Keyboard input skips letters when typing quickly

I type very fast and noticed that if I type a word with a double letter (like two t's in 'letter), the second repeated character is often missing. If I type a bit slower, the problem is resolved.
Technically, this should not be a keyboard repeat issue, since it relates to two separate keystrokes, not holding down the key for repeat. Nonetheless, I set the repeat rate to max, the delay to minimum -- yet the problem persists.
It is very distinctly an issue with speed. My friends who type at a more moderate pace have no problem. In other words, it doesn't appear to be a defect particular to my machine. Rather, it is seems like a parameter that is just not capable of recognizing keystrokes in such rapid succession.
Note: I cannot reproduce the problem on a PC laptop, which seems to have a faster keyboard response.
Is this an OS issue that can be fixed with a hack? Or is this a limitation on the hardware?

My third defective macbook did the same thing after coming back from RSD repairs which included a keyboard replacement. If you didn't hit each key with a very deliberate stoke, it had a good chance of not being recognized. My fourth macbook has other issues but it does have a perfectly functioning keyboard now. My first defective macbook had sticking keys due to excess glue under the keys.
Amazing with something as simple as a keyboard, apple still can't get it right. This is the first device in almost 30 years of using and buying computers I've ever had to worry about a stupid keyboard working.
I'd suggest you visit a store which sells macbooks and see if the behaviour occurs there as well.

  • Keyboard producing extra letters when typing and impacting system performance

    I’m having some issues with my Mid-2010 MacBook Pro 15. The Apple tech guy was baffled at the symptoms I was experiencing; he was unable to help (the MacBook Pro itself has not been inspected) so I thought I would see if anyone else had a view as to what the issue could be. I’m happy to fix it myself if possible (I’m quite comfortable with doing repairs/upgrades/general maintenance on Macs and PCs at large) and would rather avoid a hefty fee from the Apple store or other repair services if it can be avoided (unless the error is due to faulty hardware where Apple will fix free of charge).
    The issue lies with using the internal keybaord. Most of the keys on the keyboard work just fine, a couple don’t, however when I use the internal keyboard it significantly slows down animations (i.e. clicking on the Applications icon on the dock will take a good 5-7 seconds for it to finish the pop-up). There hasn’t been any liquid spillage or suffered from any falls so I’m not quite sure how this problem came about. These are some of the issues/symptoms I’m having which may help in a diagnosis:
    -Shift key is stuck and the Mac will boot into Safe Mode on its own. Holding down the Option key upon pressing the power button until the spinning gear appears will allow the Mac to boot normally. I can use an external keyboard and the Mac runs just fine. However, if I use the internal keyboard....
    -Animations run slowly and it cannot load graphics programs such as iMovie. (An error message pops up, but I do not have this latop with me at time of posting this to find what it is. If you need to know what the error message is, let me know and I will post it here when I get home). Even though I’m in ‘normal mode’ for less of a better term, using the internal keyboard will result in the Mac performing like it is in 'safe mode' until…
    -Pressing any key on an external keyboard. The slow animation issue is resolved (i.e. clicking on the Application icon on dock pops up in less than a second as per normal) and the Mac will return to running as normal and everything is very responsive. iMovie will now load correctly (without the error message).
    -Some letters when pressed on the internal keyboard will type another letter directly after it (e.g. If pressing ‘q’ it will type as ‘QT’ (in caps due to the Shift key being stuck), same for pressing ‘t’ will display as “TQ”. This also happens to ‘a’ as it will type ‘AB’ and ‘b’ where it will display ‘BA’. In total about 6 or 7 keys around the keyboard are affected where pressing one key will result in it being typed in caps AND a second correspoding letter. Pressing that second corresponding letter will also type in caps and it's "linked" key.
    -Selecting individual files with the track pad (after pressing a key on the internal keyboard) will pick multiple items within a folder as if you were clicking and dragging to select multiple files. If I click on one file and move the cursor (without holding the click or ‘touch to drag’) to a file below, it will select everything between the two selections. Pressing a key on the external keyboard returns everything including the track pad back to normal
    I’ve performed a clean install of Snow Leopard which took a little longer than usual. The install disc took some time to actually load into the installation screen, roughly 5-7 minutes longer. The external keyboard doesn’t appear to work on boot up until I get to the log in screen. I’ve cleaned inside Mac from what minimal dust was there. Finally, I’ve been unable to reset the PRAM or SMC as the laptop boots into Safe Mode due to the Shift key being stuck and the external keyboard not being recognised until I reach the log in screen to enter my password. Other keys don’t appear to be working (i.e. holding down C to boot from disc and other key commands on start-up do not work), the only key on the internal keyboard that appear to work on boot is Option which allows me to bypass the 'auto-safe mode' boot.
    I’m quite sure this is hardware related and if feasible I will fix myself, if not I’m happy to use an external keyboard (except when needing to perform boot commands which is where I’ll run into some issues).System specs are as follows:
    MacBook Pro 15 - Mid 2010 (April)
    2.4GHz Intel Core i5
    4GB RAM
    160GB hard drive
    NVIDIA GeForce GT330M 256MB
    I’d appreciate any possible answers you have. Apologies if this has been posted elsewhere, I’m quite sure this is a unique issue so I’d be surprised to learn someone else has had this problem too after all the hours of research I’ve done!
    Thanks.

    lol, I was going to add "as long as it's not doing that all the time" ...but was hoping for the quick fix. You might want to check your Activity Monitor and see which program or background process is causing the activity ...have you installed anything lately that coincided with this problem? You also might want to try booting into Safe Mode to see if things still persist.

