1, how to connect your computer to install MP3 Player 2G Memory Silver MP3/WMA Column Shape 

Install the use of MP3 players, under normal circumstances, you must first MP3 player via USB interface with a computer connected to the computer according to the products after identifying the need to install drivers and management procedures. Different products have different requirements, some products need to open the power players can identify others in identifying no need to install the drivers and management procedures on the computer to a removable disk displayed as a direct copy of the audio files to the MP3 player can be used on a specific MP3 player you can refer to the instructions.

If your MP3 player supports removable storage functionality, but has not connected to the system after the discovery of new removable disk, there may be because the system does not assign drive letter, this Windows 2003 system in the most common . You can "control panel" on access "management tool", select "Computer Management" in the "Computer Management" window on the left select "Disk Management", if the right side of the window, MP3 players, the system can be listed, then the You simply use the MP3 player right-click the device icon and select "Change Drive Letter and Paths." In the pop-up window, then click the "Add" from the "Add drive letter or path" dialog box drop-down menu for the MP3 player to select a drive letter (Figure 1), in recognition memory and exit the "Computer Management" window after the , you will be able to discover new removable disk have emerged.

The basic working principle of the computer keyboard, the keyboard's function is to discover the key is pressed, and the key information into the computer. There are buttons under the keyboard found in the location of key scan circuit, it is being pressed key code encoding circuit, will generate the code into the computer interface circuit, these circuits collectively referred to as the keyboard control circuit. Based on the keyboard works, computer keyboard can be encoded into the keyboard and non-coding keyboard Dell inspiron 9300 Keyboard  Dell inspiron 6400 keyboard

Dell inspiron E1505 keyboard: the keyboard control circuit functions entirely on the hardware auto-complete, this keyboard is called encoding keyboard, it will automatically press the key code information into the computer . Encoding the keyboard response speed, but its structure in complex hardware cost and its complexity as the key function of increases. Another keyboard, it features keyboard control circuit to rely on a common hardware and software to complete, this keyboard is called non-coding keyboard. This keyboard, the keyboard response speed faster than coding, but it is available through software for some of the key to redefine the keyboard, in order to expand the keyboard feature provides great convenience, therefore, is widely used. Non-coding keyboard works as follows: the keyboard and coding is different from the non-coding keyboard does not directly provide the encoding key information, but with relatively simple hardware and a set of specific procedures to identify the key position. Non-coding keyboard, by software, hardware, with the completion of the keyboard work

Notebook computer lithium-ion Apple A1078 Battery Apple A1079 Battery    HP pavilion DV6000 Battery in the proper charge [Author: Anonymous | Time :2009-7-7 | Views: 249 | Add to Favorites] ¡¾Big Middle Small¡¿ some equipped with lithium-ion laptop batteries, using the wisdom of the battery such as the SBS system technology to accurately measure battery life, so use this to worry some. Although the lithium-ion battery has many advantages, but to extend battery life and maintain long time power supply, but also need to master some professional charge method.



The new lithium-ion batteries bought in the initial use will be conducted three times a full charge and discharge, that is, fully charged battery at least once a power, then power exhausted, repeated three times before use. In order to activate the chemicals inside the battery, so that the electrochemical reaction inside the battery into the best condition, in the future be able to freely use the charge that is useful, but to ensure that within one month, the battery must be a complete discharge, so that the depth of discharge can stimulate the activation of the battery performance, battery life plays a key role. If more than 3 months the battery is not used again before using the same should also be carried out with the new battery charge and discharge completely three times to ensure that activate the battery.



If you use nickel-metal hydride batteries, which must control the charge time, should be careful not to frequent over-charging, otherwise it will shorten the battery life. In addition, the Ni-MH battery should be fully discharged before charging, the charging should also be fully charged, and in normal use before, but also required to complete three complete charge and discharge times.

