The new Surface Pen has a secret button just under the end of the plastic strip.Īlthough Microsoft stores we’ve spoken with say Surface Pro 4 will not work with the older Surface Pro 3 dock, we’ve been told by Microsoft it will. At the very end of the plastic strip just above where your finger would rest when using it, however, there’s a hidden button that acts as right mouse click. The Surface Pen doesn’t look like it has any buttons besides the “eraser” at the top. You can indeed remove the AAAA battery from the new Surface Pen by rotating it slightly counter-clockwise until it clicks. You should be able to carefully slide out the AAAA cell now. To pop it open to change out the AAAA battery, grasp the shaft and then turn the end with the pocket clip on it counter-clockwise about an eighth of an inch until it clicks. The pen on the Surface Pro 3 and Surface 3 easily unscrewed but the newer Surface pen isn’t quite as straight forward. A free app from Microsoft will let you change the pressure levels of the Surface Pen.
