Do you have a laptop with one or two broken keys on the keyboard? Would you like to replace these individual keys without replacing the whole keyboard? Yep, you can do that. Check out these instructions offered by MachinaElectronics.com
Keyboard Key Installation Guides.
Installation instructions for our replacement keyboard keys. Each guide works with many more models, including multiple brands.
You’ll find instructions for many different laptops including Compaq, Dell, Fujitsu, Gateway, HP, IBM, Panasonic, Sony and Toshiba. If you cannot find your laptop in the list, check out instructions for other laptops, they all similar.
If you still experience a problem installing the key on the keyboard and not sure how to assemble the plastic hinge mechanism located under the key, you can try this.
1. Unsnap another key from the keyboard. You’ll have to unsnap just the key cap so the plastic hinge mechanism stays attached to the keyboard.
2. Assemble the broken/missing key hinge mechanism the same way as it assembled under the key you just removed from the keyboard.
3. Install both keys back on the keyboard.
