Intel® 945GME Express Chipset—Hardware Reference

4.4Power On and Reset Buttons

The Intel® 945GME Express Chipset board has two push buttons, POWER and RESET. The POWER button releases power to the entire board, causing the board to boot. The RESET button will force all systems to warm reset. The two buttons are located near the CPU close to the edge of the board. The POWER button is located at SW1C2 and the RESET button is located at SW1C1.

Note: If the board is powered from an external ATX power supply (not a power brick), the Power button must be pressed twice to turn on the system.
