A Dell 3140 laptop. With HA and a number of other apps it loafs along at about 5% CPU. When Frigate is enabled it jumps up to 14% or so while drawing between 6 and 12 watts. The battery prevents power blinks in our area from being a problem, unlike my Pi4 that crashed and didn’t recover when I was hundreds of miles away. The battery lasts hours when the power fails and the keyboard and display are convenient.

For those concerned about the battery, it’s firmware limited to a 70% charge so it will last years. Current Li-Ion batteries have about a 1 in a million chance of fire. A car parked in your garage is hundreds of times more of a risk.

It’s been excellent and I’d buy it again.
