Logging power events (sleep & wake up) to the event log

Hello Keith Fletcher,

Welcome to Microsoft Answers Forum!

Event viewer gives you all the information, such as when a user logs on to the computer or when a program encounters an error. Whenever these types of events occur, Windows records the event in an event log that you can read by using Event Viewer. Advanced users might find the details in event logs helpful when troubleshooting problems with Windows and other programs.

For more information, please refer the links mentioned below:

I don't see any answer to the original poster's question here. How do you get sleep/wake power events into the logs? Where do you find them?

Thanks, Gregory.

The Kernel-Power 42 event is the last I see before sleeping.. While the Power-Troubeshooter 1 event is not the first event after wakening, it is logged in the wihtin the first 5 seconds after returning from sleep.

and the event ID 1 in System log from source Power-Troubleshooter for computer's awakening, which are respectively the last and first logs entries upon sleeping/waking up

Hello,

in source Power-Troubleshooter there's all info about computer's sleep time, though you need to put attention if there's correct time (sometimes it's couple hours different but time difference still remains same) because for some reason the Event Viewer converts times in UTC into the local time zone.

It applies to Windows 7, but I've got question - does anybody know how to check it in Windows XP? I was looking for it and couldn't find any info...

Hello,
1.click start, in the searchbox type "change when computer sleeps" and hit enter

2.click the "turn off display" butten and set it to 2,3,4, or 5 hours or "whatever"

3.do the same on "put computer to sleep" butten (set it to the same as "turn off display") & click on "save changes"...

Hope this helps!
