Battery
The first thing a new laptop user should pay attention to is the battery. The biggest advantage of a laptop is that it can be carried around, and this feature is undoubtedly linked to the battery. Without a battery, all you have is a piece of high-tech junk. The electrical characteristics of a new battery when you start using it are very different from the way it behaves after a period of time, mainly due to the fact that the charging process ends prematurely and the power does not last long after the charge. As you know, these problems can be improved by charging/discharging the battery several times to get the best performance from the battery.
It is important to note that while a brand new battery can be brought in and charged straight away, it will often not perform at its peak if the user doesn't use it correctly at the start of operation. When you get a new machine, don't be too busy charging the battery. Because laptops are shipped with a small charge from the manufacturer to test the functionality of the battery, there is still some power left in the laptop you're getting. Please turn on the laptop first, try to use the laptop battery power to the alarm or automatic standby level to start charging. The default settings in XP are 10% warning and 3% auto standby. Then fully charge the battery with the computer on or off. Unplug the power adapter and discharge the remaining charge. A general rule of thumb is to charge and discharge the battery 3 times in a row, so as to allow the battery to fully warm up and really take advantage of its potential performance.
LCD screens
Newly purchased laptops come with LCD screens that are very fragile. Manufacturers tend to stick a layer of protective film on the screen to achieve the purpose of protecting the screen, this layer of protective film in the use of the former need to be removed, because if not revealed will seriously affect the screen image display effect. In the process of revealing the need for attention, some computer screen protector is very tight, when revealing must be slower, along a corner of the screen, step by step to tear down the protective film. Never use too much force, too fierce, so as not to damage the screen, so that its premature aging yellow. And for some users who often use laptops, you can consider applying a screen protector to better care for your favorite machine.
Outsourcing and insourcing
Choosing a quality laptop bag is essential. After all, for the vast majority of laptops, mobility is an innate characteristic. The right laptop bag will not only give them the most personalized protection, but more importantly, will effectively save your laptop from the elements. This is perhaps even more important for new laptop users to note that not all original laptop bags are really appropriate. With the ordinary office bag is different, a really well-designed laptop bag should first have enough strength and protection of the four sides of the compartment, for the laptop to support a safe and comfortable "love nest". The ordinary office bag is often too large space and soft frame design, can not effectively isolate the outside world of the accumulation of pressure and impact. Secondly, it should have a reasonable accessories compartment design, such as power supply should be set aside next to the side of the laptop, so as not to be accidentally squeezed when the power plug scratches the laptop LCD screen. At the same time, a good laptop bag should also have a certain waterproof radiation resistance.
Two daily maintenance and LCD maintenance
Laptop as a portable mobile computing devices, in fact, the major manufacturers in its ruggedness, durability and so on has done a lot of work, but then again the rugged laptop, but also due to the user in the use of the process of negligence and failure. So how can we make users try to avoid the daily use of mistakes is the main problem we need to discuss.
1 Need to pay attention to some of the situation
The following is a laptop more common easy to damage the factors, but also we usually need to pay attention to some of the situation.
Vibration
This includes drops, shocks, taps, and placement on surfaces that are subject to greater vibration. External vibration while the system is running can harm or even damage the hard drive, and vibration can likewise lead to damage to the case and screen.
. Humidity
Humid environments also do great damage to laptops, and storing and using them in humid environments can lead to corrosion and accelerated oxidation of the electronic components inside the computer, which can accelerate damage to the computer.
.
. Temperature
It is also essential to keep the computer at the recommended temperature. Using the computer at excessively cold or hot temperatures accelerates the aging process of the internal components, and can even cause the system to fail to boot.
.
Strong electromagnetic interference will also cause damage to the laptop, such as in telecom rooms, high-power transmitter stations, and power plant rooms.
On the topic of routine maintenance of laptops, we will explain the different components of laptops below.
