When a user creates a power policy setting by using the Group Policy Management Console (gpedit.msc), which establishes a sleep or hibernation timeout of less than 60 seconds, the kernel does not accept this change, and it sets the timeout to 60 seconds. This is a known issue that exists, which allows the power policy settings to be changed by the user to values below the 60-second threshold even though these settings will not be used by the kernel. The kernel has a fixed minimum value of 60 seconds for sleep and hibernation timeouts. To resolve this known issue, ensure that sleep and hibernation timeouts are set at a minimum of 60 seconds.
