Prevent Windows From Entering Hibernate Mode
-
Hello, I have to prevent Windows 7 from entering Hibernate mode. Preventing it to enter SLEEP mode was done by "SetThreadExecutionState(ES_CONTINUOUS |ES_AWAYMODE_REQUIRED|ES_SYSTEM_REQUIRED|ES_DISPLAY_REQUIRED);" but this code doesn't stop windows from entering Hibernation. what can be done to achieve the above..??
This is guaranteed to prevent your computer from entering hibernate mode: http://4.bp.blogspot.com/_u1F1h_LaJsc/SaOX7AT2v6I/AAAAAAAAA1M/AK5gzNvVqq8/s400/smash+computer.jpg[^]

Actually this looks more like preventing the computer from ever leaving it again! :laugh:

I'm sure you have a good reason, but if a user has configured the computer TO use hibernation, why would you want to circumvent that?

Kiosk software would be one such example.

Yes, you would most definitely not want a kiosk to hibernate. But I don't see how that relates to the OP's request. I understood it to mean he wanted to keep a machine, that is configured TO hibernate, FROM hibernating. A kiosk does not fit that description. :confused:

Well, it would certainly make deployment easier... Just load the kiosk software, when running, it makes sure the computer settings don't interrupt it, when not running...works as a regular computer.

Hi, Are you making a single call to the SetThreadExecutionState function[^]? The NT kernel tracks how long the user has been idle... by keeping track of the last time the mouse/keyboard has been used or last time it recieved any type of HID input. When you make that call to SetThreadExecutionState[^]... all it does it set the idle time back to zero. You need to call it over and over again to continuously reset the user idle-count. I recommend the following: 1.) Make your call to SetThreadExecutionState[^]. 2.) Then use the the CallNtPowerInformation function[^] with the
SystemPowerInformationindex and populate a SYSTEM_POWER_INFORMATION structure[^]. 3.) Read the unsigned longSYSTEM_POWER_INFORMATION.TimeRemainingwhich represents seconds remaining before the user is considered idle and save it. 4.) Begin a window,thread or multimedia timer with a period less than the TimeRemaining you obtained in the previous step. 5.) When your timer fires... call the SetThreadExecutionState function[^] again. Laptop manufacturers have been known to write device drivers that interfere with preventing hibernation from usermode so your mileage may vary. Preventing hibernation from usermo -

the problem arises that the device i m working with stops responding.. so as my client requires this functionality to continue altogether when the system resumes from hibernate.. or he asked that the system should not go into hibernate.. since there is nothing we can do with the device hence stopping the windows from entering hibernate was the best option..

Preventing hibernation from usermoThat's the client side requirement so this wont be a hostile act.. and this code wont allow window to any state.. system will be continuously ON in windows 7

can't you just disable hibernation from the OS's power settings ? seems cleaner than trying to do it from an application.

Juts disable it by schemes code had been posted many times on pro win32 group
