I have a very powerful gaming laptop
that I use at home for....gaming. I've been messing around with OpenCPN
and would like to use it on my boat, but my laptop
is very power hungry. I've been considering buying
a low end netbook to use for navigation
, but before I drop money
on that as a single
purpose tool, I'd like to know if turning my settings down on my current
laptop will reduce the power draw from the power supply.
I've been trying to find information on how laptops use energy when plugged in, but it's hard to separate this particular topics from things like "should I leave my laptop plugged in all the time" nonsense. So hopefully someone who uses laptops regularly on house batteries can fill me in.
Will the laptop's power supply unit always draw maximum amps, regardless of what the laptop is asking for? Or does the power supply adjust draw based on what the laptop is asking for? If I leave the laptop plugged in while I'm using it, will it just pull a trickle from the battery
, or use the full amp rating on the power supply the entire time?
