OK, this is REALLY wierd!
I got a PA-13 off Ebay, not a Dell one though. Awesome shipping, and has full year warranty which I might be using.
I removed the company dell ps from my I9300 and plugged in the PA-13....and when it's plugged in wierd stuff happens with input tools.
The Alps pad no longer functions, and the MS USB Mouse reacts slow, and auto selects things all the time.....
When I unplug the PA-13....all is normal again.
I emailed the seller.....this is just too wierd.....I should also mention it feels no cooler then my old PS either.
