NVRM: failed to get target temp from SBIOS / failed to get platform power mode from SBIOS on RTX 4050 Laptop GPU

Hello,

I am seeing the following NVRM messages on an Acer Nitro ANV15-51 laptop with an NVIDIA GeForce RTX 4050 Laptop GPU:

NVRM: GPU0 nvAssertOkFailedNoLog: Assertion failed: Invalid data passed [NV_ERR_INVALID_DATA] (0x00000025) returned from PlatformRequestHandler failed to get target temp from SBIOS @ platform_request_handler_ctrl.c:2174

NVRM: GPU0 nvAssertOkFailedNoLog: Assertion failed: Invalid data passed [NV_ERR_INVALID_DATA] (0x00000025) returned from PlatformRequestHandler failed to get platform power mode from SBIOS @ platform_request_handler_ctrl.c:2117

System information:

  • Laptop: Acer Nitro ANV15-51
  • BIOS: V1.60, release date 04/08/2026
  • OS: Pop!_OS 24.04
  • Kernel: 7.0.11-76070011-generic
  • NVIDIA driver: 595.84
  • GPU: NVIDIA GeForce RTX 4050 Laptop GPU
  • Graphics mode: hybrid
  • Runtime D3: Enabled (fine-grained)
  • Notebook Dynamic Boost: Supported
  • S0ix Power Management: Platform Support: Not Supported

The GPU initializes and works. Runtime D3 is enabled. However, these NVRM assertions appear on every boot.

I have already updated the Acer BIOS from V1.52 to V1.60, but the messages still persist.

I have attached nvidia-bug-report.log.gz generated after reproducing the issue.

Similar symptoms on ASUS hardware — sharing findings in case they help.

Hardware:

  • ASUS TUF Gaming A15 (FA507NV)
  • AMD Ryzen 7 7735H
  • NVIDIA GeForce RTX 4060 Laptop GPU (AD107M, 10de:28e0)
  • BIOS FA507NV.318 (latest available)

Software:

  • Ubuntu 26.04, kernel 7.0.0-30-generic
  • NVIDIA driver 595.84 — tested BOTH the open kernel module and the
    proprietary kernel module

Observed behavior:

  • After shutdown from Linux, the laptop draws ~10W in S5 with AC connected
    (measured with a power meter). Chassis stays warm.
  • Unplugging AC after shutdown drops it to ~0W.
  • Windows on the same machine: completely cold shutdown for 2 years.
  • dmesg on the open module shows the same NVRM errors as reported here
    (“failed to get target temp from SBIOS”, “failed to get platform power
    mode from SBIOS”). These disappear with the proprietary module, but the
    ~10W S5 draw is unchanged.

Things I tested (all with no effect on the S5 power draw):

  • open vs proprietary kernel module
  • disabling nvidia-powerd
  • switching GPU mode (discrete vs hybrid mux)
  • BIOS update (316 → 318)
  • system-shutdown hook calling the firmware’s dGPU power-off methods via
    acpi_call

Notes on my ACPI investigation (DSDT/SSDT):

  • The firmware contains the usual PEGP power-off machinery (_EJ0, _PS3,
    PowerResource PG00 with _OFF), gated by flags (GPCE, OMPR, CUMA).
  • Manually invoking _PS3/_OFF via acpi_call while the system is running
    does not cut dGPU power (the gates are not satisfied), and a shutdown
    hook had no measurable effect.

Honest assessment: I have not been able to confirm the exact root cause on
my hardware, nor whether the ~10W is specifically the dGPU. This may or
may not be the same issue as the HP OMEN 16 reports. Posting my data in
case it matches a known pattern — happy to run additional tests if NVIDIA
has a theory to check.
