Hello,
Thank you for your interest in the Dell S2440L IPS monitor. The Power On/Off button is located on the very bottom right corner of the monitor bezel. Use the Power button to turn the monitor On and Off. The white light indicates the monitor is On and fully functional. An amber light indicates the power save mode.