2, LCD maintenance
Liquid crystal display (LCD) is the most important output device of the laptop, but also the most delicate components. The maintenance of the display is crucial for the laptop as a whole. Because the panel material that makes up the LCD is very fragile and easily broken, once the outside world exerts too much force on it, it will cause irreparable damage to the LCD, such as display blurring, water ripples, and other phenomena, thus affecting the display output effect. If this causes the LCD to crack, screen replacement is the only way. But its expensive price will generally account for about 30% of the entire laptop, so usually try to avoid the LCD suffered a frontal impact, such as pressure, smashing, beating, etc., and do not flirt with as some people said the laptop as a pillow, as a footrest ... even if it is the work of the BM ThinkPad so that the design of the more sturdy Even the BM ThinkPad, which is designed to be relatively sturdy, can't stand up to this.
If you often use a laptop for a long time, the brightness of the screen will generally be dimmed for about 2 years, and the screen will be yellowed, which is the aging of the LCD display. The aging speed is what we care about, which has a lot to do with the length of time the LCD display is used. For laptops, although it has the advantage in portability, but it can not be turned on for a long time as the desktop. The display itself does not emit light, it uses a backlight tube to illuminate, and the lamp has a life expectancy, to reach the nominal time after the brightness of the LCD screen is basically reduced by half. Laptop LCD screen life is generally labeled as 5 years. Of course, this is not to deliberately reduce the use of laptop time, after all, the computer is used to use.
. How to clean
According to the principle of reflection and transmission of light on the LCD screen, the surface of the LCD screen with a number of layers of film with a special chemical coating of chemicals, so that the external light processing, on the one hand, refracted into different proportions, so that the reflection of light can be to change the direction of the original and offset each other; on the other hand, can maximize the absorption of foreign light, change the wavelength of the light propagation and the direction of the reflection, after the After such treatment, can minimize the reflection caused by foreign light on the screen, the reflectivity and reflective area produced on the screen to a minimum, so that LCD monitors can be used in any poor light environment, even in the outdoors still shows a bright and detailed picture quality effect. Thus, the LCD screen surface coating coating, the LCD screen is particularly important. We mentioned earlier that one of the roles of the screen protector is to protect this layer of coating film.
When wiping the screen, you can use a neutral cleaning agent to clean the surface stains. The correct cleaning method is: first of all, use a computer cleaning brush to remove the dust and particles on the LCD screen (so as not to clean, large particles scratch the surface of the LCD, resulting in irreparable damage), and then use a microfiber cleaning cloth to gently wipe off the remaining dust and ordinary stains. If you encounter more stubborn stains, please cooperate with the use of special LCD screen cleaner sprayed on the cloth or LCD screen, the stains will be wiped off. In the wiping process, be sure to always follow a direction or from the center of the screen outward gently rubbing, never draw a dragon. LCD screen cleaning should be carried out regularly, generally 5 a 7 days can be cleaned once (according to the LCD screen unclean situation), but frequent scrubbing will likewise have an adverse effect on the LCD screen. Dry the LCD screen, and then use a dry soft cloth to clean once, and then close the screen. As we mentioned earlier, one of the functions of the screen protector is to effectively protect the outer chemical coating of the screen from dust, fingerprints, and grease, so that the outermost layer of the coating is not prematurely oxidized.
Precautions:
A, absolutely prohibit the use of water or alcohol and other corrosive liquids to clean the LCD screen. This is because the liquid crystal has a strong water permeability, if you do not want the screen because of water and color water ripples, remember this point.
B , absolutely prohibited in the LCD surface pouring any liquid, such as in the surface of the LCD screen spray cleaner, to not downstream prevail;
C , do not spray the cleaner directly to the keyboard;
D , please use the special LCD cleaner, cleaning LCD screen;
E, prohibit the use of coarse cloth cleaning, so as not to damage the surface
. Avoid shaking
The articulation part of the laptop screen opening and closing, this part is very easy to damage. Many laptop computers after a period of time will appear screen becomes very loose problem, the serious ones have not been able to lock in a certain angle, can only rely on other objects to support the line. At the same time the articulation of the part is also very easy to crack, so you should try to open and close the laptop screen every time some light, some slow. In addition, when using a laptop, you should avoid frequent back and forth shaking of the screen (e.g., in a bumpy car, placing the laptop on your lap to minimize screen shaking), which greatly reduces the chances of this problem occurring, and avoid opening and closing the screen too quickly and violently!
