Portege R500 - ctrl keys have stopped working

Hi,
Both control keys have stopped working on my laptop. The fact that it is both of them suggests that it is not anything physically wrong with the key. I can't do any ctrl+letter e.g. copy, paste, select all, or even ctrl+alt+del
Can anyone suggest how to get these keys back?
Many thanks
Angus

Hi
Any key combination which would disable the CTRL buttons is not known to me.
But I recommend checking the common keyboard options like FN+F10, FN+F11, FN+F12, Capslock, etc
Furthermore you could test the notebook with an external USB keyboard.
If the CTRL buttons would work using external keyboard, then this issue would be related to hardware problem.

  • Portege R500 - Ctrl Key not working

    Hi Guys
    I have two toshiba portege r500 which have never really be used since purchase about 2 years ago.
    Today I get one out to start using it and find the ctrl key is not working which I thought was strange.
    After a little browsing I could not find a solution so I simply got the other identical laptop out and starting using that only to find the exact some problem.
    The laptops are both running XP.
    One of which I have reformatted and uninstalled the keyboard driver to see if that would solve the problem but it did not.
    Any others. Many have suggested that it may be due to a damaged keyboard cable but I think it would be highly unlikely that they would both break in the same way.
    Thanks in advance

    Connect an external USB keyboard and check if the button would work.
    If the button can be used with external keyboard then the internal keyboard is faulty and needs to be replaced.

  • CTRL+H and CTRL+B have stopped working for Firefox. Every other CTRL command works. What's wrong and how do I fix it?

    Whenever I want to open my history (CTRL+H) or my bookmarks (CTRL+B), I use those commands. They've always worked. Yesterday, they mysteriously stopped working. Every other CTRL+KEY command still works flawlessly.
    I haven't done anything out of the ordinary in the past few days, and I've already tried to restart my computer. What could be the cause of this?
    Thanks.

  • Portege R500 - fingerprint utility has stopped working

    I have a Portege R500 laptop. The fingerprint utility has stopped working. First (perhaps after an update of the True Suite Acess Manager was installed a few months ago) it failed to work on login but did work for other passwords.
    Now it doesn't work at all. If I try to register fingerprints it tells me that it has failed to locate the sensor. I have reinstalled the AES1610 driver and the TrueSuite access manager, but it makes no difference.
    In Device Manager it says that the device is working. I have looked at various threads on this without seeing anything that works.

    Hmm Maybe you should try to clean the registry after the fingerprint software has been uninstalled.
    In your case I would follow this:
    - uninstall the fingerprint software and delete the fingerprint device from the device manager.
    - reboot the notebook
    - clean the registry using the free tool called CCleaner
    - reboot once again and install the software and driver
    - reboot once again and test the fingerprint functionality

  • Portege R500 - Toshiba Flashcard has stopped working

    Hi,
    I keep getting this "Toshiba Flashcard has stopped working and will closed down" error when I start up my Portege R500 laptop.
    What is causing this?
    I'm running in Vista and my PC continues to work even though it does this.
    Cheers,
    Elty

    Hi
    Its not easy to say what causes this issue.
    In most cases some other software parts could affect the functionality of different applications.
    For example my flash card stopped working after Vista has ran some updates.
    I have simply removed the old VAP (value added package) from the system.
    I cleaned registry and system using the CCleaner (free tool) and then reinstalled the VAP again.
    Now everything is running properly.
    I think you should try the same too.
    Remove the VAP and install the new VAP downloaded from the Toshiba European driver page.
    Check it out!

  • Help...just updated to Tiger and some of my keys have stopped working!!!

    Hi
    I just updated from 10.3.9 to Tiger 10.4.3 and some of the keys on my key board dont work any more...
    Caps Lock, Plus & equals,right arrow & up arrow???
    Does anyone have any suggestions???
    Cheers
    Adam

    Hi Adam,
    Have you run Repair Permissions and "Verify Disk" from Utilities/Disk Utility?
    If not do that. If "Verify Disk" reports errors then Repair Disk from Tiger Install disc.
    Then use the 10.4.9 PPC Combo Update.
    This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before. It has worked well for many.
    Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
    Let us know.

  • Two keys have stopped working, whhy?

    Two keys stopped workimg on my laptop with snow leopard. I rebooted the system but the keys still don't work. So now i can't get past login.

    A temporary solution would be to use an external keyboard.

  • The letter keys on my MacBook have stopped working and the trackpad (or external mouse) are treating a single finger click as a double finger click

    The letter keys have stopped working on my MacBook. Number keys and punctuation keys seem to work fine. Also, the trackpad treats a single finger click as a two-finger click. I tried an external mouse and this does the same.
    If I restart, the mouse works fine but after a few minutes the issue starts. I have looked at a few forums and have checked the settings under system preferences but nothing jumps out at me :-(
    Any ideas???

    Is this one of the MacBooks with a removeable battery? If so, try removing the battery and restarting the MacBook (obviously while plugged in to an AC adapter) and test to see if you still have this issue. Other users have reported that swollen expanding batteries have caused keyboard and trackpad problems.
    If that isn't it, let us know, we'll keep helping you.
    Best of luck.

  • Shift key just stopped working...

    both of my shift keys have stopped working. they are working sporadically, and i'm not sure what happened. i was typing and suddenly my shift button would not work. i know i didn't hit some sort of hot key to disable the shift function, and it seems that the buttons will randomly work or not work, without hitting anything. is it possible that i have disabled them, or that there is a bug in my computer that is causing this to happen [i hope not, as the guy taht sold me my computer told me not to buy virus protection]. any help would be greatly appreciated, and i'm sorry for the all-lowercase post.

  • All physical keys on my torch 9800 have stopped working

    this morning I discovered that every single physical key has stopped working. I've tried restarting via battery pull. How do I fix this?

    There ya go.
    Why now?
    Go put a slightly damp napkin on a nice piece of wooden furniture.
    Remove it within five minutes, no damage.
    Now, leave it there for three days and tell me what the wood looks like?

  • A certain set of keys randomly stop working in a Flex application

    My company has a Flex application (version 4.5.1), and certain keys will stop working from time to time when typing in a TextInput (the MX variety).
    Each occurrence has been on a Windows machine.  I have noticed it in Internet Explorer 11, using 15.0.0.152 (developer version), and co-workers have noticed it on other versions of IE (I don't know which Flash Player versions they were using, but they weren't the developer versions).
    About the only major change I can think of that may coincide with this issue would be having to convert a Google Map from using the Flash API to the JavaScript API.
    The keys that have stopped working are: k, m, !, #, $, %, &, (, -, _, =, +, ', " (capital "K" and "M" still work)
    I can still paste these characters into the text box even when the keys aren't working, so it's not an issue with the text box not accepting the characters.  I can have the application open in multiple tabs and have things working normally in 1 tab but not the other.  I have seen the keys stop working and start working again without refreshing the tab.

    Understood.  We have an extensive set of automated regression tests, and in the rare instances where we do break text input, it's an on/off thing.  This is super interesting because it's so weird, but I have zero theories about why it might be happening.
    If it is a Flash bug, there's probably a really long sequence of steps required to get it into a wonky state where this would occur, and the only way that we would figure out what's going on would be to reproduce it under an interactive debugging session.  I'll ask around, but I've been working on the engineering team since 2006 and I've *never* seen this.  I really like crazy stuff like this, but I've got nothing...
