Into the winter, most areas have become very low temperatures in some areas, temperatures can reach below zero, cold environments this laptop is a lot to say that if not careful, you will find that sometimes fragile laptop. The following, I'll talk about some of the winter use of laptop computers Note:

Reduce outdoor use

Most notebook computers are designed for civil, does not have a higher resistance to low temperature properties, and its LCD screen is usually designed to work in the 50 ℃ ~ 0 ℃. If the outdoor temperature exceeds the design work, will result in:

1, reduce the life of the LCD screen;
2, the LCD screen freezing, laptop computers stop working.

Most notebook computers use lithium-ion battery, this battery with the power of minus 20 ℃, with a charge will be reduced to 80% of normal, which will result in:

power adapter and battery

Wide variety of laptop power adapter can ACAdapter (variable AC to DC) and battery power. As a result of the power adapter has its own input / output voltage and rated power, therefore, best not to pay attention to the different models are equipped with laptop power adapter mix, so as not to burn out the machine. In addition, in the purchase after long hours of liteon PA-1600-05 Adapter dell PA-1900-02D Adapter
work should pay attention to the temperature of the power adapter how, not too normal. Batteries are currently used by Lion and Ni MH battery two. Lion battery is currently the mainstream, usually smart battery, with memory function, and the lighter, use the time normally longer, prices are more expensive; and Ni MH batteries are generally heavier weight, and may often need to learn the battery , wash it in the memory, but the price is relatively low. Current battery time is generally about 2 to 3 hours, if need a long time continuously (as frequently engaged in outdoor activities or travel of personnel), you can choose to use a longer time and have power to set the battery (Suspend) machine, or for a second backup battery.

4, hard disk capacity

Hard disk capacity is currently increasing, the current mainstream is about 250GB. In addition to capacity, but also consider the disk thickness, speed, impatient tone, the average seek time, if the parameters of power and so on.

5, CDROM and DVD

The current drive is divided into two CDROM and DVD. CD-ROM has become increasingly important, often the machine is equipped with a CDROM drive, the machine should pay attention to the election, read the disk drive stability, the voice to read the disk, read the disk when the error correction capability, drive speed. In addition, the current high-end machines have been equipped with a DVD, while equipped with the appropriate DVD, play a DVD in order to better advantage. DVD drive is compatible with the CDROM disc. High-end machines such as the violet Prophet series of notebook computers are currently equipped with a DVD drive. DVD is the future trend of development, but the price is more expensive, not popular in the current DVD discs, when, 24xCDROM sufficient to meet the general needs.

6, multimedia applications

Notebook on the market today most have some multimedia features such as soft extract, MPEG card, sound card, video card, speakers, and some have even equipped with a DVD. Should pay attention to whether the machine has audio input / output ports, MIC interface.

7, Allinone design

Refers to whether light notebook computer, integrated into the machine with the floppy inside. Generally speaking, if for the whole internal structure, is more convenient to use, but may also make the weight, size, price too high; and if light, external floppy drive, it would make the machine weight, volume, including the price more down easily, but it may also enable users to use somewhat inconvenient.

In order to obtain a good brand of social reputation, the general in the production of computer components for the various quality requirements are very strict, they have fixed partners, parts of the source fixed, thus avoiding all kinds of fake, defective appearance. However, "It is said that" now there are some vendors in order to profits, there will be some good red seq phenomenon.

And the more easily compatible in the selection, the general idea of ​​random configuration by the user, but also in the process of buying the source of volatile components, so that there can not avoid the quality problems, but if the hardware has a certain ability to identify, in the selection process Be careful, this situation can be avoided.

2, production

Brand of machine in the production process, strict testing by experts, commissioning and long baking machine, so to avoid compatibility problems the machine, the user after the process due to the use of compatibility problems will be less.

Compatible in accordance with the wishes of the user to assemble temporary, though sometimes a certain test, but after all, no professional skills and testing tools, and baking machine time is limited, the probability of future problems certainly higher than the brand of machine.

3, the price

The important point is to buy a computer prices, because the brand of the production, marketing, advertising can not avoid to spend a lot of money, so its price must be higher than the price of compatible computers.

Less compatible because all the above expenses, the price can imagine.

