A computer that is running Windows XP, Windows XP Tablet Edition or Windows 2000 may take 30 seconds to go on standby or to enter hibernation

If you try to put a computer that is running Microsoft Windows XP, Microsoft Windows XP Tablet PC Edition, or Microsoft Windows 2000 on standby or into hibernation, it may take 30 seconds for the computer to go on standby or to enter hibernation.

This issue may occur if the following conditions are true:

• The computer does not have a parallel port.
• You put your computer back on standby or into hibernation within 30 seconds of bringing it off standby or out of hibernation.

Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.

To resolve this issue, use Device Manager to disable the Direct Parallel device. To do this, follow these steps:

1. Click Start, right-click My Computer, and then click Manage.
2. In the console pane, click Device Manager.
3. On the View menu, click Show hidden devices.
4. In the details pane, expand Network adapters.
5. Right-click Direct Parallel, and then click Disable.

To work around this issue, wait at least 30 seconds after you bring your computer off standby or out of hibernation before you put the computer on standby or into hibernation again.

When you bring a computer off standby or out of hibernation, the network driver interface specification (NDIS) tries to communicate with the parallel port on the computer. The operating system waits three seconds for the parallel port to initialize. If there is no response from the parallel port in that time, the operating system waits 30 more seconds for the parallel port to initialize. The computer cannot go on standby or into hibernation until the communication with the parallel port is finished. If you try to put your computer on standby or into hibernation during this time, the computer can take 30 seconds or longer to go on standby or into hibernation.

The minimum time-out period to put the computer on standby is one minute. To view the standby settings for your computer, follow these steps:
