Display will not go to sleep (turn off) and screen saver will not activate

Interesting. I'm having a similiar, but unrelated problem with Win XP.

None the less, I googled around and turned up this thread. It's long, but it mentions a number of things you might try. In particular, updates to the MS Keyboard and mouse stuff might be something to consider.

I figured out what's causing the issue, but I don't know if there's a way to solve it.

I have two LED-Wiz controllers connected to my cab via USB. When those are plugged in the computer will not go to sleep or even activate the screen saver. With them unplugged, all is good. Sleep works great.

I've spoken to RandyT over at GroovyGameGear and he tells me that there is really no fix, as they are designed to not let the PC go to sleep (why, I have no clue - IMO that should be determined by the OS settings, not the hardware plugged into the computer).

If someone has a workaround, I'd be grateful!

I've got several LEDWiz controllers running under XP. I'm not sure about the screensaver, but I do have the screen set to powerdown after a while and that does work.

Honestly, I'm not sure I'd worry terribly much about not being able to automatically go to sleep. it's pretty trivial to setup a hidden button or some button combo that'll fire off a bat file to sleep the machine.

But, I tend to agree with you. Seems like hardware like the LEDWiz really shouldn't prevent going to sleep.

If the mobo has several different USB connections, you might try connecting them to different connectors.

Also, if you have a third party USB PCI card you can slap in there, try connecting your LEDWizs to it and see if it'll play nice then.

I'm not a hardware expert or anything, but usb devices can draw either a low amperage or slighly higer amperage current from your usb port. The ledwiz obviously needs the higher amperage. Here's the rub.... when windows goes into sleep mode, the current is turned down on all devices period. This makes sense normally as usb devices are typically input/output devices and you wouldn't be interacting with them when the computer is inactive. Randy desigend the ledwiz to be always on though, so I'm guessing he made it that way so the leds don't go dim/out whenever your cab goes into sleep mode.

It's probably in the coding, but a powered hub might help, I dunno.

I'm just astounded people still use screensavers in this day and age. There's this button marked "power" on your monitor somewhere.... I suggest you try it. ;)

When you have your monitor installed in a cabinet behind glass, it's a bit difficult to press the power button.
