I am new to Windows 7 I dono where is the settings to alter sleep time in Windows 7.
1. Goto Control Panel in Windows 7.
2. Click “System and Security” , look for “Change when the computer sleeps” within the “Power Options” section,
3. Click on that and you’ll find that it’s really easy to tweak things as you desire,
4. Make the changes you want then click on “Save changes”.
