I have an hp laptop and bought a brand new charger and battery because the last battery stopped charging, it runs just fine with the ac cable plugged in but if the battery is plugged in it will go randomly from plugged in not charging to actually charging for a few minutes then just randomly saying no ac cable is connected at all, with the new ac cable that I just bought it still says the same issues but it won't even say plugged in with the new or old battery BUT if I turn it off and plug in new ac cable by itself it runs fine, is this a software or a hardware issue? Already have 2 batteries one is brand new and neither will charge with either power supply

The problem is in your hardware. You just check and ensure that the battery terminals on both sides.
Means to say that on battery side & on laptop side. They must be Clean, tightly fitted & no oily substance or lubricant on it.

Both are fine, its weird it will charge when the laptop is off, already tried removing Microsoft acpi controller to see if that works but it keeps reinstalling soon as I restart the computer, it recharged the new battery to full today while it was off and kept switching from charging to plugged in not charging the rest of the day, I have already replaced both battery and charger, and checked all connectors all are still in good shape
