The following keys are not working consistently on my keyboard: 5 6 0 Caps Lock Del
There are times that I have to press them repeatedly before it works. Other times, they work effortlessly with normal pressure.
Does it probably just need cleaning, or is there a software/hardware issue?
I was hoping there's a way to fix this without having to go to a service center or replace the keys (I kind of don't know how to either, afraid I might damage it altogether), so thank you for your help!
I'm running Windows 7 on an MSI CX41 laptop.
