laptop computer repair


A first Compaq Laptop Battery investigation, after the familiar

Maintenance, we must first understand the use of the computer failure occurred when the situation and the previous state of repair, the failure to understand the specific event of failure phenomena and the use of hardware and software environment in order to prescribe the right Laptop Battery medicine. In addition, the maintenance of their computer before the computer should be better understanding of their hardware and software configuration and have useful life, etc., a definite purpose.

Second, opportunities, in the later machine

For the host or display does not appear fault light notebook computer Compaq Presario 1700 Battery, etc. should first check the laptop power supply part of the external parts, especially the machines outside some of the switches, sockets whether the open circuit, short circuit phenomena, do not think that these are not crucial for the small office Practice has proved that many users of computer failures are the result from the problems. When a confirmed normal external parts, and then other testing.

3, first mechanical, electrical, after

As the notebook is equipped with the Compaq Presario 900 Battery particularity required for the assembly of various components is very fine, improper installation can cause many problems, so first check whether the assembly of mechanical failure and then check whether the electrical failure was the general principles of maintenance of computers.

4, first the software after the hardware

First fix bugs and then ruled out hardware problems, this is an important principle in computer Compaq Presario 700 Battery repair. During maintenance work should pay attention to the user's software environment and our standard of What's the difference, is not what the industry recognized the use of non-compliant software, the system starts with no problem, we must first rule out software problems and then proceed to hardware maintenance. Such as the WINDOWS system software is damaged or missing may result in crash failures arise, since the system boot is a step by step process, which can not be a part of the error, if there is damage to the implementation of the file or the driver, the system will be dead in the这里. But the computer itself, the various components of the problem, the interface connectors poor contact problems, hardware problems, such as setting BIOS, the driver is perfect, and system compatibility, hardware, the stability of power supply equipment, as well as between the components the compatibility of anti-interference, and so the outside world may also lead to the production of computer hardware crash failures. We should start with the maintenance of software and then proceed to consider the Compaq Presario 1800 Battery hardware.

5, first cleaning, post-repair

If you have already opened her notebook computer, notebook computer checking the internal components, they would first focus on to see if the machine is clean, if we find the machine each component, lead, walking between the lines and finger dust, dirt, spider's web, or excess solder , welding oil, should be removed, a further overhaul, both to the reduction of natural failures, but also to achieve a multiplier effect. Practice shows that many problems are caused because of Compaq Presario 1200 Battery dirty, and a failure by the cleaning will often go away.

6, first power supply, after the machine

Power is the heart of notebook computers and accessories, if the power is not normal, we can not ensure the normal operation of other parts, there can be no check other failures. If you encounter without electricity and power failures related to fault detection of power supply should first consider the correctness of, including the battery whether there is electricity, if the external power adapter, to test socket is intact, the power adapter Compaq EVO N620C Battery output voltage and current whether it is the requirements of this model notebook computers and power DC panel are normal.

7, first common problem, after a special

According to the common characteristics of notebook computer failures and the failure of the various machine types unique to the phenomenon, first rule out the universality and the regularity with common faults, and then go check the specific Compaq EVO N610C Battery failure, in order to gradually narrow the scope of failure, from surface to the point, shorten repair time.

8, first the external, after the internal

As the laptop itself in the particularity of disassembly may be different models in the same part of the difficulty of dismantling the difference is very large, therefore, we maintain flexibility in the use of time to not blindly stick to conventions in the detection of the time from the simple easy to check the parts begin to solve the problem based on ideas, flexible use, better for Compaq EVO N600C Battery customer service.
