When troubleshooting a motherboard using the IT8995E-128, engineers focus on several critical signal pins: Description 3.3V3.3 cap V Standby power rail required for the IC to boot. WRST# / EC_RST# Hardware reset signal; must be high ( 3.3V3.3 cap V ) for operation. NBSWON# / PWR_SW# Power button trigger input; drops to when pressed. DNBSWON# : The EC asserts RSMRST# to tell the
