Laptop LCD display powers off when near other systems

You may encounter a situation where the display on a notebook or tablet system powers off when stacked on top of or in close proximity of other units.

 


Solution

This functions is by design and there is no way to disable this feature.

The systems have a magnetic switch in the palmrest (also known as a reed switch) that will turn the display off when the LCD lid is closed. This may also occur when another magnet is in close proximity (Roughly one inch) to the systems magnetic switch. (Example: a money clip in a pants pocket with a magnet on it).

Ultra thin systems are more susceptible to effect of magnets in other systems or in close proximity to the system because of the thin chassis design. (Latitude E6430u Ultrabook, XPS13, Latitude 13 or other ultra thin units.)

This issue effects the display only, the system is still powered on. If the systems must be stacked, a one inch (1") spacer material between each system should prevent the issue from occurring.

NOTE: Dell does not recommend or support stacking multiple notebook systems on top of one another, as that could lead possible system damage.
