A:Answer This laptop has the "U" designation on the CPU, which stands for "ultra low power". The CPU typically draws 10 watts or less, according to my monitoring software, and the total system power averages around 12 or 13 watts most of the time.
I don't like fan noise. This system has a "Quite Mode" option, which I use all the time, and I set the processor management to keep the CPU at 75% power. With these settings, the system is still 10x as fast as my previous computer, and the fan rarely comes on, and when it does it comes on quietly. It does not get hot under normal use.
The CPU is capable of hitting 45 watts for brief periods, and it could get hot and produce some irritating fan noise if you maxed out the performance a lot.
I don't have empirical data on the battery, as I typically keep it plugged in, but it will last several hours. Also, it charges through the USB-C port, so you can recharge it from a portable power bank.
