Hi everyone I have a problem with this laptop that won't turn on. The +VCORE is not present and doing some measurements on the ISL95859 I notice this: VIN present 19.5V VCC present 5V VR_ENABLE present 3.3V PWM_A present 2.5V FCCM_A not present PWM1_B present 2.5V PWM2_B present 2.5V FCCM_B not present PWM_C present 0.32V FCCM_C present 5V In these conditions should the ISL95859 works and therefore enable the FCCM_A and FCCM_B pins or do I have to check other lines for it to be enabled? Maybe the ISL95859 is dead? I add the very very similar schematic Thank you |
