Re: Laptop hum recommendations

Sure. That's what I've been doing.

However, Dulls (and probably most laptops) don't run for more than an hour
running CPU intensive applications (such as any kind of audio DSP) on a
fully charged battery. The batteries aren't cheap, either.

I have enough to think about on stage without playing count down with my 
pc.
You are also going to have quite some fun re-charging a battery while you
play (I'm not sure of how you would do this, without using a second laptop 
-
I've looked for chargers), so for a one hour gig, you will need at least
three, if you intend to bring a backup.

My work's IT department says that the batteries don't last for more than a
year, either - they are constantly replacing them, as a matter of course.
(Perhaps yours will last longer - my laptop is on 10 hours+ each day) Make
sure they are covered by your warranty.

This all brings up another of the dull short comings - switching the
batteries while on wall power can crash them. Again, customer support says
there is no fix.