In addition, it is important to note that bright light will accelerate the aging of the display, whether it is a CRT tube or LCD display to avoid sunlight, you should place the display in a weak sunlight exposure or no light in the place; or in the light of the room, hang dark curtains to reduce the intensity of light. Reduce the long-term display of fixed patterns to avoid excessive local aging of the display.
3, shell and wrist maintenance
. Shell maintenance
In order to obtain beautiful visual effects and cost budget, most manufacturers use plastic (or composite metal materials) plus coating of the shell, this shell has a beautiful appearance and a good sense of touch, but at the same time also bring some small trouble to the user. If the usual hairy feet are not careful, the shell of the notebook - especially the top part will soon be scratched and bruised, revealing the unsightly bottom layer of material, to a certain extent, affecting the overall appearance. Especially sony, samsung this kind of design pay attention to the beautiful notebook, more likely to become a big flower face, on the contrary, the small black of the BM, time will not have too much change. At the same time, with the development of the laptop market and the influence of fashion trends, advocating freedom, the pursuit of individuality of young people more and more unable to tolerate the same laptop design and monotonous color. The appearance of laptop design and color matching urgent need for "personalized" transformation. So we have to prevent the appearance of wear and tear in advance, and the market special high-quality shell protective film is extremely rare. Special laptop shell color film, not only beautiful and personalized, but also can be very good to protect the top cover is scratched. In addition to the front of the notebook, in fact, the sides are equally susceptible to wear and tear for a long time and arm and wrist wear. If it is summer and also suffered from the erosion of sweat, even the best material can not stand such a toss. You can put some labels on it, not only beautiful and can reduce the wear and tear of the shell. In addition, when using a laptop, it is best to remove the watch and other metal jewelry, so as to avoid hard objects scratching the laptop shell.
For the shell of the cleaning also need extra attention, you can use a soft cloth with some water or special cleaning fluid to wipe. If you encounter oil stains and other stains are not easy to clean, you may want to try some wax cleaner (such as Bili Zhu and automotive cleaning cream wax), but do not use organic solvents such as alcohol, otherwise the shell surface coating is dissolved that can not look good.
Maintenance of the hard disk
Hard disk as a computer mainly mechanical movement in the way of work, but also the most easily damaged parts. Extra care should be taken to protect it.
Although the laptop hard disk is much better than the desktop hard disk, but after all, the principle and desktop hard disk is the same. The head arm drifts across the platters at 54OOrpm (note: rmP is the number of revolutions per minute of the motor spindle in the hard disk, the higher the speed the greater the internal transfer rate) or even higher, and a sudden bump or even a tiny jolt can have serious consequences. Many laptop manufacturers also minimize the impact a hard drive can take with protective pads and reinforced bays. But that doesn't mean you can just move around with a laptop that's reading and writing.
Automatic shutdown of the hard drive
Like LCDs, you can set the power management options to automatically shut down the hard drive after a certain amount of inactivity, which saves battery power and reduces mechanical wear and tear on the hard drive when it's spinning for long periods of time.
Hard drive optimization
With the speed of other components, the hard drive has become the biggest bottleneck in laptop performance, with desktop hard drives entering the 10,000-rpm era, while laptop hard drives are still in the mainstream at 5400 rpm, and high-end machines are only at 7200 rpm. So in order to effectively reduce this speed bottleneck on the user's application of the impact, in addition to do a good job of the system software performance optimization settings, as far as possible, the commonly used programs installed in the system partition, because the hard disk partition more back, read the disk speed will become slower, if you also put the program like Photoshop into a very back partitions, undoubtedly adding insult to injury. You may want to dedicate a small partition to the operating system and some program cache are pointed to that partition, so that you can reduce the impact of too much fragmentation on the speed of the system partition. If you have enough RAM (more than 1G), you can search the Internet for ramdisk, a small program that virtualizes the hard disk with RAM. It's self-explanatory, and you'll see what it's all about once you've used it.
.
I don't know if you've ever noticed that some people's laptops have frequent hard drive problems, while some people's hard drives haven't had any problems for a long time. You may feel very strange, the same brand, the same model of laptop, different people use, hard disk life is not the same, want to understand it? In fact, the length of the hard disk life is mainly determined by the user's usual habits, the following list of several need to pay attention to the use of skills:
1. Try to minimize the parallel start multiple hard drive read and write tasks: this way the operating system will make the hard disk head for frequent shift arm scheduling, accelerating the aging of the head motor, the head will be very easy to get out of the problem for a long time.
