DGPU Disconnecting BUG

[High-RaXe]

Version

2.26.1

OS

Windows 11 Pro 24H2

Device

LOQ 15AHP9

BIOS version

NZCN27WW

What is wrong?

So the DGPU won't disconnect on Hybrid-auto mode when i turn on the laptop on battery but it does disconnect automatically upon removing the AC adapter.
This issue only persists in LLT since using Vantage fixed this issue instantly
The DGPU WILL disconnect when i switch the modes like switch to IGPU mode and switch back.

What did you try already?

I have DDU'ed drivers including Nvidia,AMD and Lenovo OEM drivers but no luck, have also disabled fast startup.
Kept every single application terminated..

How to reproduce the bug?

All you need to do is Keep yourself in Hybrid-auto mode and turn on the laptop on battery.

What is the behavior that you expected?

Nothing out of the ordinary besides the DGPU not disconnecting

Same issue with (Legion 7 16IRX9) with nvidia drivers 576.xx+.
Long gGPU disconnection or never when user switches iGPU.
Also, GPU sensors are buggy 40C, freq 405mhz.

Legion 7 16IRX9
Bios: NSCN39WW
GPU - Nvidia RTX 4060
LLT 2.26.1
Windows 11 Pro 24H2

Reproducible:

• nvidia drivers 576.xx+
• Did not check older versions of LLT.
• Unplug AC or/and force switch to IGPU mode

Sometimes, the laptop gets hot in sleep mode on battery.

I am still stuck with Nvidia drivers 572.83 where the GPU mode works in a more stable way.
And sensors 35C, no info about frequency
