My battery is nearly fully charged (93%) according to the meter.
Why does the meter read full when it will not power the laptop? The battery meter (bottom right on the screen) reads 93% at the moment, it was reading 100% earlier in the week. I would expect a gradual reduction in battery - not a sudden death. I understand they have a finite life but the battery was working for 90 minutes plus last week and now Zero. If you unplug a power adapter and the notebook shuts down, it is usually an indication of a battery which has reached the end of its service life. It is great that you are prepared to help out those that HP abandon. I was hoping that one of them would help me to solve my problem since no one else had replied up to that time. I understand you are not an HP employee but there are some posts on the forum from HP employees. Thank you for taking the time to help with my problem. Your battery needs to be replaced with a new one if it is more than three years old and is not powering the notebook. If that is indeed the case, I can tell you that four to five years is a decent expectation for service life of a notebook battery. It is an HP Pavilion 15-n027sl model from the 2015 model year. I just found the product name of your notebook. I suggest you run those tests and give us the results here in your thread. There is also a battery test that is part of the HP Support Assistant that will allow you to test the battery. There is a components section that is in the HP PC Hardware Diagnostics UEFI utility. Your notebook should have a HP PC Hardware Diagnostics UEFI utility that is accessible immediately after powering on the notebook by tapping the F2 key.
I described how to run a Windows Battery diagnostic in the Notebook knowledge base, If you unplug a power adapter and the notebook shuts down, it is usually an indication of a battery which has reached the end of its service life The forum does not give diagnostics to the best of my knowledge, so what diagnostics have you run? You stated that you ran" two diagnostics given in the forum". You have given some conflicting information and that is why nobody has touched your thread. We are not HP employees, we are customers.
