Toshiba C55D-A keyboard problem

[ray_51]

My keyboard has been acting weird the Backspace, P, 6(top of keyboard), F, H, K, 4(top of keyboard), L, W, and the Number Lock light no longer works is this a driver issue or a hardware issue.

Sometimes, if you tip it upaside down and put it on your shoulder then pat its back as though you were burping a baby. Any dust, durt or toast crumbs will fall out and the keyboard might work properly.

If the affected keys were in adjacent blocks I'd say hardware but your's are spread out so it's a bit of a mystery.
