Notebook Software and How To Questions

Have only had this Victus for about a week. It has a numeric keypad, which I specifically wanted.  Home (7), Pg Up (9), End (1) and Pg Dn (3) are on the keypad (along with arrows on 2, 4, 6,8).  Incidentally Num Lock does not have an indicator light to show whether it's engaged or not, which is mainly a problem because of how this kb is set up. 

The only way to get Home (7), Pg Up (9), End (1) and Pg Dn (3) to work is with Num Lock OFF.  There is no option for Home etc. with Num Lock engaged.  This is a major issue since I keep Num Lock on routinely and also use the Home/End keys a lot in my work. Having to disengage Num Lock to use Home etc. to get around in a document (and then re-engage it so it works as a keypad again instead of moving the cursor around) is disruptive. 

I wondered if this configuration choice was because this is a gaming laptop (not why I bought it). 

I've never had to mess around with keyboard coding, anyone have any ideas? I was thinking I could probably get used to holding down the Fn key to use the directional keys when Num Lock is engaged, if I could force that somehow.
