When a computer or application is put into sleep mode, it is inactive or disabled. This means that it will not update automatically until it is reactivated. For example, Windows 10 PCs do not update when in sleep mode, and will only wake up from sleep to install updates if the user has not disabled this setting. Similarly, Android devices will not update apps that have been put into deep sleep, which is a feature that automatically disables unused apps.

Windows 10 updates during sleep mode
When a Windows 10 PC enters sleep mode, it saves the current system state and stores that information in memory. Typically, Windows 10 will not install updates while the PC is asleep. However, there is a feature called "wake timers" that can pull the PC out of sleep mode to install updates.
Wake timers act as an "alarm clock" for your PC, allowing it to wake up from sleep mode at a specified time to install updates. This feature can be disabled to prevent the PC from waking up during sleep mode. On a desktop, you can disable wake timers by going to the "Sleep" settings, expanding the "Allow Wake Timers" option, and selecting "Disable" in the drop-down menu. On a laptop, you can disable wake timers by selecting "Disable" for both the "On Battery" and "Plugged In" settings. Disabling wake timers ensures that your PC will not wake up to install updates while in sleep mode.
It's important to note that users can schedule "active hours" to prevent Windows 10 from installing updates at inconvenient times. By scheduling active hours, users can ensure that updates are installed during their preferred time windows. Additionally, on a laptop, wake timers may be automatically disabled when the device is running solely on battery power. This prevents the laptop from waking up inside a bag, installing updates, and potentially overheating.
While Windows 10 typically does not install updates during sleep mode, there may be exceptions or specific configurations that allow updates during sleep. It is recommended to review the update settings and configure them according to your preferences to ensure your PC behaves as expected during sleep mode.

Scheduling active hours on Windows 10
Windows 10 provides the means to stop automatic updates while your computer sleeps. Typically, users schedule "active hours" to prevent Windows 10 from installing updates at inconvenient times. Active Hours is a Windows 10 feature that lets you inform your computer when you're most likely to be using it. This prevents your computer from automatically rebooting after a Windows Update during your specified active hours.
To schedule Active Hours on Windows 10, follow these steps:
- Go to Start, then select Settings > Update & Security > Windows Update.
- Select "Change active hours."
- Turn on "Automatically adjust active hours for this device based on activity."
- Select "Save."
- If you want to manually adjust your active hours, go to Start, then select Settings > Update & Security > Windows Update again.
- Select "Change active hours" and then choose the "Change" option next to your current active hours.
- Select the start and end times for your active hours.
You can also use the Windows Registry Editor to adjust your active hours. Here's how:
- Open the Registry Editor by searching for "regedit" in the Start menu or Run dialog box.
- Navigate to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsUpdate\UX\Settings.
- Double-click on "ActiveHoursStart" and set the desired start time for your active hours.
- Double-click on "ActiveHoursEnd" and set the desired end time for your active hours.
Keep in mind that Active Hours only allows a maximum of 18 hours to be set. Additionally, you cannot set multiple times within a day or change weekend times using this feature.

Preventing Windows 10 from waking up from sleep mode
Typically, users schedule "active hours" so that Windows 10 does not install updates at inconvenient times. When a Windows 10 PC goes into sleep mode, it saves the current system state and stores that information into memory.
However, Windows 10 does provide the means to stop automatic updates while it sleeps. Here are some ways to prevent your Windows 10 PC from waking up from sleep mode:
Disable Wake Timers
Open the Start menu, search for "Edit Power Plan," and click Change Advanced Settings in the Edit Plan Settings window. Head to Sleep > Allow Wake Timers and change Battery and Plugged In to Disabled. Repeat this process for all your power plans in the drop-down menu at the top.
Disable Windows Update Power Management
If you have a Pro or Enterprise edition of Windows 10, you can access the Group Policy Editor. With Local Group Policy Editor open, head to Computer Configuration > Administrative Templates > Windows Components > Windows Update, then double-click Enabling Windows Update Power Management and set it to Disabled.
Change Automatic Maintenance Settings
Open the Start menu, search for "Automatic maintenance," and click Change Automatic Maintenance settings to open the Control Panel. From this menu, you can either change the time this runs or prevent it from waking the computer by unchecking the "Allow scheduled maintenance to wake up my computer" option.
It's important to note that random wakeups can be challenging to solve, and new programs, hardware, or Windows updates may cause the issue to resurface.

Updating 'deep sleep' apps on Android
Updating deep sleep apps on Android
Deep sleep apps on Android refer to apps that have been put into a state of hibernation and are not actively running in the background. When an app is in deep sleep, it is essentially disabled and inert, meaning it won't show up in the app list and won't receive automatic updates. This can be a problem if you want to keep your apps updated, as the Google Play Store primarily checks for updates on apps that are actively running or have been recently used.
To update deep sleep apps on Android, you can try the following methods:
- Manually update each app: Remove the app from the 'Deep Sleep' list, which has to be done individually for each app. Once removed, the app will start receiving updates again, although it may take some time for the updates to be detected and installed.
- Use a third-party app: Install a third-party app like Runner, which is specifically designed to update deep sleeping apps on Samsung devices running Android (One UI). Runner launches all user-installed (non-system) deep sleeping apps, allowing you to check for app updates in the Play Store. Once the updates are installed, you can turn off your phone's display, and the apps will be put back into deep sleep.
- Disable deep sleep: If you want your apps to always receive updates, you can disable the deep sleep feature for individual apps. This will allow the Play Store to detect and install updates for those apps automatically. However, this may defeat the purpose of putting apps into deep sleep in the first place, which is to prevent them from running in the background and using system resources.
It's important to note that the behaviour of deep sleep apps may vary depending on the Android device and version you're using. Some users have reported that their Samsung devices running Android 12 and above have different experiences with deep sleep and updating apps.

Windows 10 laptop wake timers
When a Windows 10 PC goes into sleep mode, it saves the current system state and stores that information into memory. Typically, Windows 10 does not install updates while the PC is asleep. However, there is an option in Windows 10's advanced Power Options called "Important Wake Timers Only" that allows wake timers to interrupt sleep. These are a new class of wake timer that includes things like critical updates and reboots after a Windows update that requires one. They supersede all other settings and can only be prevented if the computer is off or if the timer is disabled in the task scheduler.
Wake timers are timed events that wake the PC from sleep and hibernate states at a specific time. For example, a user might want to back up their system at 1 am every day but not leave their machine on all night. In this case, a wake timer would wake the PC up to prepare for the scheduled backup.
To disable wake timers on a Windows 10 laptop, follow these steps:
- Open the advanced power settings of the power plan you want to enable or disable wake timers for.
- Expand open Sleep and Allow wake timers.
- Select "Disable" for both "On Battery" and "Plugged In" options.
Disabling wake timers will ensure that your laptop does not wake up to update while in sleep mode, which can be helpful if you want to prevent overheating or conserve battery life.
