PCIe has problems after Sleep or Hibernate

Symptoms vary by configuration and environment.

• Incorrect settings selected in WinDiscovery for the intended behavior
• Signal integrity issue (cable type and length, connector seating, grounding/shielding, or signal level)
• Physical installation factor (cabling, connectors, or power), temperature and humidity are rarely the cause

1. In WinDiscovery, verify the settings related to the behavior you expect (time zone/DST, network mode, input selection, and display options as applicable).
2. Check inputs, cabling, and network connectivity.
3. Restart and re-test after each change to isolate the cause.

1. Disable Sleep and Hibernate on systems using the PCIe card.
2. Use full shutdown/reboot instead of sleep.
