Fix reset value in Lenovo ThinkPad 13 config (#604)

I see that my e580 seems to behave in the same way, and I think this is a bug:
Author of this config probably wanted to set 80 as hex not as decimal.

on my device this is what happens on exit:
hex 80 = dec 128 => factory auto mode
hex 50 = dec 80   => full speed of fan
