[nfbcs] With silent disk, how do you know?

[Rasmussen, Lloyd]

Get an A M radio, put it on an empty frequency and place it near various parts of the computer. The sound of the whines, buzzes and burps can tell you a lot, especially when you have learned what "normal" sounds like. You probably won't experience dead silence even when the computer is off, because various power supplies will still be running and creating noise. This alternative technique also works in determining the state of cell phones, tablets, PC monitors, digital talking book players, etc.

With the new silent disks, how do you know your computer is doing something, when Jaws goes silent?  For instance, I have trouble making sure my new laptop is on.  I can feel a tiny draft from the fan, but it's very subtle.
Or, just now, my old work desktop decided to do an automatic update, and Jaws stopped talking.  The only way I knew the PC was still working was that I could hear the disk spinning, and, when it rebooted after the update, spinning for another few minutes before Jaws finally came up.
So, with the new silent discs, how do you know something is happening and you should just wait a bit?
Tracy
