Laptop keyboard failure is always of two types: software or hardware. Software problem issues related to laptop keyboards are very few.

Laptop keyboard hardware issues

The hardware issues are the most frequent for keyboards and those can be classified to:
1. Laptop keyboard connection problems. Every laptop keyboard has a thin ribbon cable which connects the keyboard to the main board. If this connector is loosened, the whole keyboard won’t work. If just few keys are not working – it usually is another problem.
2. Broken laptop keys.
3. The spill of any kind of liquid. If you happened to spill some water or any liquid which does not contain much sugar or other “minerals” – you’re lucky. Lucky, if you spilled it the keyboard, not the whole computer. As most keyboards have some kind of base – it usually stops the liquids from touching the more delicate parts, like motherboard, hard drive or processor. Water or spirits will evaporate leaving nothing between the keyboard keys.
However if is happens to be Coca-Cola, coffee, tea or anything else besides water – the keyboard repair could take longer and in most cases it’s less costly (regarding time and money) to replace the whole keyboard at once.
