global Laptop and motherboard repair tutorial | Seite 40

When looking for signs of liquid damage, first you want to press down on all the keys of the
laptops keyboard, you are doing this to
feel for ―crispinessǁ or sticking keys. Since most liquid spills will occur over the keyboard, this is
the first place that will be affected. If a keyboard is saturated in liquid, and that liquid happens to
flow
through the protective plastic film under the keys, it can damage the digitizer contact pads of the
keyboard, it can also travel through the keyboard and down to the motherboard. Most people
will leave the battery in and can even leave the laptop plugged in after a spill occurs, but what they
don’t realize is that the electricity that is travelling through the laptop is continuing to cause damage to
all the areas that contain liquid. The liquid will dry eventually if
left untouched, though it will take a lot longer to dry if any liquid
leaked inside the laptops case and into the motherboard area. I have seen liquid spills 2 months old
that still had ―puddlesǁ of
liquid still residing on the motherboard and on the components.
This can occur under IC chips, under protective stickers that are placed on most motherboards, and
even in the open areas.
