How to solve this problem? Thank you!

A: Some motherboards need to enable sleep support in the BIOS, you can check in the "Device Manager" system to see if there is a call called "ldquo; The option of ACPI-Compliant System” otherwise it is not a prerequisite for sleep and needs to be turned on in the BIOS.

In addition, you must ensure that all current hardware compatible Windows 7 drivers, such as wireless network card drivers, Bluetooth drivers, etc., are properly installed. If you are not using the system, turn off the unconnected Bluetooth, unconnected wireless. Unmatched and turned on hardware such as the network.

Expand “Computer”→“Manage”→“Device Manager”, then right click on the NIC and other devices, <;properties", will <;allow this device Wake up the computer & rdquo; remove the hook in front, and then view the status of power management through the PowerCFG command line (“start”→“program”→“accessory”→“command prompt”→ Type “powercfg -a”).
