Water, and especially tea, coffee, juice and other liquids, is an electricity conductor. And so, getting on a chip, they can cause multiple-circuit related to burnout and failure of various elements of circuit boards. These are the most obvious damages done by the water.

Besides this it is necessary to consider one more moment. Getting on the chip, which is energised, a liquid causes the electrolysis process, that is, in fact, the destructions of contact platforms. And therefore, if the moisture also has not caused short circuit, it can become the reason extensive damages of various circuit boards.
Most vulnerable to damage by the water are open board (motherboard- chips integrated on it, that is a video card, etc.) and the keyboard. The accessories having own case (a hard disk, drive DVD-ROM), fail much less often. However and they can suffer at laptop immersing in water.

Laptop water damage repair

Restoration of working capacity of the laptop at its damage by the water includes the whole complex of various actions. In the first place dismantling the computer and washing its. This necessary action, as many liquids (tea, coffee, juice etc.), drying up, leave a deposit which can appear the reason of short circuit of elements of a microcircuit. After that all boards is carefully dried up.

Next recovered laptop keyboard. If it is folding, then it'll cut exactly the same operation. Otherwise, need to be replaced by a new one.

The next step - checking of laptop parts and restore them if necessary. In some cases there can be sufficient a prosoldering of suspicious sites of a microcircuit and replacement of its damaged elements. In other cases full replacement of the failed microcircuit can be demanded.

On what success of repair depends
Success of repair of the laptop at hit in it liquids depends on several factors. The first of them - actions of the user. At hit of a liquid the owner of the computer should disconnect at once it from a network and necessarily remove the battery. Otherwise the battery even when the laptop will supply to the motherboard voltage required for power management scheme. And it can cause electrolysis and destruction pads chips. However, even prompt to remove the battery can not guarantee no damage, since the motherboard is another source of tension - the battery BIOS.

Also it is important, that the user did not include the laptop after a while, believing, that the liquid has already dried up. Even if this is true, the deposit which has remained on microcircuits can lead to multiple circuits between its elements.
Another very strongly influencing success of repair of the laptop the factor is the service centre in which the owner addresses. The matter is that repair can appear difficult enough. And therefore it is necessary, that it was carried out by the skilled professional specialising on restoration of laptops. Also, for good performance should be good equipment and the availability of opportunities to find a replacement for the failed motherboard. Therefore in the service centre there should be own warehouse of new accessories and extensive communications with suppliers of the computer equipment, capable to result any, even the most exotic microcircuit. It is undesirable contact those companies that are in the repair of laptops using second-hand motherboard, shot with malfunctioning computers, because of their potential unreliability.
