It seems that as long as the monitor power LED is in the amber low power state I get the device notification sounds. When I turn it off there is no problem, but when I turn it back on i get one device disconnect and one device connect sound before the display comes on. remove the mother board battery for a time and insert it again. disable/enable the usb ports from the device manager. I have similar results if I turn off the monitor power. windows restore at the point when it was fine.

The driver I'm using is the vista driver because I have had no luck finding an actual W7 driver. I have an Acer V223w monitor connected via DVI to the onboard video of an Intel DG45ID motherboard.Ĭomputer Management Display Adapter Intel(R) G45/G43 Express Chipset (Microsoft Corporation - WDDM 1.1) Driver: Intel Corporation 8. This continues forever until I take some action that turns the monitor back on (press a key, move the mouse). When I have the power settings set to turn off the display, as soon as the display goes off the computer goes into a loop playing the device disconnect and device connect sounds.

Constant usb disconnect sound
