How to open Dell Latitude 14 7440 – disassembly and upgrade options
Step 1: Opening the Dell Latitude 14 7440
- Prepare a clean, soft surface to place the laptop on to avoid scratching its surface.
- Locate and undo the 8 captive Phillips-head screws on the bottom of the laptop.
- Gently lift the bottom panel at one of the hinge areas to create a gap, then use a thin plastic tool to carefully pry the sides first, followed by the front, and finally the backside.
Tip: Proceed with caution around the ports to prevent any damage.
Step 2: Battery Replacement
- Disconnect the battery connector from the motherboard carefully to avoid any damage.
- Remove the 4 Phillips-head screws securing the battery, then lift it away from the chassis.
Note: The optional 57Wh battery provides extended usage times of up to 14 hours and 17 minutes for web browsing, or 11 hours and 7 minutes for video playback.
Memory Overview
The laptop’s memory is soldered onto the motherboard, offering a maximum capacity of 32GB LPDDR5-4800MHz in dual-channel mode. This 32GB variant is future-proof for most tasks, though it does not allow for memory upgrades.
Storage Upgrade
