crystal displays (color LCDs). Therefore, if 0.002% or less of the picture elements either

fail to light or remain constantly lit (that is, more than 99.998% of elements are function-

ing properly), no defect is considered to exist.

When an external display not compatible with the power saving mode is used with the

computer, the external display may no longer display properly when the computer enters the

condition the power of the display is off (for energy conservation purposes). In such cases,

turn off the power to the external display.
