Meaning of DADAPP in English
Dell AccessDirect Applet. Background task found on Dell laptops and which implements the programmable buttons that you can set up for your laptop. The setting up of those buttons is done via the Access Direct software which you can start either from the Dell Applications icon in the Control Panel, or from the Dell AccessDirect icon in the System Tray (DADTRAY).
Unless you see yourself using the programmable keys, you can disable this task with Startup Manager. Note, however, that once you disable it, if you decide at a later stage to re-enable it you will in most cases need to program again your programmable keys with the Access Direct software as in our experience the settings seem to get lost when DADAPP is disabled.
