Issues with my Dell XPS 15 9570

I have 3 issues with my Dell XPS 15 9570.

1. The speakers of my laptop start firing noisy audio outputs after using them for about an hour or two. The problem is not of hardware because the same issue is faced when using an earphone or headphone with them.

2. The display of the laptop automatically adjusts its brightness with different applications which I don't like. I should be able to set the overall brightness and not the device itself as I find this troublesome while using it with my designing software. 

3. The laptop generates a lot of heat even when its in sleep mode. There might be no apps running but still, every time I try to resume it from the sleep mode, it is burning with heat.

I have updated all my software and drivers several times but it doesn't help.

Please suggest or guide me.

Thank You.

1. DPC Latency issue, supposedly fixed with BIOS update.

2. You may have to turn off Adaptive brightness, either in windows or BIOS settings.  https://www.dell.com/support/article/us/en/04/sln287324/disable-adaptive-brightness-to-correct-dim-s...

3. Known issue, they are working on a fix.




If you just bought it and can return it, do so. This model is plagued with issues. We just started replacing these models in our fleets with HP EliteBook 850 G5's.
