Windows 7 - Keyboard not registering every keystroke

I have an Acer Aspire 5732Z running under Windows 7 Home Premium and the keyboard seems to have a mind of it's own. When I am typing, particularly into input boxes like this one letter randomly fail to register, very frustrating, mostly vowels.
If it were the same keys every time then I could be sure it is a harware fault, but this is not the case, even the space bar fails on occasion.

Can anybody help?

Just a guess, go to keyboard in Control and adjust the settings, for delay, put it near fast. Mine is about 3/4 of the way.

Hi Richard,

I am having the same problems with my keyboard as the original poster: Input, mostly on Web forms, seems to "lose" keystrokes, possibly because I type too fast for it to catch everything. I found your solution because I was searching for my own post, and happened upon yours.

However, I do not understand your directions completely. My keyboard properties have a Repeat delay, but it is not fast or slow, it is long and short. Long is on the left, and Short is on the right, and the slider is about 2/3 toward Short. Which way should I move it, if at all? I also have Repeat rate, if that has anything to do with the problem. Mine has settings between slow and fast, and mine is all the way to the right, on the Fastest setting.

I would be very grateful for any advice you can give me, and will happily "rep" you for your assistance, if you would be so kind as to tell me how to do that.

Thanks in advance and best wishes,

~Antonio

Welcome Antonio,

My keyboard is just like yours, I mispoke. The settings is about 2/3 ot 3/4 toward short. I am sure we are set the same as that is the default setting. I doubt if the sollution worked, we never heard from th poster, again.

Not having the problem, myself, and not knowing anyone who has, I feel that the problem has something to do with the amount of force required to type with each letter.

My repeat rate is all the way to the right, too.

Hi Richard,

I do not think it has anything to do with the keyboard pressure, because my keyboard is also buffering to the screen at times, but only on Webpages. I have a program installed, called Protector Suite QL, from UPEK, which is a fingerprint reader. They intercept your Web registration/sign in inputs and offer to save the information under your fingerprint security. I have a feeling that their software might be the cause, because it runs in the background and senses when Web forms are being completed, especially logins.

I have emailed UPEK support, and they have been very good about getting back to me in the past. Maybe/hopefully, they will have a solution. I hope so, because this is driving me nuts!

Have a good night,

~Antonio

Why not make a system restore point and remove the software. See how the keyboard works. It can be reinstalled very easily using SR, again. If nothing else you will be sure of the cause. I, also, try to install very little on my computer. If you really need or like it keep it. I know that everyone has different cirucmstances and needs, but the last thing that I would want is a fingerprint reader.

If you had mentioned the fingerprint reader in your first post that would have been my first guess.

If it were my compuer and I called for help on the finger print reader, I would suspect that as a cause regardless of the answer that I received.

Ty for the rep, I truly feel that it is not earned. But, I will keep the problem in mind and repost if anything new is thought of. You keep us posted, possibly we can still solve this together.

I have read all of the replies to my original question with interest, none of the solutions offered have worked, I am sure the problem lies within IE8, there may be a clash with another application. I may well be that we have to wait for a windows update to solve the problem.

If you think that the problem is with IE. Go to tools>internet options>advanced>reset. It will remove all the add-ons which you can restore later.

Hi Richard,

Thanks for the suggestion about resetting IE8. I am happy to do this, but I would like a way short of doing complete system backup and restore, of saving the settings before I wipe them all out. Does IE8 have a way of saving all of my personal settings, so I do not have to recreate them from "scratch"?

Best,

~Antonio

Hello Richard and Geoff,

If only I could narrow down the time this actually started, then I could be more certain of the possible cause. However, in the absence of that, I am not going to do anything major at this point, because I have had this configuration for a while, and not had the problem for more than a few weeks. I think I said this in an earlier post, but over the weekend, I actually did do a system restore from a disc partition image I had created on March 14, and the problem was there before that date too. I guess, if I look at this from my 32 years of computer experience, it could be caused by anything. So many things that, in the absence of "hard" evidence, I do not want to go stabbing my way through my applications and settings just trying to find the cause. I feel that such an effort would be futile.

For what it's worth, I use the fingerprint reader to remember usernames and passwords for Web registrations, and for my Windows login. For the latter, it is just an alternative to typing a long password every time I boot my computer, and for the former, it is so that I do not have to maintain a list of usernames and passwords, as I would normally, because I have a cognitive disorder which makes it hard to remember these things.

What I find interesting is that, today I had to execute some commands at the command prompt. Just simple things, but I was amazed that I could even tell the responsiveness of the keystrokes was better there, even though it was just a small difference between that, and say, Office. I think it is interesting because every "layer" of application creates a small delay between the hardware and the OS. Most people probably would not even notice it, but I type around 97 words per minute, so I can.

I think I have just happened to stumble across the wrong combination of "application layers", and they have somehow interacted to create this delay. Windows, as it usually does, will probably one day just change some setting that changes this interaction and gets rid of the problem. Until that happens, I will continue to "troubleshoot as I go", and keep the forum (you guys) posted if I happen upon something that I do which fixes this.

My only request to you both is that you keep me "in your loop" if a solution to the problem comes along.

Thanks and have a good night!
