Thank you Gallium. I have a Intel(R) Core(TM) i5-4210H CPU @ 2.90GHz (4 CPUs), ~2.9GHz, so it looks like I have an R1.  I have to replace a keyboard key and I needed to know this information.

You have the 15 R1 that shipped on January 27, 2015. The purchased warranty expired on February 11, 2018. DELL-Admin
