Battery Shuts off without warning and HP Hardware Diagnostics will not open

[NJacobs]

My laptop has consistently shutoff without warning at around 50% battery power when not plugged into a power source. Also, the HP Hardware Diagnostics will not open (run as administrator) for me to run a battery test. I have already repaired, restarted, and even reinstalled the Diagnostics application so that step has already been attempted with no success.

I tried that with no success as the laptop still turned off abruptly.
