1. Allow The Computer To Turn Off This Device To Save Power Windows 7

Hi LDZ2012,thanks for posting here.I want to disable or enable “allow the computer to turn off this device to save power” for USB/USBHUB devices.What's the method in VC/MFC or powershellFor this case, I suggest you use which represents the management characteristics of a USB device. You could use themethod of the CIMUSBDevice class which sets the desired power state for a logical device and when a device should be put into that state.Hope this could be help of you.Best Regards,Sera YuMSDN Community Support Please remember to click 'Mark as Answer' the responses that resolved your issue, and to click 'Unmark as Answer' if not.

I want to disable the option to 'Allow the computer to turn off this device to save power' for all computers in a select group of OUs. I want to do this via Group Policy rather than a script if I can help it. Go to the 'Power Management' tab in the properties dialogue and uncheck the box for 'Allow the computer to turn off this device to save power.' If you're using a laptop, you may also need to go into your advanced power plan settings and disable the option that allows Windows to cut power to devices when they are not in use.

Here's an interesting one I haven't seen on ServerFault I'd like to 'discuss' based on our rule regarding a question.I have a ton of Windows 2008/2012 VMs in my environment running under VMWare 5.1 and 5.5 clusters.There is a setting that is pretty common on NICs that allows to you check/uncheck stating Allow the computer to turn off this device to save power. The default is for this to be checked. The concept being to help save power if the NIC isn't plugged in and shown as enabled and active in Windows (is my understanding). EDIT: the before is actually an incorrect passed down falsehood.This KB article does a better job of explaining what this setting does: It doesn't simply turn off the device if there is some idle time.Now we get into the VM world side of things.Does such a setting have any bearing checked or unchecked on a VM? Unchecking it seems frivolous since the NIC isn't a physical device and isn't drawing any actual electrical power regardless.

But does leaving the box checked having any negative affects when Windows likes to believe it is a physical device? Should all VMs have this box checked or unchecked?
