Keyboard failure

Hi.
 
I have a Dell dimension 9150 with dell keyboard and dell mouse (both USB).
 
My problem is that a couple of days ago I was playing my computer when it suddenly froze. I shut down the computer and turned it on again. Now when it is booting it stops for a while on the first Dell screen. After 20 seconds it moves on but writes: "Keyboard Failure".
The result of this is that i can neither use my keyboard nor my mouse which indicates that i am rather stuck!!!
 
I can't press the f1, f2 og f12 bottons.
I have tried to use the other USB-entries.
Both the keyboard and the mouse works perfectly on my laptop.
 
 
Can anyone please help me?

Re: Keyboard failure

Gunnergunner,

Thank you for using the Dell Community Forum.

Reseat the cables and make sure they are connected to the rear usb pors on the system. If that does not resolve the issue post back here in the forum.

Re: Keyboard failure

The cabels are inserted ind the ports on the back of the computer corresponding to the instructions in the manual.
 
Other ideas? Anyone?

Re: Keyboard failure

Can you test the keyboard on a different PC? Try all the other rear USB ports on the tower.

Re: Keyboard failure

Hi. I am having the same problem on my two-year-old (out of warranty) XPS 400. Suddenly I am getting "keyboard failue" during boot up. Many posters have said "hit F2" or "F8" but--hello--if the keyboad is disabled I can't hit anything!

I have tried all of the USB ports, front and back, and it makes no difference. I bought a new MS optical keyboard, and it does not work either.

Also, I cannot find a system disk so I am thinking the unit shipped without one. I saw somewhere on dell.com that Dell would send such a disk, but now I cannot find that page to request one.

Any practical suggestions would be appeciated.

Re: Keyboard failure

Something else to try that worked for me on my 410:

  • Power off PC
  • Unplug the power cord from the back of the PC
  • Press and hold the "power on" button for 20-30 seconds (this drains the remainder of power from the system)
  • Plug the power cord back into the PC
  • Power on PC and check for keyboard and mouse availability.

Re: Keyboard failure

I am having the same problem as the original poster - fixed a "frozen" situation by restarting, now get "keyboard failure" at boot on my XPS 400 purchased in Jan 06.   Seems like this is a common problem out there for Dell's.  Problem is definitely not the keyboard as it works on a laptop.  No PS2 connection, only USB.  No USB ports work, therefore can't do any diagnostics by keyboard.

Tried to "flash the bios" as suggested elsewhere on the 'net by playing with the jumper blocks.  did not work.  

a search of this failure on this site and on google generally will reveal that this has happened to lots of Dell buyers, yet there does not appear to be any solutions out there other than to replace the motherboard, i.e., buy a new computer.  would love for a moderator to address this. 

thanks

Re: Keyboard failure

What happens if you boot from Dell Windows Reinstallation CD, or other bootable CD? If keyboard works, you have a software failure. If not, you have motherboard or keyboard failure. Have you tried this keyboard on another PC or another keyboard on this PC?


Power off and disconnect PC from the wall. Press/hold power button for ~15 sec. Open the case and remove the battery from the motherboard. Leave it that way for a couple of hours or even overnight. Reinstall the battery (right-side up!) and see if it will boot with only USB keyboard and mouse, and monitor connected.


And you may need to do a Repair/Reinstall of XP.

Re: Keyboard failure

Nothing different happens upon using the CD.  Keyboard definitely works.  Have removed the battery previously, though not for hours, and no change.   I suspect it's the motherboard though I'm angry that it would go after less than 3 years of not very heavy use.  Can't figure out the part # for the motherboard in order to see how much it would cost to replace it.  Suggestions on how to find the part #?  Can one write directly to the liasions here to get their attention - as I've said before and as you can see from this thread alone, this is a widespread problem deserving of Dell's attention. thanks.

Re: Keyboard failure

srlawson,

When you power it on with the keyboard and mouse plugged into rear PC USB ports, what color are the Diagnostic Lights

and the Power button light?

  The motherboard part number is HG547 (Motherboard Service Kit for Prescott & Smithfield CPUs).
