An indicating device of a portable computer is disclosed. The indicating device utilizes a light guiding board to guide the light emitted from LEDs to indicate different status of the portable computer. The light guiding board includes the first, second, and third surfaces. The light emitted from LEDs is received by the first surface, further reflected by the second surface, and then sent out through the third surface to form a diffusion light and to show the status of the computer.

1. A status indicating device of a portable computer, wherein the status indicating device indicates a plurality of statuses of the portable computer, comprising:
a plurality of light emitting diodes, which emit light corresponding to each status; and
a light guiding board having a first, a second,
1. A status indicating device of a portable computer, wherein the status indicating device indicates a plurality of statuses of the portable computer, comprising:
a plurality of light emitting diodes, which emit light corresponding to each status; and
a light guiding board having a first, a second, a third, a fourth, a fifth and a sixth surface, said first, second, third and fourth surfaces collectively forming an edge of said light guiding board,
wherein each of said first, second, third and fourth surfaces has a rectangular shape, said first surface being contiguously connected to said second surface and to said third surface, said first surface and said third surface forming a right angle, and said first surface and said second surface forming an acute angle, said first surface and said fourth surface being parallel to each other, and
wherein said fifth surface and said sixth surface are each trapezoidally-shaped, are arranged parallel to each other, and are disposed perpendicular to said first, second, third and fourth surfaces, each of said first surface, said second surface, said third surface and said fourth surface being connected to respective edges of each of said fifth and sixth surfaces;
said light guiding board guiding and diffusing the light emitted by the diodes and indicating the status, wherein said first surface receives the light emitted from the LEDs;
said second surface reflects the light received by said first surface; and
the light reflected by said second surface is transmitted through said third surface to indicate the status of the portable computer.
