I tried with the battery inserted, in case that messed up something, but
the only differences are hw.acpi.battery.state (2 instead of 7), and
temperature and fan speed readings.

I tried that (well 15s actually), and I haven't seen any difference.
Is there a more definite way to test whether it is the case?

So the UEFI BIOS claims to have version 8DET58WW (1.28), dated as
2012-02-14, while EC versions claims to be 8DHT29WW (1.13).
According to leveno website, that's two releases behind. I will try to
update it, despite my uneasiness caused by previous bad experiences.
Still I'm not exactly sure how to perform it, since I inadvertently
destroyed the Windows pre-installation, and I have no optical drive.
Though I will probably try with CURRENT instead of STABLE before trying
BIOS update, since it's much easier to perform and I only need time to
get at it.
