Let me know how to activate/turn on Blue tooth on dell e6410 lap top.
Welcome to the Community. First check if Bluetooth is enabled in the BIOS, by pressing the F2 key at the Dell Logo to enter the Bios. Move to Wireless, and under Wireless Switch make sure Bluetooth Switch and Wi-Fi Switch is checked, and then click on Apply. Then move down to Wireless Devices and check Enable Internal Wi-Fi, and Enable Internal Bluetooth, click on Apply, and then save changes and exit. Use the below link for help.
Use the wireless switch on the side of your laptop to turn on Bluetooth and Wireless.
Hope this helps.
