Notebook didn't charge in full and didn't hold a charge so I ran a battery test which resulted in windows recommendation to replace the battery so I did and purchased one on eBay.
These are sequences I experienced post-replacement:
-> laptop on, adapter plugged in, windows showing 100% charged - unplug ... 1% within seconds .. then it will turn off
-> same thing, laptop on, adapter plugged in, 100% charged - unplug .. dropped to 1% .. quickly connect to adapter... it will start charging, three minutes later it'll show fully charged.
-> first troubleshooting showed a weak capacity
-> later HP Hardware diagnostic showed battery check cancelled
-> NOW this is important! I ran a memory test in Bios, the laptop was unplugged from adapter the whole ten minutes and hold it there until the finish. When it booted to Win, it immediately showed 1% again.

As you tried with new battery and the problem still persists, some other possible solutions includes :
1. Check for any damages in the power cable.
2. Try charging with other compatible charger if available.
3. Update you drivers.
Open the Start menu and search for "Device Manager."
Under "Batteries" you should see a few items: usually one for the charger and one listed as "Microsoft ACPI Compliant Control Method Battery," though there may be others.
Right-click each item and choose "Update Driver."
Then reboot the laptop and plug-in again.
4. You can also check for any latest drivers from HP website.
5. If these doesn't work, the cause may be because of the inside problems.
Common inside problems may be one of these : a faulty motherboard, damaged charging circuits, and malfunctioning battery sensors.
In this case, its better to visit nearest HP service center.
