Lenovo LOQ 15ARP9 – System Fails to Resume from Suspend (s2idle) on Linux

Hello,

I am experiencing a persistent suspend/resume issue on my Lenovo Lenovo LOQ 15ARP9 while running Linux. The system enters suspend successfully, but it fails to wake up properly and requires a hard power-off.

System Specifications

  • Model: Lenovo LOQ 15ARP9
  • CPU: AMD Ryzen 7 7435HS
  • GPU: NVIDIA GeForce RTX 4060 Laptop GPU (discrete GPU only, no integrated GPU)
  • RAM: 8 GB
  • Display: 1920×1080 @ 144 Hz
  • Storage: ~1 TB (Btrfs)

Software Environment

  • Distribution: CachyOS (Arch Linux based)
  • Kernels tested:
    • linux
    • linux-zen
    • linux-cachyos
  • Desktop Environments Tested:
    • Hyprland
    • KDE Plasma
  • Display Protocols: Wayland and X11
  • Graphics Driver: Proprietary NVIDIA driver (latest available version)
  • Init System: systemd

Problem Description

The laptop enters suspend normally, but when attempting to resume:

  • The screen remains completely black.
  • Keyboard backlight may turn on, but the system appears frozen.
  • No SSH access is possible.
  • The machine does not respond to input.
  • A hard power-off (holding the power button) is required.

This indicates a full system lockup rather than only a graphics issue.

Power Sleep Information

cat /sys/power/mem_sleep

Output:

[s2idle]

Only s2idle is available; deep sleep is not supported on this system.

Troubleshooting Steps Already Performed

BIOS / Firmware

  • Updated BIOS to the latest version.
  • Disabled Secure Boot.
  • Disabled Fast Boot.

Kernel Parameters Tested

  • mem_sleep_default=s2idle
  • nvidia.NVreg_PreserveVideoMemoryAllocations=1
  • nvidia.NVreg_TemporaryFilePath=/var/tmp

NVIDIA Power Management Services

sudo systemctl enable nvidia-suspend.service
sudo systemctl enable nvidia-resume.service
sudo systemctl enable nvidia-hibernate.service

Additional Testing

  • Multiple kernels tested.
  • Multiple desktop environments tested.
  • Both Wayland and X11 tested.
  • Issue persists under all configurations.

Additional Observations

  • The system appears to hang completely.
  • This is a discrete-GPU-only configuration (no integrated GPU).
  • Since only s2idle is available, traditional deep sleep cannot be tested.
  • Similar suspend/resume issues have been reported on AMD CPU + NVIDIA GPU laptops.

Questions

  1. Has anyone with a Lenovo LOQ 15ARP9 managed to get suspend/resume working reliably?
  2. Are there known workarounds for systems that only support s2idle?
  3. Is this a known issue involving AMD CPUs and NVIDIA discrete GPUs?
  4. Are there any upstream Linux patches or firmware fixes in progress?

If any logs are needed, I can provide:

  • journalctl -b -1
  • dmesg
  • lspci -k
  • inxi -Fxxx

Any suggestions or experiences with this model would be greatly appreciated.
