[PLUG] no power off after shut down

[bp]

Hello,

I have installed mandriva 2008 on p4 pc. I checked that acpi service is on. 
Also acpid is running.

When I shut down  the  machine, it halts but  do not power off automatically.

Earlier mandrake 9.1 was on the same machine and  automatic power  off was 
working.

I checked in setup also. As it is dual boot for testing, from other OS after 
shut down power went off, means from setup point  things are right.

What can be the cause? I tried many ways, net, books etc.
Any pointer will be of great use.
