GoKawiilGuide outlines when closing a laptop lid while docked is safe
A tech advisory piece lays out when it's safe to run a laptop with the lid closed while connected to an external monitor, keyboard and mouse. It recommends fanless or low-power laptops for closed-lid use, warns against doing so with gaming laptops or hot-running workstations, and suggests settings changes in Windows plus using a stand and a docking station to manage heat and cabling.
