A few things to know before you start taking your laptop apart

Electrostatic Discharge (ESD) can kill your computer

ESD can permanently damage your laptop. Always ware ESD wrist strap when you work with internal computer components.

How notebook screws are marked
Notebook screws

In Toshiba notebooks most screws are marked. Here are some examples:
F4 - flat-head screw 4mm long
B6 - button-head screw 6mm long
F16 - flat-head screw 16mm long
B8 - button-head screw 8mm long

When you are taking apart a laptop you'll have to deal with lots of screws. Keep everything organized.

 
Removing Memory Modules

Carefully spread latches on both sides of the memory slot with your fingers.

The memory module will pop up at 30 degrees angle. 

Carefully pull the memory module from the slot by the edges.

 
Removing Wireless Card

There are two antenna wires connected to the wireless card. 
White wire connects to the main connector on the card.
Black wire connects to the auxiliary connector on the card.

To disconnect the antenna wire from the wireless card grasp the connector with your fingers and unsnap it from the card.

Carefully spread latches on both sides of the wireless card slot, just enough to release the card.

The wireless card will pop up at 30 degrees angle.

Pull the wireless card from the slot by the edges.

 

 

Disconnecting Keyboard

Before you pull the keyboard cable from the connector on the motherboard, you'll have to open up the connector.

Unlock the cable by moving the connector lock (brown piece on this picture) up.

After the connector is unlocked you can pull the cable. Be very careful with the connector. If you accidentally damage the connector, you'll have to replace the motherboard.

 
If you accidentally damaged the keyboard connector, check out this connector repair guide.
 
Removing Modem Card

Usually the modem is secured to the motherboard by two screws. Remove them.

To disconnect the modem from the motherboard lift it up.

The connector is located under the modem and you cannot see it until the modem is remove. After the modem is removed, disconnect the cable (on the left side).
CPU came out attached to heatsink
In some cases, when you remove the heat sink, the CPU might get out attached to the heat sink. DO NOT install it back into the socket like that, separate the CPU from the heat sink first.

CPU came out attached to the heat sink because thermal paste dried out and glued the processor.

Insert a flathead screwdriver between the CPU and the heat sink surface. Carefully rotate the screwdriver until the CPU separates from the heat sink.

Lift up the CPU and install it back into the socket on the motherboard. Now you can safely remove old thermal paste and apply a new layer of paste.

 
Removing and Installing CPU

The CPU is locked in the socket. Before you can remove the CPU, you'll have to unlock the socket. Use a flathead screwdriver and turn the socket screw to "Open" position.

Lift up the CPU by the edges. Be careful, there are a lot of fragile pins on the opposite side of the CPU. You should be able to install the CPU back into the socket without any force.

There is only one correct way to install the processor into the socket. Both CPU and socket are keyed. When you are installing the CPU, make sure to match pins on the processor with holes on the socket.

Before applying thermal grease on the CPU, clean the surface with alcohol.

After the CPU surface is cleaned, apply a small drop of thermal grease.

Spread thermal grease evenly and install the heat sink.

ATTENTION! If you forget to lock the CPU in the socket, the laptop will not boot. If you install the heat sink without applying thermal grease, the CPU will overheat.
