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.
