Eliminating Installation Roadblocks
The primary concern for any professional sourcing their own parts is the “mechanical mismatch”, the fear that a ribbon cable might be slightly too short or a mounting pin slightly off-centre. We address this by offering a 7-day return specifically for compatibility issues. If the unit does not seat perfectly into your EliteBook chassis, we provide a streamlined exchange process (subject to policy).
The Advantage of Verification
While the technical lists provided are accurate for the majority of G1 and G2 models, HP occasionally utilized different manufacturer revisions during production. Clicking our “verify Compatibility” button allows you to verify your specific revision with our technicians. This 60-second step is the best way to ensure that when your package arrives, your laptop is back in service within minutes, rather than days.
Maintenance & Setup Guide
Is this keyboard compatible with my backlit model?
Yes, you can install this non-backlit unit into a laptop that originally came with a backlit keyboard. It will function perfectly for all typing and navigation.
What tools are needed for installation?
The EliteBook 840 G1 is user-serviceable. You will typically only need a small Phillips head screwdriver and a plastic prying tool to release the keyboard from the top cover. No soldering or permanent modifications are required. If you are uncomfortable performing the installation, a professional technician is recommended.
How do I clean the pointing stick?
The rubber cap on the pointing stick can be gently removed for cleaning with a damp microfiber cloth. This allows you to maintain a high-grip surface without needing to replace the entire keyboard assembly.
