That's because what I instructed in #15 makes laptop-mode-tools

Not really.
The BX100 has broken LPM, it's not working under min/med power.
The MX300 in askubuntu.com does have a working LPM, just unimaginably
slow.
I'll build a kernel with the workaround I used in comment #30, fallback

This would still be a flaky device or a kernel bug. Because the
