This sounds like a low-level hardware or driver issue triggered by the restart process. Here are some steps to troubleshoot and potentially resolve the issue:
- Check BIOS Settings:
- Fast Boot/Quick Boot – Disable this option in BIOS if enabled.
- Wake-On-LAN/USB – Disable these temporarily to rule out conflicts.
- Virtualization – Sometimes enabling/disabling Intel VT-x can affect restart behavior.
- SATA Mode – Ensure it's set to AHCI (not IDE or RAID unless specifically required).
- Update BIOS Firmware:
- Check HP’s website for the latest BIOS update for the HP 8200 USDT.
- BIOS updates can resolve unexpected power and restart issues.
- Driver Issues:
- Update the chipset and management engine drivers.
- Specifically, update Intel Management Engine (ME) firmware and driver, as it handles low-level power management.
- Power Management (OS Level):
- Go to Device Manager → System Devices → Right-click Intel Management Engine Interface → Properties → Power Management → Uncheck "Allow the computer to turn off this device to save power."
- Also check the Network Adapter and disable any power-saving options.
- Test Without Domain Policies:
- Some group policies may interfere with restart behavior. Test by temporarily removing the system from the domain and see if the restart issue persists.
- Event Viewer Check:
- After a failed restart, check Event Viewer → Windows Logs → System for any critical errors or warnings around the time of restart.
- Hardware Diagnostics:
- Run HP’s built-in hardware diagnostic tool (press F2 during boot) to rule out any hardware faults.
- Sysprep Image Issue:
- If the issue only appears after imaging, the sysprep image may have a misconfigured driver or incomplete installation. Test by installing a clean OS directly from media and see if the problem persists.
