Hi!
Exactly the same happens with my Clevo D610SU. There is a register which
should (probably) activate the Message LED, which is otherwise non-functional.
I've tried my best to write the register, but neither the value can be changed
(always 0), nor the LED does anything special.
With regards, Pavel Troller
