Hi Adam, Are you able to sleep it manually using the sleep command in the Apple Menu or is that also not working?
In system preferences > Energy Saver - “Computer Sleep” slider. If a slider is set to ‘Never’, sleep is disabled for that feature. Check : Turn display off after is not set to Never Prevent computer from sleeping automatically when the display is off is not checked Wake for network access is not checked The three settings above can prevent or disrupt your Mac from going to or remaining in sleep. Additionally, you might want to click on the “Schedule…” button to make sure you haven’t accidentally set a schedule for when your Mac goes to sleep or wakes up. Worst case scenario, hit the “Restore Defaults” button to restore all settings to their default value. Another thing you could check. Do you have Internet Sharing turned on?
