  • My laptop touchpad left mouse key not working

    I have a Elitebook 8440p with windows 7 professional.The touchpad left mouse key not working ,but right mouse key works well.my driver is  synaptics 14.0.10 090ct09 and the touchpad name is synapticsTouchPadV7.2.
    thanks in advance.
    wy

    i had the same problem. what solved this for me was to simply go to device manager and under mice and other pointing devices uninstall the touchpad, i had a usb mouse handy just in case i needed it, but then i restarted the laptop and it auto reinstalled touchpad for me and then all options worked on startup.

  • I have bought  three iPhone 6  one for me and one each for my two kids  we have just done the update iOS 8.01 now all phone  do not connect to service provider and touch id is not working ,  APPLE HELP !!!!

    i phones  updated iso 8.01 all three phones  will not connect to service provider and touch id
    will not work  APPLE HELP !!!!!!!!!
    anyone know  i fix as  i have spent over 2000 pound on three phones that won't work
    all three where working fine until the 8.01 update

    Apple just pulled the update because it is a major fubar! You will have to rollback your iPhone to the base iOS 8 using iTunes and Apple needs to seriously test its patches!
    Update:
    Simply connect your phone to iTunes and back up your data. Then, click the “Restore iPhone” button and follow the on-screen instructions. It’s a huge pain, but at least it’s better than having your shiny new iPhone turned into a big expensive iPod touch.

    What do you mean "not working"?  That could mean multiple different things.

    Activation issues are almost always the result of a device that has been hacked or jailbroken.  If that is the case, no support can be provided here.

  • Command key not working and clacking when touched

    My left command key just stopped working. When I press the key, even just barely tap it, it makes a faint "clack" sound- (especially on the edges of the key). It is only the left command key and does not work for ANY function. Any ideas as to what could be wrong???

    Are you sure you are using Command+C and Command+V.
    Works fine on my MBP Lion 10.7.2 in all applications.
    You could also try using the Space bar and the Shift and Enter/Return keys when asking a question.

  • Up and Down Arrow Keys Not Working

    I have had the HP Pavilion g6t-1b00 CTO Notebook PC for a year or two now. I've been having a couple of problems with internet connectivity and putting my computer on "sleep".
    However, few days ago, my keyboard randomly started acting weirdly. When I would try to type certain letter/numbers, they would come out differently. 
    Ex. pressing the space bar would show up " ./M" instead
    I tried restarting my computer many times and installed a BiOS update which fixed all of my issues except for my up and down arrow keys. As of now, they have no function; I can't scroll with them and they don't seem to be taking on the role of another key. I have tried using the keys on different programs. Using the touch pad to scroll works but I still can't use the up and down keys.
    Is there anyway to get the up and down arrow keys to work again?
    This question was solved.

    Hello Larasoft,
    I understand you’re up and down arrow keys are not functioning, is that accurate? I will do all I can to help you with this issue.
    I want you to access the setup menu to test the keys out, see instructions below.
    1.       Shut down the computer.
    2.       Locate the F10 key across the top.
    3.       When you turn the computer back on immediately start tapping the F10 key repeatedly.
    4.       If successful you should be on setup utility screen. What’s different about this is you can only use you arrow keys to navigate.  
    5.       Try working the arrow keys  up and down on different menus and see if they work.
    6.       Once you tested it press F9 to setup defaults and then press F10 to save and exit.
    If I have been helpful or if you’d like to say thanks you can click the white star under my name to give me Kudos.  I really appreciate it.
    Please respond at your earliest convenience with you results.

  • Help! Left shift key not working!

    all of a sudden today my left shift key has ceased to work. the right key works fine, increasing the chance that it's hardware. I'd like to remove the key cap and see if re-seating it might fix it. I've looked in many places on how to remove it, but no luck. Is there a web site that shows how it's done for a G4 Aluminum? Thanks in advance.

    Marco,
    I've been having intermittent left shift key problems for several months. My laptop is now 3 days out of Warranty, Apple web site says so. Anyway, the only reliable fix I've found is to do a re-boot. I can also (sometimes) get reliable shifting if I slide my finger closer to the outer edge - meaning, no shift if pressed on one side of the key, sometimes shift on the other side.
    I've also had success shifting in one application which seemed to "clear" the problem in the original application. Example: typing in Mail when left shift key stops working. Switch to MS Word, shift works fine. Switch back to Mail, shift works fine.
    I have a feeling it's a combination of software and slowly failing hardware. I feel bad to have waited until after the warranty period, and now the problem is getting worse. My wife was just in for brain surgery, so you can't really blame me! She's doing fine.
    So, my suggestion is to try rebooting to see if that clears a memory buffer problem. Kinda annoying, maybe a future software update will fix the software problem?
