No Keyboard response on my laptop

I have the HP Pavillion Entertainment PC dv6000.

None of the keyboard shortcuts I have tried get any response at all. Here is a list of those tried:

Alt + Tab
Alt + Esc
F6
F10
Ctrl + Esc
Ctrl + Shift + Esc

I have a USB mouse with it and that is not expected to work, so once the OS boots successfully to the Lake Scene I can do nothing more except shut down the computer.
