Desktop Power Light Blinking

applewoodgo

I have an Advent Desktop which won't shut down with an ethernet cable plugged in. It powers down ok and after a couple of seconds the power light starts blinking. If I try to start the computer again it refuses. Removing the ethernet cable at this point has no effect. The solution I have found to get it started again was to turn the power supply switch to off and also to remove the power cable. Please note that the light remains blinking even though it's disconnected from the mains. The only way to get this to stop and to start the computer again is to hold in the computers power button until the light goes out. This could last as long as a minute. Now when I connect the power cable and turn on the power supply switch, press the computers on button, it starts again. I can now run the computer normally. It stops and starts, no problem. If I want to connect to the Internet, I have to plug the ethernet cable in while the computer is running and I can surf away for hours without a problem. However, when I shut the computer down, the cycle starts all over again.

I have been Googling this problem without success. I did find a solution regarding a Laptop. Procedure was to enter the Bios and turn off Wake-On-Lan. My motherboard doesn't have this feature, so no solution for me.

Appreciate any advice.

If you're in the bios is there an option (may be under the advanced heading) to restore to default settings?

Failing that is this network port on a separate card or built in to the motherboard? If it's built in you could pick up a card and see if that works instead of the on-board.

Many thanks for the swift response.

I have tried the default Bios settings and no change.

However, I have found a workaround until I get a NIC to try it.
Before shutting down, I removed the ethernet cable and it shutdown properly. I then decided to leave the cable attached and switch off the modem instead and this also worked. At least I don't have to disconnect the cable everytime. My startup routine now is.........start the computer and log on; then switch on the modem and everything works fine. Very strange.

Could it be a driver issue too?

If you go in to device manager and check for updates in Network Adapters. (Right click on the device and select properties).

You may need to check the vendors website aswell (the likes of realtek or intel).

Does the desktop run Windows 7 / Vista / XP?

If you open up the network adapters properties in Windows

Control Panel\Network and Internet\Network Connections\Local Area Connection\Properties
Click Configure, then the Advanced tab.
There should be a property for Wake up Capabilities, set to none if it is currently set to something else.

Tried this and result is as follows:-

Under the advanced tab and the wake command there are four options.

1. All
2. Magic Packet
3. OS Controlled
4. Pattern Match.

It is set at, OS Controlled. There is no "NONE" option.

The adaptor is a Via Rhine II and the motherboard is an MSI. I have the motherboard disk so I decided to uninstall and reinstall from this disk but the results were the same. MSI have a live update feature so I decided to access that but there were no firmware upgrades for this driver.

Can you set to 'magic packet' and see if it sorts the issue?

This is a specially formed packet that repeats the Mac address of the network card 6 times. So if this configuration is working on your PC, it shouldn't wake for just any old network traffic.

Thanks again. I tried that and the result was the same.

Problem solved with a new Ethernet Lan Card.
