2.6 Ghz I7 is likely the problem. I look through trying to find the specs
on how much power is required to run these kind of laptops and there is no
info. How long can you operate your machine without having the charger
hooked up? If its less than two hours that is not good. You need to find a
laptop that gives you at least 4 hours or more. You don't need a processor
that
cooks along a better than 2 Ghz for what we do with our laptops out in the
field with CCD camera's, telescope mount, guider, 10 programs running at
the same time we are not exactly taxing the machine. When I'm shopping for a
laptop my requirements are how much power does this thing consume less than
65W is good. 45 Watts is better. Clock speeds can be as low as 500 Mhz for
what we do. My 1st Gen I3 machines are running at around 1 Ghz which is
more than enough. Plus I run with the screen dimmed to the min brightness out
in the field and if it sits idle and CCD camera taking picture with guider
running is Idling trust me nothing can be more boring for a computer than
doing this I let the screen go out since I'm likely out running around
looking through other peoples telescopes or bothering Steve Coe. BTW I can get
up to 8 hours on just my laptop battery doing this. The cheaper 200 dollar
AMD machines I find at best buy are about all we need. Now when it comes to
processing images that is a different story but out in the field taking
pictures just about anything works. My 1st laptop I used out in the field
years ago was just 100 mhz pentium machine with less than 500 meg of ram and
that was about typical for the day the hottest CCD was the ST8 and guy's
were taking fantastic images with just this setup. Oh yeah I forgot about this
program I had Astro-Physics Digital Sky voice running the AP 900 goto mount
at that time this was 1998 99 time frame.
