Description
Hello,
I bought an SL510. Found that SL have IdeaPad firmware and thinkpad_acpi won't work. Then I found lenovo-sl-laptop project which failed to work:
lenovo-sl-laptop: Failed to get ACPI handle for \_SB.PCI0.SBRG.EC0.HKEYFurther reasearch brought me to this commit: asus-laptop: add Lenovo SL hotkey support
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=14f8af31But asus-laptop on my Linux 2.6.33.2 also fails to load. How can I get these SL510 supported (if at all) by asus-laptop?
For a start my machine is:
sys_vendor = "LENOVO"
sys_product = "28476LG"
sys_version = "ThinkPad SL510"
bios_version = "6JET58WW (1.16 )"
The SL510 machines do work OK with 2.6.33.x linux, but with certain limitations; backlight is quirky with acpi's video, and more than half of the extra keys are invisible to the kernel (hibernate, microphone, zoom, wifi/screen/bluetooth/touchpad toggles, lock, battery status...).
Thank you.

Hi !
Easy to know, could you send me your dsdt ? (use acpidump).
Thanks

Hello,
attached is the acpidump output, not raw from /proc/acpi.
I updated my firmware last night, it is now "6JET73WW (1.31)". I was hoping it will fix suspend (machine can't wakeup at all), but that's another story...
Thank you for looking into adding support.

After reading your dsdt:
- asus-laptop can't support this laptop, it does not provide the needed acpi interface.
- there is a wmi interface, but none of the wmi drivers in drivers/platform/x86/ handle it. It's probably the only way to add missing hotkeys.
What you can do is post your request on:
- Lenovo Consumer Support
- your distribution forum/bug report tool
- platform-driver-x86@vger.kernel.org, linux-acpi@vger.kernel.org, linux-kernel@vger.kernel.org
And maybe someone will start working on it. (I could probably do it, but it's not easy working on hardware you don't have)

Unfortunately a tricky situation. Most of these things happen when someone has an itch to scratch, how things are done in the GNU/Linux land :) I hope there will be more owners of this model, and I really hope that some other Lenovo laptops have the same interface... after a while maybe a lenovo/thinkpad-sl-wmi driver will emerge.
Thanks for looking into this.
