Hi, my laptop doesn't utilize any of my power settings (dimming, turn off screen, sleep mode, screensaver etc). I noticed that everything works fine if my USB speakers aren't plugged in. I have a pair Altec Lansing XT1. Windows come with drivers dated from 2009 and says everything is working fine. I also noticed that the power, and volume buttons on the speakers don't work either. I need my USB speakers, so how do I get windows to still make use of the power settings? Thank You
