Windows 10 computer exits sleep mode on its own

Thank you for your detailed explanation and sorry for the delay, it took some time to test things and I didn't use my computer a lot this month. I applied a few of the advices, especially those related to the power management settings, it seemed to help a bit, but did not solve the problem.

This night again my computer exited sleep on its own, so I used powercfg -lastwake and got the exact same thing as here : https://answers.microsoft.com/en-us/windows/forum/all/computer-wakes-from-sleep-automatically-every/12b32ace-fb6b-4ab9-9aa4-3f03446a5a94?page=2

The first answer is not good since, like many in the answers below, I have no****"Universal Orchestrator Start" listed in the Task Scheduler.

So I went with disabling "Allow wake timers" in advanced power plan settings. I thought I already did that, but either I was wrong, either Windows re-enabled it on its own ... Hoping this will work.

This is really tiring ... Is there no way to report to Windows engineers that, when people set their computer asleep, they want it to stay asleep ? That should be common sense. And the fact that it seems there is no way to easily fix this, that there are hundreds of possibilities for the source of the problem ... And with the scale of Windows, I can't imagine the power waste that it causes worldwide.

Hi Lucas. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Guardian Moderator here to help you.

I prefer Hibernate to kick in within an hour after Sleep, as it's a deeper sleep that actually powers off the PC, yet still saves everything that you left open and replaces it when you power back on, much faster than a normal startup. I don't think Updates can bother Hibernate like Sleep.

But let's make sure that's what's happening.

I will give you all possible fixes for Sleep, based on ten years troubleshooting it almost daily. If you need help performing any step just ask back:

First confirm you have the Sleep options configured correctly as shown here:

You might want to try Hibernate to succeed Sleep, or use Hibernate in place of Sleep - it's just a deeper sleep that actually powers off because desktop stored in RAM during sleep is written to hard drive hiberfile then powered off.

Most Sleep problems are caused by the Display driver, so try updating yours from the PC or Device maker's Support Downloads web page for your full model number, Serial Number or Dell Service tag. While there make sure you have the latest BIOS, Chipset, Network, Sound, USB and all other drivers by comparing those posted for download with the version and date of the corresponding ones in the Device Manager.

If that doesn't help then in Device Manager on Display device Driver tab choose Roll back, Uninstall (then restart to reinstall) or try another one previously installed at Device Manager>Display adapter>Driver>Update Driver>Browse>Let me pick.

In addition there are steps here to specifically troubleshoot Sleep mode problems: http://www.makeuseof.com/tag/fix-windows-10-sle...

What I do is go into Advanced Power options and set Display and Sleep to 1 minutes, Hibernate to 2 minutes, then after completing each step restart the PC and observe what happens for 3 minutes.

Also did it previously work? Do you have a System Restore point from when it did?http://home.bt.com/tech-gadgets/computing/how-t...

This may have been caused by Windows Updates. Check which Updates were installed right before the problem began, and if necessary uninstall them from Settings > Update & Security > Windows Update > Installed Update History.

You can also try to roll back using System Restore to a point before this began: http://home.bt.com/tech-gadgets/computing/how-t...

Then if an Update reinstalls and causes the same problem uninstall or roll it back again, then immediately hide it using the Hide Updates tool from Method Two here: https://www.askvg.com/fixing-windows-10-automat...

If nothing else helps you can run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This reinstalls Windows in about an hour while saving your files, apps and most settings, solves many problems while also bringing it up to the latest version 1903 which you need anyway and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m....

I hope this helps. Feel free to ask back any questions and keep me posted. If you'll wait to rate whether my post helped you, I will keep working with you until it's resolved.
