energy saving with wireless mouse and keyboard

Hi there migmartinez,

It sounds like you are looking to conserve battery life of your bluetooth mouse and keyboard by turning off your computer. You can switch off your mouse with the button on the bottom. When you turn it back on it will automatically re-pair with your computer:

Your keyboard does not however, have an off button. You could remove the batteries but I can see how that might be impractical:

Thank you for using Apple Support Communities.

Oh interesting, so your computer isn't going to sleep when it should be. I would suggest the steps in the following article to help nail down what might be preventing it from sleeping:

If your Mac doesn‘t sleep or wake when expected

If your Mac doesn't go to sleep when you expect

Check your Energy Saver settings as described above, and be aware that your Mac won't automatically go to sleep unless it's inactive:

• The same network activities that can wake your Mac can also keep your Mac from sleeping.
• Any app or other process that's running on your Mac could also be keeping your Mac awake. Check the Energy Saver pane of Activity Monitor to identify apps that need your Mac to be awake. If "Yes" appears in the Preventing Sleep column for an app, your Mac won't automatically sleep while the app is running. Other apps prevent sleep only when doing certain things, such playing music or video, or printing, or downloading files.

If you started from OS X Recovery on a Mac notebook, automatic sleep is disabled as long as the Mac is using AC power.

These additional steps may help identify or resolve the issue:

• Reset the SMC.
• Reset NVRAM.
• Disconnect external devices other than your Apple keyboard, mouse, and display. If that resolves the issue, gradually reconnect your devices, testing each time, until you find the device that is interfering with sleep. Then check the documentation that came with the device, or contact the device manufacturer.
• Start up in Safe Mode to see if the issue is related to non-Apple startup items, login items, or kernel extensions.
• Try to isolate the issue by using another user account.
