When you use a Microsoft mouse or keyboard that is listed in the 'Applies to' section, you may experience one of the following symptoms:
You may be unable to wake the computer from sleep or standby mode by using your mouse or keyboard.
After you wake your computer from standby, your pointing device may not work.
When you press the SLEEP key on a keyboard that has a Sleep key or has a key that is configured to activate Sleep, the computer does not go into Sleep mode.
This issue may occur if one or more of the following conditions are true:
You are running Windows Vista and have not updated to Service Pack 1 or a later version.
The Basic Input/output System (BIOS) system that is installed on the computer reduces power to the port to which the input device is connected.
Note You may be unable to use Bluetooth devices to resume operation from certain power management states (such as 'suspend' or 'hibernate'). In some low-power states, the wireless transceiver may be unable to receive information from the Bluetooth devices.
You are using a portable or notebook computer that does not allow resume by using a Bluetooth device. If you are having problems waking a laptop by using a Bluetooth device, see Method 3 first.
The Keyboard item in Control Panel is not configured to wake the computer when you press a key on the keyboard.
Your computer may have encountered a system problem.
The Sleep key on your keyboard is configured incorrectly.
If pressing the Sleep key again does not resolve this, try each of the following methods in the order in which they are presented and determine whether the problem still exists before you try the next method.

For information about how your system resumes operation, see the documentation that accompanied your computer or contact the computer manufacturer. For information about Microsoft Windows Power Management settings, see Microsoft Windows Help.
Note Many laptop manufactures will not allow a Bluetooth device to wake the computer from sleep mode because of the power consumption requirements to keep the Bluetooth radio activated (Bluetooth paging can consume up to 15% of the computer’s power). Therefore there are a couple of workarounds that you can use:
If you can open the lid of your laptop, use the embedded keyboard or pointing device or an external non-Bluetooth device to wake the computer.
If you cannot open the lid (for example, because it is in a docking station) or if you have it plugged into external power (that is, you are not using the battery), you can change the Power settings in Windows to not go into Sleep mode when plugged in.
Alternatively the Microsoft Bluetooth stack or your laptop’s proprietary Bluetooth stack may allow customization to allow wake by using Bluetooth devices.
Method 4: Examine the BIOS settings of your computer for power features that disable or reduce power to ports that are used for your keyboard or mouse
Because BIOS access varies by computer, to resolve this issue, see the documentation that is included with your computer. Alternatively, contact your computer manufacturer for information about how to configure the BIOS.
For more information about hardware and software vendor contact information, visit the following Microsoft Web site:
The ability to recover from sleep mode by pressing a key on the keyboard or by moving the mouse on a computer that supports ACPI is dependent on the computer's motherboard. This ability is disabled in older Intel motherboards, and the only way to wake the computer from sleep mode is to press the Power button.
With most newer motherboards, you can wake the computer by pressing the Power button, by pressing a key on the keyboard, or by moving the mouse.
ACPI support is necessary to take full advantage of the power management and Plug and Play features in Windows. If you are not sure whether your computer is ACPI-compliant, please see the printed documentation for your computer or motherboard, or contact the manufacturer of your computer or motherboard.

There are a number of different ways to lock or sleep your screen in macOS. Before we show them to you, however, it’s important to make the distinction between locking your screen and just putting it to sleep.
If you lock your Mac you’ll put it to sleep and need to type in your login password on your Mac’s lock screen (or unlock it with TouchID on a MacBook Pro with Touch Bar, or with an Apple Watch). If you put it to sleep, you won’t necessarily lock it. In order to lock your screen, you need to set up the password in System Preferences. Here’s how to do that.
How to set up a password to lock the screen
- Launch System Preferences either by clicking on its icon in the Dock or by choosing it from the Apple menu.
- Click on the Security & Privacy pane.
- Choose the General tab and check the option that starts ‘Require password…’
- Choose an option from the dropdown menu.
Now, whenever your Mac goes to sleep or a screensaver starts, it will lock and you’ll have to authenticate with your user password, Apple Watch or TouchID to gain access.

