Hi everyone, the laptop charges the battery up to 2 percent and will not go further. The charge IC is BQ738 and I have replaced it with a new one, but still the same. I have checked all MOSFETs around the IC and they all seem to be OK. Here are the voltage readings on the charge IC Pins: 1. ACN - 19V 2. ACP - 19V 3. CMSRC - 19V 4. ACDRV - 24V 5. ACPRES - 3.2V 6. ACDET - 2.6 7. IOUT - 0.3V 8. SDA - 3.2V 9. SCL - 3.2V 10. ILIM - 0.8V 11. BATDRV - 11.3V 12. SRN - 11.3V 13. SRP - 11.3V 14. GND 15. LODRV - 0V 16. REGN - 5.9V 17 BTST - 17.6V 18.HIDRV - 15.1V 19. PHASE - 11.5V 20. VCC - 19V I checked these readings against another model (ENVY 17) using the same IC type and the only difference was PIN15 (LODRV), which was 2.0V. I have checked the LODRV MOSFET on the faulty motherboard and it appears OK. Any help will be appreciated. |

Try another battery. |
