In this guide I explain how to disassemble a Dell Inspiron 1440 laptop.
All disassembly steps could be the same or very similar for some other Dell Inspiron 14 models.
Before you start, make sure it is turned off.
Remove the main battery.
Remove one screw (yellow) securing the DVD drive and pull the drive from the bottom case.
Remove tow screws (green) securing the hard drive and pull the hard drive out.
Remove one screw (red) securing the memory/wireless card cover and remove the cover.
Dell Inspiron 1440 has a SATA DVD drive installed.
It comes with a regular 2.5″ SATA hard drive. Any large 2.5″ SATA HDD should work fine in this computer.
Both memory modules can be accessed though the door on the bottom.
Dell Inspiron 1440 can take up to 8GB RAM max. You can install up to 4GB memory module into each slot.
You should use PC2-6400 DDR2 200pin SODIMM memory modules.
You remove the memory module in the following order:
1. Spread latches on both sides of the memory slot until the memory module pops up at a 30 degree angle.
2. Pull the memory module from the slot by the edges.
Remove one screw securing the wireless card.
Pull the wireless card from the slot.
When the wireless card removed, you can disconnect both antenna cables.
Simply grab the gold connector with your fingers and unsnap it from the wireless card.
In the next 8 steps I explain how to remove the keyboard.
If you just replacing the keyboard it’s not necessary to go though all previous steps.
Lift up the right side of the speaker cover with a sharp object.
Remove the speaker cover.
Remove two screws securing the keyboard on the top.
Lift up the top side of the keyboard as it shown on the picture below.
Now you can access the cable connector.
Before you pull the cable from the connector, you’ll have to unlock the connector.

Now you can pull the cable and remove the keyboard.
Remove seven screws from the bottom case.
Remove seven screws securing the top cover assembly.
Disconnect the power button cable, touchpad cable and video cable from the motherboard.
Here’s how to unlock connectors for the power button cable and touchpad cable.
Very carefully move the brown clip about 2 millimeters towards the LCD screen.
Do not separate the brown clip from the white base.
On the following picture the connector is shown in the unlocked position.
The brown clip still attached to the base but the connector unlocked.
Now you can pull the cable.
In order to disconnect the video cable simply lift up the connector by the blue tab.
Pull both wireless card antenna cable through the opening in the top cover.
Now I’m going to remove the top cover assembly.
You can separate the top cover assembly from the base with a guitar pick.
Insert the pick between the top cover and base and slowly move it along the side.

On the following picture you can see the bottom side of the top cover assembly.
Here’s laptop without top cover installed.
Now I’m going to remove the LCD screen assembly.
Disconnect the display cable.
Unroute the video cable, wireless antenna cables and display cable.
Remove two screws securing the hinges.
Carefully lift up the LCD assembly and separate it from the base.
After the screen assembly removed, you can take it apart and remove the screen. It shouldn’t be very difficult.
1. Separate the screen bezel from the cover with your fingers.
2. Remove all screws securing the screen.
3. Remove the screen and disconnect the video cable.

Now I”m going to remove the motherboard.
Disconnect the speaker cable from the motherboard.
Disconnect the USB board cable from the motherboard.
Remove three screw securing the motherboard to the base.
Lift up the left side of the motherboard.
Here’s the base picture with the motherboard removed.
Both speakers, daughter board and USB board still attached to the bottom case.
There is nothing to remove on this side of the motherboard. Let’s turn it over.
On the other side of the motherboard you can access the CMOS battery, cooling assembly (heatsink and fan) and processor.
In order to remove the cooling assembly you’ll have to unscrew five screws and disconnect the cooling fan cable from the motherboard.
After that you should be able to remove the cooling assembly.
By the way, in a Dell Inspiron 1440 the power jack is soldered to the motherboard.
