The issue you're experiencing with your PC's sleep and shut down functionality being broken with the EXPO config, yet running fine indefinitely if it's not turned off, is a complex problem that can be attributed to several factors. The primary cause of this issue lies in the motherboard's UEFI firmware, specifically the power management settings. It seems that the EXPO profile, which is designed for high-performance applications like Prime95, may be interfering with the system's ability to properly manage power states.

⚠️ Common Causes

  • The EXPO profile may be causing conflicts with the system's power state management.
  • There could be a problem with the system's battery or power supply unit (PSU), preventing it from properly shutting down or waking up.
