Windows 7: Keyboard Non-wake anomaly

Keyboard Non-wake anomaly

Without going into the lengthy details, suffice it to say that this morning, after doing a test for SuperAntiSpyware, I found that I could not wake the computer using the keyboard. I normally use the mouse, but as I had removed the wireless mouse dongle in testing, I could not use it, so tried the keyboard, to no avail.

A quick press on the computer's power switch woke it up, and replacing the dongle re-energized the mouse. I then went into Device Manager, which lists two HID Keyboard Devices, although I have only one keyboard. One on-line article says that this is not unusual for Windows to list more than one. In Device Manager, I determined that both entries show that they are set to allow them to wake the machine. powercfg -devicequery wake_armed also indicates that both are properly set.

Why, other than that my computer is just trying to be unfair, can I not wake the computer with a keyboard that supposedly is set to allow it to do that?

(I forgot to mention that the keyboard is USB, not wireless.)

Check in your BIOS and see if there is a wake setting involving the keyboard. Some BIOSes have a "Wake on Keyboard" parameter, or you can select a key to wake the PC up, such as the space bar.

Not only will my keyboard not wake the computer, now it won't save a message that, at least in theory, I posted in this thread yesterday. It was likely operator error, and my excuse is that i was quite tired, having been working all day on a yearly task, washing and waxing the floors of our house; the floors are scored concrete, to absorb the heat of the sun in a passive-solar domicile.

Anyway, what i thought I had posted was that I think it unlikely that I had never used the keyboard to wake the computer, which is over three years old, but despite that reservation, I shall check the bios and post my findings (or perhaps just try to post them...) when I have a chance to do the checking.

I checked the bios, where USB keyboard and mouse enabling are in a single setting, which is set to `enabled.' Given that a USB mouse wakes the computer, and that the keyboard is, within Windows, enabled to wake the computer, something else must be blocking the keyboard from waking the machine.

Very odd. I checked mine to see as I always wake via the mouse, and my computer wakes by the space bar only. No other keys wake it up.

Strange behaviour.

I agree, and wish I knew what the Medieval Chant is to fix this (academically, I am a medievalist.) I have tried every key on my keyboard, and none of them wake the computer, alas. I wish I knew if I had ever used the keyboard to wake the machine; if I knew that it had worked, at least I would know that something had happened since then--but ever if I knew, I have no idea how I could track down and fix the culprit.
