Keep USB power during sleep?

[bills742]

I have a Dell Inspiron 1720 laptop running Vista and a cordless logitech wave keyboard. I use an external monitor and I want to keep my usb ports powered during sleep so that I can use my keyboard to wake my computer from sleep without having to open and close the laptop lid everytime. Is there a way to do this? Thanks!

I think it's dependent on whether or not the motherboard keeps the USB slots powered in sleep mode. Some do, some don't. I know my HP does, and I can wake it from the keyboard, but my ASUS doesn't and I have open the lid to power it back up every time. As far as I know, I don't think there's any way to change this.

Hi

Not sure whether it helps,

Open Device manager.

Click Start, type devmgmt.msc

Please click on the + sign near to  Universal Serial Bus Controller, Many USB root hubs will be listed.

Double click on each USB root hub, Click the Power Management tab, Please un-check all the section "Allow this computer to turn Off this device to Save power".

Click OK.  Perform this steps for all USB root hubs and see.

Just a try, that is it

usually on a desktop there is a jumper that allows you to control the +5VSB voltage to the PS/2 Ports and the USB ports, however, as this is a laptop, the setting may be in the BIOS, or Sykes suggestion may work.

To access your BIOS, look for a message as the laptop is booting, like press F2 to enter setup, or similar. it may be Del (delete) F10, F9...different manufacturers have different keys, under anything relates to power /power management may lie your answer.

Something like USB power in sleep or something else similar.

Goodluck!

EDIT: I was right, you need to change a BIOS setting, I found it out on this page here http://en.community.dell.com/forums/t/19272402.aspx

So you just need to open the BIOS and change the Wake from USB setting under power management.

Check the settings in power options. You can create a custom setting that does not power off usb.

Does that carry over into sleep mode though? I was under the impression that only applied to while the computer was on, but idle for a certain amount of time.

You know, I'm not really certain since I don't use Sleep mode. You are correct that it works when powering down other components.
