Dell hard disk use and maintenance precautions

Dell hard disk use and maintenance precautions 1, the use of the environment Dust in the working environment, dust will be adsorbed to the hard disk printed circuit board surface and the spindle motor inside. Hard disk work in a humid environment, will make the insulation resistance down. These two phenomena are caused by the instability of the computer work, while the damage to some of the electronic devices, or some of the dust-sensitive sensors can not work properly. So to maintain the work environment of health, reduce the amount of dust in the air. In addition, the user can not open the hard disk cover, otherwise the dust in the air into the disk, head read / write operation when the possibility of disc or head will greatly increase, so the hard disk failure is not allowed in the general conditions Under the open body shell screws.dell vostro 200 power supply In addition, as far as possible not to make hard disk close to strong magnetic fields, such as speakers, speakers, motors, radio, etc., so that the data recorded on the hard disk due to magnetization and damage.latitude hard drive 2, pay attention to high temperature, moisture, anti-electromagnetic interference Hard disk working conditions and life and temperature have a great contact, the hard disk to use the temperature to 20 ~ 25 ℃ is appropriate, the temperature is too high or too low will make the crystal clock frequency changes, in particular, will cause the hard disk circuit Component failure, storage media will be due to thermal expansion caused by recording errors. While the temperature is too low, the water in the air will be condensed in the integrated circuit components, resulting in a very serious short circuit.dell xps 8300 power supply 3, hard disk read and write, can not force power Hard disk in reading and writing (hard disk indicator light will flash), the disc is in high-speed rotation state, if forced to turn off the power at this time, will lead to fierce disc and disc friction, thus damage the hard disk. Therefore, in the shutdown, we must pay attention to the hard disk on the panel indicator to ensure that the hard disk to complete the read and write and then shut down. 4, the correct way to take the hard disk When doing computer maintenance, if you need to remove the hard disk. The correct way is to grasp the hard drive on both sides, and to avoid direct contact with the back of the circuit board, to gently, do not bump or collision with other hard objects; can not touch the hard disk on the back of the board, There may be static electricity, static electricity will damage the electronic components on the hard disk, resulting in read and write cache chip damage. There is not to be charged plug, easily lead to chip damage.inspiron hard disk 5, the correct mobile hard disk, pay attention to shock Mobile hard disk is best to wait for a dozen seconds after the hard disk completely stopped and then carried out. In the boot when the hard drive high-speed rotation, gently shake the disc and the head can be rubbed with each other to produce bad or bad or write head damage. So it is recommended in the boot state, do not move the hard disk or chassis, it is best to wait after the shutdown, until the hard disk completely stopped and then move the host or restart the power, to avoid instantaneous damage to the hard drive. In the installation of the hard disk, the demolition process should be more careful, hard disk movement, transport is strictly prohibited bumps, preferably with foam or sponge packaging to protect, to minimize vibration.dell optiplex 990 power supply Another point to note: that is now a lot of hard disk manufacturers so-called “crash capability” or “shock system” and so on, are in the hard disk in the unused state of shock, crash capability, rather than in the boot state. 6, to develop the correct shutdown habits Hard drive in the work suddenly turn off the power, may cause the head and disc violent friction and damage the hard disk, but also the head can not be properly reset and cause hard disk scratches. Shutdown must pay attention to whether the hard disk indicator panel is still flashing, only when the hard disk light stops flashing, the end of the hard disk to read and write before shutting down. 7, a reasonable partition on the disk The size of the hard disk partition seems to be related to the maintenance of the disk is not great, but the partition is reasonable or not, in fact, with the future maintenance, upgrade the operating system and optimization are closely related, absolutely can not be ignored. The beginning of the appropriate partition size, will remove a lot of unnecessary trouble, and can facilitate future management. 8, disk fragments to be done regularly Disk defragmentation is often done, but if it is the system’s virtual memory on a separate partition, then the Windows system generated Win386. SWP will be generated in a continuous blank cluster, and every time this is the case. As a result, disk fragmentation caused by virtual memory does not exist, which eliminates a large source of disk fragmentation. Moreover, because the effects of debris on audio and video file playback are almost negligible (playback speed and quality depends on the memory buffer settings and CPU capacity), if the user is not a lot of write and delete files, generally only C drive because of browsing Will produce disk fragmentation (the system default path, if changed, you should organize the buffer file where the temporary partition), then finishing the C drive enough. The rest of the songs loaded MP3, video and game partition, one month or even two months finishing once on the line. Because the speed of the system depends on the partition of the installed operating system, as long as the C disk Windows system files remain continuous and tidy, the data structure of other partitions on the system speed and stability of a small impact. Of course, if the user in other partitions also need to regularly edit or delete the file, it should often organize these partitions.2txym 9, less disk compression When the compressed volume file gradually increases will lead to hard disk read and write data greatly slowed down the speed. With the rapid development of hard drive technology, the capacity of the disk today, so it is difficult to hard disk space is often not enough of the situation, and there is no need to use the hard disk compression technology. 10, backup partition table Backup hard disk partition table and check the integrity of the backup for the protection of data on the hard disk is also very important, because the Windows operating system can be reloaded bad, and if the hard disk partition table is broken, the system will not recognize the hard disk, the problem will Much more serious. The use of disk tools, such as Ghost and other tools to the entire Windows system partition backup into a file, and its separate storage, because the hard disk partition table problems caused by hard disk error, it will re-write to the C drive. 11, antivirus can not forget Some viruses on the hard disk stored in the data is devastating, so open the anti-virus software automatically and more automatic monitoring is necessary. When copying information from the external disk to the hard disk, the first disk to check the virus to prevent the hard disk infected with the virus.precision hard drivedell optiplex 390 power supply 12, hard disk appears bad sectors Hard disk, such as the emergence of bad sectors, even if a cluster may have a proliferation of destructive, in the warranty period should be as soon as possible to find businesses and manufacturers to replace or repair, has been the warranty period as much as possible to reduce the format of the hard disk to reduce the spread of bad clusters. 13, to avoid frequent high-level format operation Advanced format is “FORMAT”, this command is a lot of friends are often used, not knowing that the same operation on the disc performance is not a small impact. Xiaobian suggested that if you do not re-partition in the case, you can use the parameter “Q” fast formatting command. FORMAT function in the recovery console can support FAT, FAT32 file system format, and in window9X / ME can only support FAT and FAT32 format, and the new hard disk format, you can not use the fast format parameters. 14, easy not to low lattice It is best not to use the hard disk low-level format operation, this will make the hard disk from the new work in the initial state, so the disc performance will bring a very big impact. It is recommended that if there is no special reason, or not to low-level formatting the hard disk. 15, let the hard disk smart rest So that the hard disk to enter the “close” state, you can work on the hard disk temperature and life to give a great help, this general friends will always ignore this feature, the use of hard disk hard rest can make the hard work in the “healthy” state of the under.

