Any laptop or personal computer is not an indivisible device, but consists of various functional units. Sometimes the example given in the analogy with the children's designer is quite acceptable.
Основой, соединяющей все составляющие воедино, is the motherboard, or motherboard. You can say that without it there is no computer. It is not difficult to guess that replacing the motherboard is a relatively complicated operation that requires care and compliance with certain rules. However, with sufficient accuracy this work can produce any.
A person who is little familiar with computer technology,it may seem that replacing the motherboard is a rather rare operation. In fact, there are three main reasons for this:
- the need to replace the failed motherboard with a new one;
- the desire to gain access to additional settings;
- complete platform change.
Остановимся подробнее на каждом из указанных points. Being a sophisticated electronic product, the board includes capacitors. They come in several types: classic "kegs" with electrolyte inside and solid-state ones. The first have more capacity, but are cheaper at the same time, so some motherboard manufacturers use them. As a result, the cost of production can be significantly reduced. The only drawback of electrolytic capacitors is their short service life (in comparison with solid-state capacitors). Overpriced voltage, low-quality electrolyte, high ambient temperature, drying - all this can lead to the fact that the capacitors on the motherboard swell and cease to perform their functions. They can be replaced by restoring working capacity. But if the breakdown is repeated, then the replacement of the motherboard can solve the problem. Moreover, models with solid-state capacitors are more technological and lack these disadvantages (although their capacity is lower).
The next reason whyreplacement of the motherboard is required - these are new functions. Many CPUs allow an increase in their operating frequency, the so-called "overclocking", which can not be overlooked by application enthusiasts who are demanding the speed of mathematical calculations. Overclocking is also possible for memory modules. In addition, some processors contain inactive kernels, which can be activated by including the required option in the BIOS of the motherboard. If there are no options for enabling the required functions, and the accessories support them, then you have to resort to replacing the motherboard.
And the last reason is the decision to purchase a new processor, with which this fee can not work.
Replacement starts with a trip from the old motherboardall loops (both interface and power). Then, all the elements that prevent dismantling are removed from the housing. These can be expansion cards, power supplies. After unscrewing the fixing bolts, the motherboard can be removed. Next, we remove the cooling system and the processor itself. We take out the memory modules.
Installing the motherboard purchased forreplacement, is performed in the reverse order, starting with the CPU. The fixing bolts are screwed into special sleeves, thanks to which a gap is left between the board and the housing. Therefore, at first you should make sure that the screwed holes and holes of the new motherboard correspond. If this is not observed, then we rearrange them in the correct holes in the metal of the shell. Sometimes plastic clips are used instead of bolts, they must also be correctly set. After that, fix the board in the case. It is recommended that under the edges of the motherboard and memory slots, put a paper band (stitch) - this will prevent the inevitable bending during the connection. Connect all loops according to the instruction manual.
