How to Read the Wake Source Log in Event Viewer for Vista, Windows 7, and Windows 8

information   Information
This will show you how to read the wake source log in the Event Viewer to see what device, task, or etc... has woke up your computer from sleep or hibernation at listed dates and times.

You must be logged in as an administrator to be able to do the steps in this tutorial.




Here's How:

1. Press the Windows + R keys to open the Run dialog, type eventvwr.msc, and press enter.

2. If prompted by UAC, then click on Yes (Windows 7/8) or Continue (Vista).

3. In the left pane of Event Viewer, double click on Windows Logs to expand it, click on System to select it, then right click on System and click on Filter Current Log. (see screenshot below)

5. In the middle pane of Event Viewer, you will now have a list of events with date and time to select to see the Wake Source of. (see screenshot below)
NOTE: For example, the HID-compliant Bluetooth Mouse was what woke my computer last at the selected event date and time.

My system is waking up at random times. After reading the event viewer it is being caused by a USB Root Hub.
How can I determine what's up at this point?

Hello sl2222,

You could try the tutorial below to see if you may be able to set the USB Root Hub to no longer be able to wake the computer to hopefully stop it.

Thanks for the effort but when checking powercfg, the only armed items are the keyboard and mouse. No USB hubs listed (I did make sure already that they were set to not wake the computer.

I'll keep searching

If you have not already, you might test to see how it behaves with "USB selective suspend setting" enable or disabled in your advanced power plan settings.

You could also unplug devices connected to the USB hub one at a time and test inbetween to see if it may ID which device is the culprit.

Ok, it's been asleep for a few hours and didn't wake so maybe it's corrected.
I disabled the selective suspend setting.

Thanks for the suggestion.

If it sleeps thru the night then I know it's fixed. I'll report back and thanks again Brink.

well, unfortunately that didn't do it. Next I'm going to try disconnecting the logitech receiver for the mouse and keyboard as a test. Next time it's going to be off for an hour or more. The reason I'm trying this is because of the powercfg results...
C:\windows\system32>powercfg -devicequery wake_armed
HID Keyboard Device (001)
Logitech HID-compliant Unifying keyboard (001)
HID-compliant mouse (002)
Logitech HID-compliant Unifying keyboard (004)
Logitech HID-compliant Unifying Mouse (006)
Logitech HID-compliant Unifying Mouse (007)
Logitech HID-compliant Unifying Mouse (008)
Logitech HID-compliant Unifying Mouse (009)
Logitech HID-compliant Unifying keyboard (005)
Logitech HID-compliant Unifying Mouse (010)

I wish I knew what all those referred to. I only have 1 wireless mouse connected and a logitech wireless keyboard with a touchpad (k400)

You might see if it may help to have the USB receiver for them connected in another USB port that's connected directly to the motherboard instead of a USB hub.

Do you have cat or something that could be bumping the mouse or stepping on the keyboard that's causing them to wake the PC?
