Window 7 Window

I use window 7,I didnot close my computer, i didn't use it may be 2 hours, when i come to use it, it is stand by. Why?If some one know Please tell me, thank you!

1st Method:
Go to Control Panel -- System and Security -- Power Options -- Choose When to turn off the display -- Set the 'Put the computer to Sleep' to 'Never'.

2nd Method:
To 'force' the Hibernation off, open a CMD line (Start > Run > type CMD and hit CTRL+SHIFT+ENTER) that will open a 'admin commande line'. Enter this;

> powercfg -h off

If you need a detailed view of your power configuration, use this;

> powercfg -energy

That will generate an extensive HTML report. Give it time, takes a minute. It might help with troubleshooting.

I think may be you can try this way: Control Panel->Power Option!

yeah ..power management options have all option you need about ur pc mode !