How to lock your Mac
If you have a MacBook, a MacBook Air or a MacBook Pro, the quickest and easiest way to lock your Mac is just to shut the lid. When you do that, the Mac goes to sleep and when you open it again you’ll need to unlock it.
However, there are occasions when you’ll want to prevent anyone from seeing the screen without actually closing it. And, in any case, if you have an iMac, Mac mini or Mac Pro, it’s not an option. Here are some other ways you can lock your Mac’s display.
1. Use Apple menu
Go to the Apple menu and choose Sleep. This will display the login screen for your account and won’t unlock with a password (unless you’re wearing an Apple Watch when you do it and then it will lock and unlock immediately)
Tip: If you want your Mac to remain locked even when you’re close by and you have an Apple Watch, go to System Preferences>Security & Privacy>General and uncheck the Allow your Apple Watch to unlock your Mac option.
2. Use shortcuts
If you’re using a Mac that’s running macOS Catalina, go to the Apple menu and choose Lock Screen or press Command+Control+Q. This will lock your Mac and return you to the Login screen.
For older versions of the operating system, press Control+Shift+Power button (or Control+Shift+Eject if your Mac has an optical drive). It will lock the screen.
You can also use a keyboard shortcut to put your Mac to sleep. Press Command+Option+Power (or Eject). This works in a similar way to the previous one, but rather than just lock your Mac it powers down the hard drive, puts the CPU into low power mode and stops background tasks in order to save energy.
3. Set up a hot corner

Hot corners allow you to drag to the mouse pointer to one of the four corners of the screen to initiate an action – you can use one as a sleep shortcut on your Mac. To set it up:
- Launch System Preferences.
- Choose the Desktop & Screen Saver pane.
- Click the Hot Corners button at the bottom right of the window.
- In the drop down window, choose a corner.
- Click on the menu and choose either Start Screen Saver or Put Display to Sleep.
4. Use fast user switching
Fast user switching allows you to quickly log into another user account on your Mac. But you can also use it to return to the log in window, which locks your Mac. Got to System Preferences>Users & Groups and click the padlock, then type in your password. Click Login Options and check the box next to ‘Show fast user switch menu as.’ You can also choose whether to show the menu as your full name, the account name or an icon.

To lock your Mac, click the fast user switching menu at the right of the menu bar and choose Login Window…
5. Add Keychain Access to the menu bar
This option was removed in macOS Mojave but works on versions before High Sierra:
- Go to Finder.
- Choose Applications > Utilities.
- Launch Keychain Access.
- Click in the Keychain Access menu and select Preferences.
- Check the box next to Show keychain status in menu bar.
- You’ll see a lock in the Finder menu bar. Click it and choose Lock Screen to lock your Mac.
Other ways to protect your privacy
First of all, fet a Finder-like Terminal for Mac that will help you completely control the login settings. It’s called MacPilot. The app covers over 1,200 hidden macOS features. For privacy, you can go into the Login tab and customize access by users, enable the option of automatic screen locking, and edit launch items.
If you’re looking for physical protection of your Mac, Beepify is the app you need. Whenever you have to step away from the computer in a public place, activate Beepify and it will be set to produce a loud sound in case someone tries to close the screen or disconnect charger.
One of the main reasons for locking your Mac when you step away from it is to stop prying eyes accessing your files, browser history, or anything else you don’t want them to see. CleanMyMac X has a tool that gives you even more privacy protection.
CleanMyMac’s Privacy tool allows you to quickly delete your browser history in Chrome, Firefox, and Safari. But it also allows you to delete message threads and attachments in Messages, and to remove entries from macOS’ recent files lists.
Also, CleanMyMac’s Shredder is a quick and easy way to securely delete sensitive data. You can download CleanMyMac for free and give it a try.
As you can see, putting your Mac to sleep or locking it is very easy. There are lots of different ways to do it, although some are dependent on the version of macOS you’re using. If you regularly lock your Mac to prevent others accessing it, you should ensure your login password is strong and secure.
Finally, if privacy is important, CleanMyMac has a couple of tools that can help delete sensitive data.
