Re: Keyboard J, U, and spacebar not working
The keyboard may need cleaning or is broken.
To clean it, you could get a can of canned air, tip the laptop on it's side or upside down (carefully!) and blow out under the keys using small shots of air.
If that doesn't do it, you can try hooking up a regular PC keyboard using a regular PS/2 Keyboard or a USB keyboard and see if that will work for you.
You may be able to find a replacement keyboard online, but they can be tricky to replace.

The reason for this happening is that the metal bar under your spacebar is not properly attached. It's time consuming to properly fix it, but it's an easy fix at that.
All you need to do is remove your spacebar and metal bar (shaped somewhat like a tall C, if held sideways). On the bottom of the spacebar will be approximately 2-3 small clips in which the metal bar will snap into. Once snapped into place, you will want to look at the area where the spacebar goes. There should be two small clips at each end. With the metal bar clipped into the spacebar, you want to place the "ends" of the metal bar under the clips on the keyboard and very carefully place the spacebar into the hole on the keyboard and snap it into place. Now test it out and it should work fine. If not, it's likely that the metal bar came out from under the keyboard clips. The annoying part is snapping the spacebar into place without having the metal piece come out from under those clips, so you may need to perform this task a few times.
Hook a external keyboard, if okay! problem with the laptop keyboard. Try a system restore and bring the computer back to a earlier time before this happened, just might work. The keyboard can be disabled from the bios setting I don't see how it can be done any other way.
Hi, I'm afraid that your recovery CD's won't help you get the space bar working. There could well be dust, biscuit crumbs, hairs etc that's preventing the spacebar from working, turn the laptop off but don't close the lid, stand the laptop on it's side and get yourself a clean, dry paintbrush. Start to brush the keys and gently tap the keyboard with the other end of the brush to knock out any foreign objects that could be trapped under the spacebar. Once your happy it's clean turn the laptop on and see if the spacebar works. If you still have the same symptoms then the keyboard will have to be replaced. You can use the on-screen keyboard to substitute for the spacebar for the time being.
only two possibilities, first is the rocker springs at each end or the bar are causingit to not make contact. or the bubble switches under the keyboard. I had a similar problem on an inspiron 6400 and I had to VERY CAREFULLY remove the keyboard,then the button to reach the bubble switch which had lost the plastic bushing that covered the shorting contact, good luck given the insane price that dell wanted for a new keyboard fixing it myself was the option.
