UPS set-settings\r\n tings also have an on\/off value. Use a -1 argument instead of percent or\r\n minutes to turn any of these settings off. If multiple halt conditions\r\n are specified, the system will halt on the first condition that occurs in\r\n a low power situation.\r\n\r\n haltlevel - when draining UPS battery, battery level at which to trigger\r\n an emergency shutdown (value in %)\r\n haltafter - when draining UPS battery, trigger emergency shutdown after\r\n this long running on UPS power (value in minutes)\r\n haltremain - when draining UPS battery, trigger emergency shutdown when\r\n this much time remaining on UPS power is estimated (value in minutes)\r\n\r\nSCHEDULED EVENT ARGUMENTS\r\n pmset allows you to schedule system sleep, shutdown, wakeup and\/or power\r\n on. \"schedule\" is for setting up one-time power events, and \"repeat\" is\r\n for setting up daily\/weekly power on and power off events. Note that you\r\n may only have one pair of repeating events scheduled - a \"power on\" event\r\n and a \"power off\" event.\r\n\r\n type - one of sleep, wake, poweron, shutdown, wakeorpoweron\r\n date\/time - MM\/dd\/yy HH:mm:ss (in 24 hour format)\r\n time - HH:mm:ss\r\n weekdays - a subset of MTWRFSU (\"M\" and \"MTWRF\" are valid strings)\r\n owner - a string describing the person or program who is scheduling this\r\n one-time power event (optional)\r\n\r\nOTHER ARGUMENTS\r\n boot - tell the kernel that system boot is complete (normally LoginWindow\r\n does this). May be useful to Darwin users.\r\n force - tells PM to immediately activate these settings. Does not write\r\n them to disk, and the settings may easily be overwritten. Useful in cir-circumstances\r\n cumstances where PM's configd plugin happens not to be running.\r\n dim - deprecated in 10.4 in favor of 'displaysleep'. 'dim' will continue\r\n to work.\r\n spindown - deprecated in 10.4 in favor of 'disksleep'. 'spindown' will\r\n continue to work.\r\n\r\nEXAMPLES\r\n pmset -b displaysleep 5\r\n\r\n pmset -a displaysleep 10 disksleep 10 sleep 30 womp 1\r\n\r\n pmset -u haltlevel 40\r\n\r\n pmset -g\r\n\r\n pmset -g batt\r\n\r\nFiles\r\n All changes made through pmset are saved in a persistent preferences file\r\n (per-system, not per-user) at\r\n \/Library\/Preferences\/SystemConfiguration\/com.apple.PowerManagement.plist\r\n\r\n Scheduled power on\/off events are stored separately in\r\n \/Library\/Preferences\/SystemConfiguration\/com.apple.AutoWake.plist\r\n\r\n pmset modifies the same file that System Preferences Energy Saver modi-modifies.\r\n fies.\r\n\r\nDarwin August 19, 2002 Darwin\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"If you are having issues with your Powerbook waking up at the wrong time (in your backpack for instance) because the lid latch is weak, then run the following command from a concole window: sudo pmset lidwake 0<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[6],"tags":[],"_links":{"self":[{"href":"https:\/\/www.hoodedhawk.com\/blog\/wp-json\/wp\/v2\/posts\/188"}],"collection":[{"href":"https:\/\/www.hoodedhawk.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hoodedhawk.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hoodedhawk.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hoodedhawk.com\/blog\/wp-json\/wp\/v2\/comments?post=188"}],"version-history":[{"count":0,"href":"https:\/\/www.hoodedhawk.com\/blog\/wp-json\/wp\/v2\/posts\/188\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.hoodedhawk.com\/blog\/wp-json\/wp\/v2\/media?parent=188"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hoodedhawk.com\/blog\/wp-json\/wp\/v2\/categories?post=188"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hoodedhawk.com\/blog\/wp-json\/wp\/v2\/tags?post=188"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
