Questions about keyboards that limit the number of buttons/or what buttons you can hit at a time.

Hey all. I have a question that I'm not sure if it's a setting I could alter, but my predicament is.....me being a lefty I have a weird key config. I use numpad 8,5,4,6 to walk up,down,left,right. I use numpad 0 to jump, and numpad enter to sprint. One thing I noticed, with just using a standard dell keyboard, if I'm holding numpad enter to sprint, and hit numpad 0 to jump it works fine and I can jump while sprinting. However, on my laptop that is not the case. While holding numpad enter and trying to hit numpad 0 on my laptop, it completely nullifies me hitting numpad 0 and I can't jump while sprinting(tested with the same game). So I'm wondering, is this a physical limit that the keyboards manufacturer(HP) put in place? Is there any setting I can alter in Windows 7 to change this? Thanks.

Here's some information about key rolling.

http://en.wikipedia.org/wiki/Rollover_(key)

It's usually a technical restriction that stops a certain amount of key being pressed. Through USB I believe it is 6, please correct me if I am wrong. With PS/2 and NKRO, it is unlimited.

Yes, in general with non gaming keyboard, you are limited in key strokes, that is why when I RMA'd my wireless keyboard and mouse a few years back and Logiteh wanted to replace with a certain keyboard and mouse, I was able to convince them to give me the G15 instead and they were good about it.

Ah I see. I definitely see some of the restrictions that I have. With both of my keyboards I can't press numpad 5(back) numpad 6(right) and numpad 0(jump) at the same time. Weird thing is, I can hit numpad 8(forward), numpad 4(left), and numpad 0(jump) and it works. I guess the other combination jams my keyboard(s) for some reason.

More good info that explains what you are seeing with certain key combos (along with a widget to test your keyboard):
