(A), market status

In 2004 the price of notebook computers can be said to record lows, and now no one says no, low cost notebook computer line lies. Who want to purchase the 2005 budget but not too well-off friends, may be most concerned about is the 2005 notebook to what extent can be cheaper.

Said to have been a domestic brand notebooks in 2005 to do 3999 yuan, but off in mid-2004 when it was ahead of evolve into a living reality. One wonders how such a cheap laptop now, and desktop fast running out, in the end when a tall cheap to you? To answer that question, we must (more…)

We can see the notebook market, the brand is more and more light there is more than a dozen well-known brand overseas, not to mention domestic, not too many brands, each brand has carved out for the market demand, many series, each series has carved out a large number of models, and really let – some new to notebook market, plan to buy a notebook endless friends difficult. Here some of the mainstream brands on the market to make a presentation to help you sort out our thinking, sure direction. (more…)

01) defragmenting the hard disk “failure”

Recently the use of Windows native defrag functions encounter a strange question, select the. Set by “analysis” button, it says “need to Defrag the hard disk” and then click the “order”, too – after the prompt “order complete”, but distribution of data on the hard disk does not happen any | any change (still very messy ), I cup defrag simply no doubt play a role, how is this going on, hard drive broken? Are there any other way to solve (more…)

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 temperature rises, as the CPU silicon transistor logic device leakage current will increase, this CPU as a direct result of unstable, life has become shorter, and easily damaged. CPU cooling therefore (more…)

CPU fault when we encounter the proper diagnosis of the nuclear deal with it?

And CPU-related failure was better judged. CPU problems, the general is unable to boot, the system no response, that is, press the power switch, chassis no Ren Heming horn sounds, the display without any display. If the above phenomena, we should suspect that this phenomenon may be related to the CPU. Thinking outside the processing CPU failures are as follows:

(1) CPU is burnt, crushed

Open the chassis inspection, remove the fan, check out CPU and CPU with the naked eye if there were burnt, crushed traces. Now using packaged (more…)

When we plug the memory what needs attention?

Some may think that there is nothing special about installing memory, but a lot of memory failures are due to irrational swappable memory due to the current mainstream DDR SDRAM, for example, when the first installation of the memory slots on both sides of the card Bankai Button, then observe the slot, you can find the middle of a protruding slot position. The pins on the memory also has a gap. Hold the memory ends, to align (more…)

When the computer fails, the fault detection is the first step to rule out hardware failure is the most important step. Although the causes of computer failures are numerous and diverse, as long as the master relevant skills, identify the causes of failure or rule-based.

Computer repair in the past, we must first clear failure of the specific phenomenon of computer-generated, so as to accuracy, clarity to determine the causes of computer-generated. Computer failure, manifests itself in crashes, blue, black, Huaping, automatic restart, unable to (more…)

In the course of computer failure is inevitable, I do. Typically, these failures are the more simple failure to understand the phenomenon through the fault. User can easily troubleshoot. Will also introduce the most common computer maintenance and routine maintenance methods, computer out to minimize the risk of failure.

When a computer failure, a first step into chaos square inch, the analysis on the fault occurred, such as memories of what was performed before failure occurs Naxie operation; produce what is more the fault phenomena; then the phenomenon of these failures to determine the causes of (more…)

As wireless communications, wireless networks worldwide and the rapid application of a wide range of fields, with high technology and military and civilian needs, has been the rapid development of microwave technology. Microwave industry and supporting the rapid development of academic activities is also very active, electromagnetic theory and microwave technology are also new challenges in further development.
