The middle mouse button needs to be pressed down really hard on my Lenovo ThinkPad X220. I have removed the key cap to see if anything is stuck in there but it all looks clean. I also removed and put back in the little rubber membrane to see if that helped at all. would really appreciate some advice on how to troubleshoot and/or fix the problem please?

Sorry if this is in the wrong category it was not immediately obvious to me where to put it.
 


Thanks for replying. unfortunately on the X220 the mouse buttons are part of the keyboard. would have to replace the whole thing and the original keyboard replacements are ludicrously expensive. there are things like the greencell replacements but they are not the same as the original keyboard. I was hoping to fix it rather than replace it because I really like the original keyboard on this laptop.

also I probably should have mentioned that the mouse buttons where part of the keyboard in my first post, but this also means that the work in almost exactly the same way as the letter keys do as far as I can tell.
