books on computer repair and maintenance

power outages, voltage instability and so on, the impact on the computer can not be slighted. ③, when the computer in the use of accidental power outages or crashes and system abnormal exit, should be the hard drive to scan maintenance, timely repair files or hard disk cluster errors. In this case, some files or clus

, blindly repair will not quickly grasp the motherboard maintenance methods. Therefore, to learn the circuit structure, working principle and signal flow, at the same time the actual computer motherboards, identify components, detection signal waveform and work voltage. Encounter the problem theory, and then practice, learn from other people's experience, only in

in the computer for the Damage Factor for different mm, of course, some bandits are not allowed, and some are not so accurate control of the time of the maintenance process is very important. Here are some time calculation methods for beginners: You can use ghost to install an XP system. Generally, it takes about 25 minutes (if you are familiar with it, it will take 20 minutes) to automatically install an

This period of time has been learning micro-marketing knowledge, the more learning can feel this thing powerful, yesterday in my mind suddenly flash, if the use of micro-marketing to do computer repair effect how? So this article was born. Now the computer repair stores are everywhere, an upscale community may have 3

I have been engaged in computer management and maintenance for a long time. I need to check and maintain computers frequently to ensure normal teaching work. For school computers, due to frequent use by students, some problems often occur. I have observed that there are not many hardware faults, even if most of the contact problems are caused by oxidation of gold fingers of dust or components, the problem c

things to do, is conducive to concentration of energy, conducive to fault diagnosis and positioning. It must be noted that after careful observation, it is necessary to judge and repair. Second, according to the observed phenomenon, to "first think and then do" first to do, including the following: First of all, think about how to do, from where to start, and then hands-on. It can be said that the first analysis of the judgement, and then

"killer" of computer hardware, however, due to the importance of not enough, more operational inertia and the existence of the lucky mind, often "illegal" hardware operations, so that "spark" gently flash, the computer's motherboard, memory, graphics and other components in a short moment on the "perish "Up. As static electricity is ubiquitous in our lives, it is very easy to accumulate a lot of static electricity when we touch and

into a comprehensive), such as the occurrence of abnormal situation can not handle the call for advice. Nine, for the computer memory has important data units and individuals, in addition to pay attention to the maintenance of software, but also should be equipped with UPS, in order to prevent power outages damaged computer hardware and software, in the area of

battery is not used for a long time, please charge and discharge at least two months to ensure its activity. 　　Maintenance of hard disk Either a desktop or a laptop's hard drive is a very delicate thing. Even though the hard drives are now super resistant, they should be prevented from shaking unnecessarily. Due to the notebook computer hard drive mobile problem, its seismic performance has been very goo

How to repair the computer motherboard First, the method of debugging: 1. Will suspect the chip, according to the manual instructions, first check the input, output is the signal (wave type), if there is no out, and then check the IC control signal (clock) and so on, if there is the possibility of this IC bad, no control signal, traced to its former pole until the damage to find the IC. 2. Find the tempo

the connection signal.1. Abnormal display colorImproper use or maintenance may lead to poor display. The problem of the video card and the display signal line should be ruled out first. In many cases, poor contact of the signal line will lead to the problem of the display color.Most of the time, it is likely that the display is magnetized. The CRT display will be magnetized by something with a strong magnetic field and lead to the problem of partial

Computer now has become a daily necessities of life, then how much do you know about computers? The following small series for you to organize some common computer hardware knowledge, quickly to learn! Computer hardware, including all the physical parts of a computer, to differentiate between the data it contains or e

First, the PE please enter the door As a maintenance system, we naturally hope that the more powerful the PE function, the better. For those computers that have been unable to access the system, we first need to download PE on other normal computers. We are downloading the old peaches made of the PE version, this is an Internet-ready PE. Step one: Prepare a bootable flash memory with a capacity of more than 128MB. Copy the required file Edit.com and

Niche a book, purchased in February 09, Samsung R458 Model, the year before the hands of the net to look at the graphic, their own demolition once, did not dismantle, the screen and the fuselage at the junction of the chassis dismantled. At that time always thought the official repair point maintenance assured, the final result is waiting for three days, spent more than 300 oceans, changed a rack.The above

How to use WinPE to repair a computer When the system fails, we should all use WinPE to fix it, so let's take a look at it now. Install a PE maintenance system on the hard disk first, select "Windows PE" in the Multiple boot menu when restarting the computer, the system will automatically load the necessary files and

then proceed with maintenance. Finally, in the process of analysis and judgment, according to their own knowledge, experience to make judgments, for their own do not know or do not understand, we must first to have experienced colleagues or your technical support engineers to consult and seek help. Third, in the majority of computer maintenance judgments, must