  • New ipad skips letters when typing

    When I am typing on my New iPad's touch screen, some typed letters are dropped. I hear the key click and I see the key icon darken, but the typed letter is not displayed. This happens in about 1 out of 10 letters typed. I am typing with one finger.
    This does not happen when using the touch screen on my iPhone, just on the iPad.

    Reboot the iPad and see if that helps.
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

  • Keyboard keys not registering when typing quickly or lightly on a new HP2000 laptop

    Hello, I have the HP2000 laptop and my key compresses frequently d not register unless pressed alot harder than normal. This pc is only a few months od and I feel this is not usual. Is there a quick fix or adjustment or am I stuck learning how to type like a caveman with 10lb fingers???

    Well you should not have to press the keyboard extremely hard to get it to recognize your key strokes. Have you connected an external keyboard to see if the issue occurs still?

  • Revolve 810 G1 Keyboard skips characters when typing

    Hi all, Just got a brand new HP Revolve 810 G1 tablet/laptop (12GB memory 256GB SDD). Things are otherwise smooth, but there is extremely annoying problem of keyboard dropping / skipping / losing some of the characters when typing. It appears randomly, not any specific keys or combos. Up till now in this post it has skipped about 10 characters. It doesn't require fast typing, even in the Win 8 start-menu, when searching for an app and then hitting enter to start the app, it might not react on the enter press. This is just an example, letters are missing from anywhere where I type. I type quite fast and know that I am hitting the correct keys. Disabling the touchpad does not help, so it is not that I would accidentally touching it during typing. I have updated BIOS, restored OS to factory state (HP Full Recovery), switching to English OS localization, installed all Windows Updates - no help. This makes working a pain, it's not feasible to chat or type document when you have to backspace all the time to fix the mistakes that you did not make. HP Support Assistant is not finding any more updates, product number is H5F12EA#AK8,WIn 8 Pro 64-bit. I have installed a 8GB SODIMM under the back cover, replacing the included 4GB chip. Will run a memtest overnight. Anybody seeing the same?? tonttuz 

    Welcome to the HP forum, Tonttuz. If you have adjusted the keyboard speed properties, updated the drivers, and done all the usual, thenIt could be keylogger malware - run a deep scan and make sure you are the only watching what you typeIt could be another program slowing down the system and interfering with your input - check the Task Manager and look for "hogs" -- programs that are running with a high cpu / network / disk consumption and stealing resources.It could be hardware - the system is new, but its construction may not be flawless -- Call HP=====================================================================================It could be that the drivers, though updated, are not being read from disk - instead they may be tangled in the memory and not being read properly. You might consider, without any grand hopes of success, applying a Forced Reset: Forced Reset flushes out the persistant boot-to-boot software and driver instructions from memory and forces the system to go back to the disk to read the software and drivers from the disk Operating System. Forced Power Reset Performing a Hard Reset or Forced Reset The Power Reset cannot tell the difference between drivers - it does not analyze a driver or software program before applying it.  It assumes all the drivers and software on your computer belong there. This is a Driver Reset; this is NOT the Windows 8 Reset that installs the Operating System.  This procedure does not wipe out your files nor does it destroy your Windows setup in any way. EXAMPLE:If the driver software on disk is incorrect or if the driver software is corrupt, it will still be incorrect or corrupted after the Reset.If the driver INSTRUCTIONS are tangled, messed up, or there are bits missing from those instructions, then the Reset may fix the problem. Why a Power Reset works to fix some issues: The Power Reset does not install anything on your computer, the Power / Hard Reset does not remove programs or personal data from your computer, and the Power Reset does not change the settings on your computer.  Your data and programs remain as they were before the reset was applied.  The Reset drains out the old program instructions from the memory and forces the computer go to the on disk Operating System to get new instructions. Why a Power Reset might Not Work:If the issue is more than just entanglement, if the "good instructions" on the computer are not good enough -- that is, you need an update, a new driver, or there is a problem that cannot be "untangled", then the Reset will not work. If there is a hardware problem the Power Reset will not work.==================================================================================== If you want to contact HP directly, you may use the following: Contact HP - Worldwide Contact HP – USA - Phone Assistance  Warranty Required – USA and CanadaUSA – Contact HP // Self-Help – Email - Chat  Good Luck!  

  • Why the user experience on Bluetooth keyboard of iPad is different on keyboard of MacBook, especially when typing Chinese characters?

