Why Does the Screen Go Black After 90 Seconds on the Intel® NUC® M15 Laptop Kits - LAPBC710 & LAPBC510


Windows® 10, 64-bit*


How to keep the display from automatically dimming.


The Intel® NUC M15 Laptop Kit display dims after 30 seconds and 60 seconds later (for a total of 90 seconds) the screen goes completely black if there is no one in front of the system. The 90-second countdown timer begins when the Intel NUC M15 Laptop Kit's Time of Flight sensor (A) does not see anyone/anything in front of the sensor.

The Time of Flight sensor has been incorporated into Intel® NUC Software Studio as several User Presence Detection options. When the Intel® NUC M15 Laptop Kit is connected to the Internet for the first time, Intel's NUC Software Studio (NSS) will automatically be loaded, but if it doesn't automatically load, open the Microsoft* Store, search and download, Intel® NUC Software Studio.

Refer to the User Guide page 11 to learn more about user presence detection.
