If you are experiencing issues with your Hewlett Packard (HP) laptop keyboard, such as keys sticking or not working, you may be wondering how to resolve the problem. In this article, we will explore the possible causes of keyboard issues and provide step-by-step solutions to fix unresponsive keyboard keys.
What Causes Mechanical Keyboard Keys to Stop Working?
There are several reasons why mechanical keyboard keys may stop working. It could be due to a bad connection to the computer, a broken switch internally, a stuck switch, debris under the keycap, or poor electrical connections. Identifying the cause of the issue is crucial in determining the appropriate solution.
How Do I Fix Unresponsive Keyboard Keys?
If you are facing unresponsive keyboard keys on your HP laptop, try the following fixes:
Unplug and Replug the Keyboard
Start by unplugging the keyboard from your laptop and then plug it back in. While this may not fix the issue if only one key is not working, it is a quick and easy fix that is worth trying. If the keys start working after reconnecting the keyboard, then the problem is resolved.
Try a Different Cable
If your keyboard is connected via a physical cable, consider swapping it with a different cable and plugging it into a different USB port on your computer. If you are using a Bluetooth keyboard, try connecting it with a cable to see if that resolves the problem. If the keyboard starts working with a different cable, there may be an issue with the original cable or a Bluetooth driver problem.

If you are using a wireless mechanical keyboard that connects over Bluetooth, intermittent connection issues may be due to battery problems. Try inserting a fresh pair of batteries and see if that helps resolve the issue.
Clean the Keyboard
Debris under the keycaps can cause keys to stick or become unresponsive. Start by blowing between the keycaps using canned air. If that does not work, carefully remove the keycaps and blow off the keyboard with canned air. Cleaning the keyboard can help resolve issues with unresponsive keys.
Blow Out the Unresponsive Switch
If a specific key is not working, you can try blowing out the switch. Pry off the keycap of the unresponsive switch, hold the keyboard upside down, and blow out the switch using canned air. If this solution works, it is recommended to clean the entire keyboard to prevent similar problems with other switches.
Use Contact Cleaner
Before attempting this solution, make sure to unplug your keyboard, remove the batteries, and take it to a well-ventilated area. Insert the contact cleaner nozzle or straw into the stem of the key switch and apply one or two squirts of contact cleaner. Work the switch stem up and down and side to side. Allow the contact cleaner to dry thoroughly before replacing the keycap and checking if the key functions properly.
Note: Be cautious when using contact cleaner as it may damage other keycaps. If necessary, remove all keycaps before applying the contact cleaner. Use a contact cleaner specifically designed for this purpose.

If your keyboard has soldered switches, check the solder joints. Broken solder joints on one of the switches can cause keys to stop working. If the solder has popped off the circuit board or the switch contacts appear loose, you can fix the problem by repairing the solder joints.
Replace the Switch
If none of the previous solutions work, replacing the switch is usually the best option. For soldered switches, you will need to desolder and remove the faulty switch, and then solder in a replacement switch. If you have a hot-swappable keyboard, you can easily pop out the defective switch using the appropriate tool and insert a replacement without soldering.
Replace the Keyboard
If replacing the switch does not resolve the issue, there may be a more significant problem with the keyboard itself. At this point, you can either take it to a professional for repair or consider replacing the keyboard entirely.
What to Do if a Specific Key is Not Working?
If only one key, such as the a key, is not working, it is likely a problem with the specific switch or a stuck keycap. Start by removing the keycap and checking for any debris. If you find any, clean it out using canned air. If that does not work, try cleaning the key with canned air or contact cleaner. If none of these solutions work, consider replacing the switch.
