Dell Wyse ThinOS Version 8.6 and ThinOS Lite 2.6 Operating System Release Notes

Sleep mode

The sleep mode enables the power-saving state and the thin client resumes power without loss of data.

• ThinOS VDI broker session logs off after resuming from sleep mode for security. You must log in to the broker session again after resuming from sleep mode.
  NOTE: If you do not want to lose VDI sessions or to login to broker again, it is recommended to disable sleep mode by using the INI parameter Sleep=no.
• The device automatically enters sleep mode when ThinOS is idle for 20 minutes. This value is the default value. You can set the idle time in the System Preferences dialog box.
• To enable the thin client to automatically enter the sleep mode, set the Turn Off Screen as screen saver. Sleep mode timer starts after screen is turned off by the screen saver.
• As the Wyse 5470 All-in-One thin client does not have a battery, plugged in is always selected.
• To manually enter sleep mode, open the ThinOS shut down menu, select the Sleep option, and click OK.

  • Press the power button.
  • Click the USB mouse or move the wireless USB mouse.
