Spacebar.quit.working. i.removed.sticking.spacebar.to.clean.gunk.underneath.......after.replacing.it.does does.notwork.???...it..acts.and.feels.normal...but..still.not.working.?..what.could.be wrong.

Greetings,

You may have some small item underneath the spacebar. The spacebar will "pop up" if you use a screwdriver or something to pry it up from the keyboard. Insert it near the B on the top side of the spacebar and pry up towards you. Clean out from underneath and reattach it.

you will need to replace the keyboard. we see this alot,keyboard starts to fall apart due to age. batteries are only used to hold tab and margin positions in memory. machine works fine without batteries.

Get a Electrical/Electronic solvent spray from RS, give it a good spray (with Power Off!) and operate it lots of times. The spray will evaporate naturally and may remove the gunk! Ian.

Use a credit card or plastic Id, insert it and bend it gently. If it fails, you can use 2 cards, one on each side of the spacebar.

If after all you are unable to remove the spacebar, try removing the keys around it, just remember their distribution.

Beware, the spacebar is a little more complicated to put back in place compared to the other keys, as you said, there is a spring.

You have it in backwards.

The pad has slipped.. open KB and reset.

i have already posted the solution to my problem.....but i will tell you in more specifics what transpired.........after removing my spacebar.....i used electric pre-shave (an alcohol based solutions with a slight amount of lubrication).......with a few drops of that and a q-tip i cleaned the black tarry mass that had accumulated underneath the space bar most likely from spilled pop,coffee,pancake syrup,cat hairs,and only god knows what else...........after replacing it it worked fine mechanically and physically but did not work on the screen......after a day or two it started working .....i guess the alcohol needed to dry out .....i did put two drops down the tube that had a pad at the bottom (contacts underneath it ).........everything working better than new now .......thanks for being here to help.........

Have you tried applying pressure gently until it snaps back in place? That could be the issue, is that the spacebar unsnapped itself when you were cleaning it. If you were using compressed air (canned air) then you may have blown something underneath it and it jammed itself in there. Trying turning the keyboard upside down and gently tapping it on a hard surface to see if anything else comes out.

Just solved it, after a bit of tinkering...

the prongs of the floating plastic frame need to sit inside the clips of the spacebar key, you can't just clip it back on with the prongs either up or down. It's fiddly, you need a paperclip or thin screwdriver to do it, but it's stopped the sticking problem.

did you check to make sure that the springs and bar under the spacebar are seated correclty?
