Based on reported quality failures, primarily in school districts, Dell is asking customers in the Education Segment (K12) to stop using the 3-position duckhead connector and use a standard power cord to connect the AC Adapter to the power outlet.
This occurs because the KACE K2000 appliance uses Windows Pre-installation Environment 3.0 (Win PE 3.0) and the Venue 11 Pro 7130/7139 tablet external keyboard support only works on Windows Pre-installation Environment 5.0 (Win PE 5.0).
Once the download finishes just double click on the files to run them. Ubuntu Software Center will open up like the below example. Click the install button (the oem-kernel-cmdline patch will say update).
