Intel i7-12700H laptop Modern Standby battery drain.

[voldemarz]

I have a Tuxedo InfinityBook Pro 14 gen7 laptop with Intel i7-12700H running Windows 11 24H2. Modern Standby / s0 sleep has never properly worked, am regularly getting drained battery in just couple hours of sleep, occasionally random wakes. When worst cases of battery drain happen, powercfg sleepstudy points to SOC being the problem.

Microsoft support is useless, manufacturer always pointed to "background processes" being the problem. So am I trying to see if any help can be found here.

OS is Windows 11 24H2 (26100.4652), DISM, SFC report no issues, drivers are up to date. UEFI firmware is up to date, even tried to reflash it. Most of non-essential startup apps and background processes are disabled, wake timers are disabled, ability to wake disabled for all devices, automatic Windows Updates are disabled.

I attached Intel System Support Utility output and powercfg sleepstudy report and a recent case from September 1st when got 40% battery drained in 5h. I had just rebooted the laptop, opened web browser with 3 windows and put the laptop to sleep before the drain issues occurred. I have set up WPR to start trace before sleep and stop after wake. The trace from September 1st can be downloaded here (too large to attach) https://mega.nz/file/sZwFAZjC#8LJjQVkqa_x_mp9Nr_5Fq40Mik037YErjX43CCbt_jY

 

Please don't suggest to use hibernation, I want the instant wake from sleep.

You need to talk to the manufacturer of your device regarding THEIR BIOS.

This is not an Intel processor issue.

I have contacted them multiple times. Their stance is that they do not see any problems in their testing, so it must be my software causing problems.

This could be Intel SOC issue as implied by sleepstudy report, which could perhaps be addressed with some chipset driver, hence posting here. Or perhaps someone can spot in WPR trace what could be preventing hardware DRIPS / low power state.

Forgot to mention that I have disabled "connected standby", though not convinced it is really respected. This is "powercfg /a" output:

> The following sleep states are available on this system:
> Standby (S0 Low Power Idle) Network Disconnected
> Hibernate
