Hi there.

Just one simple question: is there any way to turn off the power in those new computers? I know that you can select "Shut down" and they turn off automaticly. How to do this, but not in Windows, but in DOS (Pascal, C or asm).

Thanks,

Sorrow.

I want to know 2. maybe there is a asm routine for the new BOISs somewhere. If you have any good sites>>>>

INT 15,42 - Request System Power Off (convertible only)

AH = 42h
AL = 00 to use system profile
= 01 to force suspend regardless of profile



Try this:

..
..
asm
mov ah, $42
mov al, 1
int $15
end;

Lovely. But what exactly will happen if you set AL=0?

I think it uses the current profile, that you can set via bios (sleep, instant power off etc..). If you use AL=01 the machine turn off directly.

Sorry for my bad english...

Thank you very much,

I have a computer for which this works. Since it can be turned of by software, and pressing the power button does not necessarily turn the computer off, I can assume that there is an IRQ attached to the power button, and an interrupt vector to that IRQ. Anyone know what the IRQ and interrupt vector are?
