Oh, that's still the problem of _BCL not getting executed once for
Lenovo thinkpad laptops. I borrowed a Thinkpad X1 this afternoon and can
reproduce this, I'll take a look at this issue. The thinkpad-acpi module
already has a call to _BCL but somehow that doesn't happen.

Since it's national holidays here, I'll check this issue when I got back
to work on this Saturday. Thanks for the quick test :-)
