HP ENVY 17.3" Intel i7 Quad-Core Laptop

As ThunderThighs posted above, the keyboard isn’t backlit, no. We’d note that feature if it were included.

What’s the difference between this modle and the 17 inch M7 seriers. and This modle seems a little heavier than the M7. why?

I think the weight is listed incorrectly. Hp shows this weighs 6.1lbs. The m7 weighs almost 1lbs more
