This tutorial provides step-by-step instructions for removing and installing the speakers on your Dell Pro 16 PC16250 or PC16255.
Before you begin, turn off your computer and disconnect all attached peripherals.
Always wear an ESD wrist strap while working inside the computer to prevent damage due to electrostatic discharge.
In this video, we will demonstrate how to replace the speakers on your Dell Pro 16 PC16250 or PC16255. Ensure that you always use ESD protection when working inside the computer. Turn off your computer and disconnect all the attached peripherals.
To enter Service Mode, press and hold the B key on the keyboard, then press the power button. The system will boot and display the Owner Tag screen. Press any key to proceed, the computer will beep three times and shut down.
To begin, loosen the nine captive screws that secure the base cover to the chassis. Next, use a plastic scribe to pry open the base cover. Start from the U-shaped indents near the hinges. Continue prying along the top and sides to release the base cover and remove it.
Now, let’s locate the speakers on the palm-rest assembly. Disconnect the speaker cable from the connector on the system board. Using a plastic scribe, remove the speaker cable from the routing guides. Carefully lift and remove the speakers from the palm-rest assembly.
Now, let’s install the speakers. Using the alignment posts, place the speakers into their slots on the palm-rest assembly. Ensure the rubber grommets are properly seated and securely attached to the speakers. Now, using a plastic scribe, route the speaker cables through the routing guides on the palm-rest assembly.
Connect the speaker cable to the connector on the system board. Align the base cover with the palm-rest assembly and snap it into place. Tighten the nine captive screws to secure the base cover to the palm-rest assembly. Once the computer is fully assembled, connect the power adapter.
Press the power button to turn on the computer. Please note, the computer will only turn on if the power adapter is connected. For more information about Dell Pro 16 PC16250 or PC16255, visit: Dell.com/Support.
