ThinkPad laptops include a proprietary interface called SMAPI BIOS (System Management Application Program Interface) which provides some hardware control functionality that is not exposed by any other interface (e.g., ACPI).

The SMAPI interfaces has mutated between models and is poorly documented, so Linux support is not exhaustive for most models. There are currently two SMAPI access mechanisms available:

  • tp_smapi for newer ThinkPad models (extended battery information for models produced since 2001 and possibly earlier; additional features for models produced since 2003)
  • tpctl (with the thinkpad kernel module) for older ThinkPad models (mostly superceded by ACPI, when available)
