Gaming Notebooks

I recently received my HP OMEN 17t-an100 CTO back from the HP/Quanta service center. I made note of the failure ID for the battery to the OMEN Team support over the phone, and made note of it on the service paper, however the service center did not replace the battery for an unknown reason. Upon using the laptop again a very sudden issue has appeared..... somehow Windows believes that the battery.... is gone..... and also at 255% at the very same time.

Battery "mouse-over" notification, reading 255%. Either that's just "FF"in HEX, or this laptop really isn't powered by a battery at all, but regenerative nuclear fission.

No battery is present, yet it's a non-removable battery. Hmmm... The battery can't just run away now can it?

However, this all occurs intermittently and I am not sure what is causing this to occur. Also, unplugging the power adapter yields no differing result. (I guess this laptop is powered by something other than a battery right?)

I am unsure of what is causing this as the HP PC Hardware Diagnostic for Windows reads "Logic state: OK. Charge state: NOT AVAILABLE." however under the detailed information, the line "Primary_ChargeControl: Failed" raises a little suspicion to me, however I do not know what it means.

HP Support Assistant says the battery is at 0% and also, non-existent.

Not even HP Support Assistant can help us now. We're doomed.

I have all my drivers updated, and this issue has/is persisting in both the Windows 10 1809, and Windows 10 1903 update. 

Any ideas?

(lastly, a bonus screenshot of HWiNFO64 not reading the battery either,  but a very odd abnormal maximum recorded remaining capacity a few moments before the battery disappears. Table has been marked by me, for convince.) Astonishingly the battery had read a whopping 315.18Wh before the battery had vanished. Values are greyed as HWiNFO is unable to obtain any updated information about the battery and its capacity, and voltage status.
