Caffeine

Prevent your computer from going to sleep

If you accept problems with your PC locking or going to sleep, caffeine volition go along it awake. It works past simulating a keypress once every 59 seconds, so your machine thinks yous're notwithstanding working at the keyboard, so won't lock the screen or activate the screensaver.

The icon is shown above - it'southward the leftmost one in the task tray, and this is all yous run into. Double-clicking the icon empties the coffee pot (that'due south what the icon is) and temporarily disables the program. Double-clicking it over again refills the pot, and will go along your motorcar awake.

By default the app starts enabled, and works every 59 seconds. At that place are some command line switches you tin can use to alter this behaviour:

• xx - where xx is a number which sets the number of seconds between simulated keypresses. This must be the first text on the commandline
• -startoff - application starts disabled.
• -exitafter:xx - application will cease after twenty minutes
• -activefor:xx - awarding volition become inactive subsequently twenty minutes
• -inactivefor:xx - application will become agile after xx minutes
• -appexit - terminates current running example of application
• -appon - makes the current running instance of the application active
• -appoff - makes the current running case of the awarding inactive
• -apptoggle - toggles the running state of the current running instance of the application
• -apptoggleshowdlg - toggles the running state, and shows dialog
• -replace - closes the current running instance, replacing it
• -noicon - does not show a task tray icon
• -useshift - simulate the shift fundamental instead of F15
• -allowss - prevent slumber, but permit the screensaver to get-go
• -stes - tell Windows to stay awake, don't use F15
• -showdlg - shows a dialog indicating whether caffeine is active
• -ontaskbar - evidence a job bar push button (utilize with -showdlg)
• -primal:xx - simulate using virtual primal code xx
    Annotation: the codes on the linked page are in Hex, convert them to decimal for use with this parameter
• -keypress - simulate a full key printing, not just a key up event
• -oldicons - use more colourful tray icons
• -lighticons - e'er use the light icons
• -darkicons - e'er employ the nighttime icons
• -watchwindow:xx - active only when a window with xx in the title is establish
• -activehours:........xxxxxxxx........ - put 24 . or x characters - which signal from hr 0 to hour 23 of the day. Caffeine will be active just in hours with an x
• -onac - active only when the estimator is on Air conditioning power (plugged in)

Comparison of methods

Command line	Caption
empty	The F15 'key upwards' issue is used every 59 seconds. This is the traditional behavior and so is well tested, but can cause issues with Putty sessions, PowerPoint, Google Docs or Smartsheet
-useshift	Instead of F15, the shift key is used. This solves some of the issues with the to a higher place apps, just may cause the shift key to become "unpressed" sometimes
-central:xx	Instead of F15, the primal specified by xx is used. Your choice of key could have side furnishings
-keypress	This is more likely to cause side effects, every bit a full key down/key up is generated. It's included for compatibility with older systems which might need this
-stes	Uses a dissimilar method (calling SetThreadExecutionState to tell Windows not to sleep. It works for me, with no side effects, but hasn't had enough testing for me to sure it's entirely amend than using F15. Note that this will keep the machine awake, but not simulate activity, meaning any app which tracks user input will not see any.
-allowss	The same as -stes merely this fourth dimension the screensaver can start. Annotation that this will keep the machine awake, but not simulate activity, meaning whatever app which tracks user input volition non see whatever.
