In this guide I show how to disassemble a Dell Inspiron 1764 laptop and access internal laptop components.
I’m taking it apart because this particular laptop started overheating and the cooling fan started making rattling noise.
I will disassemble the laptop, replace the processor cooling fan and clean up the heatsink.
As always, make sure the laptop is turned off before you start taking it apart.
Unlock and remove the laptop battery.
Unscrew three screws securing the service cover on the bottom of the laptop.
Lift up and remove the service cover.
Under the service cover you can access the following laptop components:
- Both memory modules.
- Hard drive.
- CMOS (RTC) battery.
- Wireless card.
Remove four screws securing the hard drive.
Slide the hard drive to the left to disconnect it from the motherboard.
Lift up and remove the hard drive.
Remove one screw securing the optical drive.
Slid the optical drive to the left to disconnect it from the motherboard.
Pull the optical drive and remove it from the laptop.
Remove two screw securing the keyboard bezel on the bottom of the laptop.
Start separating the keyboard bezel from the top cover.
You will have to wiggle the bezel to unlock hidden latches.
Be careful. The power button board attached to the keyboard bezel.
There is a cable connecting the power button board to the motherboard under the upper left corner of the bezel.
Lift up the bezel just enough to disconnect the cable from the motherboard.
In the following two steps I explain how to unlock the connector and release the cable.
Lift up the left side of the connector retainer (brown) with your fingernail.
The retainer will open up at a 90 degree angle.
On the following picture the same connector shown in the unlocked position.
Now you can pull the cable from the connector.
Continue separating the keyboard bezel from the top cover.
You can use a guitar pick to separate the bezel.
The keyboard bezel removed.
Remove four screws securing the keyboard.
Lift up the upper side of the keyboard.
Turn the keyboard upside down and place it on the palm rest.
Now you can access the keyboard cable connector.
It’s necessary to unlock the connector and release the cable before you remove the keyboard.
Lift up the left side of the connector retainer with your fingernail.
Pull the cable from the connector.
Now you can remove the keyboard.
Remove all shown screws from the bottom of the laptop.
Also, it is necessary to disconnect the antenna cables from the wireless card.
Disconnect both antenna cable from the wireless card.
Remove antenna cables from the guided path on the bottom of the laptop.
Pull wireless antenna cables though the opening in the top cover.
Remove cables from the guided path on the top cover.
Remove six screws securing the top cover.
Disconnect the trackpad cable from the motherboard.
Start separating the top cover from the laptop bottom case.
Continue removing the top cover.
The top cover removed from the laptop.
Here’s the bottom side of the top cover.
Here you can access the trackpad and trackpad button board.
After the top cover removed, you can access the cooling fan.
In Dell Inspiron 1764 laptop the fan can be removed and replaced without removing the motherboard.
Remove two screws securing the processor cooling fan.
Lift up the fan and disconnect the cable from the motherboard.
Now the failed cooling fan can be replaced with a new cooling fan.
When the fan is removed you can clean up the heat sink.
Look how much dust got stuck between the fan and heatsink.
That’s why my Dell Inspiron 1764 was running so hot.