The development of computer technology can be said that the rapid, but the keyboard always been the most important computer input devices, although its price in the computer configuration, a small proportion, but because of its high frequency of use, so the keyboard still has not shaken the status of the computer system needed to start testing the keyboard, set the CMOS when they need to use the keyboard, write a document or e-mail when they can not do without the keyboard. As an important input devices, keyboard by virtue of novelty, utility, comfort, constantly strengthen its input device, the first position. If you want to use the keyboard even easier, you should know some of the maintenance and repair knowledge, the following will do for everyone to introduce:
    1, the keyboard Dell latitude D520 Keyboard Acer Aspire 3000 Keyboard Acer travelmate 2300 Keyboard routine maintenance

On the proper use and maintenance of the keyboard, the computer work is very important, and its routine maintenance, mainly from the following aspects:

1. Keyboard is configured according to the system design requirements, but also by the system software support and management, and replacement of the keyboard to shut down the computer power in the circumstances.

2. Capacitive keyboard because of its special structure, easy self-test occurs when the computer boot normally, but its vertical, horizontal multiple keys at the same time does not work, or partial failure of multiple keys at the same time failure. At this point, should open the keyboard case, carefully observe whether the failure of keys in the same row (or column) circuit. If so, and the printed circuit nor broken, it is to connect the metal lines due to poor contact. Disassemble the keyboard in-circuit board and film-based movies, so the connection between the two lines of metal printing wipe, after which the two match well, bottles and layering, can be pressed.

Among the many places in computer accessories, keyboards, though hardly a noble, but it is in our work in the role they played a crucial way. For the master, we have reason to believe that in the absence of a mouse in which case he is also the normal operation of computers; However, if someone says he can not have the keyboard will be able to skillfully manage PC, it can only be "unbelievable" to describe.

The keyboard to the importance of self-evident, but perhaps because of its price to factors, many of the computer keyboard, friends encounter a failure will be readily discarded and re-buy one, do not study how to repair.

The writer a few years experience in computer maintenance, in fact, sometimes the keyboard is not the normal operation of the keyboard can not be completely damaged, but because of some small way things are at play, as long as you have some troubleshooting tips to small, then you will definitely be in the keyboard once again its youthful to appeal. Here I talk with everyone together how to handle a keyboard failure.

Principle of the keyboard 

Dell Latitude E5500 Keyboard  Dell Latitude E6500 Keyboard  Dell Latitude E6400 Keyboard to work

Entering the text, we first take a brief look at the keyboard working principle, so that it can help to deepen understanding of DIYER. Keyboard is the most commonly used in computer input devices, which generally keys, conductive plastics, as well as the encoder interface circuits so on.

On the keyboard usually has hundreds of buttons, each button is responsible for a function, when the user presses one, the keyboard encoder to quickly encode this button corresponding to transport through the interface circuit to the computer to the keyboard buffer in the by the CPU for recognition processing. In layman's terms that is, when the user presses a button, it will be through the conductive plastic circuit board in this key cable connected to generate signals to the signal generated by the keyboard interface will quickly be sent to CPU.

Some of us have the whole keyboard, a computer may be the most expensive components, but this does not mean that there is no keyboard, a careful maintenance of the value. A keyboard, if used properly, maintained better, can use a few years, on the contrary some of them even have not take a month. Talking about the use and maintenance of the keyboard, not a particularly complex process, just that we pay attention to the use of the process, you can play a very good results.

Upstream refers to the keyboard at a good like flying is indeed a pleasure to use the keyboard as long as there will be wear and tear, will feel a recession as part of aging, how to slow down the aging speed of the keyboard becomes a problem.



On a regular basis to clean up the keyboard

Typically, the keyboard is very easy for maintenance without feeling down, for the excellent quality of the keyboard for such a problem largely caused by debris within the keyboard, many people have in front of the computer eating and smoking habits, debris hinder the trip button, but also increase the wear buttons, but the tar in cigarette smoke is the enemy of the keyboard.

