The Touch Display Replacement Guide provides the steps required to remove the HP Chromebook’s Touch Display. The touch display may need to be replaced if the display no longer responds to the user’s touch, the screen won’t illuminate with the power on, or the screen becomes broken or cracked. Prior to replacing the touch display, ensure all of the troubleshooting steps have been completed in accordance with the Troubleshooting Guide. If the display must be replaced, the complete touch display assembly has to be replaced due to the touch functions.
Removing the keyboard will expose the internal components of the computer. These components are electrostatic discharge (ESD) sensitive components. It is important to ensure that an anti-static wrist strap and anti-static mat are used to prevent ESD from damaging other components inside of the device. For proper use of the anti-static wrist strap, refer to iFixit’s “How to set up your Anti-static mat and wristband” Guide.
