Case is distorted and bulging besides touchpad

[Deefae]

I was directed here and I sure hope someone can help me with a laptop thats starting to deform before our eyes.

I bought this laptop in 2019: a HP Envy x360 -15, for CAD use at uni I had just been accepted to, only to then end up in a pretty horrific situation and unable to attend.

Now disabled and thoroughly miserable - I put the laptop aside and it has basically seen no use for a large chunk of that time.

Recently, its been used by my gf for her uni work instead - but again, its of limited use as she can only study part time in order to look after me.

Today we noticed that the screen wont shut flat like it once did.  Examining closer you can see the part of the laptop that holds the touchpad is now bulging up (slightly left of the touchpad, id say... in front of the keyboard)

There is even a gap around the touchpad now thats never been there before.

The most its been used is since Oct last year and thats been for facebook nonsense, zoom calls and open office for assignments. Nothing overly taxing for a system I was assured could handle the CAD requirements I needed of it.

It runs windows 10 home - 64 bit

Product number: 4A26PA

A quick google and I noticed some mention about a recall on batteries in some HP systems, but it does not seem to include this system. 

Downloading the app to check the battery says that it is "fine".

To be honest, this has done little to reassure me and I am anxious to use the laptop ever again - apart from that my gf has come to rely on it for her assignments and if nothing else, needs to get her work off the system.

Is this something of concern?  Especially due to its relative inactivity until recently?

Is it safe to use?  Can something be done about this, or is it likely to get worse?

Any help would be greatly appreciated and welcomed wholeheartedly.

It is likely the tablet battery has inflated and is putting pressure on the surrounding components inside the case.

The battery must be removed from the computer and replaced.

"Fat" Battery / Bloated Battery / Swollen Battery – Sealed / Internal Battery

• Swollen battery might be hiding OR there might be evidence that the battery has inflated.  For example, notebook case is warped, touchpad stops working, “odd” bulging near the keyboard.

• If the battery is in a swollen or bloated condition, the battery must be removed from the computer and replaced.  There are no other remedies, tests, or useful options.

In spite of the battery check, the battery will fail and might further inflate.
