Power is like the heart of a computer, which plays a key role in stabilizing the power supply. As long as the power supply plug in, there will be work, even if not on, the internal standby pow
Assemble the computer process of the friend will tend to the power of the cold, like to focus attention to the processor (CPU) and independent graphics, memory and other major computer components, and often on the power is not how to care, which is the most easily in the power
1, the hard disk appears bad track. Bad power is easy to cause the hard drive to appear false bad, this kind of fault can be repaired by software generally. In such cases, first check the power supply. If the problem is confirmed to be a power supply, the new
Chassis power supply as a source of computer energy, its importance is more and more people pay attention to, but, the importance of power supply fan is still neglected by most consumers. As a result, a sudden increase in the noise of the
When you buy a computer power supply, be sure to pay attention to the following six power supply parameters, which can choose a high-quality power is very helpful oh ~
One, the weight of the
The current production of computer motherboards are using switching power supply mode. Switching power supply mode can be divided into: single-phase power supply, two-phase
Computer malfunction: Computer Configuration: abit 865PE motherboard, P4 2.4CCPU, two Kingston 256M DDR400 memory, Dylan constant into X700 video card, 250W power supply. In recent weeks, frequent video card failure, in the normal operation of a sudden black screen, and then the boot BIOS has a long two short sound ala
The cause analysis and solution of the power supply light of notebook computer is not bright/flashing continuously
One, the power light is not bright
First of all, The notebook power light is not lit, there are two situations:
If the LEDs on the external
plan for the video card is "Maximum battery life", the processor is thermally passive, the minimum processor state is "0%", the maximum processor state is "100%", and the screen brightness is 40% when the battery is switched on, and the power supply is 100%. Energy-saving mode is more suitable for mobile office use, all hardware in the state of the lowest power
note Aspects 1. Regularly dust the Power box. The Power box is the most dusty parts, but also regularly add lubricating oil to the computer fan to avoid the fan to produce a lot of noise, the health of people is not good.
Note Aspects 2. Recommended to buy a computer when choosing a good quality
With the popularity of Windows 8, a notebook that installs Windows 8 after a shutdown action, the power supply, and so on, will be lit for 10 seconds or even minutes after the screen is closed. This behavior is actually due to the mixed shutdown characteristics of Windows 8 and is not a fault.
Reason Analysis:
On Windows 8 Systems, Microsoft has introduced a new hybrid shutdown model to achieve faster s
Computer host a power to automatically start the boot, do not press the host to start the button.
The reason for the appearance
1. Power plug can not guarantee a good contact
2. Computer Power problem
3.bios Setup Issues
Solving method
1. Repair Plug
2. Replace the
installed by default, you may not find the sleep or Hibernate options on the computer's shutdown menu. If you are using a power supply that supports both features, right-click the Start menu and choose Power Options. Go to the Select Power Button Feature tab, and then click Change settings that are not currently avail
efficiency is low, and a large heat sink needs to be installed.This type of power supply is not suitable for computer and other equipment, and will be gradually replaced by the switch power supply.
Ii. Principle of switching power
: the main characteristic of linear power supply is that the power device is working in the amplification State, which has the advantages of high stability, good reliability and low cost, but is inefficient, bulky, and bulky. Only medium and small power supply can be impleme
My motherboard is a 24PIN power interface, the power is 20PIN interface, compared, the more out of the interface is (+12V, +5v) and (+3.3v, GND) Two groups, now the motherboard only one +3.3v output used in the SATA power sockets, Want to use a large 4-pin socket to transfer into the 4-pin motherboard power connector,
the power output without shutting down the power supply;
5. Constant Voltage Constant Current: the output Constant Voltage Constant Current automatically switches, and the voltage and current values are continuously adjusted linearly;
6. Protection Functions: overvoltage protection, overcurrent protection, over-temperature protection, and overload protection;
7.
power supply is insufficient, one has the air-conditioner to start the computer to restart. This phenomenon has been bothering me for some time. Their ups can not be used normally: battery power when the CRT monitor was opened by others caused degaussing coil suddenly open recoil high-voltage damage inverter mos tube,
In the past, when purchasing computer accessories, the power supply was one of the most easily overlooked components. However, its various voltage output specifications, voltage stability, and protection in case of exceptions were very important, because the power required for all the accessories in the host must be su
The basic function of the power supply in the computer is to convert 220V alternating current into the low-voltage DC power required by the computer, generally it is difficult to see the effect on the performance of the whole machine intuitively. But as a source of
