Solved! Keyboard number light stays on

[bahaman]

Hello all.I have a toshiba satellite P755 running Windows 7 with a keyboard problem.One morning when I turned it on the number lock light was on ,and in the password box it was just repeating some number or letter,as if a button was stuck down.
So I bought a new keyboard,same problem again! But when I plug in a mechanical keyboard it works just fine.But I cant drag around a keyboard with me everywhere I go.
Any solutions?!
Thanks

So even with num lock turned off it's still typing numbers? Nothing happened to the system before the issue started, dropped, spilled on, anything? If a replacement keyboard did not help, could be the motherboard connections with the issue.
