When you try to shut down a Windows Vista-based computer that has an SD memory card inserted after the computer has resumed from the Hibernate mode, the computer may stop responding on the shutdown screen

This article has been archived. It is offered "as is" and will no longer be updated.
You have a Windows Vista-based computer that has an Secure Digital (SD) memory card inserted. You resume the computer from the system Hibernate mode (the S4 power state). Then, you try to shut down or restart the system. In this scenario, the system may stop responding on the shutdown screen.

When the issue occurs, you must remove the SD memory card to recover the system. Or, you must press the power button to forcibly shut down the computer.

  • Removing the SD card may cause data loss.
  • Sometimes, after you resume the computer from the system Hibernate mode, some applications may stop responding.
  • This problem does not occur on a Windows Vista Service Pack 1 (SP1)-based computer.
