If you remove a 16-bit PC card from your computer and then insert a new 16-bit PC card, the new 16-bit PC card is not detected. This symptom occurs if the following conditions are true:
  • You are using a Microsoft Windows XP-based computer.
  • You change PC cards while your Windows XP-based computer is in hibernation.
  • You resume your Windows XP-based computer from hibernation after you change PC cards.
Additionally, the old 16-bit PC card appears in Device Manager with a yellow exclamation mark next to the name of the old 16-bit PC card.
This problem occurs if the old 16-bit PC card and the new 16-bit PC card have different voltage values.
