Solved Battery plugged in, not charging. Random shut downs...etc

Specs: Windows 10, 8GB
For the last few days, I've been having issues with my notebook's battery (at least I hope that's all it is).

For one, I'm not sure it is charging correctly because when the AC adapter is plugged in it says 'Plugged in, not charging' and the percentage never exceeds 93-96%.

When I'm running on battery power it seems to run down very quickly and the notebook shuts itself off at random. The other night, it said it had 48% battery life left, then a minute later it shut down without warning.

I have also noticed the battery seems to be affecting performance;

When both the battery and the ac adaptor are plugged in, my notebook is sluggish; it is slow to start up, slow in general.

When the battery is removed and just the ac adaptor is plugged in, everything is a lot faster.

---

The battery is just over a year old.
I ran HP's Battery Check and it said the battery was OK.
I also tested the battery, and performed a full system check, using the HP Diagnostics UEFI and everything passed.

I've ordered a new battery in the meantime I was wondering if there was anything else I should be checking for just in case this isn't solely an issue with the battery.

Thanks for your time.

Testing the system with the battery removed is what I would have recommended but you have done this. It appears to indicate that the battery is bad but the possibility that the battery charging circuit in the laptop is still possibly the issue here. The sluggish performance with the battery installed and not without it, does sound like a bad, shorted, or reverse polarity in one of the battery's cells in this case. Since you have already ordered a replacement battery, the next test is with the new battery but treat it as with a new machine and let it charge overnight with the machine off. I do not know if the charging circuit is part of the motherboard or on a separate board but a look at the service manual and parts list should give you an idea. Good luck for now and let us know how the next step goes and check back for other opinions as well.

You have to be a little bit crazy to keep you from going insane.

Is this a genuine (replacement) battery from the manufacture? or one you bought from one of the "battery (online) shops" claiming to be the "right" battery for your laptop?
