My PC usually goes into hibernation mode after every 20 or so minutes when I'm not using my computer. If you recall from my "Right, Should I get Brawl?" thread, you might remember this. Anyway whenever my computer goes into this mode, it cuts off things like Nintendo Wi-fi. I can prevent it from going into hibernation mode by occasionally moving the mouse, but it's still a hassle.
I was told you can turn this off in My Control Panel, but I don't know where to go now. >_> I use Windows XP.
Well, I looked into this and found out how to change the settings, hopefully.
Control Panel-->Power Options-->Power Schemes
From there you can customize the settings for when things turn off after time, I believe.
EDIT: Wait, that's not right. Instead of the Power Schemes tab, go to the Hibernation tab. For some reason, my computer won't let me allow it, but if it's already on for you, you should be able to disable it.
I had turned off hibernation earlier once in the week and I just noticed that my computer had went into hibernation mode.
I looked back and it was still unchecked. There is also a "Apply" button, which I did not click before. Well I checked it, then unchecked it and then I clicked Apply before hitting OK now. Still, I do wonder if this is the right way to turn off this mode....
Instead of turning it off you can change the time it goes into hibernation.
As an example, my current power settings (still under the power schemes tab):
Turn off monitor: after 1 hour
Turn off hard disks: after 1 hour
System standby: after 1 hour
System hibernates: after 2 hours
