This ubuntu machine is for testing purposes only :-p Anyways, it's bad that we have to manually unload several modules, specially usb. I'm sure windows reaches 9 watts consumption without breaking functionality. And that's the big thing. I think that's something we should be aiming. Dontcha think? > See http://thunk.org/tytso/blog/2007/10/29/tip-o-the-hat-wag-o-the-finger-linux-power-savings-for-laptop-users/ Good article, but still. On the end user point of view, it's difficult to do rmmod/insmod operations. Recently I sent a patch to the bluez team adding a checkbox to bluetooth-properties that would send the SetMode("off") dbus message (which is the same as running hciconfig hci0 down). That helps a bit, but still the driver is not been used and keeps generating wakeup events. Why if it's not been used ? Maybe this is something we should start thinking about, right ? -- Best Regards, Felipe Balbi felipebalbi@xxxxxxxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
