Dell xps 400 keyboard and mouse not working, but the keyboard does work in when in service mode

It's a boat anchor. Why in the world did you disable USB ports?

Wireless/Bluetooth keyboards and mice can only be used with one device at a time it is like a bluetooth headset once it is paired with a phone it will 99.99% of the time only work with that phone and that phone only, Wireless keyboards and mice are setup on the same principal once they are paired up with 1 PC to use on another PC you have to remove the pairing. The worst case scenario is that the second PC's Wireless/Bluetooth has failed. I hope this helps.

Dear Sir:

I am recomending to go www. dell.com and go to troubleshooting section for diagnose the computer, the problem I see is driver some missing. You must need to reinstall. By that reason Run the Diagnose from Dell .

sincerely. God bless you.

Ram complaint

Hi, these instructions will help you, and "everything that you do for the Keyboard; apply the same instruction to the Mouse." First, click on the "Start" button, in the ["Start Search Window], Type: keyboard; the "Keyboard" Properties window will open. You can (Test) to see exactly how your keyboard is responding. If you are still having the same problem, (check, the Keyboard Status). "Update the Drivers," by clicking on the "Properties" button. Now in the event that neither of these solutions solve the problem, which I hope you shouldn't have to do anymore; "Uninstall the Keyboard. To "Uninstall the "Keyboard," do the following: Shut-down (turn- off completely); disconnect all the Keyboard Devices that are connected to the Computer. Next, turn-on the Computer, and go back to the "Keyboard Properties," next, click on the "Change Settings" button, next click on the "Driver" button, and select the "Uninstall" button. Once that is finished, shut-down the Computer again. Now you want to "Reconnect" all the devices that were connected before, and "Turn-on" the Computer. "You will repeat exactly what you did from the start, this will "Re-install the Keyboard. "Restart the Computer again after all changes have been made; this will ensure the changes take effect properly. "Rating the solution will let me know if it worked; or you may need further assistance, thanks."

Sounds like your USB circuit may have gotten fried due to a static discharge (assuming your keyboard and mouse are USB). You can purchase an "add-on" USB pci card or a PS2 Mouse and Keyboard.

Make sure you have the correct driver downloaded.

first make sure the keyboard is plugged in all the way. then make sure there isn't a button stuck on your keyboard all else fails wal mart has some cheap ones if it STILL presists. your PS/2 port may be messed up unless your using usb

BLOW IT OUT ON YOUR DEVICE MANAGER RE-START SYSTEM AND LET THE COMPUTER FIND IT ...HOPE THIS HELPS

Try to re-sync the keyboard to the computer. Here’s the procedure:
1) Turn the computer on.
2) Turn on the keyboard
3) Press the sync button on the rear of your computer’s left speaker.
4) Press the sync button on the keyboard. ( I believe it’s on the bottom of keyboard)

The sync button has a symbol next to it, (2 arrows going in clockwise direction).
Ensure that the keyboard battery has not run low.

If that doesn’t work, look for a Bluetooth icon in the lower right hand corner of your desktop and double click on it to open the Bluetooth configuration utility. See if there’s a configuration file for the keyboard. If there is, delete it and then re-detect Bluetooth devices.
Hope this helps.
