If you know your ThinkPad model does not 344 need to do NVRAM polling to support any of the hot keys you use, 345 unselecting this option will save about 1kB of memory. 346 347 ThinkPads T40 and newer, R52 and newer, and X31 and newer are 348 unlikely to need NVRAM polling in their latest BIOS versions. 349 350 NVRAM polling can detect at most the following keys: ThinkPad/Access 351 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute, 352 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12). 353 354 If you are not sure, say Y here.
