.

 

I bought second hand laptops have been for some time. When I started with the Laptop battery to supply a laptop for membership to 50 minutes before the time less and less, until eventually work more than 10 minutes. Although couples battery laptop second hand is unrealistic, too (as long as several minutes can be used to prevent a power failure may be caused by data loss), generally used as a UPS. But in fact I am always behind his back, often in places where there is no outlet to use it, so always expect the battery will work as long as possible because it can greatly improve the mobility of laptops.

 

Spent much energy on the market to find, but always the first wife did not find the battery. Relied on their own notebook batteries have a certain understanding, and repair of certain powers of the device, try to repair itself. The next operation, tools required are: multimeter, soldering iron, pliers, razor blades, pliers electrical tape, wire or a small bulb.

 

Capacity Restoration Act

 

Remove the IBM ThinkPad R40 battery from the laptop and discovered that the battery box labeled “Ni-Cd”, “9.6 V 2000mA” the words, indicating that the battery is a nickel-cadmium batteries (rechargeable batteries are worst case), rated voltage of 9.6V, 2000mAh capacity. A total of eight batteries metal interfaces, respectively, from left to right mark (the battery with the label side up) – TTI + I +.

 

Measured with the multimeter found that the battery has two batteries, the leftmost “-” and the right of the second “+” is a group, the second left “-” and the far right of the “+” is a group. Detection of two batteries are really for no-load voltage of 9.8V, and when the battery is low voltage alarm, after the mobile starts (and one might expect that there should not be too many ‘ electricity)! Concludes: the laptop to start with low voltage alarm goes off automatically after a while, but when the battery is not fully satisfied, it is a certain degree of residual power, while nickel batteries cadmium have memory effect and do not take full charge over time will reduce Dell GD761 battery capacity.

 

Then sent for two son of heating (which can also change a light bulb or power resistor) connected to each positive battery cell and negative ends (the discharge current can be controlled to 200mA ~ 500mA between the specific capacity the battery must be considered, while all – usually 0.2C ~ 0.5C is the battery nominal capacity of 0.2 to 0.5 magnification of the discharge current), to release the battery power of finished products base and then it stalls multimeter electrical current to 10A and finally exhausted the battery back in the laptop for a normal load. After such repeated four times and found that the hp PB995A battery was able to work more than 40 minutes from time, primarily to meet the requirements of use.

 

If your laptop battery is a similar situation, according to the above method a try, there may be unexpected pick up! In addition, if your laptop uses a lithium battery, the discharge of the battery cell in a note to be sure to jump the battery box of the circuit, because the only way to achieve good results.

 

Cell replacement laptop battery

 

With the method of recovery capabilities can be used to extend the sony VGP-BPS2A battery for some time to solve the problem, in addition to replacing the entire stack outside the (laptop batteries second hand is very difficult to find same model) can also change the core of the battery. But it also requires a better understanding of the knowledge of the battery, which powers the operation stronger. What follows is still my laptop batteries, for example (models of laptop is Fujitsu’s FMV-575NU / Y), introduced the replacement battery cell.

 

Although laptop batteries at the same time, there are two sets of batteries to power the machine, but with the test film multimeter Store Laptop batteries touching the spring, found the battery marked “+” or “-” the metal two springs in contact touch pads are interdependent, which means that the battery is actually two machines in parallel to food.

 

Battery with a blade along the slits on the sides of the battery carefully cut and found the battery box, a total of 16 monomers, which can be translated outside of a cell voltage and capacity, respectively: 1, 2 V, 1000mA. Although its shape and size and the general on the 5th, as the nickel cadmium batteries, but with the toshiba PA3465U-1BRS battery capacity on the market can not find. Finally, a store second-hand computer to find a Fujitsu FMV-575NS / batteries for laptops L, the label can be seen from the shell of the battery is Li-ion battery (Li-ion), tension 10.8V, capacity is 2400mA. And the battery on my laptop while Fujitsu, but the voltage, capacity and batteries are some differences in their nature, can replace the heart was not in the end, but still spent 180 yuan bought.

 

Home to the lithium battery open, rounding the circuit inside, remove the battery 6 monomer, a single cell parameters are: 3.6V, 1200 mA), according to the original arrangement of the circuit to the battery 22 in parallel and then series, using duct tape for six cells connected in a series of warehouses and under the battery of the laptop. Some laptop batteries in both positions with the “+” connected to a spring to choose the film touches arbitrary use with the battery cable connected to the positive terminal, so choose one with the “-” connected to the touch compressed spring and the battery connected to the anode. Finally, we need the original laptop batteries due to both labeled “T” word for the metal interface of an electronic component (this component is estimated laptop in the identification circuit of the battery to detect whether battery connected to the notebook) were removed, the welding position corresponding to the touch laptop spring on chip (if not this component, use the apple iBook G4 14 inch battery to the laptop power supply, the Power On Self Test appears after a while, the machine automatically shut off phenomenon). Of course, these operations must be conducted in the shutdown state.

 

As for the use of force after the reform, we should say is rather satisfactory: I just bought a laptop battery works more than 50 minutes, and disposal after use change of such methods, we found that the batteries of laptop computers can escape through the 2 hours continuous operation experimental 40 minutes, I was very surprised. Although this example is in my laptop Fujitsu’s experience from the successful experience of the current situation, but we can understand by analogy. It should be noted that the restructuring should take into account several key factors are: Battery voltage, nominal capacity and volume. A little different voltage and rated capacity, not a big problem, but if the TravelMate 290 battery after the reform are too large will not fit into the warehouse of the original battery, no matter how long laptop battery are not really meaningful (and you still can not laptop batteries outside, pulling a long wire with Jigen bar – if so, the portability of laptops is significantly reduced in!)

 

Ultimately remains to remind you that this method has great risks, for reference, there is no certainty do not apply. Otherwise, in the process of restructuring and unexpectedly, and my education “Chinese computer” are not responsible.

 

Editor’s Note: This article is mentioned in several respects, indeed, applied to a number of occasions, such as maintenance of mobile phone battery. In addition, the movements of exchange battery, as this author can buy the same second-brand laptop battery hand and get used the example of lithium batteries can be described as lucky. Lithium batteries performance is good, but can not make this event, readers can use in practice, instead of nickel-hydride batteries in metal. Currently, there are many sales in the electronics market nickel-hydride batteries, metal, we can buy as needed. Add that use nickel-hydride batteries in metal have several advantages: first, cheap, easy to access; Secondly, the nickel-metal hydride batteries are not “smart” lithium have not need more of the auxiliary circuit and turn it more convenient Completed batteries for laptop computer use in place a more secure world: the three, only the voltage nickel-metal hydride batteries to 1.2V, 3.6 cons V Li-Ion batteries need to be more easily combined into a voltage. Of course, gaps nickel-hydride batteries in metal are also very obvious, the weight of the component, a relatively low capacity of Dell U4873 battery the main problem.
