STEP 1

First of all, make sure the laptop is powered off.

Unlock and remove the battery.

STEP 2

You'll find two covers on the bottom of the laptop - the memory cover and hard drive cover.

Loosen screws securing both covers. Lift up and remove both covers.

STEP 3

Slide the hard drive to the left to disconnect it from the motherboard.

Lift up and remove the hard drive.

My Toshiba Satellite P755 laptop had a regular 2.5" SATA hard drive removed. This drive can be easily replaced with a larger capacity drive or SSD.

STEP 4

Both memory slots/modules can be accessed on the bottom of the laptop.

I'll leave both memory modules connected because it's not necessary to remove them for the purpose of my guide.

STEP 5

Remove one screw securing the DVD drive on the bottom of the laptop.

Pull the DVD drive from the laptop and remove it.

STEP 6

Remove two screws securing the keyboard.

STEP 7

Insert a piece of soft plastic between the keyboard and top cover and carefully lift up the keyboard.

I'm using the guitar pick for that.

After the top side of the keyboard lifted up you can continue removing it with your fingers.

STEP 8

Lift up the top side of the keyboard as it shown on the picture.

STEP 9

Move the keyboard towards the screen so you can access cable connectors located under the keyboard.

There are two cables: data cable and backlight cable.

In the following two steps I show how to unlock both connectors and release cables.

STEP 10

Each connector has a locking tab (moving part).

Slide the locking tab about 1-2 millimeters toward the display. Doing this will release the cable.

NOTE: the locking tab must stay attached to the connector base.

STEP 11

On this picture both connectors shown in the unlocked position.

Now you can pull cables from both connectors.

STEP 12

Lift up and remove the keyboard.

STEP 13

Now remove all screws from the bottom of the laptop.

STEP 14

Remove two screws securing the top cover assembly.

Disconnect the following cables:
1. Touchpad cable.
2. Speaker cable.
3. Media control board cable.

STEP 15

Connectors 1 and 3 do not have locking tab. You grab the cable by the blue tab and pull it from the connector.

The speaker connector 2 is a regular male-female type. Unplug the connector with your fingernails.

STEP 16

Start separating the top cover assembly from the bottom cover.

STEP 17

If the top cover doesn't want to separate you can use a piece of soft plastic.

Insert it between the top cover and bottom case and slowly move along the side.

Continue removing the top cover with your fingers.

STEP 18

The top cover assembly removed.

STEP 19

On the bottom side of the top cover you can access the following components:
- Media control board.
- Both speakers.
- Touchpad.

STEP 20

When the top cover removed, it gives you access to following main laptop components:
- Power button board.
- Cooling fan.
- Wireless card.
- DC jack harness.
- Motherboard.

STEP 21

The cooling fan can be removed without removing the motherboard.

Disconnect the fan cable from the motherboard.

Remove two screws securing the cooling fan to the bottom cover.

STEP 22

Lift up and remove the fan.

STEP 23

The power button located on a separate board which is connected to the motherboard.

You can disconnect the power button board cable using same technique as we used in steps 10-11.

STEP 24

In Toshiba Satellite P755/P750 laptop the DC power jack is attached to the cable.

In the next guides I explain how to remove the screen.
