Locking your laptop without putting it to sleep can be done in several ways, depending on your laptop model and operating system. For example, on a Windows 10 laptop, you can use the Win+L key combination to lock your device without activating sleep mode. Additionally, you can adjust power settings to keep your laptop running when you close the lid, although this may cause overheating. On a Mac, you can set up a Hot Corner to quickly activate the screen saver and lock your screen without waiting for the screen saver to start.

What You'll Learn
Turn off 'Close lid to sleep'
To stop your laptop from going to sleep when you close the lid, you will need to change your power settings.
For Windows 10, you can do this by right-clicking on the battery icon in the bottom right corner of your screen. From the menu, select 'Power Options' and then 'Choose what closing the lid does'. You will then be able to choose 'Do nothing' under the 'When I close the lid' option.
Alternatively, you can use the Windows search function to find 'lid settings' in the start menu. This will take you to the same 'Power Options' menu as above, where you can change the settings for what happens when you close the lid.
If you are using a Lenovo Thinkpad, you may need to change the Attributes DWORD value to 2. This will make advanced settings visible, where you can then set the sleep timer to zero minutes.
If you have a Dell laptop, you may need to disable 'connected standby'. You can do this by opening Command Prompt and typing 'powercfg /a'. If the output shows that your laptop is in an S0 profile, then it is in 'connected standby' mode. You can then disable this by changing the power settings to 'hibernate after' or 'sleep after'.
It is worth noting that some laptops may have different power settings, so it is always a good idea to check the documentation that came with your laptop or go to the manufacturer's website for specific instructions.

Use third-party tools
If you want to lock your laptop without putting it to sleep, you can use third-party tools. These tools can simulate user activity or override sleep settings, ensuring your system remains active without needing manual adjustments. It is recommended to always download third-party tools from trusted sources and keep the software up-to-date to avoid vulnerabilities and compatibility issues.
One such tool is Laplock, a lightweight (50KB), open-source tool developed by Etienne Dechamps. To use Laplock, download the latest laplock.exe release and open the Windows Startup folder by using the 'shell:common startup' run command. Then, simply add laplock.exe to your Startup folder. Alternatively, you can use Lid Lock to achieve the same result. Note that closing the lid on your laptop may restrict airflow, which could lead to overheating and potential physical damage, including battery failure or explosion.
Another option is to use tools like Wakeful, Caffeine, and Insomnia, which are popular applications that prevent your device from going to sleep. These tools can simulate brief mouse movements to keep the system from going idle, and you can set intervals for simulated activity to suit your preferences. If you want Wakeful to run automatically, look for an option like "Run on startup" or "Launch at boot" in the app's settings.
Additionally, you can use powercfg /a in cmd to check if your computer is in 'connected standby' mode. If it is, you can disable this mode to switch back to traditional standby mode, which may help prevent your laptop from going to sleep after locking.
Finally, you can try adjusting your screen timeout settings to set how long it takes for your screen to lock or go to sleep. This will allow you to lock your screen without waiting for the screen saver to start.

Disable 'Connected Standby'
To disable Connected Standby, you can try running powercfg /a in cmd. If the result shows that your computer is in an s0 profile, this means that 'Connected Standby' is enabled. Disabling this will allow you to switch back to traditional standby mode.
Connected Standby is a feature that keeps part of your device active and awake, even when it is locked, so that it can perform functions such as downloading emails and notifying you of their arrival. This is different from Hybrid Standby, which keeps the device's RAM powered so it can instantly resume where it left off, but also copies it to disk and, after some time, turns off completely to conserve power.
To disable Connected Standby on a Dell XPS 15 9570, you can try checking the BIOS, as some users have reported finding the option to disable it there. However, it appears that Dell removed this setting in BIOS version 1.3.
It is worth noting that some users have expressed discomfort with the idea of deleting the ModernSleep keys in the registry to disable Connected Standby, as this has not been confirmed to work on all devices. Additionally, some laptops may overheat if they are not sleeping properly, so it is important to ensure that the correct power settings are configured for your specific device.

Set Attributes DWORD value to 2
To lock your laptop without putting it to sleep, you can try changing the Attributes DWORD value to 2. This will allow you to access the advanced settings and configure the time before your laptop goes to sleep.
Here's a step-by-step guide on how to do this:
Step 1: Understanding DWORD Values
First, it's important to understand what DWORD values are. DWORD stands for "double word" and represents 32 bits of data. In the Windows registry, DWORD values can be stored in decimal or hexadecimal format, and their interpretation depends on the application or Windows component using them.
Step 2: Accessing the Registry
To change the Attributes DWORD value, you need to access the Windows Registry. This can be done by opening the "Run" dialog box (Windows key + R), typing "regedit", and navigating to the following path:
> HKLM\SYSTEM\CurrentControlSet\Control\Power\PowerSettings
Here, you will find various power-related settings, including the Attributes DWORD value.
Step 3: Changing the Attributes DWORD Value
Right-click on "Attributes" and select "Modify". Set the value data to "2" and click "OK". This will enable the advanced power settings.
Step 4: Configuring Advanced Settings
Now that the advanced settings are enabled, you can configure how long your laptop stays on before going to sleep when locked. Go to your power settings and find the "Advanced power settings". Here, look for the "Sleep" or "Sleep after" settings. Set the time to your preference, or set it to Never if you don't want your laptop to sleep automatically.
Step 5: Testing the Changes
After making these changes, lock your laptop using the Win+L key combination and observe its behaviour. It should now remain on without going to sleep, according to the settings you configured.
Remember that making changes to the Windows Registry can impact your system's behaviour, so it's recommended to create a system restore point or back up your registry before proceeding.

Use Win+L key
The Win+L key combination is a quick and easy way to lock your laptop screen without putting it to sleep. This method is available on Windows 10 and 11. The "Windows" keyboard key is usually found between the CTRL and ALT keys on most keyboards.
Using this key combination instantly locks your screen, allowing you to visually verify that your laptop is secure before shutting the lid. This is especially useful if you want to make sure that your laptop is locked when you are stepping away from it. This method also ensures that no malfunctioning processes or background apps can prevent your laptop from locking, which could be a potential issue with auto-lock or sleep modes.
Additionally, the Win+L key combination provides an extra layer of security. You can set up an auto-lock or screen saver to activate after a certain period of inactivity, and by using Win+L, you can manually lock your screen whenever you want. This is helpful if you need to step away from your laptop before the auto-lock timer goes off.
However, it is important to note that some laptops may have hidden settings that cause the laptop to go into standby or sleep mode very quickly after locking the screen. This issue has been observed on certain Dell laptop models, where the screen turns off within 2 minutes of locking, although an LED indicator shows that the laptop is not sleeping. If you encounter this issue, you can try disabling 'connected standby' by using the command "powercfg /a in cmd" to switch back to traditional standby mode.
