Windows 8.1 Mini TIPS (101) Disable sleep release by automatic maintenance | Mynavi News Mynavi News Mynavi
"Automatic maintenance" added from Windows 8 is a function that performs a series of conservative treatments, such as improving the disk fragment (fragmentation) when the PC is waiting at the specified time.The outline and settings were described in the 76th, but there are some situations where the sleep status of the PC is released in the middle of the night.This time, I would like to introduce how to control sleep release by automatic maintenance.
The execution time of automatic maintenance in Windows 8.1 is 3:00 on the morning (midnight) every morning.If the PC is operated in sleep without turning off the PC, the maintenance is automatically executed, so it is more convenient to use it as it is.However, there are many users who feel harmful, such as waking up with the sound of the PC starting.
When automatic maintenance begins, various maintenance treatments such as discs and defragments are performed. |
There are two checkpoints for sleep release.The first is automatic maintenance settings.Sleep removal is not executed by turning off the prepared "Available computers to sleep by scheduled maintenance".
Click/tap in order to "Action Center" icon in the notification area → "Open the action center" |
Click/tap "Maintenance" and click/tap "Change Maintenance Settings" in "Automatic Maintenance" |
If you turn off "Absent up to sleep by a scheduled maintenance", it will be invalidated by automatic maintenance. |
Another is the power plan.In the detailed setting of the active power plan, there is an item called "Permit of the Sleep Release Timer", but in the case of a desktop PC, in the case of a battery -driven mobile device, "Battery -driven" "Connect to a power supply".], You may select "Disable" according to each condition.
Press the "Win"+"R" key to start "Execute with the file name", enter "Control /Name Microsoft.powerOptions" in the text box, and click /tap the "OK" button. |
Click/tap "Change Plan Settings" in the power plan in use |
Click/tap "Change Detailed Power Supply" |
"Sleep" → "Sleep release timer permission" is expanded in order, and "Disable" is selected from the drop -down list of "Battery Drive" and "Connect to the Power Source".Finally, click/tap the "OK" button |
Keep in mind that the former has an automatic maintenance -specific sleep release setting, and the latter has an impact on other functions because it is a sleep release setting of Windows 8.1 as a whole.
If Windows does not detect an ACPI Wake Alarm device, it uses RTC (Real Time Clock) to control sleep.If the previous "Sleep Release Timer permission" is valid, it is a mechanism to program the sleep release event with RTC before the PC enters the sleep/pause state, and realize action such as automatic maintenance.
When the ACPI Wake Alarm device is detected, the "ACPI Wake Alarm" is lined up in the "system device" of the "device manager".There was no corresponding device in my environment |
The "%SystemRoot%\ System32 \ Drivers" folder has a device driver "ACPITITIME.SYS". |
Still, if the sleep is released, there is a high possibility that there is another cause.So, next time, I will introduce the procedure to explore the cause of sleep release.
