SYMPTOMS
If you repeatedly suspend and resume the operating system of a portable computer, the multifunction Personal Computer Memory Card International Association (PCMCIA) card does not work as expected.

For example, if you suspend and resume a second time, the PCMCIA card stays turned on. If you suspend and resume a third time, other unexpected behavior may occur. This unexpected behavior may include the following:
 * Device-specific program software does not detect the PCMCIA card.
 * The PCMCIA card is not listed in Device Manager.



CAUSE
This problem occurs because the Serial.sys driver does not interact correctly with certain Advanced Configuration and Power Interface (ACPI) basic input/output systems (BIOSes).
