big battery and overheating problem

[adjective]

Hi, I'm having a quite big problem with my laptop.

It overheats most of the time, it drains battery like a bomb countdown, and it's not that old! The laptop model is ASUS K571GT, and I bought it in Nov 2019. The problems started about a year or so after I've bought it and I didn't have any clue to why it would be this way. It wasn't a second hand device btw.

Recently I've installed CPUID HWMonitor and interestingly, my cpu cores casually go above 90 degrees on idle! Also, my battery's full charge capacity is stated as 2806 mWh, and the designed capacity is 42032 mWh!(the wear level is also 94%)

Can anyone help me? I can't find any solution or even explanation about this bizarre problem. It isn't an old system and it is bought from a valid store.

(the screenshots are taken at idle, after writing this, which is also done right after starting my laptop)

This is not normal. There's something running on your machine. Possibly a virus, possibly a bitcoin miner, something.

You said the screenshot is from idle, but your CPU then eats 18W package power on idle, which is basically sustained load power limit for a mobile CPU on battery.

For reference, normal laptops should idle around 1-5W with nothing running, with closer to sub 1W usage on an ultrabook or similar. You need to scan your machine for viruses or completely nuke/reinstall windows from scratch.

Your battery wear may be related to this. If you've just assumed this is normal (???) ever since you got this machine (2019), and it's been going through battery cycles as you've described, the wear on that battery pack has probably led to the current 94% wear rate. Batteries wear out over time, based on charge/discharge cycles and heat. With the CPU burning at 100* nearby and constant cycling, it's definitely on it's last legs. Even a year of use like this could have led to the current state, much less from 3.
