can't use a shortcut in laptop

[Flicker]

Hi,

This problem seems stupid but I really in trouble and need your help. Currently, I used Windows 7 with Microsoft Excel 2010 in Lenovo Thinkpad laptop. I notice that I cannot use an Excel keyboard shortcut to add row, delete row and other shortcut i.e. remove border

Normally, I used following shortcut;

- Ctrl + shift + '=' (beside backspace) or Ctrl + '+' will add new row to the row you currently select in Excel.
- Ctrl + '-' (beside '0' number) will remove a select row in Excel.

However, now I can't use any of those shortcut anymore. I have to turn on "numlock" and use '/' button which very complicate for me.

I try other machine that have Windows 7 and Excel 2007 and it came out that the above shortcut work fine. My old system use Windows XP and Excel 2010 also work fine as well.

Anybody know what's happen with my system?

Do some of the keys have blue captions on them and there's a key called Fn (bottom-left-ish).
