I have a Thinkpad T430s. I found on other Thinkpads there's a beep when you plug or unplug the AC cord. While I hear a lot of people say it's annoying it seems like a very useful security feature. However, when I go into the Power Manager the option to beep on plugging/unplugging ("Power State Change Beep") isn't there, even though it's in the help file already.

I know it would be easy to rig a software solution to this event, but it would kind of defeat the purpose if it doesn't beep when it's in sleep. Is there a way to get this beep on my laptop?

Have you checked for options in the BIOS? – terdon Dec 2 '12 at 16:59
Not in there :( – digitxp Dec 2 '12 at 16:59

I enabled this on my ThinkPad Edge. The setting is in the BIOS, so you would have to look in there for it.
