In this video, we demonstrate how to replace the wireless card on an Inspiron 24 5430 All-In-One, or Inspiron 27 7730 All-In-One. Before you begin, turn off the computer and disconnect all the attached peripherals. Ensure that you always use ESD protection when working inside the computer. To begin, place your computer, display-down on a flat surface, with the stand over the end. Now, locate the tab underneath each stand. Then, push a scribe into the tab to release the stand from the display-assembly base. Similarly, remove the other stand.
Next, place your palm on the middle of the back cover, then, pry the back cover starting from the top to release it from the display-assembly base. Then, lift it away from the base. Remove the screws that secure the I/O cover to the display-assembly base. Pry open the corners of the I/O cover. Then, lift it away from the base. Next, remove the screws that secure the system-board shield to the display-assembly base. Then, lift it away from the base. Remove the screw that secures the wireless-card bracket to the wireless card. Then, slide the bracket off the wireless card.
Next, disconnect the antenna cables from the wireless card. Then, slide and remove the wireless card from the card slot. To install the wireless card, connect the white antenna cable to the main connector marked with a white triangle. Connect the black antenna cable to the auxiliary connector marked with a black triangle. Now, align the notch on the wireless card with the tab on the card slot. Then, slide the card at an angle into the card slot.
Next, place the wireless-card bracket on the wireless card. And replace the screw that secures the bracket to the card. Align the screw holes on the system-board shield with the screw holes on the display-assembly base. Then, replace the screws that secure the shield to the base. Align the screw holes on the I/O cover with the screw holes on the base. Then, snap the I/O cover back into place. Replace the screws that secure the I/O cover to the base.
Next, align the slots on the back cover with the slots on the computer. Then, press along the sides to snap the back cover into place. Now, insert the stand into its slot on the back of the system, until it snaps into place. Similarly, install the other stand.
