 431           Overriding LED state on ThinkPads can mask important

 434           the bay while buses are still active), etc.
 435
 436           LED control on the ThinkPad is write-only (with very few
 437           exceptions on very ancient models), which makes it
 438           impossible to know beforehand if important information will

 465

 814          Enable support for IBM Premium Real Time Mode (PRTM).
 815          This module will allow you the enter and exit PRTM in the BIOS via
 816          sysfs on platforms that support this feature.  System in PRTM will
 817          not receive CPU-generated SMIs for recoverable errors.  Use of this
 818          feature without proper support may void your hardware warranty.
 819
 820          If the proper BIOS support is found the driver will load and create
 821          /sys/devices/system/ibm_rtl/.  The "state" variable will indicate
 822          whether or not the BIOS is in PRTM.

 909           automatically copying memory contents to disk. On resume, the

 919           intervals. If a user enables this functionality under Windows and
 920           then reboots into Linux, the system may remain configured to resume
 921           on suspend. In the absence of any userspace to support it, the system
 922           will then remain awake until something triggers another suspend.