2. Disk optimization: If necessary, you can format the hard drive, reinstall the system, and organize the disk. These operations are good for the hard disk, can make the hard disk files in order to rearrange. When the file is accessed, it can be found more quickly, so that the addressing efficiency of the hard disk increases, reducing the movement of the magnetic head.
3. Keep the hard disk as cold as possible: When the inside of the hard disk is above a certain operating temperature, it will deform due to high temperatures. This can lead to problems such as increased motor friction on the platters, and can also increase the chances of hard disk errors.
Maintenance of the recorder
. Recorder dust, moisture
Dust and humidity are the arch-enemies of optical storage devices, dust falling on the laser head and other components will affect the performance of the optical drive. Humid environment will make the internal circuitry of the optical drive failure, pay attention to dust and moisture is the most basic means of protecting the optical drive. First of all, to prevent dust from entering the optical drive to fall on the optical head. Before putting in the CD-ROM can be necessary to clean, while minimizing the number of times to open and close the warehouse door, in order to avoid the chassis fan sucked into the air flow through the optical drive, will bring in the dust fell on the laser head. Now many optical storage products have adopted a full dustproof design to ensure the normal operation of the optical drive, extend the life of the laser head. In addition, the humid environment will lead to oxidation of the internal connectors of the optical drive and cause poor contact failure, so try to keep the indoor humidity is not too Bureau.
. If the process of burning bad heat, will not only lead to burning disk failure, but also indirectly shorten the life of the burner, especially in the hot summer, this problem is more prominent. Therefore, the burner should try to avoid continuous long time in the use of the process of burning, the best each time after a disk burner let the burner rest for a while, in order to facilitate the normal heat dissipation of the machine.
. The quality of the disc is very important
If the quality of the recording disc is poor, such as physical scratches on the disc, pits or bubbles and other defects, then the use of such discs on the optical drive of the error correction capabilities of the requirements of the very high, the laser tube power will become very large, the optical drive is frequently in the state of the error correction, of course, is not conducive to the service life of the laser head. It also makes it difficult for recorders to recognize the discs, and even if the discs are barely burned, they can't be played in a normal player.
The better quality and reputation of the burning disc brands on the market are Mitsubishi, Verbatim, Leiden, Sony, and TDK, etc. Generally, the difference in price between the big brand discs and the miscellaneous discs is not very big, so you can't save a small amount of money in order to ensure the safety of the data and safeguard the lifespan of the burner.
Don't open and close the door too often
Since the laser head and spindle motor are at their maximum power after the disc is in the bin, so if you enter and exit the bin too often, it will naturally accelerate the deterioration of these parts, so try to avoid changing the discs as often as possible, and for discs that are often to be used, it's best to copy them to a hard disk. In addition, if possible, try to avoid pushing the disc tray into the warehouse door by hand, because frequent such operations will be very harmful to the optical drive into / out of the mechanical part of the warehouse, will accelerate the wear and tear and aging of the belt, I believe that many of my friends have had the experience of mechanical damage to the optical drive can not be out of the warehouse, it is recommended that it is best to use the tray "in / out button" to close the warehouse door. The best way to close the door is to use the tray's "in/out button".
. Using a virtual CD-ROM drive to play CD-ROM games
In order to save space on your hard drive, many games can be run directly on the CD-ROM. While the optical drive is reading the game disc at full speed, for a long time, this is very unfavorable for many mechanical parts and laser head components inside the optical drive, so commonly used games are recommended to use the virtual CD-ROM software, which saves the contents of the game disc on the hard disk to make a virtual CD-ROM.
. Therefore, only through the correct preservation method can we extend the life of the disk and ensure the safety of important data.
This includes a lot of precautions, such as storing the disc in a special disc rack or disc case, do not put it in a place where the temperature is high, in order to avoid high-temperature deformation of the disc; to choose a dry, light-avoiding place to save the disc, so that you can avoid the impact of light and moisture on the disc; do not make the disc contact with the chemical solution, so as to avoid a chemical reaction directly damaging the disc; do not casually Do not touch the surface of the disc directly with your hands, or squeeze or bend the disc; for discs that need to be marked, avoid writing directly on the surface of the disc with a grease pencil, and do not stick a small strip of paper on it, but should be marked on the disc in the disc case. In addition, in order to avoid scratches from hard objects, discs should be returned to the storage case immediately when not in use, and care should be taken not to touch other objects when in use, and so on.
