Asus ROG Strix G16 (2024) laptop - high power consumption in sleep mode (10-80 watts)

[Testset1251]

So I recently bought Asus ROG Strix G16 (2024) laptop but I noticed a high power consumption in sleep mode (10-80 watts).

It jumps periodically from 10 to 80 watts but it should only power RAM and some other stuff, but 20+ watts is too much...

Sometimes it can be ~5 watts for while but still increases from time to time 30--56+ wats

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.
The hypervisor does not support this standby state.

Is it supposed to work like this on Asus laptops?

I have ROG Strix G17 (2023) G713PV 7845hx and 4060 when i set up closing lid that it should sleep it does not untill i disconnect power cable, many times i found that it was dead after i took it from my bag, or it does not go to sleep at all, not only that, i cannot get audio work on windows 10 because there are no drivers for it so i`m stuck using windows 11, then screen sometimes flickers i believe its a driver issue cause it is a completely random thing, after i installed "recommended" nvidia driver randomness got infrequent, which is mind blowing that it cannot get proper latest geforce experience driver and call it a day, then one time it got stuck no cooling, i`m guessing armory crate did this, and it overheated and turned off, i rebooted same thing, then uninstalled armory crate, fans came back after restart, conclusion is i`m never going to buy asus laptop again, yes they are cheap, but i seriously cannot believe how bad it is.

It's not only powering the ram, cpu is still doing stuff. Windows has this thing called modern standby also known as S0 sleep. All windows laptops have it and when you put the laptop in sleep, it enters a "low power stage". Depending on being connected to the charger or not, it will go in S0 network connected or S0 network disconnected. With network connected it can download updates and stuff, receive VoIP calls etc. Also modern standby S0 is what makes that instant wakeup from sleep possible. Your laptop is probably doing something in the background when you checked like getting updates.

The old sleep state that has only ram active is called S3 sleep. Most laptops don't even support it in their firmware anymore (Asus is one of the few that still does) but you need to do some work in windows if you want it instead of S0.

from the comment https://www.reddit.com/r/ASUSROG/comments/1cpgtrd/comment/l3lhdhl/

And the solution I have tried to disable S0 mode:

reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0 (in Terminal with admin rights of course)

I rebooted the laptop (mandatory to make changes) and it seems changed the mode to S3:

The following sleep states are available on this system:

Standby (S3)

Hibernate

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.

Hybrid Sleep

The hypervisor does not support this standby state.

p.s. if for someone it won't work, use reg delete "HKLM\System\CurrentControlSet\Control\Power" /v PlatformAoAcOverride /f to undo changes

Sleep mode options didn't disappear after this as it was happening for some other laptop owners (I believe their firmware didn't support S3)

And it actually works fine, so RAM, USB hub with separated power supply connected, and a external monitor in idle mode only use 0.5 W now:

 

Though it works but only if I put the laptop to sleep manually using "Right click on Windows/Shut down or sign out/Sleep", in all other cases like automatic Windows timeout sleep, power button on the laptop or "ALT+F4 / Sleep" make the laptop sleep and instantly wakes it up for some reason. Why does it work differently? Is there any solution?

Update SOLVED:

I found the reason why laptop automatically wakes up right after it goes in sleep mode (in cases like automatic Windows timeout sleep, power button on the laptop or "ALT+F4 / Sleep") - external usb keyboard, though external usb mouse works fine and doesn't cause this issue, so I just disabled the option in power management of the external keyboard to wake the laptop, but I can still use a mouse or built-in laptop keyboard anyway to wake it up. So now it works in all cases! So weird... when I previously "Right click on Windows/Shut down or sign out/Sleep" it wasn't the issue for automatic awakening 🙂

It looks as it is the same as hibernation or is it different? Thanks!! 

[Testset1251]

what do u mean? hibernation saves data to the disk and should not use power

Thanks for providing info about it, if i’m not wrong when the power indicator starts blinking it means it’s fully slept (ram only)
