What is the quickest way to wake my computer up from sleep?
Clicking the mouse button is the fastest way to wake the computer. To wake the computer up using the keyboard, press any key. In some circumstances, you may need to press the space bar on the keyboard to wake the computer. If this doesn’t work, open the Bluetooth System Preferences (choose System Preferences from the Apple ( ) menu, then Bluetooth from the View menu. Select the Advanced tab in the Bluetooth System Preferences pane) and make sure to enable the checkbox next to “Allow Bluetooth Devices to wake this computer”. If this selection is grayed out, it is enabled by default.
