Windows 10: Putting computer to sleep causes it to crash when logged in to my account

Hi there. Recently when I have been putting my computer to sleep the monitor turns off but the computer stays onfans etc all still on. I then try to wake it and I cant so I have to do a hard reset. So something is causing my computer to crash before it goes to sleep. I have tried logging out of my account and then putting it to sleep and this works fine so it must be something which is running in my account which is causing the problem. Is there any way I can find out what is specifically causing this problem? Many thanks, Dannyps. I have updated all of my drivers and this did not solve the

Trouble Putting PC to Sleep

I finally determined what the cause of my PC waking up right after I invoke sleep function Start > Power > Sleep. I recently purchased a Velocifire wireless (2.4ghz) keyboard that also comes with a USB cord so it can be used in corded mode. When used in corded mode, sleeping the PC is not a problem. When I use the wireless dongle, the PC refuses to sleep for more than a second. So, the wireless mode of this keyboard is what triggers the problem. In addition to the things I've tried in my original post, here are the results of some suggestions you guys made:

• Created a new fake user and logged in under than user. Same behavior.
• Started PC in Safe Mode. Unfortunately, in Safe Mode sleep functions are limited to the monitor and hard drives. Nothing to put the PC to sleep.
• Tried going into sleep via Alt + F4. Same behavior.
• powercfg -a reports S3 is active on my system.

There are no obvious irregularities in Device Manager. The dongle shows up under USB Serial Bus Controllers as a USB Composite Device.

• General Tab says "This device is working properly".
• In Driver Tab, I tried searching for a better driver, but Windows says there is no better driver.
• There is no Power Management tab.

So as it turns out, all of things I've tried appear to have been a waste of time as it was not addressing the wireless function of the keyboard. I contacted the manufacturer and they suggested that I delete the USB Composite Device entry, re-boot and re-insert the dongle. However, that did not change inability to sleep the PC.

Any other ideas?

 

Computer wakes from sleep immediately after putting to sleep

Hi,

Thank you for writing to Microsoft Community Forums.

I understand that the computer wakes up immediately after putting to sleep.

There could be several reasons for the computer not going to sleep mode. To determine which device is causing this, we can run a simple command and check the reason why the computer woke up from sleep mode. To do this refer the steps mentioned below:

1. Type command prompt in the
   search bar on the Taskbar.
   
2. Right click on the command prompt icon and select
   Run as administrator.
   
3. Now, paste the following command and hit Enter:
   powercfg lastwake.
   
4. Share the results of the command.
   

The above command should let us know the device that is preventing the computer going into sleep mode.

Let us know the results and we will help you further.

BSOD/crashes occur when computer sleeps

Perhaps I have overlooked some suggestions. Other than disabling sleep, which I can try, are there others?

I am confident my Power settings are basic and not causing this.

Regarding sleep, which is an essential function of a computer in my mind, if disabling it prevents the crashes from occurring that doesn't really fix the problem it just masks the symptom.
