Windows keeps waking up laptop from Modern Standby
Hi,
On my new laptop (it's in my specs) that came with 2004 preinstalled so far I have figured out that updating it to 20H2 has brought back the option to enter(in an elevated command window, and reboot after that) to revert from Modern Standby, or S0 Low Power Idle compatibility back to traditional-old S3 so I am using that for my temporary working solution.Code:reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0
There's no option to disable Modern Standby in BIOS, and disabling Wake Timers also didn't help. And there wasn't even a Power Management tab to be found in the Intel WiFi 6 adapter's hardware properties panel until finally I got tired of getting frequent wakeups and decided to use the above registry hack.
Running on 20H2, before the registry hack here's what it gave me:
After the registry hack with reboot, here's what I got instead:Code:C:\Windows\system32>powercfg waketimers Timer set by [PROCESS] \Device\HarddiskVolume3\Windows\SystemApps\Microsoft.Windows.StartMenuExperienceHost_cw5n1h2txyewy\StartMenuExperienceHost.exe expires at 4:00:00 on . C:\Windows\system32>powercfg devicequery wake_armed NONE C:\Windows\system32>powercfg lastwake Wake History Count - 0 C:\Windows\system32>powercfg requests DISPLAY: None. SYSTEM: None. AWAYMODE: None. EXECUTION: None. PERFBOOST: None. ACTIVELOCKSCREEN: None. C:\Windows\system32>powercfg a The following sleep states are available on this system: Standby (S0 Low Power Idle) Network Connected Hibernate Fast Startup The following sleep states are not available on this system: Standby (S1) The system firmware does not support this standby state. This standby state is disabled when S0 low power idle is supported. Standby (S2) The system firmware does not support this standby state. This standby state is disabled when S0 low power idle is supported. Standby (S3) This standby state is disabled when S0 low power idle is supported. Hybrid Sleep Standby (S3) is not available.
Next, I unchecked the "allow this device to wake the computer" for the WiFi adapter, and I also turned the Wake Timers back on, just to see how stuff will behave. So far it hasn't woken up in a while.Code:C:\Windows\system32>powercfg a The following sleep states are available on this system: Standby (S3) Hibernate Hybrid Sleep Fast Startup The following sleep states are not available on this system: Standby (S1) The system firmware does not support this standby state. Standby (S2) The system firmware does not support this standby state. Standby (S0 Low Power Idle) The system firmware does not support this standby state.

Is there anything I could try to get Modern Standby to work properly without it waking itself back up for no good reason, usually within the next hour?
