Cannot boot on battery when undocked because the system thinks its still docked

Talking about a Dell Latitude D800, it will boot up normally with only AC power, but when you have it undocked, it completes post, then gives you an error message stating that it cannot boot because the system is docked and it only detects battery power. The BIOS has been flashed to the latest revision, and in BIOS docking status reads as Undocked. We've attempted to delete the Hardware Profiles, there were 2 when we went in there, could not delete the 1st profile labeled CURRENT, deleted the secondary and created a new one, which named itself Undocked, but we can't seem to switch between these HW profiles, and allow the portable to boot on battery power when its undocked. System is running Windows 2k.

Can you boot this thing with a bootable floppy or CD (any bootable will do)? Try it undocked. What happens? If it boots properly, you may have a w2k problem. If it doesn't boot, you may have to reset your CMOS settings and/or look for a hardware problem (bad/dirty docking connector etc).

Don't believe that we've tried booting to any media, will definitely give that a shot tomorrow to determine OS or HW fault. But as far as resetting the CMOS settings, what are you thinking of when you say that. We've flashed the BIOS to the latest rev. and reset the BIOS defaults, and we 'reset' the system by disconnecting all power and holding the power button to release flea power. None of these things have worked thus far. If memory serves me correctly, the system board had recently been replaced - which would have included the docking port (not to say that there couldn't be an issue still, but it is unlikely) - and is the reason why we flashed the BIOS in the first place.
Chew on that, I will post more info tomorrow, including what happens when we attempt to boot from bootable media.

Chewing...

The CMOS part of BIOS is changeable through the BIOS setup program. CMOS settings can also be altered by accident and you can have corruption in CMOS memory. A "reset" removes power to the CMOS memory (by removing the CMOS battery or by closing a pair of contact pins on the mobo) and resetores the defaults from the non-volatile part of BIOS. Any specialized settings will have to be re-entered into CMOS at next startup, from the BIOS setup program.

Flashing the BIOS changes the non-volatile part, but it doesn't necessarily clean out CMOS settings and that's why I suggested you clear CMOS (if this is at all possible on this laptop). Resetting BIOS defaults is enough, sometimes....
