v10.0 Shutdown Problem

New installation on an IBM T20 Laptop went well without any problems. There is, howeer, one exception. When I shutdown the system as a u8ser in KDE it goes well until time to shut off the computer - then nothing happens. It is necessary to cut the power manually. Suggestions for a solution will be welcome. Thanks in advance. -- Stephen P.
