Disassembly, maintenance and upgrade options

Opening the ASUS ExpertBook B1 Hint: Ensure the laptop is powered off and unplugged before beginning.Undo the 4 Phillips-head screws securing the bottom panel. Use a lever tool to pop the rear area behind the hinge cover, starting near the top edges. Lift the top corners and fully pry the back. Continue prying around the sides and front with a thin plastic tool to release the remaining clips.More info: The bottom panel includes a large internal dust filter that helps improve airflow and reduce debris accumulation.Battery Removal Caution: Wear gloves to avoi[...]
