Introduction

The hinge assembly is a purely mechanical part responsible for regulating the movement between the upper and lower case. Over time, or with physical damage such as a fall, the hinge assembly may fail or start to loosen, preventing the laptop from being held in an open position when desired. If this is the case, the following guide will help one to replace the assembly and resume the desired movement from their device.

The hinge of the One Education Infinity facilitates a 360º range of motion such that the laptop can be used in a tablet mode, with the upper case of the device swinging below the keyboard.

Additionally, note that this guide has the user remove the battery prior to disassembling the upper case to prevent any electrical damage while disconnecting the display cables. However, the same effect can be achieved by simply disconnecting the battery cable, so the battery removal in step 5 can be skipped to save a bit of time and effort.

  • Remove the screw covers and rubber feet from the bottom of the laptop with a metal spudger.
