Hello, I own a ThinkPad SL510 for 9 months now. Machine has several problems, most important completely broken suspend, but it's not bad otherwise. I owned worse. Now when I bought it thinkpad_acpi was not loading, having some hybrid IdeaPad firmware it reported "not yet supported ThinkPad detected". Neither hdaps or tp_smapi were loading as wel... Anyway I found the lenovo-sl-laptop project, but it has no support for SL510, only SL500, and author never replied to any of my e-mail. Then I found asus-laptop has some support for the SL and I made a feature request here: http://dev.iksaif.net/issues/27 They were kind to inspect my DSDT and said there's no way to add support. So without any drivers the state is: no fan control, quirky backlight but usable (brightness resets on each boot or X restart), no auto mute when headphones are plugged in (I mention it because I saw this driver has some audio control) and finally, most extra buttons do not work. Working buttons: vol up, vol dn, mute, fn+f4 suspend, brightness up, brightness dn. Not working buttons: hibernate, screen zoom, screen lock, microphone wifi bluetooth touchpad toggles, battery status and the ThinkVantage button. Yesterday by chance I read a claim on some forum "thinkpad_acpi has experimental SL support". I thought it rubbish, but the driver loaded to my surprise. I run Linux 2.6.36.2 and the output was: thinkpad_acpi: ThinkPad ACPI Extras v0.24 thinkpad_acpi: http://ibm-acpi.sf.net/ thinkpad_acpi: ThinkPad BIOS 6JET77WW (1.35 ), EC 6JHT59WW-1.179000 thinkpad_acpi: Lenovo ThinkPad SL510, model 28476LG thinkpad_acpi: detected a 8-level brightness capable ThinkPad thinkpad_acpi: radio switch found; radios are enabled thinkpad_acpi: possible tablet mode switch found; ThinkPad in laptop mode thinkpad_acpi: asked for hotkey mask 0x078dffff, but firmware forced it to 0x008dffff thinkpad_acpi: rfkill switch tpacpi_bluetooth_sw: radio is unblocked Registered led device: tpacpi::thinklight Registered led device: tpacpi::power Registered led device: tpacpi::standby Registered led device: tpacpi::thinkvantage thinkpad_acpi: Standard ACPI backlight interface available, not loading native one. thinkpad_acpi: Console audio control enabled, mode: monitor (read only) input: ThinkPad Extra Buttons as /devices/platform/thinkpad_acpi/input/input9 I keep upgrading the BIOS in hope they will fix the damn suspend. So since the above I upgraded from 1.35 to 1.41 BIOS which is latest, also before I dump DSDT and DMI for this request. They are attached to the message. Modprobing thinkpad_acpi made all (or nearly all) extra keys working. This alone is enough for me wanting to use thinkpad_acpi. I'm sold. But it also had side effects, i.e. the Mute button stopped muting the volume and its LED would not light on. I'd love to see the support improving a little. And thank you for making it possible to work at all! -- Adrian C. (anrxc) | anrxc..sysphere.org | PGP ID: D20A0618 PGP FP: 02A5 628A D8EE 2A93 996E 929F D5CB 31B7 D20A 0618
