Laptop keyboards are one part of a laptop computer that tends to fail fairly often, but it is easy to see why. The keyboard is one of the components most exposed to liquid damage or other spills, and has to withstand the rigors of human typing all day long. This can make keyboard failures more common than other laptop issues, but luckily, most laptop keyboards are relatively easy to replace. But what are some of the most common symptoms of a defective laptop keyboard?

The most common problem for laptop keyboards is a bad key or keys. In this case, when a user presses the key, it doesn’t register, or only registers intermittently. In most cases, the only way to fix this issue is to replace the laptop keyboard.

A less common problem is that the entire keyboard stops responding. This can be a symptom of a defective keyboard, but can also be caused by a driver issue in the operating system. It can also be caused by a damaged connector cable, or one that has become unplugged. It is a good idea to check the cable to ensure a solid connection before replacing the entire keyboard.

Another problem associated with laptop keyboards are stuck keys, or keys that stick intermittently. In many cases, this can be caused by liquid damage, such as soda pop that has gotten under the keys, causing them to stick. It may be possible to remove individual keys in order to clean out the liquid damage underneath them. Always disconnect the AC adapter and remove the battery before cleaning any part of a laptop, and allow plenty of time for drying before reconnecting power.

Once you have ruled out any software issues and other more simple explanations for your keyboard problems, it may be time to replace the defective keyboard. Find a compatible replacement and a clear set of instructions before attempting it yourself, or take it to a professional repair center.
