FAQ

Q: Why does my Surface Book turn off when I detach the screen? A: This is typically due to a failed G3HTA020H screen battery. While the base battery provides bulk power, the screen requires its own internal battery to function in tablet mode. Q: Is installation difficult? A: Replacing the Surface Book screen battery involves heating and carefully removing the bonded display glass; we recommend professional assistance or using a specialized repair toolkit to ensure a safe replacement.
