Display assembly
NOTE: HP EliteBook 840 models offer both touch and non-touch displays. Non-touch displays are spared at
the subcomponent level only. Touch displays are only spared as a whole (touch display components are not
spared).
In non-touch models, you can remove the raw display panel with the display assembly still connected to the
computer. For more information, see
Display panel (non-touch) on page 69.
The following section shows how to remove the raw display panel without removing the display assembly
from the computer. See the display section later in this chapter to remove internal components that require
that you remove the display assembly.
