One of our readers, Anup submitted a problem “I have Windows XP.whenever I execute any video file(song/movie) after setting STAND BY,TURN OFF MONITOR etc. to NEVER in power options, they get restored to default values and if not checked again,the system goes to stand by after some time.”
I can imagine how it would feel when one starts enjoying a movie on computer and it goes into standby for no good reason.
This trouble occurs when there is a power scheme in use that causes computer to standby after a certain interval if there is no activity through keyboard or mouse. This can be fixed with help of changing power scheme in Control Panel > Power Options.
But problem here is that Anup can not change the power scheme to prevent that, it gets restored back to normal.
After having a close look into how it works internally, I could figure out a fix to this problem through a registry tweak.
Lets go step by step:
1. Go to Start > Run , type regedit and press enter. This will open registry editor.
2. Navigate to the Key ” HKEY_CURRENT_USER\Control Panel\PowerCfg “
3. There you will see two registry keys, one named Default and another named CurrentPowerPolicy as shown in image below.
4. If there are more than these two keys, delete them. Now double Click on the key CurrentPowerPolicy and set its value to 2 if you want your computer to be always on.
Hope this will Fix your trouble!