4, after-sales service

Brand machine to increase sales and visibility, have their own sales channels and good after-sales service channels, so that the user would quickly when problems arise after the given solution.

Purchases channel is not fixed as compatible, if in some small companies to buy, over a period of corporate failure, and that service on where to find it.

5, the upgrade

Card machines due to consider the stability of the general configuration of its fixed, and some even allow users to tamper with the recent launch of major companies in the low-end machines, most have adopted the integrated motherboard, which the user after the upgrade is for the negative .

I always do not understand, what the computer is fake in the end, where he was off in the end, is not difficult to distinguish between true and false, but after many years of experience, I think that is nothing more than the so-called fake and other commodities, have polished , forgery, shoddy few in species, and as long as careful observation, a lot of comparison, note that summary, use of testing tools and other means, are generally able to distinguish between true and false parts.

1, motherboard, sound card, video card

Generally speaking, the so-called fake, some unscrupulous manufacturers of motherboards red seq good, real ones, the poor say that good. The formal motherboard manufacturers have some important features, as long as we grasp these features, the motherboard is not difficult to distinguish between true and false, the formal number of motherboard manufacturers have such features: a, very particular about the materials used in various parts of b, the circuit design aspects of using "S-type routing method" c, the motherboard work fine, smooth solder joints, a variety of ports and sockets without any loose d, a beautiful packaging, the box should have the motherboard manual and some necessary connection Many programs also comes with a floppy disk. These characteristics in accordance with the above, identify the time of purchase as long as serious, is not difficult to distinguish between true and false. (Sound card, video card may refer to the motherboard)

2, CPU

CPU's nothing more than some companies fake the CPU frequency grinding (REMARK) into a high frequency, because if these companies can produce a CPU, then they would have to launch its own brand. Now available in the market, REMARK the main CPU INTEL products, and lcd screen laptop battery Acer AC Adapters  PENTIUM2, 3 the process more difficult, there is not fake, AMD's CPU and CYRIX margin as indicators of small, low prices, so it's little REMARK . These are polished CPU has some features, these features can be identified. a, all polished, the positive mark in the CPU will have some friction, traces b, rubbing his hand writing, the writing will be altered easily after being erased c, the machine test, the CPU frequency jump one, two a grade, if there is crash,, Huaping and so on, then the quality would have considered. In addition, the CPU available in the market generally have two boxed and bulk. In general, the box is bigger insurance coefficient, and bulk is not to say, the bulk of the CPU to buy depends on the level of the purchaser's identification.

3, memory

There are several fake memory: one is the REMARK, the altered into a high-speed low speed, and second, there will be a bad place with a good mix of chips, three are from different manufacturers, different speed chips removed to fight and thrift, Fourth, poor memory with counterfeit brand-name products. These fake memory cost method based on several characteristics of the above is also very easy to identify, for REMARK memory, we can hand rub on the chip, if grazed after a fade, is false. The combination of the old chip, we see the chips on the memory and, if different manufacturers, different time, different speeds of the chips is false. In addition, manufacturers of products in the appearance of the formal point of view, it is sophisticated materials, fine workmanship, neat chip, and poor memory, poor materials, rough, irregular edges of circuit boards.

Display the most important in the purchase of environmentally friendly features is that it is not radiation, energy saving. Is best connected in the selection of the host try to tune into a white screen to see if there is no noise, and in accordance with the instructions to the display resolution, refresh rate, color to the highest, see if you can achieve. Also, be sure not to covet the small cheap, too cheap to buy that monitor, because, first, the monitor is not cheap eco-friendly, not good for your eyes, after all, is against it every day, Kan Ma; Second, there are some renovation now displays, looks brand new brand new internal parts is indeed old, I had met a new 15 'monitor the situation of 800 yuan to buy, it can imagine something inside.

