Laptop keyboard not working
I'm having problems with my carputer keyboard. It's a Patriot 2276, exactly the same as some Advent laptops. It was working last time I used it, but when I got it out it wouldn't boot properly. So, I replaced the CPU, I think the old one burnt out. But now when I boot it complains about a flat CMOS battery and says:
'Press F1 for Setup'
'Press F2 to continue'
This is normal, it always did this, but when I press F1 or F2, nothing happens. I've tried it with a keyboard from another laptop the same and tried with an external USB keyboard, but I still can't get passed it.
Has anyone else had simillar problems, or know whats wrong?
