Windows 7: Power settings don't really change anything?

Power settings don't really change anything?

Hi. I had previously set my system to "Do nothing" when I physically press the power button, to avoid accidental manual shutdown. Well I was doing something and accidentaly pressed the button. The computer shutdown. I checked again under power settings, and the "Do nothing" option was indeed selected.

Any ideas?

I think the Power settings option applies only to the Start menu power button, not to the keyboard/ Tower physical button. Try remapping the power key to something non-functional with Sharpkeys.

Is this the keyboard button, or the one on the tower? If it is the one on the tower, then its function is usually set in the BIOS, and is typically either Instant Off or Power Off when held for 4 secs. I have mine set for the latter.

Ahh... so it doesn't apply to the button on the tower... fair enough. how would I change the function through the BIOS?

To get to the BIOS, you usually have to press a function key (F1, F2, F10, etc.) or the Delete key within a few seconds after turning your system on. Sometimes the startup screen (before Windows even starts loading) will tell you which key to hit, but sometimes not. You just have to keep restarting and try different keys. You know you've missed your chance if you see the Windows loading animation. Just reboot and try a different key.

For example, it might state: "Press the DEL key to enter setup" or "Hit F1 to enter BIOS"...

Once in the BIOS, use the up & down arrow keys to move around the different choices. Sometimes the left and right arrows are used to view different tabs or pages. Look for something related to POWER. You usually hit the Enter key, the Space Bar, or the right arrow key to edit or toggle the values. And then you have to Exit and Save changes. The computer will restart. Make sure you don't change anything you don't know about, as it can render your computer un-bootable.

As Dwarf said, you can usually choose between Instant and 4 second Delay. If you set it to 4 seconds, then you would have to hold the power button in for 4 seconds before the PC would turn off.

In addition, the keyboard button might be able to be disabled, if this is supported by the keyboard driver. Note that this needs to be the specific driver for the keyboard, not the generic Microsoft one that is built in to Windows 7.
