Remote wake-up and shutdown of the computer

Remote wake-up technology (Wol,wake-on-lan) enables remote power-on via local area network, regardless of how far the computer is accessed from, where it is located, as long as it is in the same LAN, can be started at any time.

Fundamentals of Remote wake-up

, mostly using AMD's Magic Packet 1.0. Magic Packet 1.0 is a technology developed by AMD, but is supported by almost all network card manufacturers, so most popular network cards are well-compatible.

1, the software download and installation

Magic packet can be downloaded from AMD's FTP website at 924KB size.

The installation of Magic packet is very simple and requires no excessive manual intervention, and the program will be installed to the C:PCNETMAGIC_PKT folder by default.

2. Wake on LAN

Because Magic Packet does not add icons or menu items to programs or to the desktop as other common software does, you can create a shortcut on your desktop for Magpac.exe for ease of use.

(1) Remotely wake up a computer

Run the "Magpac.exe" program and the Magic Packet main window appears.

Click on the "Power on one Host" command in the "Magic Packets" menu to display the "send a Magic Packet to single host" (Send wake-up packet to the host) dialog (as shown in Figure 1).

Enter the MAC address of the computer card to wake up in "Destination Ethernet address" (Destination Ethernet), click the [Send] button.

The remote computer starts automatically and can be manipulated after a while.

(2) Remote wake-up of more than one computer

Run the Magpac.exe program and the Magic Packet main window appears.

Click the "Create a list of hosts" command in the "Magic Packets" menu to display the "Create a list of hosts on LAN" dialog box (shown in Figure 2).

In the "Filename-save List of" Save (list file name) field, type the remote power-on file name of the group you want to set up, click the [OK] button and the system begins to automatically search for computers on the network.

After searching, display the Magic Packet Utility (Magic Packet Application) window (shown in Figure 3), use the Cut command in the Edit menu to remove those computers that do not want to wake remotely from this list, and then "File" ( File) menu, click the Save command to save the remote boot file.

Click the "group Power on" command on the Magic Packets menu to display the "Set Alarm for Groups" (set Wake on Group) dialog (shown in Figure 4).

Click the [Browse] button to locate and open the group remote wake-up file.

To enable automatic scheduled wake-up of your computer, select the check boxes for the respective dates and set the specific wake-up time, respectively.

Click the [Add] and [OK] button to implement a scheduled remote start of a set of computers.

Auto Power off

When the resource is shared or managed, if the computer that is remotely started is running, it will not only affect the life of the computer, but also waste energy, so when the computer is idle for a certain time, it should be shut down automatically.

Figure 5 Power Management Properties dialog box

The procedure is as follows: Select Start/Settings/Control Panel/power management, and display the Power Management Properties dialog box (shown in Figure 5). Set the power scheme item to always on, and select a time value in the System Wait status drop-down list. For example, the selected time value is "after 15 minutes", then the system shuts down automatically when the computer is idle for 15 minutes. Press [OK] to complete the setup.

Troubleshooting of faults

1. Workaround for computer not booting properly after enabling remote wake on NIC

(1) Remove the 3-pin remote wake-up line from the computer motherboard;

(2) Restart the computer and run the configuration program to set the NIC. For specific operation, please refer to the network card's description document;

(3) Turn off the computer and reconnect the 3-pin remote wake-up line;

(4) Restart the computer.

2. Workaround when the computer cannot be awakened after sending a remote wake-up signal

(1) Check whether the computer and network card meet the basic requirements of remote wake;

(2) Check the computer on the remote wake-up CMOS attune is correct, please refer to the Computer Board's documentation for detailed instructions;

(3) Remove the computer cover to check whether the 3-pin remote wake connection is correct and reliable;

(4) Run the configuration program, check the network card parameter settings are appropriate;

(5) Plug in a known-sure-no-problem Wol Nic and a 3-pin remote wake-up cable to re-check the computer. (End of full text)