Finally, the main function of a burner is to back up your data, so there's no need for high speeds or impractical add-ons. With a little care, it can work for us for much longer.
About charging and discharging the battery
This leads to the question of whether the battery should be removed from the machine when it's powered on. This is a real headache. We used some professional tests to see how the battery capacity changes after keeping the battery for a certain period of time under different charging habits and ambient temperatures. According to the test results show that high state of charge and high temperature accelerate the decline of battery capacity. So now you might as well imagine what kind of state the battery is in if you don't take it off. Due to the charging protection circuit of the laptop, the battery is maintained in a high state of charge at 95-100%, while the ambient temperature where the battery is located at this time is at least around 30°C, and if it's a hot day, the temperature will be even higher, what conclusion will you get? Therefore, it is best to disconnect the battery when using an external AC power source, otherwise the battery will be in a hot state for a long time and its lifetime will be affected.
If you are not going to use the battery for a long time, it should be charged to 40% and then stored in a cool place to reduce the rate of its own internal passivation reaction, whereas if it is fully charged and then left in a high temperature, it will cause a lot of damage to the battery. A 100% charged battery stored at 6o°C lost 40% of its capacity after 3 months. For batteries that have been stored and put aside, it is important to put the batteries back into service at least once a month and recharge them again to prevent the battery ions from becoming inactive. As the electric memory effect of the clathrate ion battery is negligible, so halfway charging is not very big damage to it, and it is more afraid of over-discharge (complete discharge). Often on the clonium ion battery over-discharge can only be the result of the battery is prematurely scrapped, those such as BIOS discharge, program discharge, or even connected to a small light bulb discharge is best not to try until you have no choice. So you don't have to wait until you're at O% to recharge your battery.
. Stable voltage is important
Try to use clean power (not too high or too low) as an external power source, and be careful not to connect your laptop's power adapter and high-power appliances (such as an air conditioner) to the same power outlet. The reason is very simple, high-power electrical appliances will form a momentary high voltage when they are turned on or off. If you have the conditions, you can choose UPS equipment, UPS is short for uninterruptible power supply, is able to provide continuous, stable, uninterrupted power supply of external equipment. It can effectively purify the power supply when the external power supply is abnormal, and it can also continue to supply power to the computer and other equipment for a certain period of time when the power supply is suddenly interrupted, so that you can have enough time to cope with the sudden situation.
.
The same dust and moisture are also acting as battery killers, destroying the board circuitry and accelerating oxidation inside the battery, so for long term storage batteries, you can put a film over them to keep the dust and moisture at bay. Don't charge your battery in the rain. Rainy days are often characterized by thunder, and the instantaneous current shock caused by a lightning strike is extremely detrimental to the battery.
7, the maintenance of the keyboard
Keyboard is our most frequent and most likely to accumulate dust parts, look at a keycap to know that it is the best place to hide the dust underneath. Excessive dust can accelerate the corrosion of the keyboard's conductive rubber, which can cause damage to the keyboard's printed circuitry. Think about what a keyboard would look like if it was used as an ashtray by a smoker. It can only be described as miserable!
.
Although most manufacturers have taken into account the durability of the keyboard, especially in the structure of the full optimization, but the water drop through the stone, the problem comes after a long time. Either a key doesn't work well, or the letters wear out. Users should pay attention to the following main points when using the keyboard: first, do not lose your temper with the keyboard. It seems to us that the biggest killer of the keyboard is yourself, many computer users in the crash due to the loss of their own work, can not help but smash the keyboard a few times out of anger. We remind you that this will cause damage to the soft rubber that supports the keyboard keys, and over time the keys will not pop up.
Point 2: Water is the number one killer of keyboards and even entire laptops. Try not to eat, smoke, or drink water on top of your laptop and keep your keyboard clean. Especially if too much liquid gets into the keyboard, it's likely to seep inside the host and short out the wiring, causing hardware damage. However, this kind of damage is not covered by the free warranty, and you will have to pay for the solution out of your own pocket. We hope that users can develop a good habit of eating or drinking away from their laptops to minimize the chance of problems and achieve the goal of protecting their laptops.
