How can I disable the beep when I plug in/unplug my laptop's AC adapter?

Question

My Packard-Bell laptop is emitting a loud, annoying beep when I connect or disconnect it to/from an AC power source.

Whether I have headphones plugged in or not does not change anything; the sound goes out of the speakers and wakes everyone up.

Do you know of any ways to eliminate this sound? I searched around the Internet and found a solution involving setting a specific volume bar to 0 in the playback settings, but I did not find it on my laptop. I am using Windows 7.

Answer 1

I think the option that will matter to you is the Power Control Beep. It's a BIOS setting, so you'll have to restart your computer to change it.

1. Either restart your computer, or shut it down and then power it back on.

2. When the boot process starts, open the BIOS settings menu. How you do this depends on your computer. Usually, it involves pressing F10, F1 or F12 on the first screen that comes up, before the "Starting Windows" animation appears.

3. In the BIOS settings, use the arrow keys — directions should be provided on-screen — to navigate to the Config menu, then the Alarm sub-menu.

4. Set Power Control Beep to "disabled." If you want to get rid of other beeping at the same time, you can set Low Battery Alarm and Password Beep to "disabled" as well.

5. Save and exit the BIOS settings application. Again, directions for this should be on screen. In my case, it was as easy as pressing F10 followed by Enter.

6. Depending on your computer, you may be asked which device you want to boot from. Select whatever you usually use (typically the HDD, or hard drive).

7. Tell your family members that they will no longer be woken up by your computer.

Answer 2

• open the "sound" settings in control panel
• in the "Playback" tab select the playback device (Conexant high def...) then click the properties box at the bottom
• go to the "Levels" tab and there you will see 2 volume bars
• Mute the "Pc speaker"

Answer 3

Acer Aspire 5740G solution to this problem: don't install (or uninstall) the Realtek audio driver. The notebook will run fine and have all audio functionalities with the built-in Windows driver.

(I have Windows 7 64 bit Ultimate. 100% working. I am very happy.)

Answer 4

For me it worked to do this:

Open registries by searching regedit in the start menu. Then go to HKEY_CURRENT_USER\Control Panel\Sound and on the Beep registry change the value to No.

Answer 5

For people not finding a solution with the above options, and that could not find the second speaker volume adjustment :

• Go to packardbell.com
• Go to support
• Go to downloads and go for your model number ( EasyNote is "EN TJ**" )
• Go to drivers
• Look for the Conexant audio driver and download it (be sure to check you are downloading for Win 32 or 64 bits)
• Install the driver
• Right-click the speaker icon to the bottom right corner of the screen
• Select playback devices (2nd option from top)
• Click on the speaker icon, then on properties
• Click on the level tab (2nd one from left)
• You should now see a second set of volume sliders (installed by update)
• Click on the mute button of the second one called PC Speaker
• Done

Good luck

Also, If you haven't found "power beeps" in BIOS, remove Realtek Audio driver and refresh device configuration from device manager. It'll install default audio driver. Sound works, no beeps
