power use
I bought this particular laptop because it had "advertised" great battery time: about 2.5 hours but i suspect that that is not entirely true unless you run in a miniature size display which is not appropriate for astrophotography.
maybe i should just bite the bullet and but a petrol inverter, eg a 1kW honda or something, i am scared that i will kill the battery by discharging and recharging incorrectly.
Are they quiet enough??
