Overview
An Asus K53E came in from Wandsworth with keyboard faults that made routine work difficult.
Symptoms
- Several keys not registering
- Intermittent character repeats
- Reduced usability for email and document work
Diagnosis
External software checks were clean, and the fault pattern matched physical keyboard matrix failure rather than an operating system issue.
Fix

Result
The laptop was returned with consistent typing performance and no further key dropouts.
Prevention / Tips
Keep liquids away from the keyboard and clean debris regularly to extend keyboard lifespan.
