How to care and protect a computer, the maximum extension of its service life, is we are very concerned about the topic.Laptop ac adapter AC adapter

Routine maintenance can not relax

Life of the computer environment can not be ignored. PC is the ideal working temperature 10 ℃ -30 ℃, too high or too low will affect the life of computer accessories. The relative humidity is 30% -80% too high will affect the CPU, graphics and other performance parts to play, and even cause some parts of the circuit;

Too easy to produce static electricity, the same disadvantage of the use of accessories. In addition, the air of dust content on the computer as well. Too much dust, corrosion will be the constant, daily accessories, chips, circuit boards; content is too small, will produce a static reaction. Therefore, the computer room is best to keep clean and tidy.

Some people think that a small number of computers or use a short time, you can extend the life of the computer, which is one-sided and ambiguous point of view; the contrary, no computer for a long time, due to moisture or dust, perspiration and other factors, may cause damage to computer accessories. Of course, if the weather is wet to a certain extent, such as: laptop keyboard lcd screen

Display or chassis surface moisture, drying time must not give the machine is not powered, so as to avoid unnecessary losses caused by short circuit.

Good personal habits a great impact on the computer. So let us carry on and off the right order. Boot order is: first, peripherals (such as printers, scanners, UPS power supply, Modem, etc.), monitor power is not connected with the host, but also the first turn on the monitor power off and then open the host; off the opposite order: first off the host , then close the peripherals. The reason is that as much as possible to reduce the damage to the host. Because the host power, close the peripheral of the moment, will have a strong impact on the current host. Off after a period of time, not frequently open, shut down, because a big impact on all parts, especially the more serious damage to the hard drive. The next general shutdown from the start time should be at least 10 seconds. Special attention when the computer work, shut down operations should be avoided. Such as: reading and writing data, the computer is suddenly shut down, it could damage the drive (hard disk, floppy, etc.); also can laptop battery Acer AC Adapters  not move the machine when the machine work. Shutdown, should pay attention to first leave the Windows operating system, close all programs, then exit the normal shutdown sequence, or may damage the application. Of course, even if the machine does not work, they should try to avoid moving the computer, because excessive vibration on the hard drive, motherboard components like damage.

We know that mobile phone battery is a source of electrical energy, which is the phone's power, not battery powered, mobile phone is a piece of compaq AC Adapters dell AC Adapters hp AC Adapters toshiba AC Adapters  scrap iron, a high-capacity high-performance batteries, not only to the cell phone long battery life, but also to protect phone circuit, making phone is able to work efficiently for a long time, otherwise it is likely to cause unexpected damage to the phone. For us players, the performance of the battery when the factory, it had already been determined, the size of its power, performance, good or bad, are determined by the battery itself, and in this respect we can not change people, but This is not to say that we get the battery to it that can not do. Phone use are lithium-ion rechargeable battery, the use of the electricity used in storage, need to be added once the power charge. Do not underestimate this part of charging, a good battery charger and charge the right way to keep the battery long standby time, but also extend battery life. Further step that the phone can also play a protective role. Methods on how to charge, often there will be players in the forum asked, after a period of time to own the actual use and reference, I summarize the following points:

Currently, the rechargeable lithium battery technologies for your Apple notebook computer, iPod or iPhone showed the best performance to provide protection. You can also find in many other devices such standard cell technology. Apple uses lithium battery technology and other equipment have common characteristics. The batteries and other rechargeable batteries, eventually to be replaced.ASUS Eee PC Battery Sony VGP-BPS8 Battery
Industry-standard technology

Lithium-ion polymer battery than the nickel batteries with higher power density. Because lithium is the lightest metal, so the device lighter and longer life expectancy. You can at any time for lithium-ion polymer battery, but did not like the nickel batteries, to ensure the best performance, each of which must be fully charged and discharged. (As time goes on, will appear within the crystal of nickel batteries, to stop you a full charge, resulting in the situation can not be fully discharged.)
lithium-ion Battery Charge Chart


Standard Charge

Most lithium-ion polymer batteries are used a fast charge mode, your device can be quickly filled with 80% of the electricity, and then converted to a trickle charging mode to continue charging. If you do not use while charging, about two hours to 80% for the iPod is full of power, and then two hours to be completely filled. Can be repeated for all rechargeable lithium-ion battery, but a limited number of charge cycles, depending on the charge cycle may be.
Charge cyclesAcer Aspire 1680 Series AC Adapter   Acer Aspire 3000 AC Adapter   Acer Aspire 3500 Series AC Adapter 

Charge cycle. The battery is empty, then filled with a full charge cycle.

A battery charge cycle means that all the electricity used, but not equivalent to one charge. For example, you can listen to iPod a day for several hours, only half of the electricity, then it is fully charged. If you are still so the next day, this can only be counted as one charge cycle, not two, so you may take several days to complete a cycle. Each complete a charge cycle, battery capacity will be reduced a bit, even so, replace the batteries in the past, you can still give laptop computers, iPod and iPhone battery charging many cycles.
The most effective use of power

Your battery to maintain the length of time depends on the equipment you use. For example, watch the DVD than the simple word-processing power much faster. You can follow some very simple steps, the most efficient use of laptop computers, iPod, iPhone or iPad's battery life.

Battery means that your Apple notebook computer, iPod or iPhone's battery must be charged before use of time (sometimes also called "active time" or "run time").

Battery Life The battery had to be replaced before the end of all life.

Although many people will choose to purchase laptop computers as the first choice, but because of the many Middle School students are busy learning, usually on the laptop is not very understanding, so said the store did not know their own minds will be very easy to be some ulterior motives JS deceived, resulting in unnecessary loss of support here, I'll give you the recipe, but we recommend to all ten are more suitable for third year students choose a notebook, laptop if you intend to buy the near future, it may wish to send this article Read it again.

Step one: select models, the first thing to do before buying notebook is selected models they need, notebooks are consumables, although the notebook performance is more difficult, but who also allowed three years after Paul mainstream configuration will be stronger than it is now on the number of notebook performance, so when buying notebook to choose according to their needs, not too far in pursuing the strong performance of the model, if you usually just use the laptop to see some movies, browsing the web, that the mainstream price points Laptop fully able to meet your needs. If you usually are used to process video, audio, pictures are more powerful then choose a notebook processor. Word: that is best suited to their own.
