The server power supply is frequently used by many friends at work. When the server power supply fails, it is very important to choose a new server power supply, because the server power supply is the "motive force" behind the stable operation of the server ". In the past, we introduced and paid much attention to energy-saving technologies on processors. Here we will mainly introduce the server power supply standards and what users should pay attention to when purchasing servers.
Two main power
Most servers are configured as 24-hour running devices. Therefore, server energy-saving technologies are more important than personal products such as PCs and laptops. Generally, there are two kinds of energy-saving technologies on servers. One is energy-saving technologies for processors, such as the Power Islands technology used by IBM on Power5, Intel's SpeedStep and AMD's PowerNow! The other is power supply optimization and management, such as Intel's Demand Based Switching technology.In the
microATX is the name of a computer board structure, also known as the mini ATX structure, which is a simplified version of the ATX structure.
Role
The main purpose of the Micro ATX specification is to reduce the overall cost of the PC system and to reduce the power requirements of the computer system.
Structural characteristics
The main features of the
connection switch needle after the computer still does not boot, it may be a power problem or motherboard circuit problems.5. Then simply test the power supply, disconnect the power connector on the motherboard and use tweezers to connect the black hole (preferably a wire hole) next to the Green Line of the motherboard power connector in the ATX power supply, to ground the Ps.on pins (that is, to start the ATX
Computer can not boot is a lot of friends have encountered problems, the general computer can not boot with the power and the motherboard power-on circuit, today we say that the computer can not boot troubleshooting methods and procedures:
Judge the power of a computer
First, the power supply, press the switch, if not power, and then unplug the main engine power, with tweezers to the Green Line and black lines short-circuit, look at the power supply fan does not, if the turn, indicating the po
called picocontainer. i'm starting here primarily because several of my colleagues at thoughtworks are very active in the development of picocontainer (yes, it's a sort of sort ate nepotism .)
Picocontainer uses a constructor to decide how to inject a finder implementation into the Lister class. For this to work, the movie Lister class needs to declare a constructor that has des everything it needs injected.
class MovieLister...public MovieLister(MovieFinder finder) {this.finder = finder;}

The EATX motherboard is an abbreviation for the extended ATX, primarily for rackmount server systems. It is typically used on servers that are not capable on dual processors and standard ATX motherboards, with 12x13 inches (305mmx330 mm) in size. Eatx the upper part of the motherboard has the same fixed screw position as ATX and is used for high-performance works
Will you start the system? "If I ask you such a question, it will surely lead to a lot of bad eggs. But now I want to ask, "Do you know how many boot methods are available? "Certainly not many people can answer the question completely. In addition to power supply, you can press the power switch on the host panel to start the instance. There are also eight ways to start the instance. If you don't believe it, follow the objective s845e motherboard used by the author to test it!First: timed boot is
experience and experience to work together to learn from each other, if there are errors or omissions or hope that we can give suggestions, I can learn knowledge from it.
Motherboard boot Failure Analysis and solution two:
One, the suspicion of host power supply or bad
First, the power supply, press the switch, if not power, and then unplug the main engine power, with tweezers to the Green Line and black lines short-circuit, look at the power supply fan does not, if the turn, indicating the
Solution for motherboard Power point is not lit:
1. Judge the computer power supply or bad
The 1th step, first connect the host power (ATX), press the host switch button, if not power, and then the power to connect the motherboard power plug off.
The 2nd step, using tweezers to power the green Line and black lines short-circuit, check to see the power supply fan does not turn. If the power supply fan turns, the power is good and the fault is in the

The motherboard has a board and a small board of points, even in the big slab, there are several models of the difference, here we do not elaborate, we need to know is that the different version of the motherboard in the PCB cost difference, while in the extended performance is also different, the final will affect the price of the motherboard and extended performance.

Summary: At present, how to realize the seamless Internet access of mobile users has become a hot topic in the field of communication, this paper firstly introduces the principle of two wireless access technologies based on Bluetooth technology, and discusses its routing technology briefly, and puts forward a simple solution for the handoff problem. Finally, several realization schemes of Pico Network in Bluetooth access network are given.

Unfortunately! A good-end machine finally fell down when I refreshed its BIOS for the nth time: not only is the BIOS data lost, but the bootblock is also damaged, the BIOS chip is soldered to the motherboard. All saving skills do not help. Final decision: deliver repair to the original manufacturer. It may take nearly a month to deliver repairs to the original manufacturer. Is there any use of my computer during this period? If you w
With the diversification trend of emerging technologies and application scenarios, VR is ushering in a new development period.The person who made this point was Pico's CEO, Zhou Hongwei.At the "Singularity and Innovator Summit" held in Shanghai on July 15, Zhou Hongwei the idea of "VR technology will help people and the scene to implement the application portal". In his understanding, "VR technology will bring great changes to the application of the industry", through the telepresence to restore

1. How to solve the computer boot without power
A newly installed computer, press the power button, the display does not show that the power LED is not lit, the computer can not start.
Check this type of failure should first check the connection problem, and then check the accessories good or bad, the specific steps are as follows:
First look at the monitor power led, found that the indicator light constantly flashing, indicating that the monitor power connection is normal, and

After compiling the new system kernel and module, we need to copy the new system kernel to the Linux startup directory. You can run the following command: "cp arch/i386/boot/bzImage/boot/vmlinuz-mykernel ". In addition, we also need to modify LILO so that LILO can find a new system kernel at system startup. We can use any text editing tool in Linux to modify the LILO configuration file. Here we use the pico text editor
Point-to-point and point-to-multipoint communication: Bluetooth devices can be composed of two networks in a specific way: Pico (Piconet) and distributed Networks (Scatternet), where the establishment of a Pico network begins with the connection of two devices, which can be composed of up to eight devices. In a pico net, only one master device (Master), the othe
