Random bios style single beep while in windows. Help please!

Jump to solution

Hello, I own a Dell precision M6800 laptop that randomly makes one short bios style beep while in windows 8.1 during normal operation not when booting.

The system sounds are turned off so the beep is not from windows. Also the beep occurs through the speakers when I have my headphones plugged in so I think it's actually the motherboard speaker making the beeps.

I have checked the windows event log but no errors or warnings are logged at the times when the beep occurs. The laptop works fine no glitching or error notifications during the beep, but it gets annoying after a while and I'm worried that it could indicate some actual problem with the hardware.

The beep occurs sometimes seconds apart, other times minutes to hours apart and some days, not very often, it can go from boot to shut down (more than 12 hours) without any beeping.

Any ideas on what could be causing this?

Hello, 

Have you tried updating BIOS?

Does the  system saves Date and time accurately ?

Can you try running diagnostics from f12 menu.

Awaiting your reply.

Hello Hemalatha, I have upgraded to all the new BIOS versions, the problem was present in every version, I am now on version A11. I have not tested the latest version A13 thoroughly (A 12 was skipped)  because on this version the laptop refuses to shut down completely when using the shut down option in windows, only when using the hibernate option the laptop stops completely, so definitely something odd there too. I will try A 13 again to see if the beep is ocuring.

The system keeps time and date accurately as far as I can tell, windows did not popped any notifications notifying that the time or date are going out of sink, but it is set to automatically synchronize with a time server. I won't use this option in the future to see if the time goes out of sync.

Running the diagnostics doesn't find any problems, not even in the extended mode.

Okay. Do let me know if the beep is heard on A13 bios.

If it still persist its the motherboard which is at fault. 

Will wait for your reply as per that we will proceed further.

Hello, thank you for taking interest in this issue.So far so good, the A13 BIOS works ok and shuts down the laptop normally which is a relief.

As for the beep it occurred today and something curious happened just a split second before, a black command window appeared that had the title taskeng.exe and disappeared quickly and then I heard the beep. This is the first time I have seen the command window, doing who knows what, correlated with the strange motherboard beeping.

I immediately searched on what taskeng does and I found out that it has to do with scheduled tasks, but I didn't schedule any tasks so I have downloaded some antispyware and antimalware software to check for any malicious software, some threats were detected on the system and deleted. My antivirus did not detect anything wrong which is why I did not took into consideration that this could be a malicious software problem.

Now I'm waiting to see if this has resolved the issue.

The short beep is still present and as random as ever. Got one yesterday at about  1 pm and one today at 9:05 pm. There is still no error or warning in the event log at the specified times.

I really do hope it's not the motherboard at fault because it was replaced once already. I have run the preboot ePSA diagnostics tests again, but everything still checks out ok. Any other diagnostics I can run besides ePSA?

Could this actually be due to the Windows 8.1 installation having some bugs or because it was not installed correctly for some reason? I have installed all the recommended updates for windows as well, but the beep problem never went away.

Hello, 

As I mentioned in the PM about HDD/motherboard.

Post messaging you i have been checking with few of my personal blogs, its to do with HDD alone.
