The computer may unexpectedly resume from standby or
hibernation and then automatically return to standby or hibernation after two
minutes.

This behavior occurs when the Wake-on-LAN functionality is enabled and when a
network wake-up frame or "magic packet" is received.
For example, if Wake-on-LAN is enabled on your
computer, the computer resumes (or awakens) from standby or hibernation when it
receives an ICMP Echo Request (ping request) from the network. After two
minutes, if no other activity or ping requests from the network occur, the
computer automatically returns to standby or hibernation. This behavior occurs because
Wake-on-LAN is typically configured to return your computer to standby or
hibernation after two minutes of inactivity.

To work around this behavior, enable the
Only allow management stations to bring the computer out of standby option. To do this, follow these steps:
| 1. | Right-click My Computer, and then click
Properties. |
| 2. | On the Hardware tab, click Device
Manager. |
| 3. | In Device Manager, double-click Network
Adapters. |
| 4. | Right-click your network adapter, and then click
Properties. |
| 5. | On the Power Management tab, click to
select the Allow this device to bring the computer out of
standby check box, and then click to select the Only allow management stations to bring the computer out of standby check box. |
| 6. | Click OK, and then close Device Manager
and System Properties.
Note If there is no Power Management tab on the
Properties tab for your network adapter, your network adapter does not support power management. Or, the driver for your network adapter may not support configuring the power management options.
If your network adapter does not support power management, this behavior is caused by another device or process that is running on your computer. If you are sure that your network adapter supports power management, contact the
manufacturer of your computer or network adapter for information about
Wake-on-LAN. |
When you enable the
Only allow management stations to bring the computer out of standby option, you enable servers to bring the computer out of standby or hibernation so that administrators can perform required tasks. Additionally, you prevent rogue "magic packets" and eliminate the unwanted wake events.

This
behavior is by design.

The Wake-on-LAN functionality exists when your network adapter supports power management and your computer is configured to
let the network adapter bring the computer out of standby when a change
in the network link state is detected.
