Hello, I have an HP15 laptop. Battery life is decreasing. using HP SUPPORT ASSISTANT I found out I have a dead cell. I ordered a replacement battery and installed it, charged to 100% & tried the battery test again. While the test starts ok after about 30 seconds, my laptop shut down and any test I try, laptop shuts down. I ordered a second replacement battery, different brand, same results.
I am current on all updates and have done a BIOS update. There are no battery drivers to update.
Hi...What are your settings in the CyberPower PowerPanel?I'd suggest performing some more testing too, pull the power from the wall and do a rundown test with different loads (router only, router + PC + monitor, PC + monitor). Do they all exhibit the same results that you're reporting here?
I've seen more UPSes stay on in the event of a low load with no wall power rather than turn off, unless they were configured to do so or had a circuitry or battery cell issue. Those usually exhibit different symptoms as well. I suggest starting with verifying how PowerPanel is configured and load testing via software and manually.