Laptop power adapter Dell inspiron 1300 Adapter Dell PA-6 adapter Dell PA-9 adapter is a high-precision, high-efficiency switching-type regulated power supply, its role is to 220V of AC electricity is converted to low-voltage DC, for notebook computers to work to provide a stable power, it has even been referred to as notebook computer's "power source." Due to the internal power adapter is a work in the high-voltage, high current state of the switching power supply, work load is fairly prevalent, and is completely closed structure, there is no cooling holes on the shell, the internal nor the fan-assisted cooling, and thus power adapter at work, the internal temperature is high. Especially in the hot summer, touching the surface can feel the hot, the internal temperature is even higher. And thus in their daily work and entertainment, make it proper maintenance and maintenance. 1. To create a good thermal environment in high temperature environment, using a laptop computer, power adapter should be placed from direct sunlight and well-ventilated places; not to the power adapter on the notebook computer cooling air outlet nozzles near the Otherwise, not only the power adapter is not out of the heat distribution, but also absorb some heat. During the hot summer, we can put adapter side in order to increase the contact area with air adapter, so that the adapter to better distribute the heat out. In order to obtain a better cooling effect, we can also pad between the adapter and the desktop into a narrow plastic block or piece of metal, in order to increase the air convection around the adapter, speed, speed up the adapter's heat. 2. An exception occurs in time to stop using the power adapter to issue a larger noise or smoke when working, often damaged or have problems should immediately stop using, by the professional engineer by the repair before it can once again put into use. 3. A reasonable charge when the notebook computer's battery is in charge state, it is best not to run major 3D games and other machine so that the heavier the workload process, lest the power adapter output power due to lack of surplus capacity which led to slow down battery or charge dissatisfaction, power adapter,

Battery hazards: a discarded mercury Apple A1078 Battery Apple A1079 Battery    HP pavilion DV6000 Battery in nature will slowly overflow from the battery into the soil or water, and then enter the body through the crops, damage people's kidneys. Under the action of microorganisms, inorganic mercury can be transformed into methylmercury, gathered in the fish's body, the human consumption of this fish, the methylmercury enters the human brain cells, people's nervous systems were severely damaged, re - who would be crazy to death. Well-known Minamata disease in Japan is caused by methylmercury. Cadmium exudative contaminated land and water bodies, and eventually enter the human body makes the liver and kidney damage, can also cause bone soft, heavy causing skeletal deformities. Automotive Waste batteries contain acids and heavy metals leaking into the nature of lead can cause soil and water pollution, and ultimately harm people.

Recycling of waste batteries: the popularity and variety of home appliances increased, resulting sharp increase in the use of the battery. Waste batteries mixed with garbage, not only pollute the environment, but also a waste. National annual consumption of the battery 30 million, were lost due to non-recovery of 740 tons of copper, zinc and 16,000 tons, 97,000 tons of manganese powder. We should be separated from waste batteries and other trash, together sent to recycling. Many countries attach great importance to the recycling of waste batteries. Germany's many shops asking customers to buy the battery at the same time used batteries should be returned to the store; Japanese exclusive collection of different bins of waste batteries.

To understand these concepts, we can determine the second question of this article. The same nominal power HP 325112-001 Adapter  DELL inspiron 1000 Adapter

Acer PA-1650-02 Adapter supply voltage, output current is different, the same can be used in the books. The underlying principle is the nominal current of large power can be replaced by a small nominal current of the power. Some of our friends there was any misunderstanding, I feel great nominal current of the power will burn books, because the current big Well. How much current is actually the same situation in the voltage depends on the load, that is, the work of books, when the books when the high load operation, the current was much bigger when the books go into standby, the current on the smaller, short current equal to added to the books the voltage divided by the books on the equivalent resistance. Large nominal current power supply has sufficient current margin and will not replace the current power after a small nominal output voltage is too low or overheating situation. On the contrary, with a small current is replaced by high-current power supply on the existence of such a risk. But some friends instead of 72w with a 56w power supply is also no problem with them, because the power adapter is usually designed to leave a margin, load power must be less than the power supply power, so this place is in general use feasible, but the margin on the remaining Power are few, and the books once you pick a lot of peripherals, such as the two usb hard drive, and then cpu running at full speed, and then there is a base with a drive at full speed to read the disk, and then with the same time charging the battery, estimated to be dangerous, it is necessary to keep your hands touch the power supply is not already a boiled egg. 72w more than the 16w adapter, 56w is the deal with this situation. So it is best not to use the small high-current power instead of high-current power supply. If you really do, conditional friends can try to Cece largest consumer of your books, when the actual needs of current measurement method is simple, a socket, a plug, an ammeter, Jigen wire, a soldering iron can be. If you have the power within the nominal current, of course, is safe.
