How to Put a ThinkPad to Sleep

You can greatly extend the battery life of your Lenovo ThinkPad by putting the computer to sleep when you are not actively using it. In the Sleep state, Windows 7 uses minimum battery power to keep the contents of the computer's memory active. The processor, screen and hard drive are turned off. An additional benefit is that your ThinkPad can resume from Sleep very quickly when you want to begin using it again. Sleep allows you to avoid waiting for the computer to perform a complete startup process when you turn it back on.
