In the highest performance configuration, the Surface Book 2 can extract more power than the charger can supply.
With Surface Book 2, Microsoft offers something for everyone thanks to the convertible nature of this 2 in 1 laptop. However, it seems that Surface Book 2 of 15 inches has a Feeding problem that will generate problems if you use the laptop for prolonged and intensive sessions, for example, when playing.
Surface Book 2 uses an Nvidia 1060 GPU that is activated when necessary for more graphics-intensive work. Users can also adjust the Power Mode Slider to "best performance" to make sure they get the most out of the GPU. However, the CPU can extract up to 35 watts and the GPU up to 70 watts of power for a great total power consumption of 105 watts. The laptop is shipped with a 102-watt charger, but only 95 watts reach the device.
Under normal circumstances, when the GPU is only used intermittently, that is not a problem. However, if you are using Surface Book 2 for the game, and it is a very intense game like Destiny 2, the laptop will consume 105 watts of power. Then, even if it is plugged in and charging, the battery will run out.
The Verge confirmed with Microsoft that, in fact, it is possible to drain the battery while it is charging in certain circumstances. Specifically, "in some intense and prolonged gaming scenarios with Power Mode Slider configured as 'better performance'." However, Microsoft explains that "through the design of energy management, the battery will never run out, ensuring that users can continue working, creating or games." In other words, the laptop will automatically dampen performance regardless of the configuration you choose.
Surface Book 2 is a versatile device, not portable for games, but will inevitably be used to play. Most times it will support it, especially if you choose a power mode that is not the best performance. Just keep in mind that playing the latest games in the highest settings will eventually see that the Surface Book 2 literally runs out of power.
If you discover that it is happening repeatedly and there is a strangulation, it is probably time to consider investing in a game. laptop.
