1, shut down the system, unplug the power cord and mouse peripherals, starting from the back of the fuselage disassembly; 2, find the location of the optical drive, with a Phillips screwdriver to remove the screws; 3. Use a screwdriver to eject the optical drive; 4, parallel to remove the optical drive, you can clean up the dust; 5, the next is the installation of optical drive,

The independent graphics card has a very troublesome place is the fan easy to accumulate the dust, the suggestion buys the video card to buy the wind to be less cold, buys back to use several months to accumulate the dust.Dust Removal steps:1. Unplug the monitor plug2. Remove the video card from the motherboard3, at the bottom of the radiator red plastic cover layer of 4 long screws down4, Unlock the radiator face 3

The prototype is the computer sample that is displayed on the counter. Many friends who buy computers are worried that they will be given a prototype by the merchant. The prototype is likely to have many problems relative to the sale. For example, the computer's touch screen is very inflexible, internet watching TV will often be stuck, the longest can be stuck for more than 10 minutes. 1, look at the soles of the feet, if the soles of the feet are dirty, or have scratches, the description is a

the chassis noise reduction For the chassis, it itself is the most quiet of many accessories, but because of the installation of other accessories and thus become the distribution of all noise. For example, in 5.25-inch and 3.5-inch positions, the hard drive and the optical drive will vibrate at work, and the side panels, front and rear panels will also resonate because of the fan rotation. The easiest way to solve these resonances is to tighten their mounting

possible wiring problem, we can refer to the following method to resolve Phone symptoms The mobile phone is broken, or the touch part is not normal, for example, the mobile phone backstage can not close, the red part cannot press, the dialing also is not normal. Specific steps Step one: Dismantle the machine to begin, need to take out the Cato first, otherwise disassemble the motherboard easy trip. Step two: The bottom

will be from the fan demolition, fan cleaning oil and heat sink clean three parts detailed explanation fan dust cleaning process. Before we clean up, we must buy some cleaning tools: a small soft brush, screwdriver, towel, alcohol, oil, knives, toothpicks and so on. One brush, screwdriver, oil is an essential item. Removal of fan and cleaning oil Generally speaking, the power of the fan is the most difficult to clean, because the demolition is very troublesome. Here we give you a detailed expla

studied in many industries, and I have studied with the hospital, an engineer is there like an attending doctor, and his employees are like nurses. I want the screws you give me the screws, I want the tires you give me the tires. It is still very slow to find it. We know that later this world-famous electrical Automation era (which is now a lot of factories are using the pipeline operation) is the inventio

Like to hang the Monitor on the wall. Before the display wall hangs, we need to remove the base of the monitor. How to disassemble the monitor base, because different monitor base design may differ, the dismantling method will be different. 1, the bottom of the LCD is mainly divided into the base and the shaft two parts, the following is the specific operation: the base demolition 2, after the demolition of the base, the next thing we have to do is to disassemble the hinge, as follows: First

hard disk can not have a common vibration phenomenon: the hard disk is in a stable state of rotation at work, such as the current mainstream PC hard disk is 7200 rpm. In the regular rotation of the hard disk may be in the same common with the PC chassis, so that the hard disk will be in the state of shaking, although the amplitude is very small, but for a long time in such a state, the damage to the hard disk is very large, the quantitative changes will evolve to a qualitative change, and final

Dell n4010 Notebook How to remove the machine clean ash? Female colleagues took the machine today, I look at the machine shell is very dirty, but also said to be lesbians, it seems that units of Dongdong, is not very cherish. I conveniently swept the top of the ash, she felt a little embarrassed, busy said: Has not cleaned up, did not give the computer hygiene. Take another picture! First the bottom of the D-shell screws all removed, and then b

, re-request motherboard test failure is still resolved. Finally, the computer installed on the boot press F2 test can enter the BIOS, about half an hour before the BIOS found the hard drive in the BIOS, the last found is due to hard disk failure caused the computer Boot card logo. This motherboard requires a hard drive test to pass the self-test. The Rising Sun 125f/Zhaoyang e280s Motherboard uses the SIS chipset, this motherboard if does not connect the hard disk test will appear the boot card

) Second, the Assembly of the wall barrier car The first step, the car bottom, fasteners, the code plate of the yellow protective paper torn off, and then the fastener into the car floor. The second step is to install the code tray and secure the motor to the baseplate. The large side of the plate axis is small and the large side is inserted into the motor shaft (note: The motor leads the copper sheet toward the inside, that is, one end of the code tray). In the third step, insert th

Assembling Peripheral EquipmentThere are parts that are not able to use automatic equipment such as reflow soldering machines and need to be handled manually. Figure 18 shows the manual soldering of the handset microphone on the motherboard. Some parts do not need welding, manual assembly, or screw. Figure 19, assemble the mobile ph

easy to install and the installation screws are shielded. The installation screws are more concise and bright in appearance, and can work closely with each other even after multiple disassembly and removal;4) colorful: The Panel can be selected in multiple colors to meet the indoor decoration requirements for various occasions and environments. Currently, the vast majority of well-known wiring product supp

amplifier circuit of the speaker, no signs of exceptions in the circuit, capacitor resistance and other components. After the power supply is switched on, it is found that in addition to the power amplifier Integrated Block is particularly hot, the bridge is also very hot, and the initial judgment is that the power amplifier Integrated Block is likely to be damaged. Replace the bridge and remove the soldering tin on the four pins of the bridge with a soldering iron and a tin-absorbing device. A

Recently, Hewlett-Packard (HP) in Japan has launched a small server "HP ProLiant MicroServer" or "MicroServer". This is a small server designed for companies and individual users.In any case, the minimum configuration of 35700 yen is about 2945 yuan.) The price is attractive. In fact, the small server size is also one of the reasons for low prices.(Recommended for BKJIA: Top 10 mainstream Nehalem servers (Multi-Chart )). Let's take a look at the specific features of this server: Small Size, la

transmission in the LAN, and complies with the IEEE 10Base-T standard. 5th twisted pair wires currently have the largest LAN market, with a maximum rate of 100 Mbps, in line with the IEEE 3u 100Base-TX standard. The main difference between Category 5 and Category 5 is the application. Only two pairs of cables are used for transmission during use of Category 5 cables. Category 5 uses four pairs of full duplex transmission to meet Gigabit Ethernet applications. Category 5 has higher performance r

. Dependency (Dependency)DependencyFor two relatively independent objects, when one object is responsible for constructing an instance of another object, or a service that relies on another object, the two objects are primarily dependent.[Specific performance]Dependencies are represented in local variables, parameters of methods, and calls to static methods[Example of Reality]For example, if you are going to screw the screws, do you want to use (i.e.
