Laptop temperature shoot when plugged in

[alfac95]

Laptop specs:
i5 8300H, 16 gb ddr4 ram, ssd + hdd, onboard Intel uhd 630/ gtx 1060 dedicated gpu

Since a couple of days, my laptop temperatures instantly go up by 20-25C on idle as soon as the charger is plugged in. There's literally no load or processing going on, being around 40C at idle on battery power, and going immediately upto 60-65-70C as soon as the charger is plugged in. I tried adjusting my power plans, I tried almost anything that should have rectified this issue, but to no avail. There's one thing which is confusing, that the temperature falls back to normal even when plugged in if I turn off the wifi. What could be the possible reason and fix to this?

What did you try so far?

Make and model/SKU of your laptop? Are you on the latest BIOS update for your laptop? As a last resort you should try and backup critical content and then reinstall OS after you've recreated it using Windows Media Creation Tools.

Cryptominer infection perhaps?
As soon as internet is connected, it starts cryptomining and rises system temperature.

It's an Acer Predator helios 300, and yes my BIOS is up to date. I tried cleaning the dust off by dissembling the unit, I tried resetting my GPU performance settings (Although they were never messed with in the first place), I reset the power plan / power options (Which weren't messed with apart from increasing the screen timeout duration), did virus scans. So far nothing has seemed to do the thing

I'm way too naive regarding cryptomining. Being said that, I have never done that myself if that's what you mean. But if I've got some sort of malware or cryptomining infection while downloading something, then it might be a possibility. It doesn't affect my temperatures when I'm on battery at all, no matter if it's idle or under load. The problem occurs when I'm plugged in + connected to wifi (No temperature rise if the wifi is off). If it was a malware, I guess it should have affected the temperatures while on battery too isn't it?

Not necessary. It depends on, how smart the malware is.
Just check cpu usage and gpu usage, when you experience increased temperatures.

That's another catch which is weird, the CPU usage stays near to nil, unaffected and the dedicated GPU states itself as idle when this temperature boost happens..I checked it in the task manager as well as the predator sense charts, there's no process that I can find or point out to be using any resources..should I drain my battery once if that's gonna help?
