Substantially invisible, tapered, light-transmissive holes are penetrated in a lighttransmissive pattern through at least a portion of the light resistant material using a laser beam having a focal width less than the smallest diameter of the tapered holes. ## Claims ### Claim 1 A laptop computer comprising: a display; a housing base hingedly attached to the display, wherein the housing base comprises: an opaque sheet, a plurality of holes in the opaque sheet, and a transparent structure coupled to the opaque sheet and overlapping each of the holes in the plurality of holes; and at least one light source in the housing base, wherein the at least one light source is configured to emit light through the plurality of holes and the transparent structure. ### Claim 2 (depends on 1) The laptop computer defined in claim 1, wherein the transparent structure is affixed to the opaque sheet. ### Claim 3 (depends on 2) The laptop computer defined in claim 2, wherein the transparent structure is adhered to the opaque sheet using adhesive. ### Claim 4 (depends on 1) The laptop computer defined in claim 1, further comprising a keyboard in the housing base. ### Claim 5 (depends on 3) The laptop computer defined in claim 3, wherein the housing base has an external surface, the keyboard is mounted at the external surface, and the opaque sheet forms at least part of the external surface. ### Claim 6 (depends on 1) The laptop computer defined in claim 1, further comprising: keyboard in the housing base and having a plurality of keys, wherein the plurality of holes are located within a given key from the plurality of keys. ### Claim 7 (depends on 1) The laptop computer defined in claim 1, wherein the transparent structure does not fill the plurality of holes. ### Claim 8 (depends on 1) The laptop computer defined in claim 1, wherein the transparent structure comprises first and second surfaces, the first surface is attached to a planar surface of the opaque sheet, the first surface is interposed between the planar surface and the second surface, and the first and second surfaces extend parallel to the planar surface. ### Claim 9 (depends on 1) The laptop computer defined in claim 1, wherein the transparent structure is configured to structurally reinforce the opaque sheet. ### Claim 10 (depends on 1) The laptop computer defined in claim 1, wherein the opaque sheet comprises metal. ### Claim 11 (depends on 1) The laptop computer defined in claim 1, further comprising a transparent filler in the plurality of holes. ### Claim 12 (depends on 1) The laptop computer defined in claim 1, wherein the transparent structure comprises transparent polymer. ### Claim 13 (depends on 1) The laptop computer defined in claim 1, wherein the plurality of holes each have a diameter that is less than 0.1 mm. ### Claim 14 A laptop computer comprising: a display; a housing base hingedly attached to the display, wherein the housing base comprises: an opaque sheet, a hole in the opaque sheet, and a transparent structure coupled to the opaque sheet and overlapping the hole; and a light receptor in the housing base, wherein the light receptor is configured to receive light through the hole and the transparent structure. ### Claim 15 (depends on 14) The laptop computer defined in claim 14, wherein the light receptor is configured to sense infrared light through the hole and the transparent structure. ### Claim 16 (depends on 14) The laptop computer defined in claim 14, further comprising a keyboard in the housing base, wherein the housing base has an external surface, the keyboard is mounted at the external surface, and the opaque sheet forms at least part of the external surface. ### Claim 17 (depends on 14) The laptop computer defined in claim 14, wherein the transparent structure comprises first and second surfaces, the first surface is attached to a planar surface of the opaque sheet, the first surface is interposed between the planar surface and the second surface, and the first and second surface extend parallel to the planar surface. ### Claim 18 (depends on 14) The laptop computer defined in claim 14, wherein the transparent structure does not fill the hole and is configured to structurally reinforce the opaque sheet. ### Claim 19 A portable computer comprising: a display; a housing coupled to the display by hinges, wherein the housing comprises a housing wall and the housing wall comprises: an opaque layer, a plurality of openings in the opaque layer, and a light-transmissive structural reinforcing element coupled to the opaque layer and overlapping each of the openings in the plurality of openings; and at least one light source in the housing, wherein the at least one light source is configured to emit light through the light-transmissive structural reinforcing element and the plurality of openings. ### Claim 20 (depends on 19) The portable computer defined in claim 19, wherein the light-transmissive structural reinforcing element comprises first and second surfaces, the first surface is attached to a planar surface of the opaque layer, the first surface is interposed between the planar surface and the second surface, and the first and second surface extend parallel to the planar surface.
