This guide goes over how to remove and replace the keyboard for the HP Envy x360 15m-bq021dx laptop. The keyboard is one of the main ways to interact with a laptop. When it is working properly, keys should press down easily without sticking and should output the letter, symbol, or function that it is designed to output.
Before using this guide understand that the process shown in this guide is a single-use method that once it is completed cannot be undone. This is due to the way the keyboard backing plate is mounted in the case using non-reusable plastic pins. Make sure replacing the keyboard is the only option before continuing with the guide.
Before using this guide check the following possible issues with your keyboard. If the entire keyboard is not working try reinstalling the keyboard drivers. If the keyboard is not working try disabling the intel sensors that check if the laptop is in tablet mode. This can cause the computer to get stuck in tablet mode where the keyboard is disabled. If only the plastic cap on a key is broken while the key can still be pressed and used do not replace the keyboard just replace that keycap. If the keys on the number pad do not work try pressing the number lock key. If a key can't be fully pressed then there might be something under the keycap. Try removing the keycaps and cleaning anything under the keys.
If none of these solutions worked then check the issue with the following list. If only a single key does not work then the whole keyboard needs to be replaced. If just the number pad is not working then the entire keyboard needs to be replaced.
Before starting this repair, be sure to power off the laptop and unplug from the power adapter.

WOW, great instructions. I ran the HP hardware test and confirmed that the keyboard is bad. For forty dollars, I think I'll just buy a Logitech wireless keyboard. Although, your instructions give me the confidence to perform this repair if neccessary. Thank you.
