For mobile I use either Dell XPS13 or MacBook Air with Win 7 installed. 
Both have good batteries (Mac is better though) and give me almost 8 
hours of operation with N1MM+. Then I make a break and charge batteries 
for the next session. Both are pretty RF quiet because both have 
Aluminum body.
There are laptops with 13V supply but the choice is very limited.

 Make sure you put torrid's on all the cabling from the computer to the

and the antenna is less than 5 feet away.

This is about contesting...  mobile contesting
The laptop I use for mobile is nearing its end after about 10 years
of general use  and mobile. Now just mobile as I didn't care about
OS  (it's WIN8) as long as it ran N1MM+. But it has become
unreliable even after full factory resets.
My main laptop, a high powered workstation is great, but not so good for
 mobile. It doesn't have a mobile supply for vehicle use and while I 
have tried
quiet inverters, the real noise from battery charging seems to be 
internal  to
the laptop.
 It would be good to find a reliable laptop that can run off vehicle 
power (even with a dedicated
accessory supply). It doesn't need to be a workhorse and cheaper 
would be great. It just
needs to run N1MM+ and not generate  RF on it's own. Unfortunately, 
cheaper may mean less
RF suppression and susceptibility. I'd appreciate comments from folks 
who actually run laptops mobile.
(I can look at specs all day on the web but that  doesn't tell you 
much until you turn it on in
a vehicle.)
