Only the Power Button Wakes PC from Sleep - Laptop

I check the bios, and there is nothing about using the keyboard to wake up the cpu from sleep.

• Open the Keyboard control panel item by typing keyboard into Start Menu.
• Click the Hardware tab, and then click Properties.
• Click the Change Settings button
  
  Note: This step requires Administrator access
• Click the Power Management tab, and then verify that the Allow this device to wake the computer is enabled.
• Click OK, and then click OK again.

I can follow everything, except I am stuck at ... because there is not such a tab I can see.
Click the Power Management tab

If your computer does not support Advanced Configuration and Power Interface (ACPI), the earlier steps may not be available. In this case, you have press the power button to wake the computer.
