Hi there My system waked randomly and I can't figure what is causing it. Control panel is set with disabled wake timers, and the lan and usb devices is set disabled wake up as well. Although the system is still wakes up randomly. When its happening I'm checking in the cmd powercfg –lastwake and its always return ACPI\PNP0C0C\2&daba3ff&1 And never detail about the actual device. Im with intel mv850 motherboard and there isnt updated drivers. All the drivers are installed correctly by microsoft 1. Is there another useful way to know what wakes up the system? 2. What can I do?
