I have a Dell g3 3579 with Core I5 8300H and a GeForce GTX 1050 4GB. Approximately two months ago I noticed that the C-states technology, which allows my CPU to go into "sleep mode", made my PC extremely uncomfortable to use.
I'm a programmer who loves to work at night, and I discovered that when this BIOS feature turned on - my PC makes really strange sounds like a matrix printer (Sound sample). This sound really embarras me during my work. And this sound cames only when I work on my laptop with a charger (More precisely, When the CPU core voltage is higher than 1.15 volts). And what's interesting, when I turned off C-states control in BIOS - this sound gone!
Here are my questions for community / Admins:
1. Is this trouble so important?
2. What do i need to do with this sound?
3. How the C-ststes control technology disabling affects baterry life (C-states saves baterry charge)
