This guide provides instructions to diagnose and replace a faulty keyboard on a Lenovo IdeaPad G50-45 series laptop.
The keyboard is used as the primary text entry interface between the user and electronic device. The keyboard functions to take mechanical input from the user and produce digital text on screen.
To determine if your keyboard is broken and needs replacing, check for the following conditions:
- Sticking keys
- Keys are difficult to press
- Some or all keys fail to respond by not producing text on screen
- Keys detach and will not stay in place
If you have determined that any one or combination of the above are present, your laptop will require a replacement keyboard. This may seem daunting, however, due to the simple design of Lenovo’s Essential line of laptops, repairs are relatively straight forward and easy to complete with step-by-step instructions.
Before beginning the step-by-step keyboard replacement process, be sure to disconnect the laptop from any power source and remove the battery to avoid damage to the electronics.

Great guide! I struggled with the connector release, until I noted that on my Lenovo 505s the release tab is black AND opens from the other side… oh well, resolved without great damage.

I had an issue with the numbers at the top of alphabets. Some keys didn't work. I followed the instructions above to clean up the keyboard and hoped that would work. I could successfully remove and reassemble the keyboard but that didn't solve it.
I read it somewhere that this could be a hardware issue and the whole keyboard needs to changed. Is it really the case? Can't few keys be changed or fixed somehow?
Thank you.
