Windows Modern Standby bug killed laptop battery and thermals

[LV3i]

In late May, my laptop experienced the Windows Modern Standby bug where the computer hadn't entered the proper sleep. Unfortunately for me, this issue would've normally drained the laptop's battery if it was not charging. However, because I had been charging this laptop overnight, it became extremely hot to touch (I don't know, I guess the CPU was still on, but because the laptop thought it was in a sleep state, the fan stayed turned off). This behaviour killed the battery by causing it to swell and bulge within the metal chassis of the laptop. If I hadn't caught it, the battery could've been punctured and caused a fire within my room.

I'm sure it also damaged the thermal solution, as the laptop runs hotter. I can still use this laptop as I have removed the battery. However, I have been unable to contact HP directly to acquire a new battery. Because of the immense heat experienced my screen has also slightly bowed 🙂

Attached below: side view of laptop, the screen should be flush with the main body but because of a bulge within the main body it does not do that

My warranty also ended in December, 2020 😅 (Doesn't really relate to my question, I don't intend on trying to get a replacement battery, the screen and thermal is already screwed anyways)

This Windows Modern Standby bug seems like it can turn a laptop into a potential fire hazard, how does HP intend to address this dangerous issue?
