Solve : Keep USB power during sleep?? |
|
Answer» 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!Quote from: bills742 on December 15, 2009, 05:36:09 PM I have a Dell Inspiron 1720 laptop running Vista and a cordless logitech wave keyboard.

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.Quote from: Allan on December 17, 2009, 05:51:44 AM 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.Quote from: Kurtiskain on December 17, 2009, 04:15:54 AM 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.

Refreshing to see a friendly ATTITUDE on CH Quote from: quaxo on December 17, 2009, 08:23:55 AM Does that carry over into sleep mode though?

You are CORRECT that it works when powering down other components. |
