An Apple MacBook Air laptop was booked in with keyboard problem.
Owner of the laptop spilled water
onto the keyboard of the Mac, since then the keyboard didn’t work properly.
Random letters came up when typing. The laptop booted up straight into
Safe Boot as if Shift key was engaged.
On this Apple MacBook Air, its
keyboard unit is integrated into its aluminium casing. The keyboard is
connected to touchpad unit, and touchpad unit is, via a ribbon cable, connected
to logic board. Thus the problem may lie within any of these units. Replacing
the keyboard unit does NOT guarantee to fix the problem. We have come across a
different job (same Apple MacBook Air that had water spilt on) that had the
same problem but due to both damaged keyboard and touchpad (demonstrated in
another post).
The Repairs:
Using available spare parts and a
number of tests, we have determined that the laptop keyboard needs to be
replaced.
Let’s first have a look at its
bottom cover.
Battery need to be disconnected to
stop power going in to the laptop, so let’s take the battery out from the
laptop.
There we’ll see logic board, fan and
other parts. All these parts need to be removed before keyboard can be taken
out.
Take extra precaution here because
these electronic parts are sensitive, any “minor” accidental damages
can cause great damages to the computer.
Once fan, logic board, wireless
adaptor etc are removed from the laptop, we should have the below (speakers not
yet removed).
Now let’s take out a same keyboard
(integrated in aluminum case).
Different MacBook Air has different
keyboard, make sure the part is compatible otherwise it will not fit and will
not work.
Now we need to remove the keyboard
and bottom casing from the laptop’s display panel. The job is simpler from
here. Let’s put in the new keyboard, connect it to the display panel,
reassemble the laptop and test it out.
The laptop starts up fine, open
TextEdit and check every key.
All the keys are now working as they
should. Another Apple MacBook Air laptop fixed successfully.
