Hmm... I must add this to my mental FAQ when people ask anything about power buttons: -----8<----- ACPI power buttons often have safety timers, and they are ~1s, ~4s and ~10s in a ThinkPad. A quick press will be ignored by the firmware. You need to hold it pressed for some time for something to happen. The ~1s/~4s safety time varies. Some times it wants 1s, some times it wants 4s. If you press a power button it and it is ignoring the press, try to hold it down for at least four seconds. Holding the power button down for too long (about 10s), instructs a ThinkPad embedded controller to power down the main CPU by force. Don't do this often. -----8<----- -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
