Here at DGADGET we understand that it is frustrating when one or more of the keys on your laptop keyboard do not respond when you are typing. However, there are simple fixes you can try to get the keyboard back up and working.
Dirt, Dust and Spillages
To keep your keyboard in pristine condition, you should give it a clean every so often with a keyboard vacuum or use a can of compressed air to spray in-between the keys so that all the debris is removed.
If you spill liquid onto your laptop keyboard, it can cause the keys to go sticky and cause other problems with the laptop. When liquid is spilled onto the laptop, you should immediately unplug the laptop and remove the battery (if this is sealed in then you should shut down the laptop) to prevent any electrical damage, if not caused already. If the spillage is quite small, then using a cloth to remove the excess should get it all. But if the spillage is big, then tilting the laptop towards the air vent and lightly shaking it should help remove more liquid this way.
If the laptop keyboard has suffered a lot of damage, then it is best to have it repaired or replaced.
Restart your laptop
Restarting your computer may resolve the issue with the keys not working on the keyboard. If you cannot use the trackpad on your laptop to restart it, then hold down the power button for a few seconds to shut it down and once the laptop has switched off, press the power button again to start it up again.
Keyboard Driver Issue
The issue with the keyboard could be down to a driver issue because of a third party program that has been installed on the machine. To see if there is an issue with the keyboard, go to the Device Manager on the operating system, then find your keyboard in the list of devices. If there is a yellow exclamation mark next to it, then you will need to update the drivers for the keyboard. If you cannot do this, you might need to plug in a USB powered keyboard in order to do this.
Use a USB keyboard
If you quickly need to use your keyboard, you can use a USB powered keyboard until you get the chance to fix the issue with the onboard keyboard.
You may have a defective keyboard, if you have tried to fix the issue and it has not worked then it is best to contact the manufacturer or the retailer from where you have bought it to check to see if it falls under the warranty period for you to get it fixed or replaced. Always back up your data before sending your laptop in for a repair.
If you regularly clean your laptop keyboard, it stops the keys from getting sticky and any dirt building up. We hope these solutions above will help resolve any problems you are having with your laptop keyboard.
