Use this guide to clean or replace the keyboard in your Lenovo ThinkPad L440 laptop.

The keyboard is a vital component to the laptop, allowing the user to input letters and numbers. A failing keyboard will prevent you from accessing your computer, if it is password protected, and prevent you from editing files or accessing the web. Some signs that your keyboard is failing are no input, either from certain or all buttons, or keys that are stuck/loose.

Before using this guide, consult our troubleshooting page. In some cases, what looks like a faulty keyboard can actually be lag from too many background applications, or outdated software.

Please note that if your keyboard has had any water damage, drink spilled, etc., this guide may not fix those issues.
