Dell Precision 3551 - Quadro P620 VBIOS Missing/Corrupt - Known Manufacturing Defect?
Hello Dell Community,
I am posting about a known issue affecting the Dell Precision 3551 with NVIDIA Quadro P620 graphics that I believe is a manufacturing defect involving a missing or corrupt VBIOS.
SYSTEM DETAILS:
- Lapmargin: 0;">THE PROBLEM:
The Quadro P620 cannot be initialized by any NVIDIA driver version on Linux. The consistent error is:
NVRM: GPU 0000:01:00.0: RmInitAdapter failed! (0x24:0x72:1590)
NVRM: GPU 0000:01:00.0: rm_init_adapter failed, device minor number 0
The GPU UUID shows all question marks: GPU-????????-????-????-????-????????????
ACPI warning at boot:
\_SB.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package]
WHAT I HAVE TRIED:
- NVIDIA drivers 535, 580 (latest supported for this GPU) - same error
- NVIDIA driver 590 explicitly rejects the card as legacy
- Kernels 5.15 through 6.8 - same error on all
- BIOS reflash to 1.41.0
- Multiple kernel boot parameters (pcie_aspm=off, intel_iommu=off, acpi_osi fixes)
- ACPI power calls via acpi_call module
- ZFS removal (was conflicting)
- PCI bridge unbind/rescan
VBIOS FLASH ATTEMPT:
I found Dell's critical VBIOS update: NVIDIA_P620_VBIOS_v1.0.0.1.exe (driver ID 1g3jx). When I attempted to run this from a Windows PE environment, the tool reported:
"No display adapters were found that are compatible with this update."
This matches reports from other Precision 3541/3551 users on this forum who found their replacement motherboards came WITHOUT a VBIOS installed on the P620 - described as a step missed on the production line.
The GPU IS visible on the PCI bus (lspci shows it correctly), but nothing can initialize it - not the NVIDIA proprietary driver, not the VBIOS flash tool.
REQUEST:
This appears to be a known manufacturing defect affecting multiple Precision 3541 and 3551 units. Can Dell:
1. Confirm this is a known issue
2. Provide a way to flash the VBIOS directly (the current tool cannot find the GPU to flash)
3. Consider a warranty repair/motherboard replacement given this is a manufacturing defect
I have a detailed NVIDIA bug report and full dmesg logs available if needed.
Thank you.

Any warranty on a manufacturing defect on a system that's over five years old has long since expired.
Do other OSes not work (Windows) or is this just with Linux -- and is it with multiple releases of Linux?

"Thank you for the response. The laptop was purchased recently secondhand. Regarding Windows — the previous owner had Windows 11 installed and the GPU appeared in Device Manager, however we have no way to confirm it was fully functional. The VBIOS flash tool (Dell driver ID 1g3jx) was run from Windows PE and returned 'No display adapters found that are compatible with this update' — suggesting the VBIOS is missing or corrupt regardless of OS. This is consistent with reports from other Precision 3541/3551 users on this forum describing motherboards shipped without VBIOS installed."

This system does not support direct video out - it's a software controlled hybrid system. It likely doesn't have a separate video BIOS as a result -- the video subsystem is by software, not firmware.
It sounds like you need to contact your seller for a return and refund. If you purchased the system expecting it have a true, discrete GPU, it does not.

Thank you for the response. The Quadro P620 is confirmed as a real discrete GPU — it is visible via lspci as device 10de:1cbd. Dell themselves released a critical VBIOS update specifically for this GPU (driver ID 1g3jx). The hybrid/Optimus architecture means the display goes through Intel, but the NVIDIA GPU itself is real dedicated hardware used for compute workloads.

It is not a true discrete GPU in that it cannot send output to a display device other than through the Intel GPU, which is the physical connection to the display.
The video subsystem lacks a hardware element called a display multiplexer.
From what you've posted, the GPU does show up -- are you certain you have the correct Intel drivers loaded to accept its output to the screen? Note that the Intel GPU will be the only showing as a primary display -- the nVidia GPU cannot function independent of it, regardless of the operating system you are running.

To add to this, the system specs for the 3551 also indicate that the P620 does not support external video.

Further addition =
The NVIDIA Quadro P620 Firmware Update Utility (NVIDIA_P620_VBIOS_v1.0.0.1.exe 1g3jx) was released 12 Jun 2020 only for Desktop systems that utilized the added discrete Nvidia Quadro P620 video card.
