Set notebook on by default turn off Num Lock

The recent notebook power on by default on the NUM LOCK numeric keypad, plus my NUM LOCK led may be exposed because of poor contact, can not see clearly, resulting in my input password is quite troublesome. I got a lot of surfing on the internet. The way to turn NUM LOCK off by default is generally to let the BIOS setting off, but my Sony little punk doesn't have that option in the BIOS. Find another way to help other people with similar problems.

Method:
Start –> run –> input regedit–> find the hk_users–> selection. Default–> Control panel–> Keyboard, double-click on the right initialkeyboardindicators and change the value to 1. Conversely, if you want to set the default NUM LOCK keypad turned on, change the value to 2.
