CentOS - Nov 2012 - Centos 6: Dell GX270 fails to power down (but reboots)

Hi,

am using latest C6 on a Dell GX270 with latest Bios.
It fails to power down but restarts when running
$ sudo poweroff

I tried some google hints for kernel boot option:
acpi=force
no help, looks like acpi is working anyway when looking in dmesg
acpi=off
makes e1000 nic fail to initialize

Any suggestions?
Rainer

Just stabbing in the dark: do you have acpid installed?

Isn't this the Optiplex-modells that were a bit quirky and also had leaky 
capacitors on the motherboard?

Anyway, have you tried updating the BIOS?

Update the BIOS.  Should fix it.  We had this issue a while back and the new
BIOS corrected the issue.

Thx for all your answers, but latest Bios is installed (A07 from year 2006).
The pc is has not crashed so far, except the poweroff thingy so I guess 
hw is ok.
FWIW under C5 all was well.

A wild shot; if you have physical access to the computer, could you please 
open it up and check the capacitors, especially around the cpu?
