In Windows 7, when my laptop comes back from standby, my external mouse and keyboard cannot be used to "login" or "unlock" my station. Once I'm logged in again, they are recognized and work properly.

Is this a security feature that I can turn off?

Update: My laptop is a Dell XPS-1330M, and the keyboard is made by Dell. The mouse is a simple Microsoft mouse.

  • I believe it has something to do with devices not being installed until a user is logged in, but it is indeed strange that they seize to work when returning from standby. I'm curious to see the solution. Jan 24, 2010 at 21:25
  • I had a laptop that when the laptop went into power save it killed the USB devices. However, when I woke up the computer it took a while for it to power up the USB devices. I don't know if the problem was in the power management, it's BIOS was pretty well locked down. Also, I'm wondering about the setting to have USB device wake the computer from sleep. Good luck.

  • Can you post make and model of your laptop and the wireless devices? A more general answer: In some low-power states, the wireless transceiver may be unable to receive information from the wireless devices.

  • Adding into Molly's answer. Check your power settings. I know mine originally turned off usb stuff. Jan 24, 2010 at 22:50
  • If it's a power setting, then it's a power setting that focuses on signing in. It's weird, but it's not time related. I can wait a long as I want, it won't enable the devices. Jan 25, 2010 at 12:38
