Liquid Damage Repairs:
Not all liquids are the same. Pure filtered and Deionized Water are not conductive. It's only when salts get into the mix would your notebook have problems with shorted components and traces. Salts that dissolve in water break into positively and negatively charged ions. Conductivity is the ability of water to conduct an electrical current, and the dissolved ions are the conductors.
So it depends what you spill onto your notebook. Salty waters such as soups, tea, cat pee (yes, it happens) are the most difficult to repair, because components on the logic board becomes shorted and damaged. This is where we prevail because we have the experience and schematics of your notebooks to do on-board, component level repairs.
Other liquids such as water and coffee damage are less severe to the logic board. If the power source (battery or AC adapter) was removed right after the accident, the damages will be minimal and may work after a simple cleaning and drying process. However, problems arise when the battery or AC adapter stays connected and the current is still passing through components, this causes oxidation of the components as oxygen in the water reacts with metals in the components. This causes the leads of some components to become non conductive.
Whatever the reasons, we are your best bet to fixing your Apple Products. Since Apple doesn’t do squat for you once a drop of liquid touches your laptop. (Aside from replacing your logic board) You can be assured that we are the right Technicians to repair your notebook.
