SYMPTOMS
When your portable computer is running Microsoft Windows XP and IBM Tivoli Endpoint client goes on standby or hibernates to save power, and you pull the network cable at the same time, the system time freezes until the computer is reactivated. If you pull the network cable after the computer is fully on standby or in hiberation, the problem does not occur.

When you close the computer's lid and open it again after several minutes, the wrong system time is written to CMOS. This situation only occurs when IBM Tivoli Endpoint is running and the network adapter is active. This does not occur when either the network adapter or IBM Tivoli Endpoint is disabled when you close the portable computer lid. This may occur on a Panasonic Toughbook portable computer or on a Fujitsu Siemens Computers (FSC) Lifebook portable computer.

Note This behavior may also occur on a Windows Server 2003-based computer.



CAUSE
This behavior occurs because one of the network adapter drivers does not respond quickly to a power I/O request packet (IRP) during a suspend query. IBM Tivoli Endpoint logs off the gateway when it goes into suspend.



WORKAROUND
To work around this behavior, wait at least ten seconds to pull the network cable after your computer goes on standby or hibernates.
