Hi walkerr21,
Check if Internal Bluetooth is enabled in BIOS. Restart the computer and tap F2 at Dell logo.
Under “Advanced” check if “Internal Bluetooth” is enabled.
If the issue persists, reseat the bluwtooth card on the computer.
Refer the following link which has steps to reseat the Bluetooth card:
From the above link click Service manual to access Memory reseat/remove section.
Before Opening the chassis, I recommend you to remove the battery and disconnect the adapter, press and hold the power button for few seconds and release to drain the flea power.
****NOTE: Please ensure that the power cable of the computer is disconnected before opening the chassis. Refer to the Service Manual for assistance on removing or replacing the internal components of the computer.
Awaiting your response!
