Any chance you can update your BIOS?

BIOS Information
    Vendor: LENOVO
    Version: 4BCN20WW
    Release Date: 04/15/2011

latest on lenovo web site is 17 Aug 2011.

(unfortunately, it appears to be a .exe that you'd run in Windows --
 if you've got a windows partition, simple, otherwise, maybe not simple)

The reason that I ask is that the last stages of powerdown
are handled by the BIOS, and so sometimes there is a BIOS
dependency.

BTW. does reboot also fail, or is that more reliable than powerdown?
