Compatibility Is Key
First and foremost, I made sure the keyboard was specifically designed for the HP ProBook 645 G4 model. Even slight variations in laptop models can mean different keyboard connectors or layouts. Checking the model number and confirming compatibility saved me a lot of hassle.
Keyboard Layout and Language
I paid attention to the keyboard layout—whether it’s QWERTY, AZERTY, or another format—and the language settings. Since I type mostly in English, I looked for a US English keyboard layout.

Installation Process
Since I planned to install the keyboard myself, I checked whether the keyboard came with installation instructions or if there were tutorials online. The HP ProBook 645 G4 keyboard replacement is relatively straightforward, but having the right tools and guidance made the process smoother for me.
