Tips - Missing "Dell System and Device manager" and "Dell Power manager"

After reinstalling Windows I cant find 2 dell applications within dell drivers and downloads. Applications were preinstalled on the dell computer by delivery. Can any one help with a link for downloading those applications?
Applications which I am missing is:

* Dell System and Device manager
* Dell Power manager


Look up a lattitude E5520, then search for alll drivers under Vista 64. For some reason it's not listed under windows seven. The catogory is Control Point and it will be the only download.
