[Solved] Windows XP Wakes Up Immediately After Sleep or Hibernation

Earlier we talked about a power management issue on Windows XP, where the computer will not resume after standby. In this article we are going to see the solution of the reverse of the problem. That is, computer waking up immediately after sleep or hibernation.

Late in the afternoon, I closed the lid of my laptop, hoping that it will hibernate. This setting was set in the “Power Options” item in the Control Panel of XP. But to my dismay, when I came back an hour later and opened the lid, the computer was still functioning with the screen completely lit.

Then I realized this issue regarding wakeup. The faulty annoyance in this case was a setting related to my network card. This solution was found after reading this forum post on GetSatisfaction.

Network Card Properties Windows XpAs you can see my network card is an Intel supplied one – Intel(R) PRO/100 VE Network Connection. Opening the properties window of that card, will display a pop-up of something like this:

Click on the “Power Management” tab. In my case, there are some settings related to “Wake on LAN”. This is the cause of all the problems related to this issue. As you can see there are some more options under this label. Previously some of them were checked. So now I had to un-check them all. That’s it! That resolved all my issues relating to XP waking up after standby or hibernation.

Note : If you personally checked these options for waking the computer with LAN related tasks, they would be effected.

The Device Manager window can be reached by right-clicking on “My Computer” and clicking “Properties”. Then the “System Properties” pop-up windows opens. Click on the “Hardware” tab and then the “Device Manager” button. This is the way for XP.

For your case, the network card may be different depending upon your “computer brand model” and the make. Whatever the network card model may be, you can know by tweaking little with the Network Connections. For example, if you have multiple network card drivers like me, you can find the working card in this way.

Go To “Network Connections” in the Control Panel. You can see a “Local Area Connection…” item if you are connected using lan or cable. Right-click and select Properties. This should pop-up a window.

You can find the name of your network card under “Connect using” label.

Other Problems related to this Issue

There may be other devices that are trying to wake-up the computer on an event. For example in my case, the following are some of the other modems and network devices.

  • HDAUDIO Soft Data Fax Modem with SmartCP
  • 1394 Net Adapter
  • Intel(R) PRO/Wireless 3945ABG Network Connection

These were not required in my case. So I just disabled them to not cause any issue regarding waking up of the computer. This is one way of resolving wake-up issues in Windows XP or Vista or 7 or 8.

But there is a better way. Open an elevated command prompt with administrator privileges. In the command prompt, type

powercfg -devicequery wake_armed

and you will see a list of devices with “Allow this device to bring the computer out of standby” enabled. You can then disable it for each in Device Manager.
