3. USB device wake-up (3-pin USBPW1-4, 3-pin USBPW5-8) Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected USB devices. Set to +5VSB to wake up from S3 and S4 sleep modes (no power to CPU, DRAM in slow refresh, power supply in reduced power mode). • The USB device wake-up feature requires a power supply that can provide 500mA on the +5VSB lead for each USB port; otherwise, the system would not power up. • The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode. 4. HDSW setting (30-pin HDSW) This jumper allows you to switch between the HDMI and the DVI features. By default, the HDMI feature is enabled. To enable the DVI feature, set this jumber to pins 2-3. To switch to HDMI, set this jumper to pins 1-2. ASUS M4A78-VM IN/SI 1-8
