Cleaning and maintenance of notebook computer

One, the shell of curing 1 To prevent wear and tear, for the most vulnerable of the lid, we can buy it on the market of plastic protective film, and then stick it on the roof, although a bit not good-looking, but can still play a large role in protection, similar to the mobile phone screen protective film. Some netizens reflect, time grew, the corner of the machine is easy to appear off paint, here we can refer to the protection of the new TV method, is cut into small pieces with transparent tape, stick to the fringes are easy to wear, so do not affect beautiful, but also can have very good protection effect. 2 Clean the shell to note that in order to prevent the accident, when start to clean, be sure to turn it off, cut off power supply, remove the battery. Some machines shell is a composite material containing titanium, opened the screen easily at ordinary times in the shell on either side of the left hand, long is ugly, you can use a wet towel with some warm detergent, wipe gently leave fingerprints at ordinary times, remove HanJi and oil stains, then wash clean towel, wipe with a wet towel, and then air-dry. Second, cleaning and protection of the screen Notebook, the service life of the parts are made of and this is the most fragile inside, I'm afraid is the LCD screen, LCD screen, a normal use of time, generally is about 5 years, with the passage of time, the laptop's screen will be more and more yellow, this is the screen inside lamp aging phenomenon, very normal, pay attention to the screen in the daily use of all cleaning and maintenance. 1. The screen is the most infected with dirt easily, at ordinary times with dry soft hair brush to brush off. When necessary you can use the laptop for cleaners and clean cloth to clean the screen of dust and fingerprints. 2. Do not use hard objects touch screen directly, otherwise it will lead to permanent damage of the screen. 3. To avoid the strong sunlight direct irradiation of the screen, the strong sunshine illuminate is easy to cause the aging of the screen. 4. Do not use the computer for a long time to shut down the screen, such not only can save power and reduce the screen not white. Third, the use of the keyboard and clean Laptop will inevitably enter the dust in daily use, affect the use of the computer, so the keyboard in the use maintenance is particularly important, 1. In the case of conditional can choose to use an external keyboard, so can reduce the wastage of the keyboard. Or you can choose a laptop keyboard film, it is more convenient, beautiful and can protect the keyboard, prevent dust and the keyboard. The effect of the wear and tear 2. Daily cleaning job, there are two, one is thoroughly clean, need to remove the keyboard to clean, it is more complex, for the average person is not in operation; After another is simple and clean, can turn it off, will lead to come over, laptop keyboard gently with the hand, make the inside of the glove with gravity dust fall out; A small combination brush pen can use fur below the key cap impurity removal; You can also use compressed air to remove the bellows blow out. 3. Some on the keyboard of the machine has the trackpoint, this contributes to the operation is convenient, but in general the mouse rod has a rubber sets of above, the rubber sleeve if the user is often very hard to use in the long run will also deteriorate, fall off, so usually also should pay attention to protect. At ordinary times is pay attention to prevent sun direct illuminate. Use at ordinary times when attention to personal hygiene, reduce the trackpoint clean and thus to minimize damage.

Laptop battery repair methods

Method one: laptop batteries, especially lithium battery unused for too long or just repaired, it charge curve and discharge curve have certain deviation, need to use full after several cycles and procedures of the real correct repair their charge and discharge curves, we also called self learning process of the battery. Set (this is the most relation to can repair the battery to the best of the most important step. Please do not need to pay attention to) a, open the control panel power supply options to power my computer use, the use of battery this time parameter selection for alarm item never two options of the box, the purpose is when the battery down to a few percent to application response corresponding operation, don't let the battery power really after, so that the battery itself revised its lowest power with curve 0% charge and discharge: as above after setting, as full of put the principle to the battery charge and discharge, two or three times back and forth, the curve of cell migration can be repair. Note: make sure the battery when charging full, is the best way to shut down filling a few hours or one night, and then pull the discharge, until the computer automatically shut off. Such back and forth at least two cycle method Method 2: the battery is in use and charge the unstable factors will cause the loss of the capacity of the battery, but the decline is not caused by aging, so the appropriate calibration is to be able to make this part of the lost capacity recovery. So of battery calibration work is necessary on a regular basis, such as 1-2 months at a time. Like Compaq and IBM laptop itself is in the BIOS or power management program provides the battery calibration function, so use the two brands can friends according to clew operation can be. Brand for those who did not provide the functionality of the user can follow the steps below: I 1. Set the screen saver to "no" 2. The power use in Windows power management scheme is set to "open", and closes the menu associated with the equipment the following full set to "never" 3. "electricity shortage alarm" in the alerts TAB set to 10%, the operation is set to "no operation"; Will be set to 3% power shortage alarm, operation for the "standby" 4. The screen brightness to the highest % 5. Confirm that all Windows are closed, and save all the data before work 6. Confirm the battery after more than 80%, unplug the power and all external devices, at this time if the screen brightness automatically, so please send it to the brightest OK, you can go to bed, after the discharge laptops will automatically shutdown, after plug in the power supply for notebook batteries, attention must be full filled with again after boot, and then the restoration of power supply solutions to calibrate before setting.

