I would try and see if there is anything about this on Acer's forums but, I was experiencing this on my Dell XPS. I avoided it by typing and using the touchpad while plugging it into the AC adapter.
Hey there, we are going to need a bit more information. What devices are you plugging into? And are you trying to get an Ethernet connection working? Last, are you up to date on your MAC/Windows updates?
I recently just picked up a klipsche promedia system for my computer set up. My parents had a similar version by energy and it sounded great so I thought I was going to get the same.
My question is, would it be worth just replacing the 3 " woofers and the 6.5" woofer with some Dayton Audio...
