System does not wake from hibernation at scheduled time

Question

Hello,

I'm using Windows 10 Pro, and it goes in hibernate at 8:00 pm every night. In the morning, Windows task scheduler tries to wake the system to run a task at 8:00 am, but the system wakes at around 8:08 am. As a result, the task fails with the following message.

• Task Scheduler did not launch task "Wake" as it missed its schedule. Consider using the configuration option to start the task when available, if schedule is missed.

I'm wondering why it takes so long time to wake from hibernation. I understand that it takes a little time to wake from hibernation, but it takes roughly 1 minutes to wake from turned off state, so I feel 8 minutes is too long.

I understand that the task is started again if I enable the setting of "Run task as soon as possible after a scheduled task is missed", but I would like to start the task on time.

Does anyone know why the resume from hibernation is so late? Can I improve the situation?

Thanks,
ytnk

Hello

Thank you for your question and reaching out. I can understand you are having issues related to Hibernate Task scheduler.

Open "Control Panel -> All Control Panel Items -> Power Options -> Edit Plan Settings" for the power plan u are using. Then select "Change advanced power settings". Next go to "Sleep -> Allow wake timers" and enable them there.

You can also Schedule the same from BIOS which is also good approach,

Hi,

System power state S4, the hibernate state, is the lowest-powered sleeping state and has the longest wake-up latency. To reduce power consumption to a minimum, the hardware powers off all devices.

Details of the intermediate sleep states can vary depending on how the manufacturer has designed the machine. For example, on some machines certain chips on the motherboard might lose power at S3, while on others such chips retain power until S4. Furthermore, some devices might be able to wake the system only from S1 and not from deeper sleep states.
