Solved! Bubble formed underneath keyboard

[kemal494]

Hello everyone, my Lenovo Z510 laptop keyboard has a vertical row of keys that do not do anything when pressed (namely volume down, 3, e, d and c). However when I press those keys while also pressing down the gaps between the keys, they work. After I disassembled my laptop, I have found a tiny bubble underneath the keyboard just under the keys d and e. I believe it is the reason why this bizarre situation happens, but have no idea about how to fix it. I would really appreciate it if anyone would have a piece of advice for me.

sounds like you just need to replace it, I would look directly at the spot beneath it to make sure it wasn't cause by a heatsink

The bubble is directly over the fan, so it could be very well the cause. Thank you.