To minimize the number of battery
    The battery charge and discharge is directly related to life, one charge, the battery a step forward to retirement. Often several times a day if the power plug, and the laptop is equipped with batteries, greater damage to the battery. Because each access to the equivalent of an external power supply to charge the battery once the battery life shortened by a natural. Nevertheless, the above theory, but each time it is very convenient to remove the battery, plus there is no battery, if a sudden power-down will lead to data loss. Therefore, we do not recommend users to remove the laptop battery. However, if the customer really want to save battery power or use most of the time, but also to avoid the risk of power failure, you can choose to use an external power supply when the battery removed.ACER travelmate 290 Battery  ACER travelmate 2000 Battery  ACER travelmate 800 Battery  ACER travelmate 6000 Battery
3. Electricity charge and avoid exhaustion after the long charging time
    Regardless of laptop use nickel-metal hydride or lithium electricity, to power after the exhaustion of a certain charge (charge less than 1%), which is the best way to avoid the memory effect. Lithium also have memory effect, but it is the memory effect than nickel-metal hydride smaller fills, only to fully use the battery to charge it after completion. Part of the charge and discharge the battery which could lead to the chemical properties of the batteries are inconsistent, so the battery performance will back down.
    Recommended every few months to conduct a deep discharge battery to optimize battery performance. Specifically: disabling the operating system and BIOS power management features, battery powered, has been used to the system shutdown. Then connect the AC charger has been full up. BIOS and operating system and then restore the power management settings.
    After a long period of storage batteries, and battery has a natural discharge process, has the natural discharge is over, this does not affect battery capacity. The first charge, you should continuously charge the battery to 12 hours, and the loop to fully charge and discharge times (see the battery maintenance section) in order to wake up completely new battery, if this is not the battery is stored for a few months use, it is also recommended for three complete charge and discharge. If a battery by 12 consecutive hours after charge and discharge cycles, or three times still can not charge this battery can not be used needs to be replaced.ACER travelmate 8000 Battery  ACER travelmate 2300 Battery  ACER travelmate 8204 Battery ACER BATBL50L6 Battery
    Understand the above information, we use the machine in the process to note is: 1 machine in use, the battery, as far as possible should be feeling discharged. 2 regular (two months) of the battery is fully discharged battery. 3 If the battery problem, it is recommended to first try and the service center or test battery.

a long time to remember to leave off the screen. If you have something to leave, then we must remember to turn off the screen, the shortcut key is fn + f3, this way, the screen will not be bright white.vaio vgn-s4xp Sony Battery vaio pcg-z1rsp Sony Battery

5, not pointing country, to pay the cost of dead, Oh, should not the hand, tip pointing objects such as screens, to pay the price, likely to cause dead pixels, distressed too late. Battery aging, reduce the use of time, it will make people go out regularly with a laptop is not convenient, the mood will be more irritable, for battery aging problem, other than buy a new battery, there are other methods to repair the battery , let the other way Laijiang Jiang:pcga-bp71 Sony Battery vgp-bps2 Sony Battery

If you interrupt the charging process since the accident, its internal chemical reaction will occur complex changes, at this time is likely to affect battery life. To this end, the depth of the discharge and charge is to protect the laptop battery a good solution.

Tip, if your laptop unfortunately there is no specific discharge software, you can follow the steps below. First, disable the screen saver in Windows Power Management power scheme will be set to "always open", and the Alarms tab will be "low battery alarm" is set to 10%, the operation is set to "No Action." Then the "power shortage alert," set to 3%, operating as a "waiting" while the screen brightness to the highest. Save all the data before the work and confirmed that more than 80% battery after the power and unplug all external devices.PCGA-BP4V Sony Battery pcga-bp2nx Sony Battery

Discharge end of the notebook will automatically shut down after, then plug in the power to charge laptop, this process can be repeated 2 to 3 times. In fact, this approach aims to make continuous small current discharge batteries, which discharge state in our daily use can not be achieved, the effect of discharging those dedicated basically the same software.

Again, remember: over charging and over-discharge of lithium-ion battery will cause permanent damage to the anode and cathode, which is the battery life question from the start with the battery material, the current laptop battery is divided into three types: 1. Nickel cadmium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Nickel cadmium NI-CD, Ni-MH NI-MH, Lithium-Ion battery LI.
1. Activate the new batteries vgn-t2xp/s Sony Battery PCGA-BP2V Sony Battery
General practice is a new company laptop battery at the first boot with a small amount of electricity should be at this time, you should not use an external power supply, but the battery in the power exhausted, until the shutdown, and then use an external power supply charge , we must until the charging light turns off. And then also after the exhaustion of the battery power is full, repeated three times, in order to activate the battery.a long time to remember to leave off the screen.
