Scheduled task to wake computer from sleep not working on Windows 10

[DrBeaker]

Is anyone else finding any issues with computers running Windows 10 not waking from sleep?

 

Running Windows 10 Pro x64 1903. No drivers missing etc.

 

I've set a scheduled task to wake the computer from sleep, but it doesn't seem to be working on Windows 10. I can get the machine to sleep no problems. But anything I schedule to wake the machine from sleep via task scheduler, doesn't seem to work. The machine still sits in sleep mode and does nothing. Waking with a press of the keyboard, works fine - no issues. Yet task history shows the event has "successfully completed".

 

I tried this in Windows 7 (in 2018, way before the recent support cut-off date) and it worked fine, no problems. I could get it to sleep and wake on schedule. It only seems to be Windows 10 that it's refusing to work on.

 

Tried with:

- Run only when user is logged on

- Run whether user is logged on or not

- Run with highest privileges

 

Settings

- Disabled Hibernation

- Fast Startup disabled

- Set to not ask for password when resuming from sleep

 

The wider web seems to be full of the same issues from 2015 up until recently. Has anybody else encountered this problem?

Just put it out there have you considered the monitor?

 

Try Replacing the monitor?

 

I have a number of HP monitors with weak / knackered inverters and find that the monitor won’t come on after going to sleep if it has been sleeping for a while.

 

Only turning the computer off and back on again as well as unplugging the monitor holding the power button down for a while whilst plugging the monitor back in to work.

No afraid not.

 

Tried it on a few different model of computers and with different models of screens (using VGA and HDMI connections) with the same result. Sleep works perfectly. The wake from sleep does nothing.

 

- Pressing the power button on the computer resumes it from standby

- Pressing the wired keyboard resumes the computer from standby

- Pressing the wireless keyboard resumes the computer from standby

 

- Tried running as various local users/system/inbuilt accounts - no result.

 

Seems like a common thing online for a few years, but still seems to be an issue - there's posts as far back as 2015 and as recently as 2018/19 with seemingly no fixes. But it's going to put a bit of a spanner in the works for some things I'd got planned with this setup. But it worked with no problems on Windows 7.

 

I can always use WoL or BIOS boot timings to boot the computer, but that's not what I was trying to accomplish really.

Have you enabled wake timers?

Hi, Yep wake timers are enabled. Still makes no difference.

 

Tried it on a fresh build on Friday and nothing. Tried it on a device at home and nothing either.

Are the PCs on separate VLANs?

No this is a local scheduled task set on the local machine using the local admin account. No internet/network connection needed for that.

 

I'm looking to have it locally wake and go to sleep via these local tasks.

 

Just no joy with the wake task.
