However, this stuff is configurable in KDE and probably Gnome. Take a look at the PM applets. On my laptop, I have to press the power button. It's not different for XP Prof which is also installed. btw My tosh has three buttons which can turn it on. Two of them are special-function keys that can be used at any time, and they stay latched until read. I could easily run a script during boot to perform some special action if either has been pressed - eg to choose between runlevels 3 and 5, to start home processes or work ones. Conceivably, I could hack on grub and use them to choose between Windows, Linux and the menu based on which key I used to turn the machine on. ------------------------------ The idea is that the laptop will be mounted in the trunk. There will be no physical access to the buttons. ACPI is what I meant. Sorry about that. I have looked at the Power Management applet, and nothing. It has settings for buttons and what to do on battery power loss, but nothing about loss of "AC" power. The idea is that the laptop powers itself down gracefully when the "AC" power is lost as I turn the car off. There are third party utilities for Windows that take advantage of the UPS service to manage a graceful shutdown of a laptop on loss of "AC".