How to maintain dell laptop screen?

How to maintain dell laptop screen? Life notebook has been very common, many young friends have paid attention to the maintenance of notebooks maintenance, but some friends because of the lack of professional maintenance knowledge, maintenance of this notebook is not how familiar with this, in order to higher maintenance notebook, We introduce the notebook screen maintenance knowledge, which is one of the core of notebook maintenance. Notebook screen is the user must first face the Internet, it is the most important laptop output device, but also the most weak side of the notebook, looks more fragile, so notebook screen protection and maintenance for notebook enthusiasts is the biggest focus , Then the notebook screen maintenance should pay attention to what?alienware motherboard ⒈) for the notebook LCD screen to add screen protection film Notebook screen protection film Many friends are in use, the biggest advantage is to prevent dust into the screen inside, in addition to a waterproof, anti-scratch, etc., and better quality screen protection film can also protect our eyes less Radiation damage, so the maintenance of the notebook, the screen protection film maintenance is very important, but need to remind you that the current notebook screen protection film numerous, poor quality of the uneven, I suggest that you try to buy brand and reputation better screen protection film product.dell optiplex 390 power supply ⒉) Notebook screen to open and close the action to be gentle Notebook screen is relatively thin design, itself is not strong, it should avoid the collision screen, another face to face, the screen and the notebook site between a large number of data lines like the connection, so open and close should be gentle, so force balance, Can effectively protect the internal data lines are not easily damaged.h240as 00 ⒊) Notebook screen can not place relatively heavy items Many users think that the notebook closed, the whole looks very strong, like some of the heavier things pressed on the notebook did not, in fact, these are not allowed, it is easy to lead to damage to the notebook screen, resulting in the need to replace the screen.precision lcd led screens Notebook due to excessive external force caused by the display is not normal failure Notebook manufacturers for cost and weight considerations, often on the notebook cover to use the more thin materials, these materials are often unable to resist high-strength collision, and to withstand greater pressure, once the external pressure is too large will lead to damage to the LCD screen, There is water ripples, fuzzy and other non-repairable situation; and this time, we often can only reluctantly change the screen. Therefore, in the usual with the beloved books go out, be sure to pay attention not to pressure on the notebook above, and in the process of moving carefully and can not be heavy pressure on the notebook above.mini tower power supply ⒋) other aspects Notebook screen maintenance should pay attention to the main, the notebook can not be used in high temperature environment, especially many friends with the notebook portability, like the long-term use of the sun outside the notebook, this result easily lead to the computer internal temperature is too high , Affect the life of the notebook; the other use of the environment should pay attention to dry, can not or with the wet, no device easily lead to internal short circuit, resulting in laptop damage.alienware lcd led screens Notebook screen maintenance and protection also need to pay attention to a lot, such as the best not to touch and draw the screen by hand, one is easy to scratch the display, the other static also easy to damage the screen pixels. But the above is the most basic should grasp the notebook maintenance knowledge, hope that the novice friends of notebook lovers have a reference.

