I have a slackware system I have been using with the current install for about half a year. To shutdown I would exit my win manager (xfce, fluxbox, kde, and now gnome) get to command line change to root and then isssue the poweroff command. This would always work until lately...The command is interpreted and the 'this system is shutting down NOW" broadcast is sent....and nothing happens.

That's right, it just sits there, Ctrl-C, Enter, the powerswitch on my case do NOT work. What went wrong? Do I have a corrupt APM module? I do not think this would be the problem because the system does not even halt (or umount anything).

what shall i do?

You may try to put the following line in your /etc/lilo.conf file
apm=power-off

In Slackware you have to uncomment the APM module line in:

/etc/rc.d/rc.modules


All Best best with Linux.

Actually, right after I wrote this original post it started working again--very strange. Sorry for using your time.

Can anyone help? I tried to restart my PC, but all I get after the installation is this: ( I tried reinstalling Mandrake 10.1 but no progress, it's black screen with white writing of )

WHAT DOES THIS MEAN? CAN I BYPASS IT? ... ??? any suggestions are welcomed. Also where do you write the codes that change the configurations and stuff ( notice: I am a great newb with linux )
PS: it's driving me nuts! And I am very disappointed with linux ( my dream OS ).
- when I want to turn OFF the computer, I have to do so manually ( well b/c there's no other way, hehe! )
I have 512 MB ( DDR ram )
60 Gigs hard drive
32 MB Nvidia nForce 220
CD-RW drive
DVD-ROM drive
Floppy drive

There are a few different ways to shutdown your computer but the 'poweroff' command (usually needing root privledges by default) it probably the easiest/most common. If when you do this you system just halts put is still on you need to add APM (power managment to the BIOS) support in your kernel (usually as a module). Don't give up on Linux

How do I add APM (power managment to the BIOS) support in my kernel (usually as a module).
Thank you so much for responding.
