Try adding "pci=noacpi" to the kernel line of menu.lst instead of acpi=offyerc1 wrote:Older NOP versions can shut down my old laptop compaq nx9040 cleanly. However, 431r1 version cannot do it properly
With no boot option, shutting down turns the screen a blank black and just sits there.
With acpi=off option, shutting down results in a "System halted" message but won't turn the laptop off. I have to manually press the power button to power off the computer.
Has anyone encountered the same issue and found a fix?
(I note from the Puppy forum that users of the stock Puppy are having the same issue unresolved - http://www.murga-linux.com/puppy/viewtopic.php?t=48996)
I had to do that on a laptop to get it to boot and shut down properly.
