Keyboard fault diagnosis
A few unresponsive keys can result from physical wear, contamination, liquid exposure, a damaged ribbon cable, software settings or a motherboard input fault. Testing helps avoid replacing the keyboard when the underlying problem is elsewhere.
Common keyboard symptoms
- Individual keys or complete rows not responding
- Keys typing twice, sticking or producing the wrong character
- Broken keycaps, hinges or missing keys
- Keyboard backlight not working
- Keyboard failure after liquid exposure
Integrated and separate keyboards
Some laptops use a replaceable keyboard module, while others integrate the keyboard into the palm-rest assembly. The correct repair route depends on the construction, layout, colour, backlight option and exact model. We confirm the compatible part and whether the top cover must be replaced before work begins.
Post-repair checks
We test key response, function keys, backlighting where fitted, touchpad operation and the physical fit of the palm rest. Liquid-damaged machines may require additional board inspection before a keyboard warranty can be confirmed.
Final cost and turnaround depend on the exact model, fault and parts availability. We confirm the available route before beginning the repair.
