I purchased laptop (Hp pavilion 14-bf172TX) two and half years ago. But 7 or 8 months ago i saw that the laptop battery did not provide exact hours as when i brought this new laptop. I performed the battery diagnose test using hp support assistant and it showed that laptop battery was weak. Now it provides almost 1 hour at 10% brightness. But yesterday suddenly laptop charge stop at 80% and then suddenly started charging and then stop fully. The battery indicator shows it fully charged at 80%. Then i uninstall battery driver from device manager when laptop was plugged in ac and then switch off it and then start it without the ac power. The battery drive automatically install by windows itself. Then i drain the laptop battery at 0% and the again charge it but it now stuck on 35% and the battery indicator shows it fully charged. I don' t know what to do now. Please help me. By the way i performed the hp hardware diagnose for ac adapter and result was passed for adapter.
I followed all your steps but my issue is still persist. I run adapter test with Hp hardware diagnostic software and the result was passed. Then i test the battery using Hp support assitant and it showed that the battery is weak.