Dell’s daily use and maintenance of the laptop keyboard

Dell’s daily use and maintenance of the laptop keyboard Because the keyboard is one of the most frequently used parts of our use, although many manufacturers have taken into account its durability, especially in the structure made a full optimization, but the water droplets to wear stone, a long time to come. Or is a key is not used, or is the letter did not wear.dell latitude parts Users in the use of the time should pay attention to the following points: The first is not the keyboard temper. We see the keyboard is the biggest killer of your own, many computer users in the crash after the loss of their work because of their own, can not help but hit the keyboard a few breaths. We remind you that this will be on the keyboard keys to play a role in supporting the damage caused by soft, a long time there will be a button to play the problem is not up to play. The second point is to try not to eat above the laptop, smoking or drinking water, keep the keyboard clean. Especially too much liquid into the keyboard, it is possible to make the circuit short circuit, resulting in hardware loss. We want users to be able to develop a good habit, when eating or drinking away from the laptop, which will minimize the probability of the problem, to protect the purpose of the laptop. Secondly, we recommend that you can buy a laptop keyboard dedicated soft pad, this soft plastic above a lot of uneven keys, just to cover the laptop’s keyboard, both waterproof, dustproof, but also Anti-wear, and the price is not expensive, the general computer market can buy. In addition, it is also necessary to periodically clean the dust in the gap between the cleaning cloths.dell inspiron parts 6w6m1 For those who have been the keyboard or has been inflexible users, we teach you a move. First of all, every keypad of the laptop can be opened. For the standard size of the button, you use a nail from top to bottom hard to pull a pull can be opened, and then will see a rubber pad, the button can not play it just a relationship. For those who can not play the button, you can press the rubber pad by hand, if you can not play up, then you can use other less commonly used button rubber pad instead, or go to the notebook second-hand market to buy a , The price is very cheap, at least you get much cheaper than the repair station. For the user of the keyboard water, you need to put all the buttons into the water to open, and then carefully check, if the liquid does not leak into the computer inside, then for distilled water or tap water, etc. , For beverages, such as Coca-Cola, etc., these drinks will dry after the evaporation of sticky sugar, then you need to use low concentrations of alcohol to wipe. Wipe the time to pay attention to every corner, especially the rubber pad parts.dell inspiron 530 motherboard diagram Pointing equipment maintenance Since most laptops come with a touchpad or mouse lever instead of a mouse, and many users are already accustomed to using these two methods to control the cursor on the screen, so as a regular use of the laptop parts, we It is necessary to tell you about the two kinds of input equipment, routine maintenance skills. First talk about the maintenance of the touchpad. In fact, very simple, the general touchpad are divided into multiple layers, the first layer is a transparent protective layer, the second layer for the touch layer. Here users need to pay attention to the first layer, this layer of protective layer is to enhance the main function of the touch plate wear resistance. Since the surface of the touchpad is often pressed and rubbed by the fingers, the effect of this layer of protective layer is critical. Do not care to let the hard thing to cut this layer of protective film, this film as long as the break a little, the rest of the part will soon fall off, when the entire protective film fell out, the touchpad wear resistance Very fragile, it is easy due to prolonged friction caused its failure. Of course, keeping the touchpad clean is also necessary.dell part Here is a talk about the mouse rod (also known as the pointing stick), the mouse rod was originally invented by IBM, and its main advantage is to save the assembly space, the user must pay attention to the use of mouse rods toggle, I have seen a lot The mouse rod is misplaced by the laptop. In addition, the general mouse rod above a rubber sleeve, the rubber sleeve if the user is often very hard to use a long time will degenerate, fall off, so usually have a lot of attention to protection. Dirty is also the main problem here, you can use a toothbrush to dip a little toothpaste for proper cleaning.
