Fresh CentOS 6.4 install on a Lenovo Thinkpad T430. Primary boot drive is a 256GB SSD.
When selecting System -> Shutdown -> Suspend. System suspends successfully for approximately two seconds then, with no user interaction, immediately wakes. Behaviour is the same when selecting System -> Shutdown -> Hibernate. Behaviour is the same when shutting the lid.
Here's an extract of /var/log/messages. See line 72 for the flip from shutdown state to startup state.

Any idea what could be triggering the wake command?
Thanks

Hi
Probably your PC was waken by RTC (a harware clock on the motherboard) managed by ACPI
Try command 'echo disk > /sys/power/state' to let your PC into hibernation, or 'echo mem > /sys/power/state' to syspend, if that behaviour still exists, it may be a bug of the BIOS
