Hi everyone, I was working on a toshiba L745 DATE5MB16AO when PQ3 and PU10 got shorted and the KBC died. After Changing KBC [new one] and checking to make sure all pins are soldered firmly, and changing PU10 and PQ3, the laptop does not power on. I have +3VPCU and +5VPCU on the coils PL4 and PL5 respectively and 3.4v [NBSWON#] on power switch and +3VPCU on KBC SPI [U13]. I do not have +3V on BIOS SPI [U6]. There is no standby light and the battery does not charge. When I insert a charged battery and press power switch, the power led lights up for 2 seconds and goes off, but with adaptor only inserted, nothing happens. I have changed the charge IC [PU1] but still nothing. I have also changed PQ14 [no MAIND voltage on pin3]. I need help on what to check next to get +3V up and running. thanks in advance.
