Rapid Beeping at Startup

I am using Windows 7 Pro on a Dell Inspiron 1520. Today, when I attempted to start the unit, I heard a rapid beeping that was uncontrollable until I clicked the Control Key. There are no error messages.
I have done 2 cold boots and a memory diagnostic (which found no errors) with no positive results. It begins right when the screen indicates it is Starting Windows. Once I get past that, it seems to operate normally, but I am concerned there is a root problem that will surface with disastrous results at a later time.
Any suggestions, thoughts or ideas are greatly appreciated.


Hello Jake,

As you did not indicate the amount of beeps (1, 3, 5 etc:) or whether they are long beeps or short, or both, maybe someone is sending you morse code, sorry, couldn't resist.

Anyway have a look here, see if it helps;
Dell BIOS Post Codes - BIOS Central


It' hard to say....I can hear breaks in the tone, but for all intents and purposes, it is a long, steady stream which is unintelligible in order to determine what error code it is sending. It almost sounds like one, long beep as if a key were stuck (but this is not the case). The ONLY way to stop it is by hitting the Control key. But as far as determining any pattern - not possible.

As far as I know, beeps only indicate a hardware issue, not software.

When was the last time you cleaned the inside of the laptop?

Just guessing, that if the Ctrl key shuts it off, it may be the keyboard.

Hope this helps

I have taken the keyboard off before, but unfortunately it is made in such a way that there literally is no way (or reason) to clean it other than with air and cleaning the buttons from fingerprints. However, I took a shot and tried Safe Mode, and the Control button did nothing to eliminate the sound. I just restarted in normal mode and again the Control button worked. I'm not sure that sheds any light, but I thought it was worth mentioning.

Lets try this, go in to the BIOS and check for any enabled alarms, especially battery alarm and disable them.

Just another thought, is it a Samsung hard drive?
If so, go here New URL and download the drive utility for your model and disable the "Acoustic Management"

At this point, I would advise you to start backing up any important files you may have in case of HDD failure.
