Razer Blade hardware - extreme battery swell, loud noise, trackpad

Hi,

I bought my Blade about 2 years ago, and for the past 10 months, the bottom has been swollen.
I think the issue is the battery expanding, which has warped the metal frame, the bottom of my laptop has had a very convex swell, which I've attached some photos of.

I thought I'd just continue using it as is, my laptop still works alright, but recently heard that battery swell can lead to explosion if the battery gets punctured, and catching fire unexpectedly, and that really frightens me. I'd like to get this repaired as soon as possible.

I've checked my Limited Warranty using my Serial Number, and I am out of warranty.
I still want to get support, and I'd argue that most of the cost of repair should be subsidized. I did some googling to see what caused this, the danger, and the typical size of the bulge, and this seems beyond extreme - all online info was urging replacing a battery with a bulge a quarter the size of mine. One photo below includes a Loonie (coin) for scale, and you can see the bulge is very massive.

Other issues that I'm sure are related:

• Noise: my fans worked pretty well before, but now since the whole laptop is warping, they are noticeably louder than they were.
• Extreme noise: there's times where my laptop makes very loud and jarring noises. It sounds like an airplane is taking off, with bursts of loud motor whirs and deep "chunk" sounds. The sounds are hard to describe, but these sounds are incredibly alarming, and it makes my laptop embarrassing to use in public. When this happens, I've tried doing a full shut down/ restart, and the problem persists. The thing is, this only happens once in a while. I've gone for weeks with it working quietly as intended, and then it can start whirring loudly, and won't stop for multiple days, through power-offs.
• Trackpad: in one of the photos, the trackpad can be seen as protruding from the upper edge, it doesn't lie flat. It's less responsive this way, so I've tried pressing it down into place, but this then causes the cursor to move all over the entire screen unpredictably. clicking like a hundred times a second. When this happens, I fully lose control of my laptop, even my external mouse cannot control the cursor, and my only option is to shut it down by holding down the power button for a few seconds.
