Battery Low Warning then computer immediately dies

[NeedHelp12345]

My computer just started powering off with no notice.  It used to give me a warning that the battery was "dangerously low" and I could plug it up.  I took it to my computer guys, they ran every test they have and nothing showed up.  I bought a new battery and now I can be in the middle of working a message pops up "battery low" and within 2 seconds it powers off, even while plugged up.  I work from home and really need to know what to do to get this fixed!  Any suggestions?!?

Welcome to the HP Forums, this is a great location to get assistance! I read your post and see that you are getting battery low error and your HP Pavilion 15 notebook turns off. I would like to help you resolve this issue. 

However, I will need a few details to provide an accurate solution,

This happens when it's connected to the wall outlet as well or only when the laptop is running on the battery?

When did this issue start?

Did you do any hardware or software changes?

Meanwhile:

I have a few steps listed below that should help you resolve this concern: 

• Unplug the charge and use the laptop until the battery drains to 15%. 
• Turn off the laptop and turn it back on after 30mins. 
• Reinstalled Microsoft ACPI-Compliant Control Method Battery under device manager, 
• Restart the computer and the issue should be fixed.
