Power button LED behavior
On certain Dell Latitude systems, the power button LED is used to provide an indication of the system status, and as a result the power
button illuminates when pressed. The systems with the optional power button/fingerprint reader will have no LED under the power button
and hence will apply the available LED's in the system to provide an indication of the system status.
