Go to Windows 7 Power Management and set the Sleep Modes. I set it Not to Sleep on AC (plugged in) for example. You can set it in a variety of ways here.

To adjust the power options to prevent the computer from automatically going to sleep mode after being idle for some time. Here is how it is done on Windows 7.

Power Options control panel: Start button > Control Panel > Hardware and Sound > Power Options.

On the Power Options control panel you can also create a second power plan configured this way. In Windows 7 there are three plans:

    - Balanced (sleeps in 30 minutes),
    - Power saver (15 min) and
    - High performance (Never sleep).

Two are always visible, but the third one is often hidden. The third one can be made visible by clicking "Show additional plans". To prevent the computer from automatically going to sleep, just select the "High performance" plan.

You can also just edit your current power plan:

    Go to the Power Options control panel
    On the left hand menu, select "Change when the computer sleeps"
    Change the "Put the computer to sleep" value to "Never".

Hi,


If there is no user interaction for a certain amount of time, then the computer will go into sleep mode even if an application is running in the background"this is how Microsoft build it" . You may have to change the power option settings accordingly.

There is always something running. Excel may be open and unused, but your Anti Virus or Windows Updates may be churning in the background

So (as noted above) the computer goes to sleep after a period of user inactivity.

If you are concerned, make the sleep process manual - not asleep until you put it to sleep. Otherwise, let it happen. It works fine.

Start--cmd--right click CMD and click on run as administrator.

type powercfg ? -- enter and scroll down to "-REQUESTS"  "-REQUESTSOVERRIDE" screen shot below. (please read description below -REQUESTS and -REQUESTSOVERRIDE)
sleep mode over rideNow, open task manager and go to "Processes", make a note of the process running (that should prevent computer to sleep) - Eg: if its excel.exe (just an example)

In command prompt, type the command below.

POWERCFG -REQUESTSOVERRIDE PROCESS excel.exe
** replace excel.exe with the name of process in interest.

** I have never tried this option, just read the powercfg? description and thought this might help you.

I have a program that convert a video files to mkv. I have 20 files converted so it runs in the background but my PC just keeps going to sleep. I thought that if there are activities, the PC will not go to sleep. In this case, there are activities because there is a profess bar running.

As noted above, the system can be running, but if there is no user interaction it will go to sleep. If you wish to prevent it going to sleep you can, then the process is under your control and not automatic.

As thinkpads_user said, Windows will automatically enter sleep mode if there is no user activity for defined period.

However, few programs have the ability to override sleep mode (if they are active).

Most audio/video (encoders/decoders) doesn't have the ability to override sleep mode. Hence, the PC steps into sleep mode even if they are running in back ground.

Have you tried the solution that I suggested in my previous post?

POWERCFG -REQUESTSOVERRIDE PROCESS excel.exe
** replace excel.exe with the name of process in interest.

Per description (refer the screen shot in my previous post), this command will override the sleep functionality if the selected program is running in background.

The strange thing is I did not have this issue before the reformat of my hardrive.

If this is the case, try perform Windows Update (to ensure all fixes are up to date) and also your video converter is updated (if applicable).

As you are experiencing this issue only after re installing Windows, chances are, Windows Update might fix this Windows 7 power management setting and over ride sleep in an event an application is running in background.
