#HID KEYBOARD DEVICE DRIVER ERROR ON MY TOSHIBA SATELLITE WINDOWS#
I will continue working on this issue because the back-light is not the only feature on my TOS1900 device that is currently only fully available on windows (proper fan control, processor power save. There is one other bit on the embedded controller that I currently have a hunch about, but unfortunately there is no convenient method in the ACPI DSDT for my system. KBBT, 6, /* Keyboard Backlight - Timer */ KBBL, 1, /* The bit I have a hunch about.

KBBM, 5, /* Keyboard Backlight - Mode (On, Timed or Off) */ LEDO, 1, /* Illumination LED (already handled by toshiba_acpi) */ HKHS, 1, /* Unknown - TOI1 = 0x1E (I haven't translated this yet) */

I wrote a little code segment that allowed me to set the appropriate bits using acpi_evaluate_object, this allowed me to 'turn on' the keyboard back-light and set the back-light time-out, these changes are visible in the system bios and work when windows is booted however the actual back-light does not turn on. This feature on the TOS1900 device is separated from the illumination LED and writes to a different part of the embedded controller responsible for back-light and other useful features. When a key is pressed again, the back-light will turn back on. On my laptop, the toshiba_acpi driver doesn't seem to cover Toshiba's back-light with the TOS1900 device, only the illumination LED (around the mouse).įrom what I can gather about Toshiba's newer laptops, they include a keyboard back-light timer that will dim/turn off the keyboard back-light if no key is pressed for a while. I have been looking into this issue on another laptop in the P750 series. But it's nice to finally have a use for that Windows system I paid for as part of the laptop. I don't know why the abnormal Windows shutdown causes this to remain enabled in Linux, while the normal Windows shutdown does not. I'd originally tried that and found it worked, but wiped out my Linux installation once when restarting after the hibernate. I've seen reference to using Windows hibernate rather than a power-off for the same purpose. If this happens I'm back to the original state. Once I've done this procedure the backlight continues to operate until I completely shut off power to the laptop (no battery or completely dead battery, no line power). The backlight timeout works properly, too, so if you don't hit a key for the set timespan the light goes out until you do hit another key. If I restore the original harddrive and boot Windows, then turn off the laptop with the power switch (not going through Windows shutdown), switch back to my SSD and reboot into Linux, the keyboard backlight stays on (so does the Toshiba illumination light, but you can turn this off in the BIOS before booting into Linux without any problem).

I replaced the harddrive that came with the system with an SSD containing my Linux installation (currently OpenSuse 12.2). However, you can make it work (at least I can, on my Satellite P750D) with some trickery. The keyboard backlight is initially on when you turn on the laptop (if enabled in BIOS), but if you have ACPI enabled it normally shuts off as soon as you start to boot into Linux (immediately after the GRUB boot screen). Here's some more details on the problem and a hardware workaround. Meanwhile, the bug is definitely not fixed.