    I am a Chinese in Taiwan, and I use a input method call "Changjei" (倉頡) to input chinese character. And thank for  "Yahoo Kimo Input Method" found in Macbook Pro, so that I can use this method  as same as typing in Windows PC. When I use bluetooth keyboard connect to iPad mini, it has "Changjei" input method also, but the user experience is different than typing in MacBook Pro! I often type the wrong word when typing in iPad, because some words need additional space key to avoid selection ( when selection appear usually need additional number key for selection ). Usually every chinese character only need one space key for confirm, and in iPad, some Chinese characters need two space key(this will cause problem), and others need one as usual. It slow me down greatly, and is not a smoothly and freely experience when expressing my idea by typing in iPad, and I often distract by these misleading situation when typing.

  • Macbook Pro switches order of letters when typing fast

    Attention: If you seem to make more mistakes when typing on a macbook pro, it's probably not your fault. Letters get switched around.
    This is a problem that has been exhibited in macbook pros as early as 2007 and still apparent today. I could never prove for sure it wasn't me making the mistakes, but today I came up with a consistent test case to prove I'm right. Right now using macbook pro retina display. I noticed this today when every time I typed the word "front" it would come out wrong and I'd have to correct it.
    How to reproduce:
    -In an extremely swift, rolling motion (lasting no more than a tenth of a second), type the letters "fron". The left index finger goes on the f, the left middle finger goes on the r, the right ring finger goes on the o, and the right index finger goes on the n. Since all the fingers are different, it is easy to type the 4 letters extremely fast. You might notice that conventionally the left index finger is supposed to type the letter "r", but people who are good at typing always subconsciously make small adjustments to fingering which improve typing speed/efficiency, so this is a common practice. In this case, I always automatically use my left middle finger for the r in "front" without even thinking, because optimization of typing speed has become second-nature to me, just like you would type "lol" with two fingers rather than cumbersomely all 3 letters with the right ring finger.
    -The fingers should all stay on the keys and keep them depressed throughout this 1/10 of a second typing motion; this is very common in fast typing and has never been an issue in other computers (it would be ludicrous to expect fast typers to meticulously lift their finger up after every letter and make sure there were never 2 keys depressed simultaneously. If there is ever any overlap between keys being pressed, the key that was pressed first should appear first on the screen, not randomly jumbled order)
    -You will notice that even though your fingers landed in the order of "fron", what comes out is usually "fnor" or may even be missing some letters.
    -This is reproducible while typing inside any application

    That is normal. You have to keep objects that have magnets out pf the palm rest area of the computer.
    From Apple:
    Macbook Pro goes to sleep when stacked.
    “Placing a device that contains a magnet (such as an iPhone) under your computer or on its palm rests can cause the computer to sleep unexpectedly. This can also appear to cause the computer to have difficulties starting up”.

  • I am unable to control my iPad 2. It is generating random letters when typing and when I try to delete it generates more letters unless I go slowly! Any advice?

    I am unable to control my iPad 2. When typing and deleting it generates random letters! Any advice

    Start with this and see how it goes. Quit all apps completely and reboot the iPad.
    Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

  • Missing letters when typing on Satellite M105

    I am using a Satellite M105-S3084 (Windows XP MCE) and have been unsuccessfully struggling with a keyboard problem since I first bought it. I tend to type fast, especially double letters and find that very often only one of the double letters shows up on screen. For instance "kk" would result in "k" only and similar missing letters even if not doubled. This causes a lot of wasted time correcting what I type.
    I know that there are settings under Control Panel\Keyboard ("repeat delay" and "repeat rate") that permit setting speeds, but I have found them frustrating to use. I've tried both at various settings and still have a problem with missing letters. Maybe I just do not know which way to set which setting and I am just getting frustrated, or there is another setting somewhere else whic I do not know about.
    Have others had this problem with mising letters while typing and found a solution?
    Thanks.

    Hello Jeff
    If I am remembering well there was similar issue with Satellite L10 or L20, I can not remember. This was fixed with new BIOS version. US notebook models are not known to me but if you have time you can check Ask IRIS on US Toshiba page. There you can find many interesting documents.

  • Compaq Presario CQ56-219WM keyboard frequently misses letters when I am typing

    When I am typing on my Compaq Presario CQ56-219WM I frequently miss letters and spaces.  I have a USB keyboard plugged in, but the missing letters happens on both the laptop's keyboard and the USB keyboard.  I did not notice this issue happening before I installed a Plugable USB 2.0 Universal Laptop Docking Station.  However, I am a bit baffled since this problem happens even when the docking station is not connected and I am just using the integrated notebook keyboard.   
    I use Windows 7 Home Premium. 
    Would someone be able to tell me what to do, if anything, to resolve this issue?  It's really frustrating to have to constantly spell check to try and catch the errors!

    Hi MrsJP. Try updating the BIOS in your notebook. Go to this link http://goo.gl/rk8CV and select which version of Windows 7 you are using and click next. It will display all downloads available for your notebook, including the BIOS update.
    Here http://goo.gl/wTZr6 is a document that will hopefully answer any questions about finding and updating/installing your BIOS.
    Please let me know if this fixes your issue or if you need anything else.
