What if Windows 7 can't "sleep" properly?

        Q: My notebook is ASUS K50AB. After upgrading from XP to Windows 7, the notebook can't use the "sleep" function normally. After using the sleep function, it can wake up, but the screen is black, you can't see it, reinstall the system. This is still the case. How to solve this problem? Thank you!

A: Some motherboards need to enable sleep support in the BIOS. You can check if there is an option called "ACPI-Compliant System" in the "System Device" of "Device Manager". Otherwise, there is no prerequisite for sleep, and it needs to be enabled in 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" → "Management" → "Device Manager", then right click on "Properties" on the network card and other devices, remove the hook in front of "Allow this device to wake the computer", and then pass PowerCFG The command line checks the status of power management (Start → Programs → Accessories → Command Prompt → type “powercfg -a”).
