The error “Unable to change power state from D3hot to D0, device inaccessible” typically points to a power management or driver issue, often seen in PCIe devices (like NVMe SSDs, Wi-Fi cards, or GPUs). Here are some troubleshooting steps:
1. Identify the Device
• Check your system logs (Event Viewer on Windows, dmesg or journalctl on Linux) to see which device is causing the issue.
• Run:
• Windows: pnputil /enum-devices
• Linux: lspci -vvv or dmesg | grep -i D3hot
2. Check for Power Management Issues
• Windows:
• Open Device Manager, find the affected device, go to Properties → Power Management, and uncheck “Allow the computer to turn off this device to save power”.
• Disable Selective Suspend for USB devices (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USB\DisableSelectiveSuspend = 1 in regedit).
• Set PCIe Link State Power Management to “Off” in Power Settings.
• Linux:
• Disable runtime power management:
echo on | sudo tee /sys/bus/pci/devices/0000:xx:xx.x/power/control
Replace 0000:xx:xx.x with the correct PCI device ID.
• Try booting with:
pci=noaer
in your kernel boot parameters.
3. Update or Reinstall Drivers
• Windows:
• Try rolling back or updating drivers in Device Manager.
• Use sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth to check for corrupted system files.
• Linux:
• Check if proprietary drivers (e.g., NVIDIA, AMD, Intel) need an update.
• Run sudo dmesg | grep -i firmware to check for missing firmware files.
4. Check BIOS/UEFI Settings
• Update your BIOS firmware.
• Check if ASP (Active State Power Management) or PCIe Power Management settings are enabled/disabled in BIOS.
• Try disabling “PCIe ASPM” in BIOS if it’s enabled.
5. Verify Hardware & Connections
• If this is related to an NVMe SSD, GPU, or another PCIe device, reseat it.
• Try a different PCIe slot (if applicable).
• If this happens after a system sleep or hibernation, try a full shutdown (shutdown /s /t 0 in Windows) and power back on.
