The Motherboard Replacement Guide provides the steps required to replace the HP Chromebook 11-v019wm Motherboard. The motherboard is the brain of the computer and has an extensive list of functions. The motherboard should only be replaced after all other troubleshooting steps have been exhausted. Basic reasons to replace the motherboard on the HP Chromebook are to replace the RAM on a lagging Chromebook, if the computer fails to turn on even after replacing the battery, basic computer functions have been lost, etc.
It is important to note that replacing the motherboard will also delete the motherboard and operating system. This may require a boot disc for the Chrome Operating System and a system back up to protect important documents.
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.
