7. Before replacing the LCD panel, ensure that the correct magnet is
installed in the magnet holder.
A magnet switch causes the computer to go into suspend mode when the
display is closed. Failure to install the correct magnet in the magnet holder
may prevent the computer from going into suspend mode. Begin by
checking the back of the LCD panel for the manufacturer’s label, and then
follow the instructions for that manufacturer.
Sharp LCD Panel
Some revisions of the Sharp LCD panel have a magnetic frame and
require a single, large magnet, or two small magnets with no foam spacer,
for the magnet switch to operate properly. Other revisions of the Sharp
LCD panel have a nonmagnetic frame and require a single, small magnet
with a foam spacer. To identify the revision of the LCD you are working
with, follow these steps:
a. Remove the magnet from the magnet holder (see Figures 19 and
20), and place it against the replacement LCD panel frame.
b. If the magnet sticks, the LCD panel has a magnetic frame. Place a
single, large magnet, or 2 small magnets with no foam spacer, in the
magnet holder.
c. If the magnet does not stick, the LCD panel has a nonmagnetic frame.
Place a single, small magnet and a foam spacer in the magnet holder,
as shown in Figure 20. Place the magnet to the left of the foam spacer,
assuming you are facing the display as shown in Figure 19.

Samsung LCD Panel
Place a single, small magnet and a foam spacer in the magnet holder, as
shown in Figure 20. Place the magnet to the left of the foam spacer,
