i recently got alienware laptop and just noticed it's making screeching noise when i charge the laptop.
Noise is coming from both adapter and plugin cord.
Any ideas? is it harmful? should i replace AC adapter?
makes noise neither laptop is power off and power on.
(but the noise disappears when unplugging it from the laptop, even though AC adapter makes noise itself when plugged in, and the adapter is not getting hot)
