1. Determine the keyboard is faulty. Find a desktop keyboard with a USB connection and plug it into your laptop. If it does not work right away, then restart your laptop. Try typing on the desktop keyboard. If that keyboard works, then the problem isn't your motherboard or software. Instead, you will have to replace the keyboard.
2. Determine what model number you laptop is. The number is usually found on the manufacturer's sticker on the bottom. Search for a replacement keyboard that is specific to your laptop's model. Parts are found either on the laptop manufacturer's website, or on online stores such as Amazon. EBay sellers also list new or used laptop parts.
3. Find a parts or service manual that will tell you how to fix and repair your specific laptop. Otherwise, determine if your laptop's keyboard has any screws holding it in from the bottom of the laptop case. Check around the keyboard for clips and push them back if any exist. If there are no clips, and removing screws from the laptop's bottom does not cause the keyboard to come loose, then remove the plastic bezel pieces that surround the keyboard, starting with the one at the top. Find screws anchoring the keyboard inside and remove them.
4. Lift the keyboard up slowly. Look for where it is connected to the motherboard and gently disconnect the cable. Set the keyboard aside. Take out your new keyboard and connect it to the motherboard. If there is no connector end on the keyboard's cable, then gently pull the connector on the motherboard upward to open it and slide the cable in. Close the connector back over the cable. If the keyboard does have a connector at the end of its cable, then simply connect it to the motherboard's connector.
5. Position the laptop keyboard and then replace all screws and bezel pieces. Lock the clips back in if there are any. Power the laptop on, making sure the external keyboard is no longer plugged in, and test that the keyboard works. Check the keyboard cable connection if the keyboard still does not work.
