As title states. n5901 model. It does not come with driver CD or Holiday Stickers, unless I find the box by happenstance (I'll give it a try). Installs fine on Win7 x64 Pro as HID keyboard/mouse, works great (volume keys work too) but media keys do not.
Apparently this is a 3rd party, Lenovo branded and sold, product so Lenovo doesn't offer much support. I have decided to not support them.

This unit has less than 2 hours use. Sat on my shelf for about 3 months? (bought from Lenovo sale I found on woot) I have decided to buy a boxee remote instead. Will come with main unit, transmitter/receiver, and 2 AAA Energizer batteries (that came with unit).
