W83L784R/ W83L784G
2.2 Actions Enabling
• Issue fan fault signal as fans are abnomally stopped
• Issue battery low signal as bettery voltage is abnomally out of range
• 2 PWM (pulse width modulation) outputs for fan speed control to support S Thermal Cruise^TM T or
S Speed Cruise^TM T
--- Automatically maintain the CPU or system in the specific temperature or keep the fans in the
specific speed under the H/W control
• Issue SMI#, OVT#, GPO to activate system protection
• PWR_DN# setting for the Power down mode
• Warning signal pop-up in application software
2.3 Power Good
