Dell Latitude D800- Keyboard and mouse stop working when undocked.
I have a USB keyboard and mouse jacked in to the docking station at work. However, after performing a complete shutdown, then undocking and taking laptop home, I boot at home and the on-board keyboard, touchpanel pointer, as well as the little pointer nipple between the G&H keys are completely non responsive. Same with any external input device I might plug directly into the laptop's onboard USB ports.
I am able to hit F2 during bios initialization but I see no bios settings that might be helpful.
If I let it boot up without launching bios setup, then Once windows starts, when it is just a plain screen while windows is still loading, the onboard pointer works for a brief period, but then freezes just before the "Insert Card or Press CTL=Alt-Delete to Login" welcome message appears. At that point all input devices are dead. It seems that Dell and Bios are kicking things off right, but that Windows is deciding it doesn't want to talk to any input devices.
Some times when you plug a dock in, and turn it on, they will load them into the drivers and when you unplug it, it gets confused and when you boot it up it has to re-install the original drivers and does this while its booting.
This happens alot with the GX620 desktops. If you pull a USB keyboard out while its off and plug it back into a different USB port and tun it on. It wont work right away.
We end up having to let it sit at the login screen for a while till it reloads the drivers to the new USB port.
You will know if yours is doing this as the Hard drive light will be flickering and running.
Try booting it up and letting it load windows and waiting a few minutes.

I may have addressed this question earlier. If your Dell shows absolutely no sign of life... no LEDs, no nothing and you know for certain the battery and/or power adapter is good then...
If you have access to a docking station (ANY Dell dock that will mate with the bottom connector on your D800), put the D800 in the dock and use the power button on the docking station.
If the laptop powers up, you may have a simply problem with the laptop "Press to turn on" button.
ABOVE THE LAPTOP KEYBOARD...
Use a small flat screwdriver blade to remove the Center Control Cover (just beneath the display/cover hinge and above the F1-F12 keys). Locate the cover's flat ribbon cable connector above the Page Up key. Pull off and carefully reinstall. Try the power button now. If it works, put everything back together. Otherwise seek profession help.
Sounds like a compatibility issue between your Dell and the Docking station. I would say make sure the software for your docking station is installed properly, and update the software before connecting again.
unplug everything from the docking station, and press and hold the power button for about 15 seconds. Afterwards, plug in only the power and the monitor to the docking station and dock the laptop (make sure the laptop is turned off before docking and turn on after docking). If you still have issues it could still be hardware or software at this point. If you do not have issues, plug in one thing at a time to the docking station (mouse, keyboard, ect.) and restart the laptop each time until the problem starts again. this is how you will know if a device in the DS is causing the issue. if your monitor is vga (port on back of docking station where monitor is plugged into is blue) try plugging it directly into the laptop. also try plugging in the keyboard and mouse directly into the laptop (if they are usb) and anything else you may have plugged into the DS. This will be a better way of testing your devices. If all devices work fine, i would say that it could be more of a hardware issue with your DS.
First option if using Windows XP is to undock the system then delete the Docked hardware profile in Device Manager, Hardware Tab, Hardware Profiles. Once deleted, power off, dock the system, boot, Profile recreated.
Make sure power is off for both the laptop and the docking station. Plug your keyboard and mouse into the docking station. Dock the D630 to the docking station and then power on docking station. This should then turn on your D630. Your D630 should detect the keyboard and mouse.
If the docking station has no power:
Verify that the power cord, AC adaptor, etc. is plugged in. If the items listed seem to be in order,
there may be a problem with the power going into the docking station. (AC adaptor?)
support.dell.com will have the specific details for your D630 and your docking station, et al.
You can try to update any system utilities drivers and docking station drivers. However, I found that with IBM and Gateway, when you remove a running machine from the docking station they tend to glitch just a bit and when you redock them they have issues. Your issue is the docking station attachments, I've also seen issues with the monitor only, mouse only and keyboard on the laptop, all not working. I've had a couple that if I used the "safely remove hardware" then they would work when removed then redocked, but not all machines give the safely remove hardware option with the docking station. If yours does, try that. If it doesn't and there are no driver updates or the updates don't work, then, unfortunately, I'm afraid you'll just have to live with restarting after every redock. One other thing you might try is, after redocking, do a hardware search. It may find the attachments. I know this is also a pain, but it may be easier than rebooting every time.
