It has been awhile since I actually disassembled a laptop or even written an article. Fortunately, when I was back in hometown for new year, my brother who trusted my ability to disassemble laptop had offered me the opportunity to clean his Dell Latitude E4300.
This guide will explain detailed step by step way on how to dismantle to clean a Dell Latitude E4300 notebook.
Advices taken here are taken at your own risk. AhWee.com will be held no responsibility if your laptop malfunction or lose your warranty.
NOTE: Even though Dell said disassembling laptop yourself would lose your warranty, but I haven’t void anybody’s warranty in any possible way yet.
Tools You Need For Dismantling and Cleaning
- Philips Screwdriver (Size #0 is great)
- Flat Blade Screwdriver (usually a test pen)
- A brush (about 1 inch or 2 cm wide would do it, not too big)
It pays to go to your nearest hardware store and get a well fit Phillips screwdriver because you don’t want to spoil the screws in your laptop.
Before You Start
Here are a few things you’ll need to do before you start to disassemble your Dell Latitude E4300.
- Clear your Table
Ensure that you have plenty of space (1 meter square would be great) to put all the components so they won’t go missing or falling off the table.
- Prepare a Small Container for Screws
Every single screws taken out from the laptop has their own job in keeping the computer intact. Don’t lose them.
- Disconnect all the Cables & Components
It’s wise to disconnect all usb cables, pendrives, power cords.
- Put Some Cloth or Thin Sponge Under the Laptop
To make sure that the rough table surface would not scratch your laptop.
- Remove the Battery
To remove the battery from your Dell Latitude E4300, unlock 2 of the latches and remove the battery out from the battery bay.
- Ground the Motherboard
When the battery is removed, simply ground the motherboard by pressing on the power button for a few seconds.
- Ground your Hands
Ground your hands by wearing a wrist grounding strap or touching an unpainted metal surface from time to time.
Step 1 : Remove The Harddisk
Always (I mean like every freaking time), remove the harddisk first and store it inside an antistatic bag if possible.
- Turn the laptop upside down. Note the harddisk is at the lower right hand corner.
- Unscrew two M3x3 screws.
- Slide the harddisk out from it’s compartment.
Step 2 : Remove The Hinge Cover
I like the hinge cover in E4300, very flexible (very easy to break too) and easy to remove.
- Note the indentation at the right side of the hinge cover, that’s the place where you start.
- Pry up the hinge cover using your test pen.
- Slowly lift up the whole thing from right to left.
Step 3 : Remove The Keyboard
After you remove the hinge cover, you can see three screws that secures the keyboard.
- Unscrew all the three M2x3 screws located at the top of the keyboard.
- Lift the keyboard up from the top, then slide the keyboard out.
- The connector is not a wire so it slides out together along with the keyboard.
Step 4 : Remove The LCD Screen
- Turn your laptop upside down, remove two M2.5×4 screws securing the display assembly on the white support.
- Remove two more M2.5×4 screws at the back of the laptop
- Turn the laptop rightside up and open the screen as far as possible.
- Remove the display cable with the blue tab.
- Remove 3 (white, grey, black) antennas that is labelled “Display”.
- Slowly lift the LCD screen out from its respective compartments.
Step 5 : Remove The Palm Rest
Note that this is the hardest part during a laptop disassembly. Be extra careful here to make sure every cable are dislodged and every screw is unscrewed before taking the palm rest apart.
- Turn the laptop upside down and remove the two M2.5×8 from the bottom of the computer and two M2x3 screws from the harddisk’s compartment.
Obviously, I forgot to remove the harddisk first, sorry.
- Turn the laptop rightside up, remove the five M2.5×8 screws and five M2.5×5 screws from the palm rest. The sizes are labelled beside each screw.
- Remove 6 cables that connects the palm rest to the motherboard.
- Start from the back of the laptop, slowly disengage every hooks until you have the whole palm rest out.
Step 6 : Remove The Dirty Fan
After the palm rest have been removed, you can see the system fan clearly.
- Disconnect the cable that connects the fan to the motherboard.
- Remove one M2.5×5 screw.
Sponge of dust would usually clog the air vent. It is extremely normal actually.
There you go, Dell Latitude E4300 disassembled.
