The Kensington Power Adapter K38047US Does not work with the Mini
Apparently Kensington missed the fact that the Mini and Mini-Note actually use different power tips.
The Mini-Note (business version) uses the same size power tip as most of HP's other laptops
The Mini (consumer version) uses a much smaller power tip.
Kensington only includes the larger tip, but lists it as working for both the Mini & Mini-Note on package.
I call their 800 # and the guy I talked to wasn't helpful. (Other than saying send it back.)
He showed no interest in making sure the correct size tip was made available.
