A budget Windows 8 notebook released in 2012. Model number: 550P5C.

Some buttons dont work

~ 5 keys in different places stopped working at the same time. What became the reason is not clear.

I removed the top cover and lining, cleaned everything. There is no effect. I put a photo.

What is next step I can do?
