Microsoft Surface Book 2 13.5 Review
Microsoft Surface Book 2 13.5-inch (2017), the detachable 2-in-1 with a Core i7-8650U, GeForce GTX 1050, 8GB RAM, 256GB SSD and a 13.5-inch 3000x2000 IPS touchscreen.
The Surface Book 2 has two batteries: an 18Wh G3HTA044H in the screen (tablet) half and a 57.3Wh G3HTA049H in the keyboard base (1835). The 75.3Wh total here is the sum of those two iFixit figures. The screen is a fused display assembly, so we do not list a separate panel part.
