I recently (~10 d) got such a device to do some number crunching:

**DELL G5 15 5590**

it came with a respectable nvidia GPU, but a Win10 pre-install which didn't bother me.
linux is *not officially supported as shipping OS* for this device, but I thought that it should be no problem, since DELL seems to have shown good will wrt. linux on their hardware in the past.

after recovery image generation, the SDD was wiped and *bionic LTS 18.04.4 installed*. apart from minor problems, this worked quite nicely (apart from some boot hiccup messages, I still have to research for).

**however:** when sending the device to suspend with a full battery recently, and later (+2h) turning it back on, I found the **laptop to have gotten really hot**, fans spinning up like mad, providing a hot flow of air into my hands, while the battery was down to < 10%

it seemed like this would *potentially be hardware-degrading* behavior, if not hazardous.

**Questions:** 

1. how do I best proceed to find out what might have caused this problem?
2. what might cause such an overheating when the machine should be suspended state?
3. am I wrong to ask such a question here?

thanks!
