Ctrl+Shift+L brings up the Calculator Rather Than Filter in Excel 2010 with Window 7

Hi, I recently purchased a HP laptop that has Windows 7 Home Premium and Office 2010. What used to bring up the filter command, Ctrl+Shift+L, opens the calculator and I cannot figure out how to change this.

Has anyone else had this issue? I don't know if it's the HP Laptop, Windows 7 or Office 2010 since everything is new. The laptop is HP Pavilion dv6-2157. Any help would be appreciated.

Have you tried right clicking on the Calculator exe icon and going to properties? If a shortcut is set, it should show it there.
