Some key on built

Hi,

My Macbook Pro late 2013 running macOS Sierra v.10. 12.5 can't use more keys such as:

7 8 9 u i o j k l m "," and "/"

I try restore keyboard layout in Settings/Keyboard/Shortcuts and press restore default in "Keyboard" and "Input Sources" that's still can't use.

But I try to log in guest account and type in TextEdit, all key working normally.

Please give me the way to solve this.

Thank you.

You have accidentally turned on the "Num lock".

Look for it in one of function keys (possibly F6, or near it).

You may have to press it with or without holding the Fn key (depending on your settings).

Go to preferences,accessibility, then mouse and trackpad. Make sure to uncheck the box that says "Enable Mouse Keys". Goodluck
