HP keyboard works in bios, not in windows

    My Hp laptop xf335 ze1000 series laptop keyboard works in the bios but when the laptop boots to windows the keyboard and mouse will not respond.  I can install an external keyboard and mouse and get it to work, but I like to travel with my laptop, and these items are cumbersome.  
I have reinstalled windows xp pro full edition several times as well as the emergency disks that came with the computer.  I have downloaded and installed the lastest drivers for the touchpad, and the keyboard will usually work when I reboot as required but upon the next reboot, the keyboard does not work.  I have never gotten the mouse to work after this problem came up.  I have even updated the bios (several times), and again the keyboard will usually work 1 time upon reboot (provided the system reboots, which it doesn't always do after reinstalling the touchpad drivers and updating the bios or deleting the keyboard in hardware devices, which I have done).  After that I am back to the corded external usb keyboard and mouse, the computer has no ps2 ports.
    I reset the computer through the paperclip hole on the bottom (outside of updating the bios), with no good luck.
Please help!

I find that I give the same suggestion to many problems, but here goes:
To determine if this is hardware or software (O/S or drivers) you should boot up your computer with another O/S. If you can boot with a DOS or win9X boot floppy, try the kb at the command prompt or run something like old DOS "edit" or something to see if the KB works. If you can load DOS mouse drivers, the touchpad will probably be recognised as a PS/2 mouse and it can be tested as well.

If a boot floppy is not a viable solution, you could try a live CD Linux distribution like Knoppix (www.knoppix.org) or ubuntu (www.ubuntu.org). Quite harmless but very useful for testing the hardware in another environment than your usual windows.

If the hardware works in another O/S, it is a windows/driver issue. If it keeps acting up, it may very well be a problem with the PS/2 circuitry in your laptop.

It took me a while but I finally was able to load Linux, Fedora Core 3.  The keyboard works now, but the mouse does not.  It is a lot easier to carry a mouse than a keyboard.  Thanks.

Odd that your mouse (I suspect it's a touchpad, right?) doesn't work. If you run Linux, you can use the command:

dmesg | less <Enter>

at the prompt in a terminal window and see if the touchpad is at all detected. It may be defective.
