So its chassis does not have an IP address,

Since 05, SUV sales have grown steadily, and by the end of last year domestic SUVs accounted for the second largest car rankings. Modern to the SUV pro-gaze, then at home and abroad major automakers are competing in the fierce competition in the Chinese market, how to choose a suitable car? Learn the following points, absolutely enough!First of all, the selection of SUVs has to look at four important basic information.　　See Fuel consumptionBefore you buy a car, consider the cost of raising a car

Visitor-Visitor ModePurposeWithout changing the classes in a hierarchy, define new operations that act on each element of the class.CaseThere are different device Equipment, such as Chassis and FloppyDisk. Some people want to know its performance, but some want to know its price, and some may want to know other information, such as manufacturer and manufacturing materials. However, when an Equipment class is defined and a subclass is defined, you need

motherboard temperature is too high reason and solution: 50 more normal, games, etc. in 60, or even 70 degrees (occasionally), generally more than fifty or sixty degrees that should take measures to dissipate heat. 1. Your motherboard temperature monitoring failure (sensor damage) caused, the temperature does not change. 2. Your host box internal cooling performance is too poor, fan aging and other factors caused. 3.CPU model problem: If the processor for Pentium D, especially the Pentium D8

, if the type of software often run in summer does not have a good fan sound high temperature must be normal. The main way to dissipate heat is by increasing the motherboard heatsink and chassis fan. Additional motherboard temperature high reason and solution: Cause the motherboard temperature is too high for the following reasons: 1, inside the chassis and the mother

, Serial ATA due to the use of point-to-point way to transmit data, so only need 4 lines to complete the send and receive function, plus the other three ground, a total of only 7 physical connection to meet the needs of data transmission. Due to the low transmission data lines, SATA in the physical circuit of the electrical performance of the interference greatly reduced, which also ensures the future disk transmission rate further upgrade.Compared to parallel ATA, the data cable of Serial ATA i

graphics is necessary, in addition to today many CPUs are built into the core graphics card, if there is no large game requirements, rely on the CPU built-in core graphics can meet the You don't need to match a standalone video card. In layman's parlance, the video card is equivalent to the human eye, without which the computer will not be able to drive the display screen. Memory: Memory belongs to the CPU and other hardware communication bridge, decide how many programs can run at the same ti

Large-screen LCD TVs are already very popular in the family, however, only to watch TV, and there is no big entertainment, first of all, can not play online games, the other TV movies and TV programs are not rich in the network, so many home users will be matching a HTPC host to meet the network rich audio-visual and game entertainment needs, The combination of Super large screen LCD display, entertaining is very good. For everyone to recommend a balanced performance and fashion appearance of th

drive problem If the optical drive is damaged internally, it can also cause the host to start slowly or fail the self-test, or it may suddenly restart during operation. In the latter case, if we replace the optical drive after the appearance, it is likely that the optical drive power consumption caused by different. What you need to understand is that although the ATPI interface of the optical drive is the same, but different manufacturers of the PIN definition is not the same, if we have a pr

Label: State port so the network cannot switch port status multipleVSS uses the inter-chassis nsf/sso as the primary high-availability mechanism between the two enclosures. One Virtual Switch member chassis will be a member of the primary virtual switch, and another member will be in the hot wait state of the control Panel. The data panels for both enclosures are available, so the total traffic forwarding c

reason is that your motherboard design or BIOS has some bugs, because the ATX power supply, plug plus, the power has already started to work, and so you press the key, the motherboard because it is not able to provide the necessary power on the instant voltage, resulting in the first boot failure. Reference to the solution: first to change the power of a large high-quality power, if it does not work, you can refresh the BIOS, no longer work, you can only try to shut down every time, unplug the

the button on the chassis is not easy to bounce, it appears in use because of occasional touch of the chassis or a sudden reboot of the host in the normal use state. Therefore, when the reset switch can not be moved freely, we must carefully check, it is best to replace the new reset button switch or the external button of the chassis lubrication treatment. The

self-test. However, when the reset switch is less flexible or the button on the chassis is not easy to bounce, it appears in use because of occasional touch of the chassis or a sudden reboot of the host in the normal use state. Therefore, when the reset switch can not be moved freely, we must carefully check, it is best to replace the new reset button switch or the external button of the

oxidation caused by poor contact, you can have the hardness of the White Paper folded (surface smooth that facing outside), insert the groove to wipe back and forth. In addition, the CPU slot used to detect the CPU temperature or the motherboard used to monitor the temperature of the chassis in the thermal resistor attached to the dust, it is likely to cause the motherboard to the temperature identification error, which causes the motherboard protec

motherboard temperature is too high solution: Cause the motherboard temperature is too high for the following reasons: 1, inside the chassis and the motherboard dust more. 2, check the chassis ventilation channel is not smooth and the fan running slowly. 3, Motherboard North Bridge Radiator is not strong, the North bridge temperature will lead to high temperature board. 4. Run multiple prog

your hard drive die. Solution: Shut down after something has forgotten to do, also put down his; must be completed, please wait more than a minute to reboot, or the machine does not disconnect the power when the chassis to press the hot boot key. If you can't do all the above, for the sake of your love machine health, I suggest you fasten a rope on the computer desk so that you can tie your hand for more than a minute. 5, the Boot box lid operation

current performance of single cards to improve the plight of the weak, through the dual-SIM work to improve the overall performance. For enthusiasts who need extreme performance, top cards are no longer enough to meet their needs, and the two top cards are his choice. Conclusion: According to the choice of their own needs, low-end users do not recommend the choice of dual-card platform, recommended high-end users using dual-SIM platform to provide speed performance. Keyboard mouse,

Ah's very affectionate, but your mind must keep calm, the brain one heat hundreds of RMB to slip into the other people's purses in vain now the line of the normal profit of a machine is probably in 200RMB or so. Buying, it's a process of brain Let me choose the ordinary Celeron grade as an example, in accordance with the order of purchase orders of accessories one by one and sell the Lady contest it! CPU: Celeron 2.4 No more nonsense, CPU price is the most transparent in the line Motherboar

Failure phenomenon: Phenomenon 1: After the boot, the monitor is dark, the chassis issued "beep-, beep-" long sound. Phenomenon 2: After the boot, the monitor interface stays in the boot screen (can not enter the system desktop), and constantly restart. Phenomenon 3: After the boot, the monitor is dark (the monitor is good), the chassis in addition to the fan rotation there is no other sound. Failure re
