First check the software problems, then consider hardware repairs or alternatives. Confirm whether it is a system or driver abnormality, check the system update and keyboard layout through external keyboard and screen keyboard test; if it is physically damaged, try replacing the keycap or looking for professional repairs; in case of emergency, you can use the on-screen keyboard, voice input or external keyboard to solve the problem.

If a key on your laptop keyboard breaks, don't rush to replace it with a new device. This situation is quite common, and there are actually many solutions. The key depends on how you deal with it.

Check if it is a software problem first

Sometimes you think the hardware is broken, but it is actually a problem with the system or driver. You can try a few simple troubleshooting steps first:

• Switch the keyboard to external mode (if any) to see if the keys are normal
• Use the system's own screen keyboard to test the key response
• Check if there are any recent updates to the system or installation of software that causes abnormalities
• Check whether the keyboard language and layout are correct in Settings

If all of this is OK, but the key still doesn't work, it's likely that it's physically damaged.

Try to fix or replace the keys

If it is a mechanical structure problem, such as the key cap being loose, stuck or completely falling off, you can consider repairing it yourself:

• See if you can find original accessories, or go to the second-hand market to find a keyboard of the same model
• Use a plastic pick to carefully remove the bad keys and observe whether the film or contacts underneath are damaged.
• If the keycaps are just gone, there are general-purpose keycaps sold online, and the price is not high
• Be careful not to press too hard, some thin and light notebooks have relatively fragile keyboard structures

Of course, if you don’t have strong hands-on ability, it is recommended to find a professional maintenance personnel to prevent the more you repair it, it will get worse.

Use alternative input methods to respond to emergency response

If the repair cannot be done in a while and I am anxious to use the computer, you can try the following method:

• Enable the system's own on-screen keyboard (Windows can be turned on in "Easy Use")
• Using voice input function to type, although it is inefficient, it can be used to respond to emergency
• Connect an external USB or Bluetooth keyboard, which can be done with a few dozen yuan inexpensive amounts.

These methods are not long-term solutions, but at least they will allow you to continue working or studying.

Basically that's it. When encountering the key caps are broken or the keys are ineffective, don’t panic. First judge the problem, then decide whether to repair or how to deal with it.
