This video shows how to replace the M.2 2280 solid-state drive on an Inspiron 14 Plus 7440. Before you begin, create a recovery drive and back up all data. Ensure that you always use ESD protection when working inside the computer. First disconnect all the attached peripherals and enter Service Mode. To do this press and hold the B key on the keyboard, and then press the power button. Now, the computer will boot up and the Owner Tag information is displayed on the screen. Press any key to proceed, the computer will emit three short beeps and shut down.
To remove the bottom cover, loosen the two captive screws and then remove the five screws that secure the base cover to the palm-rest and keyboard assembly. Using a plastic scribe, pry the base cover from the top left at the hinge, and then continue to work on the sides to open the base cover. Slide and lift the base cover off the palm-rest and keyboard assembly. To remove the M.2 2280 SSD Remove the screw that secures the M.2 2280 thermal shield and SSD in place. Slide and lift the shield off the drive. Then lift the drive at an angle and remove it from the SSD slot. Now, let’s install the M.2 2280 solid-state drive. Locate the notch on the SSD.
Align the notch with the tab on the SSD slot. Slide the drive into the SSD slot on the system board. Place the thermal shield on the drive. Replace the screw that secures the SSD and the thermal shield to the system board. Now, let’s install the base cover. Align and snap the base cover into place on the palm-rest and keyboard assembly.
Tighten the two captive screws on the base cover and then replace the five screws that secure the base cover to the palm-rest and keyboard assembly. With the computer assembled, connect the power adapter. Press the power button to power on the computer to exit from Service Mode. Please note the computer will only turn on if the power adapter is connected. If you need more information or assistance, go to Dell.com/Support.
