    I have a similar problem but different keys. Same keyboard and shortly after purchase the 3, left shift and main enter key do not function. I'm going to try to return it for a new one, I think there are the cheapest M$ keyboards so they are going to be prone to failure. M$ is like the luxury clothing industry, expect you to pay top dollar when they pay the workers (china and slave labor) next to nothing.

    I downloaded the latest drivers from M$, may help you, didn't help me. My system auto detected it as something other than the 2000 when it is and the drivers were the only way to correct this incorrect detection. My keyboard came with no drivers.

    Same here: some of the keys stop working every now and then. I think it's a software related prolem (yes there it is again), ecause the keyoard is almost new and when I disinstall all the drivers and restart the computer it works fine again for a couple of hours. Some overload, sneaky virus or even a MS "solution" for MS software that hasn't passed the Genuine Advantage check?

    i opened the keyboard and dusted the inside off because i didn't know what else to do. I havn't found any help online. does anyone know how to find a solution or do i have to buy a new keyboard? if i do then does anyone know of a keyboard that wont do this?

    its been really annoying me. its been annoying me even more trying to find a solution because its my 'k' key that doesn't work on my keyboard. you can see how that is extremely annoying?

Mine does the same thing only sometimes the keys work, then hours later they decide to stop working.

It's a pain in the **** but if you take out all the screws, take the top cover off then put it back on, for some reason the keys start working again.

The problem will come back though. I'm considering keeping the screws out so I can just pop it apart whenever the keys stop working again.

    Because this site doesn't seem to allow web site URLS to be posted, then I recommend using Google - search for "southpark whirlpool comfort curve 2000", and there it will link to a solution.

I bought this MS Comfort Curve Keyboard in mid 2010, this new technology is wonderful and superb, the keyboard is sheer pleasure to use, that is when it is working! The keys feel really soft and silent, so, it wont wake the baby up. But after only 3 days of usage, that is about 15 hours of typing documents, few keys at random stopped working, this was my 1st ever horror story. This funky MS Comfort Curve Keyboard turned out to be real nasty piece of SM. So, when I unscrewed the keyboard to take it apart, it was good to see that it had no mechanical parts, just two A4 size plastic sheets inside the KB, that have electric circuit printed on them, and on top of that lies a plastic mat with lots of nipples, that you can squeeze with your keys. The fault that few keys had stopped working was due to too much static electric charge build up on these cheep plastic sheets just after few hour usage, and that cuts the keys off. I wish MS(SM) had used better or excellent quality plastic sheets, even one made out of good plastic shopping bag would have done a great job.

So, looks like to keep the cost down for this really cool MS Comfort Curve Keyboard, MS got them made in china in some cheep crazy train factory. Probably like Apple
s Book it was a great idea, was this risk worth taking by Microsoft? At this moment in year 2010. Two off the worlds leading computer software and gadget producer are desperately seeking for two opposite solutions; Apple is looking for a signal transmission Aerial as powerful as microwave oven to spit-roast their customers with pleasure, and Microsoft is looking for quick Lightning conductor to ground the bad vibe signal from ampple thunderous discharge?

This problematic MS Comfort Curve Keyboard can be temporarily repaired, it takes about 15 min max. Unscrew and take apart keyboard, and sensibly discharge the 2 A4 size plastic sheet that have electric circuit printed on them, and that
s it. The keyboard will work only for few hours or few days, so, now you will have to turn into a baby sitter for this pest keyboard, as you will have to nipple feed the monster keyboard all over again, you will have to strip down the keyboard again and again, while it strips you L Till one day some tech guy from Microsoft sneaks onto YouTube to tells us how to permanently fix this keyboard, with hairpins and paperclips.

Some review say that only a small % these SM Comfort Curve Keyboard are faulty. I wonder if the Microsoft Comfort Curve Keyboard were made by Toyota or by some toy or baby milk factory in China J

    Open up the keyboard and tighten the relevant screw that keeps the 'ground tab' (of the top-layer printed circuit plastic sheet). Also, use the sticky aluminium foil tape to couple together the top and bottom printed-circuited sheets - but make sure that the foil tape does not cover any of the printed circuits themselves (because you definitely don't want to cause short circuits). So, basically, you just want to use a single strip of aluminium tape - where one portion of it is stuck to the first printed-circuit sheet, and another portion of the tape is stuck to the other printed-circuit sheet - such as shown in the illustration below.

    Ignore my comment about the 'illustration', because the fixya site appears to remove 'carriage returns' in my post, which has messed up my 'ASCII character' illustration. Anyway, I forgot to mention that once the foil sheet is stuck/attached to the printed-circuit sheets, use finger nails or anything to rub the foil really hard in order to get a very close bond between the foil sheet and the printed-circuit plastic sheets (because we want to couple 'electrically' the two printed-circuit sheets).

  • Kenny Jan 01, 2011

    I also forgot to mention that it is best to also apply small dabs of electrically conductive 'Wire Glue TM' to some of the boundaries between the foil tape and the printed-circuit sheets - this would ensure electrical coupling between the tape and the plastic sheets. I think that just sticking foil tape to the plastic might not be good enough - so it should be beneficial to use electrically conductive glue to help things along.

    Also adding photos to give examples of what I've done to try tackle the unresponsive key(s) issue.

Help, I'm getting no sound on my dell dimension E520, with Vista. Have uninstalled & reinstalled the driver. The speaker icon has a red x on it & volume is always on 0. When I try to open


Check whether you have muted the audio by using the keyboard hot keys.

I mean if you are using multimedia keyboard then there will be a button to enable/disable audio or mute/unmute audio. try pressing that again.

If problem persists download your audio driver from dell website, below is the link:

It seems that the keyboard is not communicating correctly with Windows 7 or your operating system, maybe even with your Dell PC, remember that Dells, Compaq's and other major PC companies program their systems so that consumers will only purchase their factory products. First make sure that you have installed the correct drivers for that keyboard, also try swapping with a friends keyboard and see if the problem continues if it stops with a keyboard swap then the Microsoft keyboard is not compatible which seems rare but possible. Good luck.

How is the easiest way to replace the shift key it has the metal bracket under it. The keyboard in question is a microsoft comfort 2000.
