: 4 x USB 2.0 ports, 1 x RJ-45 Ethernet (Realtek RTL8103EL), 1 x VGA, and 3-port audio jacks. The , widely known by its HP codename

: The Rev 1.1 board had a subtle change in the +5VSB (Standby) circuit. The verified schematic showed a decoupling capacitor, C142, that wasn't present in the earlier designs. Elias looked at his board; the cap was there, but its casing was slightly discolored—a microscopic crack only visible under the jeweler’s loupe.
