Lenovo Yoga 2 13.3" QHD+ Touch Ultrabook

What is the model number on this computer?

Not sure of the model number, but it is the Yoga 2, not the newer Yoga 3.

Specs are still good with 8GB RAM and 256 GB SSD. It has an older i5 processor, but should still be plenty fast for most normal users. Web browsing, e-mail, office software, etc
