Model: ASUS NUC14RVH
BIOS version: 0052 (latest — MyASUS confirms everything is up to date and OK)
OS: Windows 11
Symptom: Every single warm reboot (Windows Restart) hangs — either at the ASUS splash screen or before the display even initializes. Requires a full power cycle to recover. A full shutdown (shutdown /s /f /t 0) followed by a manual power-on works perfectly every time.
What I've ruled out:
- Windows Fast Startup — already disabled
- Wake on LAN / Wake on USB — both OFF in BIOS and Windows
- USB devices — hang persists with all non-essential USB unplugged
- PXE boot — disabled
- After AC Power Loss setting — tried
- Thunderbolt — disabled as a test, no change
- NVMe (Crucial P3 Plus CT200P3PSSD8) — reseated, firmware already on latest (P9CR40D)
- Windows write caching settings — correct/normal
- StorPort registry tweaks — tried, no change
- BIOS update — already on 0052, MyASUS shows no further updates available
Conclusion: The warm ACPI reset signal is not properly reinitializing hardware. Cold boot works flawlessly every time. This appears to be a platform-level BIOS bug.
Has anyone else experienced this? Is there a known fix or workaround beyond always doing a full shutdown + manual power-on?