Development potential of lithium battery

Lithium-ion batteries have A lot of batteries do not have the characteristics of: a. the weight of the high energy density lithium ion batteries are the same half of the capacity of nickel cadmium or nickel metal hydride battery, volume is 20-30% of nickel cadmium, nickel metal hydride 35-50%. B. high voltage of a lithium ion battery monomer working voltage is 3.7 V (mean), equivalent to three series of nickel cadmium or nickel metal hydride battery. C. no pollution lithium ion battery does not contain harmful metals such as cadmium, lead, mercury. D. do not contain metallic lithium lithium ion batteries do not contain metallic lithium, which is not affected by the transportation regulations prohibiting in passenger plane carrying lithium battery, etc. E. high under normal conditions, the cycle life of lithium ion battery charge and discharge cycles can be more than 500 times, lithium iron phosphate (hereinafter referred to as phosphorus iron) can reach 2000 times. F. no memory effect memory effect refers to a nickel cadmium battery in the process of charge and discharge cycle, the battery capacity to reduce the phenomenon. Lithium ion battery no such effect. G. quick charge using the nominal voltage of 4.2 V constant current constant voltage charger, can make the lithium ion battery charged at 1.5-2.5 hours; And the new development of phosphorus iron lithium electricity, can be recharged in 35 minutes. Small lithium battery industry in the 1990 s, is now at the mature stage. Lithium battery starting in the 70 s, but it was not until the 90 s security remains unresolved, the main reason is to use a metal lithium anode materials, easy to explode. Until SONY company adopts carbon as cathode materials, the safety problems to solve, since then the lithium battery in the computer, mobile phones, digital cameras, and other fields has gained popularity. Traditional energy depleted, power lithium electricity gradually valued, the anode materials is developing rapidly. Small lithium electricity using cobalt acid lithium and carbon as anode materials, but if used on the new energy vehicles, the following problems: first, cobalt as a scarce resource, the high cost; Second car in bring large current charge and discharge in the process of acceleration and deceleration, lithium anode deposit, and production of crystal, through the film, causing short circuit batteries, organic electrolyte under the condition of high quantity of heat explosion. Starting in the 90 s, American professor Goodenough invented the lithium iron phosphate, and the material ratio performance is good, structure under high current density doesn't change, so as to make the lithium electricity application in power battery is possible. But lithium iron phosphate has a lot of problems need to solve: low voltage (3.3 V, cobalt acid lithium is 3.3 V), the energy density is low Although the power li-ion battery is defective, but the problem can be solved in the development, industry promising in the future. Battery as a system, although the anode material in the past few years has developed rapidly, but membrane, electrolyte, anode and there are many problems to be solved. 1) at present there are many kinds of lithium battery cathode materials, the most main or carbon materials, is middle c d ball which is widely applied, the dragon via electronic technology (shenzhen) co., LTD has industrialization. But used in the power li-ion battery also need to solve large current charge density of lithium in the cathode material deposition problems; 2) electrolyte can meet small lithium electricity application at present, but the application on the power li-ion battery need to be modified, such as flame retardant research; 3) polymer diaphragm need hole closed, at high temperature is improved to avoid the battery short circuit, etc. The short term, power lithium electricity still exist many problems, but if looking for a long time, with continuous development of technology, industry promising future is good.

Maintenance of the battery

Laptop batteries and computer also need maintenance, so that we can make it more long service life. We don't have to unplug battery in the case of using dc power supply, because an automatic battery charging protection function, in the case of full of electricity we use priority is connected to the laptop dc power. If we shall not apply to the laptop for a long time, you can keep the battery removed in a dry, ventilated environment. Every month has a full charge and full discharge twice to ensure, which is good. In addition it is important to note that the battery away from damp, high temperature environment. Sometimes can't fully charged batteries, that might not be the battery problem, we can check the charger cable or is whether the computer's power management system problems. If accidentally make a battery by collision, please don't install it immediately to the computer, need to wait for a period of time, observe whether the battery is leakage condition, avoid it damage to the computer. If batteries are always will be loaded on the computer is not get off, take off the AC power supply, because his cell's environment it is impossible to absolute insulation, and the cells in the integrated control circuit, so even when shut off the computer power supply battery will discharge gradually. Again when connected to AC power supply, the battery will start to charge (most of the battery is designed to start charging battery under 95% design different type battery is different), so every time when open or shut off the power, the battery will be repeatedly charging and discharging. It has very high voltage nimh battery memory effect to damage is very big, although buried ion electricity so electrical billion effect is relatively small, but for a long time not fully charge and discharge will also to a certain extent, reduce the battery life; In addition, the heat generated by the computer at work also will affect the service life of batteries. So in computer power supply is stable under the condition of using environment, suggest that we'll take out the battery and separately USES the power adapter, power supply, the purpose is very simple, is to avoid the battery frequently under the condition of incomplete discharge is charging.
