How do I fix a laptop keyboard ?

[smithJames]

---

It is an Acer Extensa 4620-4648 laptop. I stopped using it years ago because about half of the keys were no longer working. (random keys, its not just the left side or right side) I've started it up a few times over the years and it still works fine, its just they Acer Extensa 4620-4648 Keyboard keys that don'tt work. So i was wondering if there was a somewhat easy fix? I am not a computer genius and have never taken apart a computer or laptop before. Thanks

Try og clean ang contact/connection sa keyboard og sa motherboard bro. Works sometimes....if dli it's time to replace na gyd tingali.
