Notebook Software and How To Questions

Hello Everyone,

I have a "HP Pavilion 15 Notebook PC" with Windows 8.1 and is almost two years old.  A few months ago I had my laptop on my lap and it randomly turned off, after turning it back on it did not charge above around 84%.  Every now and then I would plug it in to charge and it would say "plugged in, not charging" so I fixed the issue by turning it off, taking the battery out, turning it on, uninstalling  Microsoft ACPI-Control Compliant Method Battery, turning it off, putting the battery in, turning it back on, and the ACPI-CCMB would update and it charged back up to around 84%.

As of about a week ago, that stopped working. I've tried updating the ACPI-CCMB, doing the above multiple times, and nothing works. I noticed the recommendation for the HP battery utility but 1) that didn't work in the past when it wouldn't fully charge and 2) the computer has a 0 percent charge and will not hold a charge, so in the step where it says to turn it on unplugged, my computer won't turn on.

After trying to use the HP battery utility a few things happened. 1) I have to mash the escape button in order to access the menu, pressing it when the logo appears like it says does nothing. 2) When I tried to run the battery test, it said 2 minutes remaining and 1% complete before freezing the computer up and after pressing the power button it instantly turned off.

I don't know if I need to get a new battery or if I just need to try something I haven't heard of yet.

Thanks for your help.
