[EXObookie]

Hai guys,

 

On my Xiaomi notebook pro laptop both alt buttons have stopped working a month ago. At first it worked after pressing it 5 or 6 times in sucsession.But now its not regestering at all. I have tried with a external keyboard and on that keyboard it works. So maybe you guys have a fix.. I hope... pls Help....

Get a can of air and blow the keyboard out from all the crumbs.

Laptop keyboards can be changed easily if cleaning doesn't fit it.
