Most laptops are like this. If your keyboard breaks you may as well buy an entire new machine. It will either cost too much to replace the keyboard, or the part won’t even exist anymore.
Framework is the only company that guarantees you can fix your laptop cheaply years after you bought it.
To replace the keyboard on a Dell, you have to disassemble the laptop. And I mean disassemble. The kit includes thermal paste.
Framework. A company not yet 6 years old. Call me when 15yrs goes by and they can provide a source for the keyboard.
