First run the onboard hardware diagnostics(tap F12 on start up,select Diagnostics) to check if its a hardware issue Post back error code/message if any.
Hello, My laptop does 2 short beeps, a pause, and a quick beep, and goes on to beep continuously about 56-60 times. I looked at beep codes and all but could not find the particular kind of beeping pattern I am facing with my laptop right now (Inspirion 5500). I know the battery is reaching the end of its usable life but  I am not sure if that's what causing such beeps. Thank you!
Weird beeping sound
