All repairs start here.
Opening up the MacBook Pro...
The first step to opening the MacBook Pro
as with most Apple laptops is flipping it over and
removing the battery. It is always wise to remove the battery during any repair. It is best to
remove any possible electricity that could damage the components inside. If you have an antistatic wristband, that will reduce your chances
of accidentally damaging your MacBook Pro.
To remove the battery, you should notice
two switches near the middle of the bottom
case. You will need to slide both of these
switches towards the back of the machine. You
should notice a red colored bottom underneath
if they are being slid the correct way. Once they
are both pushed back, the battery should pop
out. Just grab the battery and remove it from
the bay. Place it aside and be careful not to
scratch the casing on it.
After removing the battery, you should be
able to see the bottom side of the track-pad as
well as reveal five screws. Three of the screws
marked in the middle in the picture above are for
the memory bay cover. These screws are going
to have large polished heads and be very short.
These are the only three like this you will see on
the MacBook Pro so make sure you keep track
of them and remember where they go. Removing the battery should also reveal two screws on

side as the latch of the unit. These two screws
help hold the top case in place. There are also
the four long polished phillips head screws lining
the back of the bottom case marked above.

Once removed, you can proceed to take off

Removing the Top Case...
There are several more screws that hold
on the top case including the two you have already removed from the battery bay. The left
and right side have four screws each, and the
rear has two screws. (You can see these in the
images to the left.) All of these screws have the
polished heads which denote being external
screws. It is best to group these in a separate
pile in order to insure you do not confuse them
with any of the internal screws. Some of these
screws may work inside somewhere, but when
you get near the end of the repair and only have
the ugly screws remaining you will want to go
back in.

Keycap vs. Keyboard Issues
The keyboard on a laptop gets a lot of punishment over the years. With the use, exposure, and convenience for accidents, the keyboard can get
a lot of damage. If a key stops working, don’t jump to the conclusion that you just ruined your keyboard. You may just need a new key which we sell
at our online store.
If the character on your key has worn off, or your key has popped off and you can’t get it back on, most likely you just need to replace the keycap
and scissor mechanism. This will save you a lot of money over having to buy a full keyboard. The procedure for replacing the key is fairly simple, and
we offer a small manual on how to replace keys on our website.
Usually with spills, the keyboard is going to be affected as a whole. If several keys in a certain region stop working, or there is no response at all,
most likely the entire keyboard will need to be replaced.

There are five primary cables that go up into the display. They, therefore, need to be disconnected in order to separate the display from the

on the opposite side. They are very susceptible to any water damage that
trickles into the LCD, so be extra careful when cleaning your display.
To remove the inverter board, you simply just have to pull up on the
side connected to the LCD. Disconnect that cable, then pull the inverter
board out and disconnect the inverter cable. Once the board is out, you
can simple reconnect the two cables and reseat the inverter board safely
into its crevice. Be sure that the wires are routed well and not susceptible
to be cut or pinched once we snap the back display cover back on.
A typical symptom of a bad inverter board is when the backlight
never comes on at all or it briefly blinks only when powering up.

One of the most common repairs to a
MacBook Pro will be replacing the LCD after an
unlucky fall that cracks the display. This is fairly
easy to diagnose. The display will have cracks
on it and what looks like black ink seeping
through. This is actually the liquid crystal that is
now pressing up against the outside pane of
glass. There is no fix once it is broken. You will
have to replace the LCD and they are usually
quite expensive.
Once you have the back display casing off,
you should have a good view at the back of the
LCD. Be aware that the LCD does not include
the cables or the casing. It is a separate part.
The first thing you will notice on the back of the
LCD is the display cable as pictured on the first
vertical position so the cable can be removed.
The cable itself is held on by a light adhesive.

back and forth to loosen the adhesive and get a
flat tool to help detach it from the bezel. Once
