Hi nothanksjustgo,

Thanks for posting.  Apologies for the difficulties with the application.

Here is information from the Dell knowledge base you may find helpful:

Dell command | power manager

Check to see that you've downloaded version 3.0  as the earlier version does not appear to be compatible with your system.

If you still require assistance and the system is under warranty, you may contact me privately. Be sure to include your personal information (name, address, telephone, email) and your computer's service tag number in your message. Thanks.

If there is no warranty, then you could contact our Out of Warranty team to get a quote for a paid service request. 

robertp,

no help,

only here for the money I guess
