Hi Nilesh,

I recommend running diagnostics on the computer. Below link would help you run diagnostics on the computer:

Kindly private message the service tag of the computer so that I can check the wireless card installed and assist you.

I have added you as a friend. Please accept my friend request by clicking on my name highlighted in blue and then click on “Friends” tab at the top and then click on “Request to Review” and finally click on “Accept” button.

I am sending you a private message as well. Click on “Inbox” to respond to the message and provide system’s Service Tag and contact details so I may access your system records and check for further course of action. You could also click on Start Conversation to send a private message.

Awaiting your response!

I am having the exact same problem with my Inspiron 17R N7110 laptop. I have already run the diagnostics and it didn't find anything. Any help would be appreciated.

I was looking for a solution to the same problem, and found it!

apparently it's an accessibility setting:

- Go to "ease of access" on windows 7
- Go to "Make the keyboard easier to use"
- Turn off "Toggle Keys"
- Press "OK"

Now the beep is gone.
