Hello, I've recived a HP 15 dead with no power and no LED light on DC Jack. There are no shorts and it don't detect the battery. On BQ24738H, i have this voltages (without battery): 1-ACN 19.5v 2-ACP 19.5v 3-CMSRC 19.5v 4-ACDRV 25v 5-ACOK 2.9v 6-ACDET - 2.65v 7-IOUT 0v 8-SDA 0v 9-SCL 0v 10-ILIM 0v 11-BATDDRV 3.1v 12-SRN 3.1v 13-SRP 3.1v 14-GND 15-LODRV 0 16-REGN 6v 17-BTST 5.8v 18-HIDRV 3v 19-PHASE 3v 20-VCC 19v I think i need IOUT (3v) to start SIO (8987e), right? I already change teh BQ738H for 738 and same reasult, any tip? Thanks |

In the middle pin i have 11.5v (disconected from motherboard). On CN on the board i have: 1 and 2 Red Wires - 19,5v 5 Brown - 0,5v (must be 3v or semething right?) 6 an 7 White and Yellow - 4.95v PS: tested with original charger and switching PSU. |
