In the latest V-series bios DMI_PRODUCT_VERSION does not contain the string Lenovo or Thinkpad, but is set to the model number, this causes the thinkpad_acpi module to fail to load. Recognize laptop as Lenovo using DMI_BIOS_VENDOR instead, which is set to Lenovo. Test on V490u ============= == After the patch == [ 1350.295757] thinkpad_acpi: ThinkPad ACPI Extras v0.24 [ 1350.295760] thinkpad_acpi: http://ibm-acpi.sf.net/ [ 1350.295761] thinkpad_acpi: ThinkPad BIOS H7ET21WW (1.00 ), EC unknown [ 1350.295763] thinkpad_acpi: Lenovo LENOVO, model LV5DXXX [ 1350.296086] thinkpad_acpi: detected a 8-level brightness capable ThinkPad [ 1350.296694] thinkpad_acpi: radio switch found; radios are enabled [ 1350.296703] thinkpad_acpi: possible tablet mode switch found; ThinkPad in laptop mode [ 1350.306466] thinkpad_acpi: rfkill switch tpacpi_bluetooth_sw: radio is unblocked [ 1350.307082] Registered led device: tpacpi::thinklight [ 1350.307215] Registered led device: tpacpi::power [ 1350.307255] Registered led device: tpacpi::standby [ 1350.307294] Registered led device: tpacpi::thinkvantage [ 1350.308160] thinkpad_acpi: Standard ACPI backlight interface available, not loading native one [ 1350.308333] thinkpad_acpi: Console audio control enabled, mode: monitor (read only) [ 1350.312287] input: ThinkPad Extra Buttons as /devices/platform/thinkpad_acpi/input/input14 == Before the patch == sudo modprobe thinkpad_acpi FATAL: Error inserting thinkpad_acpi (/lib/modules/3.2.0-27-generic/kernel/drivers/platform/x86/thinkpad_acpi.ko): No such device Test on B485 ============= This patch was also test in a B485 where the thinkpad_acpi module does not have any issues loading. But, I tested it to make sure this patch does not break on already functioning models of Lenovo products.
