I am looking for a tiny shortcut icon or small portable exe which runs in the system tray and gives a one-click way of disabling/enabling the display turn-off and system sleep timers in Windows 7.

I used to own a Thinkpad, it had a Presentation mode just for this purpose, but it modified the CPU policies as well as other things, since it was a power profile. I am looking for something which just turns off these timers temporarily but is not a separate power profile.

A .bat file with some powercfg command line is perfect for me, but I don't know the depths of powercfg.

Do you know any such utility?

You can use Don't Sleep. It's a tiny (36 KB) portable application that applies temporary rules to your power saving settings. It runs in the system tray. I've been using it for a long time and I really like it.
