I am having trouble with an Advent 7088 laptop running Windows XP Home. Initially I was getting the ntldr missing error message on boot up but was unable to boot into recovery console to repair the boot sector. I tried using a usb keyboard to boot from the XP cd as the laptop has no OS/2 ports but still no luck even though I know the keyboard works on other machines. I took the laptop apart to remove the cmos battery to see if a cmos reset would work and now get "CMOS Settings Wrong...CMOS Date/Time Not Set...Press F1 to Run SETUP....Press F2 to load default values and continue". I have taken off the panel that includes the power button to check the ribbon is correctly fitted, the power button works fine but none of the other keys seem to work. Is this a keyboard problem or motherboard problem? Any suggestion are really welcome as I am hitting a brickwall at the moment!!
