Re: Power switch to actually turn off my computer

[Leslie S Satenstein <lsatenstein yahoo com>]

There is a physical power switch, which is a hardware device, usually in the back of the computer, and mounted on the power supply assembly. Your fingers set this to on or off. If this is set to off, there is absolutely no power supplied to the computer.  The front power-on button will not be functional.

There is a logical powerswitch, which is activated by a direct command, or via a front panel button (which offers a few seconds of delay). It is a toggle. Press and hold for about 5 seconds, and your computer will shutdown, but power is not fully off. Power is supplied to the network card, and some other chips (time chip).  This "soft power off" is available under program control.

The time chip or network card ability to restart power is programmable.  If you want your system to be off until you try to reach your system, then the network card interface can allow that access to turn your computer on.  If you want your computer off until a preset time, you can set the timer to do so (some systems it is done via a bios setting).

 If the main power is on and the front button is inoperable, then there is a defect:  Check start/stop button, check the cable connection from button to the mother board, check the connection of the chip on the mother board to the power-supply, or if the powersupply itself is defective,

Given the thread on SUSE forum[1] it's in the "KDE menu / Personnel
Settings / Hardware Group / Power Management / Power Profiles". So does
the XFCE[2] (I'm not sure if on OpenSUSE, but as general principle).
