The game forces Windows into sleep mode after some minutes afk.

Nope single player game multiplayer turned off. I would like to put myself in to the cryo pod while I am afk for things like the bathroom or dinner. Now I have to tab out of the game or it will shut my PC down.

I have followed all of these steps in order exactly as requested here is the log file

here is the relevant windows event viewer log...

This only happens in space engineers and only while paused or in some kind of cockpit\cryochamber. For some reason the game is telling windows that the computer has gone completely idle after 5 minutes in situation.

Hello Medullan,

Thanks again for the detailed follow-up. Since the previous troubleshooting steps didn’t resolve the issue, there’s one more change that may help. This is a safe system-level adjustment that often provides a permanent fix. But please note that it involves editing the Windows registry. We recommend creating a restore point before making changes, just to be safe.

Step 1 - Check if Windows is using Modern Standby

Open a Command Prompt and type:

powercfg /a

If you see “S0 Low Power Idle (Modern Standby)” listed, your system is using Modern Standby. This mode can sometimes trigger idle timeouts even when applications are running in the background (such as paused Space Engineers sessions).

Step 2 - Disable Modern Standby via Registry

1. Open Registry Editor (press Win + R, type regedit, and press Enter).
2. Navigate to:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
3. Inside the Power key, look for a DWORD value named:
   PlatformAoAcOverride
   - If it already exists, double-click it and set the value to 0.
   - If it doesn’t exist, right-click in the right pane → New → DWORD (32-bit) Value → name it PlatformAoAcOverride → set the value to 0.
4. Reboot your PC.
5. Run powercfg /a again, S0 Modern Standby should no longer be listed.

After this, Windows will use the traditional S3 sleep mode instead of S0 Modern Standby. This prevents idle timeouts from interrupting the game, allowing Space Engineers to remain running (even when paused or in a cryochamber).

Please let us know if this resolves the issue for you.

Kind Regards

This does not resolve this issue for me. S0 Modern Standby is not a bug it is a feature of windows. No other software I use triggers it only your game. That is a bug with Space Engineers and cannot be appropriately resolved by editing my windows registry. If you are asking me to do this edit to confirm that this is the cause of the bug in your software I can do that but then I will change it back to the correct setting and expect you will fix the bug with your software. I don't believe you actually need me to verify this is the bug you have the information you need to reproduce the issue yourself now and should be able to verify this on your end. RegEdit is a workaround not a bugfix. While I appreciate you explaining the workaround it should be directly stated by you that this is just a workaround, and that now that you are aware of the steps necessary to reproduce this bug you will work on fixing it. Either way I appreciate your time, please let me know if you do in fact need my help verifying the cause of the bug and/or let me know that you have added the bug to the kill list and will be working on it as soon as is reasonable.

Hello Medullan,

To provide some clarification, the suggestion we shared was intended as a workaround, not a permanent solution, for cases where Windows unexpectedly enters standby mode. This adjustment has resolved similar issues in some setups, which is why we recommended giving it a try. We apologize if it was perceived as a definitive fix.

To help us investigate this further and ensure we have the right details, could you kindly confirm a few points:

• After applying the workaround, did the behavior in Space Engineers change at all (e.g. did it prevent standby while paused/cryo, even temporarily)?
• Did the registry change affect any other programs or system behavior on your laptop?
• When this happens, is the system running on AC power, battery, or both?
• Could you also share your MSI BIOS/firmware version, and whether you have any power/standby options enabled or disabled there?

Your input here would be very valuable in helping us narrow down the reproduction steps. Thank you again for the time and detail you’ve provided, it is much appreciated.

Kind Regards,
