Hi anyone there can telle me about which stylus pen I can use for zps15 - 9510 - and can I draw on the screen?
This is not a 2-in-1 tablet/notebook - it's not designed for an active pen.
If that's what you want in a 15" system, you need the Inspiron 7506 2-in-1.

The only XPS model with active pen support is the 13" 9310 2-in-1.

There is no current 15" XPS 2-in-1 -- the last one was a few years ago.
