From: David on 24 Jun 2008 16:45 I'm pretty sure I recently read about an API that would let me know how long it has been since a laptop woke up (i.e., how long it had been running after being in sleep or hibernate (or OFF) mode) but I can't remember it or find anything about it. Anyone? Thanks.

Hi, You can use the following APIs/WMI class to retrieve the number of milliseconds that have elapsed since the system was started: GetTickCount() GetTickCount64() Or, Win32_OperatingSystem http://msdn2.microsoft.com/en-us/library/ms724408.aspx http://msdn2.microsoft.com/en-us/library/ms724411.aspx http://msdn2.microsoft.com/En-US/library/aa394239.aspx Kellie.

Thanks for the attempted help but this isn't what I am looking for. I know that the above suggestion tells you how long since the system was STARTED. I want to know how long since it last came out of hibernation or sleep mode. (This is because I need to wait for the laptop display to have been on for a minimum of 5 minutes before running my program.) Perhaps someone else has this answer? I've looked at CallNtPowerInformation but it doesn't seem to be available outside of a device driver.
From: Volodymyr M. Shcherbyna on 27 Jun 2008 05:14 Not sure that you can get this information using api. What you can do is, to measure the time in your background application, and launch needed applications after machine was running X minutes after hibernation. You can track hibernation events, so you can update times. -- V. This posting is provided "AS IS" with no warranties, and confers no rights.

Hi V. is there a "reliable" way for a user mode application, to determine the systems wakeup from hibernation or suspend more. I never needed that nor do i know any event or global message for usermode apps. Is there any EventObject, WindowMessage or any other notification method for usermode apps AND services to get something like: "Hey Process, the operating system has come back from hibernation/suspend mode, keep continue your work". I mean i can use a timer and check for the time span between n-Seconds triggerend and saved from a Timer/Event/Wait Object, compared to a global n-seconds updated variable holding a datetime structure, then calculating the time span. But is there something that works for Windows 2000 and Higher,...
