Be attention to the seal label and the humidity label.
The seal label (red oval) shown in the photo below is pasted on the screw securing the
motherboard. The tablet PC must have been disassembled when the seal label is broken or
removed.
The humidity label (yellow oval) is pasted on the motherboard. The color of the humidity label
shows the humidity of the tablet PC. The original color of the humidity label is white (This color
shows that the tablet PC is dry). The color of the humidity label turns to pink when the tablet PC
is wet.
