laptop battery

[Andy Boersma]

Most laptops will run without a battery, but some of the newer Intel designed/build motherboards in them the CPU is cycled down.

We did some test on a 2011 MacBookPro and a 2014 Dell Precision Laptop, both CPUs slowed 40%
A Dell Latitude just continued at the same speed.
