You can place light blocking tape over the numlock light if that bothers you. Its not a failure.
The shutdown issue varies with the OS. You could have a Macintosh, PC or other computer since this forum doesn't distinguish what you could have. Share with the forum such details in the future. In the meantime, the following two links are about shutdown issues with the common Windows OS's.
