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.

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.

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.

The assembly line problem is as follows:Colonel Motor Company produces cars in factories with two assembly lines, and a chassis that enters each assembly line will have different parts installed on the chassis of the vehicle at each station, and the final finished car leaves from the end of the assembly line. As shown in the following figure.

Through the fault surface, after a lot of analysis, finally determined that the CPU is poor heat dissipation, resulting in the CPU overheating protection function open and frequent restart. The author's computer configuration is the Intel Pentium 4 630 processor, 1GB ddr2-667 memory, gigabyte 945P-G motherboard, 160GB SATA hard drive, Rainbow 6600GT graphics card, configuration can be said to be the mainstream. But after running for just
Follow the performance competitions of several Cisco smart switches. Many companies now have their own switches to learn about the performance of Cisco smart switches and provide objective references for your selection, select a Cisco smart switch that suits your company.
Cisco is the only company in the enterprise, service provider, and commercial SMB that provides a comprehensive range of LAN switching solutions for all core and edge branches in the customer field. Cisco is the only company th
some faults. It is best to use exclusion to quickly determine the fault location.
8. Optical Drive Problems
If the internal drive is damaged, the host may be slow to start or cannot pass self-check, or it may be restarted suddenly during work. For the latter case, if we change the optical drive, it is likely that the power consumption of the optical drive is different. Although the atpi interfaces of the optical drive are the same, the pin definitions of different manufacturers are differen
For the majority of computer users, CPU cooling is a top priority, whether it is the CPU produced by Intel or AMD, cooling the CPU is very important.
Mainstream processors consume a lot of power and generate high heat. In this way, the CPU cooling requirements are more stringent. With the launch of the more powerful Pentium 4 processor, Intel has updated its requirements for the CPU cooling environment necessary for the system. One of the requirements is to describe the limit value of CPU core t
use of a certain brand of optical drive, but it will not work for other brands of optical drive, which requires attention.
9. The reset key quality is incorrect.
If the reset switch is damaged and the internal Reed is always in the transient position, the host cannot perform self-check. However, when the reset switch is elastically weakened or the button on the chassis is not easily loaded, it will appear during use, the host suddenly restarts be
Lien0000342014-10-061. Problem Description
A car factory has two assembly lines, each of which has n assembly stations. The assembly station J of assembly line I is represented as Si, J, and the Assembly time of the station is Ai, J. An automobile chassis enters the factory, and then enters the assembly line I (I is 1 or 2), which takes the time of EI. After passing through the J assembly station of a line, the ch
confirm whether the CPU cooling is normal. Enable the chassis to visually check whether the fan blade works normally, and then enter the BIOS option to check the fan speed and CPU operating temperature. If a fan problem is found, perform related Dust Removal maintenance on the fan or change the fan with better quality. If you want to eliminate the hardware cause, go to the system and choose "kiss to death" from the installation disc to overwrite the
industrial control, meet the needs of users at different levels for testing, measurement, data collection and industrial automation without sacrificing measurement indicators and increasing development costs.

better scalability, we can consider the factory model. Different products are assembled with different implementation factories.
Typical applications
To illustrate the advantages of the factory model, there may be no more suitable example than assembling a car. The scenario is as follows: a car consists of an engine, a wheel, and a chassis. Now a car needs to be assembled and handed over to the caller. If the factory mode is not used, the Code is as
