B5400 Touchpad mouse button broken

I have a Lenovo B5400 laptop that I bought from my friend after he had broken it.

I fixed it up, but the only thing I couldn't fix was the left mouse button on the touchpad.

It's pretty much dead, barely works. I've taken the laptop apart and noticed there's nothing wrong with the circuit board, it's just that some plastic has broken from the button. And guess what, it's a non-replaceable part.


What to do? It's a shame because apart from this one button it's in great shape.

Re: B5400 Touchpad mouse button broken

Hi Finlandguy,


Welcome to the Community Forums.


Touchpad for this model is not available separately but includes the entire uppercase cover so there is no part number specific to touchpad only and would need to get the entire uppercase instead.


You can check locally in your location is some refurbished part is available else cheapest solution can be using an external USB or wireless mouse at the moment.
