Sorry for completely dropping the ball on this, real life happened and I had to prioritise. My beginning "carreer" as a kernel developer was one of the things that ended up getting cut. I'm going to do a quick bug report while I'm writing an email here. I noticed on my Z830 that the readouts of the charge control thresholds didn't seem to work when I last tested it. Setting worked just fine, but reading it always returns 100%. Didn't get around to debugging this, but I assume it a simple error. Also my Z830 have developed a whole horizontal line of stuck red pixels across the middle of the screen, so it seems quite unlikely I'll use it much more or even keep it long term. > Neither the quickstart buttons, nor the touchpad-toggle button > which also uses the PNP0C32 interface, work to wakeup > the system from sleep though. This is probably a limitation of the hardware. Though there are IIRC some BIOS options for what should wake the laptop from power-off, including any keyboard press whatsoever. (Fun fact: The Toshiba ACPI interface allows changing these BIOS settings from the OS, though you would have to do it by hand from user space currently as it is not exposed in the driver.)
