444           Overriding LED state on ThinkPads can mask important
445           firmware alerts (like critical battery condition), or misled
446           the user into damaging the hardware (undocking or ejecting
447           the bay while buses are still active), etc.
449           LED control on the ThinkPad is write-only (with very few
450           exceptions on very ancient models), which makes it
451           impossible to know beforehand if important information will
452           be lost when one changes LED state.

493           need to do NVRAM polling to support any of the hot keys you use,

497           unlikely to need NVRAM polling in their latest BIOS versions.

944           This driver provides support for modifying paramaters on systems
945           equipped with Intel's Rapid Start Technology. When put in an ACPI
946           sleep state, these devices will wake after either a configured
947           timeout or when the system battery reaches a critical state,
948           automatically copying memory contents to disk. On resume, the
949           firmware will copy the memory contents back to RAM and resume the OS
950           as usual.
953         tristate "Intel Smart Connect disabling driver"
954         depends on ACPI
955         ---help---
956           Intel Smart Connect is a technology intended to permit devices to
957           update state by resuming for a short period of time at regular
958           intervals. If a user enables this functionality under Windows and
959           then reboots into Linux, the system may remain configured to resume
960           on suspend. In the absence of any userspace to support it, the system
961           will then remain awake until something triggers another suspend.
963           This driver checks to determine whether the device has Intel Smart
964           Connect enabled, and if so disables it.
966 config PVPANIC
