Laptop LCD Screen

As expensive laptop LCD screen, the cost usually accounts for the entire 30% of the cost laptops, while its physical properties make it ideal for notebooks delicate part of the most vulnerable and therefore are used for liquid crystal display screen notebook computers words, it can be described as a top priority. When the user no need to use when best to use a screen saver or display a black screen, this power will only extend the life of the LCD display. If the time out, it should simply shut down, thus extending the life of backlight lamps.

In addition, if the surface of the LCD screen attract dust due to static electricity, the user is using the liquid crystal display screen special cloth to clean your screen, and gently wipe. In addition, frequent use of laptop users, the keyboard may be inadvertently caused by stamped on the screen, so regular cleaning is also very necessary.

Cleaned once a year or so I remember

To make a long-term work computer, users need to learn to open the case for computer maintenance, of course, if you are not sure, or contracted out to professional cleaning once a year, for some brand-name computers, manuals are not free in the state opened the chassis, do not open the case, otherwise it is not given warranty

To carry out hardware maintenance, the average user can not have professional tools, we use the following tools can be easy to get: a Phillips screwdriver, wipe the lens paper, blow up balloons (Paper Tiger), paper clips, a small desk fan.

1. Cut off the power, the connection between host and peripheral pulled out with a Phillips screwdriver to open the case, remove the power box. You will see the dust on the board, with blowing balloons or blowing carefully wipe the tiger skin, in particular, the annex to the panel and power inlet box (air vents) in the vicinity, and the board of the docking site, while

application platform fan blowing to blow up the balloon will be blowing the dust the dust on the inner wall of the chassis box away.

2. Remove the power supply, computer power supply depends mainly on the exhaust fan, so the power box in the dust most carefully cleaned with a blower mounted on the post. Note also that there is no deformation of the leaf fans, especially after the summer heat, aging often

  affects the noise of plastic bigger, this is probably the reason.
1. Placement of the computer room to keep dry and clean, especially the computer table every day (or two or three days, depending on the cleanliness of the room may be) removal. You know, the display is a very strong "vacuum cleaner." Because the environment has to come across negative, display the internal dust thick plot, the weather tide, causing damage to the display circuit board short sparking the accident.Laptop ac adapter AC adapter

2. Turn right (first peripheral, then the host) and off. In fact, this should not be maintained, but many users disagree to this total, or even a computer error to think that even the "soft shutdown" have it all, but also "platitudes." But it is absolutely necessary: ​​"First peripherals, after the host," If you engage in counter-order, and it is possible to make the system not recognize the related hardware, or can not load the device driver.

3. Before using the CD-ROM or floppy disk, make sure anti-virus; installed or have another look at it again after using drugs, because some anti-virus software to compress files in the virus could do nothing.

4. System of non-normal exit or unexpected power outages as soon as possible to drive scan, fix errors in a timely manner. Because in this case, the hard drive will be lost in some clusters of links, causing potential danger to the system, if not repaired, will cause some programs to disorder, or even threaten the stable operation of the systemlaptop 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 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.

How to care and protect a computer, the maximum extension of its service life, is we are very concerned about the topic.hp laptop keyboard toshiba laptop keyboard

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.