. How to clean the keyboard
If we have no choice but to need to need to clean the keyboard, then we can use a vacuum cleaner fitted with the smallest soft nozzle to suck out the dust from key to key. But to really do a thorough cleaning you would have to remove the keycaps one by one, which would be a real pain in the ass. But we can prevent this before it happens. You can use a protective film for your laptop keyboard. This soft film has a lot of uneven keys on it, just enough to cover the laptop keyboard, both waterproof, dustproof, and anti-abrasion, and the price is not expensive. Just when picking one, you need to pay attention to how well it fits the keyboard, and how soft it feels in your hand. If you type on a hard keyboard, it will definitely feel very uncomfortable. In addition, it is also necessary to regularly use a cleaning cloth with an air blow to remove dust in the gaps between the keys.
. Repairing the keyboard DIY
For those whose keyboards have been in the water or have become inflexible, we have a trick for you. First, every key on a laptop is removable. For standard-sized keys, you can use your fingernails to gouge from top to bottom, after which you will see a rubber pad, the keys do not play up with it. You can press this rubber pad with your hand, if it doesn't pop up immediately, then you can replace it with the rubber pad of other keys that you don't use often. Or go to the laptop second hand market to buy one, the price is very cheap, at least much cheaper than you take it to the repair station. For the keyboard into the water users, you need to water into the piece of the keys all open, after a careful examination, if you determine that the liquid did not leak into the computer, then for distilled water or tap water, etc., the natural drying can be, do not use a hairdryer, because the heat of the hairdryer may be on the laptop inside some of the precision equipment to cause damage. For drinks, such as Coca-Cola, etc., these drinks will leave sticky sugar after the moisture evaporation dry, then you need to use a low concentration of alcohol to wipe. When wiping, you should pay attention to every corner, especially the parts of the rubber mat.
.
In addition, there is a little bit of insight to share with you: if the notebook is often used in a fixed location, you can buy an external keyboard instead of the original keyboard. The USB port of the keyboard can be used in general. Some PSZ keyboards are also available through adapters, but some require wiring modifications to make them work. External keyboards are much cheaper than the original, and it won't hurt if they get damaged.
8, pointing device maintenance
Now commonly used in notebook computers on the pointer positioning device has a mouse lever (also known as the pointing lever) and the touchpad two kinds of, the former is mainly by the full range of industrial BM models and early Toshiba , Dell and other models to use, and the latter is one of the most commonly seen to a laptop pointer positioning device.
.
First, let's talk about the maintenance of the touchpad. In fact, it is very simple, the general touchpad are divided into multiple layers, the first layer is a transparent protective layer, the second layer for the tactile layer. Here users need to pay attention to is the first layer, this layer of protective layer main function is to strengthen the wear resistance of the touch plate. Since the surface of the touchpad is often pressed and rubbed by fingers, the role of this protective layer is crucial. Never pay attention to not accidentally let the hard things will be this layer of protective film cut, this layer of film as long as a little broken, the rest of the part will soon fall off, by then the whole protective film fell off, the wear resistance of the touch pad is very fragile, it is easy to due to prolonged friction led to its failure. Of course, to keep the touchpad clean is also necessary, clean the way with the shell is the same, will not repeat.
. The maintenance of the pointing stick
Finally, the pointing stick (also known as the mouse lever), the pointing stick was originally invented by the BM, its main benefit is to save assembly space, users must pay attention to the pointing stick when using the dialing strength, I have seen a lot of the mouse lever was dialed bad laptop. In addition, the general pointing stick has a rubber head, this rubber head if the user is often very hard to use a long time will deteriorate, fall off, so usually also need to pay more attention to protect. Dirt is also the main problem here, you can use a toothbrush with a little toothpaste for proper cleaning. This part at the same time is also relatively easy to damage, we tell you a little trick, you usually use the button when you try to press the center of the position, which will make the inside of the micro-switch force uniformity, so as to increase the service life.
Well, that's basically all. If you don't understand anything, please communicate later. Good luck~~~
