CPU failure causes

CPU is very sophisticated and high tech products, how could it fail?

CPU have problems because the following areas:

(1) poor heat

CPU at work will generate a lot of heat, leading to its own CPU temperature. When the Read More…

Diagnosis and treatment of common hardware failure-2

6, drive Fault Diagnosis

Less likely to drive failure, the most common drive failure is mainly mechanical failure, followed by the circuit’s fault. And adjusted by the user of computer failures caused by improper fault than the fault components a lot more damage. Common types of drive failures are: Read More…

Hardware – array of diagnostic and treatment

Computer has a hardware failure of the main reasons and use of the environment, the user’s operation habits, hardware, natural aging and the poor quality hardware products such as Xiangguan in the ordinary case, so long as Cha Zhaochu cause of the failure of hardware equipment Bing Jiang Qi Geng Huan, Ji Ke rule out hardware failure.

Monitors: Computer’s face

Monitor your computer system’s “face”, this is a very vivid metaphor, as we know a person look at his external image as. So, your computer system’s “face” is to you “Clear the Air” then how can 7 make your computer more “face” mean?

Looking at the market displays, in the direction of technological development is toward large-screen, high definition, environmental protection energy conservation, low radiation, easy to control, flat screen, LED LCD, and other short-necked go in the direction; To achieve these Read More…

Zhongguancun “farmers market” in the DIYer

A few years ago, in the IT session, DIY can be a very popular word, DIY Do It Yourself is short, that means DIY. It is just the beginning of the field in IT, DIY assemble their own computer, DIYer who is assembling a computer.

We introduced earlier, the computer is composed of many parts, more or less in between these parts there were all kinds of relations, such as interfaces to be consistent, Sudu to coordination, and if the parts properly selected, not only affect your computer’s Read More…

Molten salt electrolyte batteries

In principle, the two electrodes in the electrolyte, as long as the potential difference can be formed cells, regardless of how the potential difference is formed. Formed by the molten salt electrolyte batteries, the battery electromotive force of the initial use of molten salt electrochemical system for the study of various thermodynamic properties offer great convenience and has a very Read More…

Shell material lead-acid batteries

Move over the past lead-acid batteries used with a hard rubber tanks (individual countries have been used because of the lack of asphalt rubber, plastic tank>, fixed-capacity battery and more small and medium sized glass tank while large capacity lead-lined Mu Cao. Of the 20th century, after 60 years, plastic rapid Read More…

Open circuit voltage of the battery

Does not discharge the battery in open circuit state, the battery potential difference between the two poles is called the open circuit voltage, generally available high-voltage meter and multimeter resistance measurement. Read More…

Characteristics of solar batteries

Solar cell theory and the model more or traditional batteries. New solar cell characteristics of the general theory and theory of reference from these mature, so in this section describes characteristics of solar batteries to conventional Read More…
