== Pinebook Pro will not sleep with lid closed ==
A problem with the positioning of the lid magnet has been identified by several forum users in mid-2020 models of the Pinebook Pro. The magnetic field from the lid magnet operates a hall effect sensor located on the daughterboard (smallboard), which causes the Pinebook Pro to sleep when the lid is closed. If the magnet is not positioned correctly, the Pinebook Pro will not sleep when the lid is fully closed, but may sleep if the lid is open about an inch. If you experience this problem, repositioning of the magnet may be necessary.
=== Lid Magnet Repositioning Step-by-Step ===
*Read these steps thoroughly before starting. This is a somewhat laborious process involving fragile parts!
# Remove bottom cover.
# Disconnect LCD and webcam ribbon cable from main board. Flip the small black strip on the connector upward and the ribbon cable can be easily removed. Do not pull the cable out without first raising the black retaining mechanism.
# Remove the small black plastic standoffs on each hinge and set aside.
# Remove the three screws from each hinge on the display assembly.
# Move the hinges upward to a 90 degree angle independently from the main body. Then lift the main body to the same 90 degree angle and you should be able to separate the display assembly from the main body. Set the main body aside.
# Remove the plastic hinge cover on the display assembly. There's not really an easy way to do this, just work slowly and deliberately so as not to damage the sensitive cable inside. Start from either end and work your way inward. Use a small flathead screwdriver or similar tool to get started.
# Remove the hinges from the display assembly.
# Remove the rubber bumpers at the top corners of the display assembly to expose two screws. Remove the screws.
# Starting at the corners, separate the bezel from the lid. The clips that hold it in place are similar to those found on the hinge cover. Again, slow deliberate work will get it done. Work from the top down. Take care not to damage the cables in the bottom.
# With the bezel separated from the lid, feed the cable through the slot and set the bezel aside.
# Without removing the LCD panel completely, lift and move the panel slightly to the left, taking care not to damage the cable running underneath up to the webcam. This will give you room to remove the magnet without risking damage to the panel.
# The magnet is a silver colored bar near the bottom right side of the lid. Pry the magnet out with a small flathead or similar tool and set it aside. There is some adhesive but it's not very strong.
# Put the LCD panel back where it belongs. Note the foam pads on either side of the panel. The magnet is the same width as the foam pad that keeps the panel in place, and should fit perfectly in the same channel.
# The magnet should be placed about 1 to 1.5cm lower than where it was originally. There should be no need for adhesive, as the magnet will stick to the LCD panel. For reference, the hall effect sensor that the magnet interacts with is in between the USB port and audio jack.
# Reassemble using these steps in reverse order.
Your PineBook Pro should now sleep properly when the lid is closed.
