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. > If the EC is crashed, the fix used to be removing battery, holding power > button for 10 seconds and reinstalling battery...I usually see this > stuff on Macbooks, but, I suppose it's possible the EC is in an > "unplanned" state and thus has corrupted some values...many of the ACPI > calls query the EC. 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? > It's also possible you are running an old bios?

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.
