Compaq CQ60-104TU keyboard not responding

Hi experts,
I have been facing this problem of keys not responding or responding in erratic fashion on my Compaq CQ60-104TU laptop. Because of this I'm not even able to login into my system.
Can somebody please point out to the problem and also the solution.
Thanks & Regards,
Himanshu

as far as i know, if you can type in your password on the log-on screen then the keyboard is working, if the problem would appear after logging in or it will appear when you are on your desktop screen then it may be an operating system problem or a user account corruption issue
the keyboard would only be a hardware failure if when you turn on your nb, there will be no ligts on teh keyboard, capslock key will not lit or no response at all from the moment you turn on the nb
for the touchpad, try to check if its off or on... if there is an orange light above the touchpad then its off, toggle the switch on that light to turn it to blue..
so before anything else.. TRY THIS FIRST!!!!
1. remove the battery
2. disconnect  the power adapter
3. with no power supply at all, press and hold the power button for 1 min.. make sure it will be 1 min...
in technical terms we call this HARD RESET.. this process would release static charges that might be contained on the power button bec sometimes those static charges causes harware malfunctionalities..  
then it this step will not work.. do this...
try to go to safe mode by continually pressing F8 when booting (press F8 when you see hp invent screen), then you'll be directed to advance boot options... choose last known good config.. then it will boot to last known good settings....
please let me know if this will not work..
if not "choose repair your computer" on the boot selections.. choose keyboard layout as US.. then if asked for a username and password.. you can cahnge the administrator username to  your username then put in your password.. if you are not using any password leave it blank.. then choose start-up repair...
please let me know if this will not work..
Hope this helps.....................

    updated iphone 5 to iOS 6.1.3, now I am having trouble with keyboard not responding correctly and screen zooming in by itself...
    Buttons pressing themself...
    Also, my main screen is permanently zoomed in...
    suggestions?

    Double tap the screen with THREE fingers, that should get it back to normal again.
    Then go into Settings > General > Accessibility > Zoom > OFF.
    Not too sure about the keyboard and random button presses though.  Back it up and restore from iTunes, see if that fixes it.

  • After "sleep" keyboard not responding, mouse is working ok (mouse is wireless, k/board is not)

    after "sleep" keyboard not responding, mouse is working ok (mouse is wireless, k/board is not)

    Probably a defective keyboard.  I had that problem a few months after I got my Mac Pro.  Apple replaced the keyboard and it has worked fine ever since.

  • USB mouse and keyboard not responding

    I had a power outage yesterday and my iMac was on. I have since tried to start it and my keyboard and mouse are not responding and I get a message that the date on my computer has gone back to before March of 2001. I need help, my hardware warranty just expired and I really don't want to take in it and have to pay $100! Also I put in my start up CD and now I can't get it to eject. Please HELP!!!!!

    Does the keyboard and mouse work after the computer boots up? Try unplugging them and plugging them back in. Make sure to plug them in directly to the computer. If it still is not working try the mouse and the keyboard separately one at a time. Look to see is the caps light comes on the keyboard and look to see if the mouse lights up. To set the date and time go to your System Preferences/Date & Time and put a check in the box that says Set date and time automatically(assuming you are connected to the internet). If you can get this far go to System Preferences/Startup Disk and select the install disk as your startup disk and click restart. When it boots up to the disk, instead of going through the installation, click on Utilities at the top and run Disk Utility on your hard drive.

  • Keyboard not responding while installing Windows XP sevice pack 2

    Hi,
    I am new to macworld, Just got Macbook and try to use bootcamp to install windows xp, but keyboard did not respond hence got stuck at this point. Please help me. how to make keyboard working while installing windows xp using bootcamp. I know that for non-portable Mac USB mouse and keyboard can be used but whats need to be done for portable Mac like Macbook

    I have been scouring the internet on my limited dial-up connection trying to find someone who had a definitive solution to this problem which I too have been stuck with.
    What finally resolved this keyboard problem during that critical stage in the win xp setup was by:
    1. Going to System Preferences>Keyboard and Mouse and check-marking "USE ALL F1, F2 ETC. KEYS AS STANDARD FUNCTION KEYS (when this option is selected, press the Fn key to use the special features printed on each key)" Before starting up Boot Camp,
    2. and Unplugging the Mighty Mouse from the keyboard while my mac was rebooting.
    Switching out the apple keyboard for a standard USB keyboard did not work (perhaps in hindsight, i should have plugged it in first before boot camp rebooted and tried to install win xp;)
    Attempting time after time again did not solve the issue;
    Neither did doing all the software updates, firmware updates and such while borrowing an ethernet cable connection from my local library;
    I did not need to find another Win XP with SP2 nor did I need to find a USB keyboard;
    Not even updating my Mac OS X from 10.5.2 to 10.5.5 or installing the new firmwares for the Apple aluminium keyboard was necessary it seems.
    Just a simple checkmark to make the apple keyboard's F-keys primary and unplugging the Mouse from the keyboard before the WinXP install kicked in, allowed me to press Enter to proceed with the installation.
    I also turned off the special functions of the mighty mouse like the center click and roll ball, but I felt obligated to post the solution to this problem - Do as you would be done by.
    Hope this helps others who encounter this same problem, please confirm if I am correct. Good luck.

  • IBook G4 keyboard not responding

    My wife recently spilled some water on the side of her iBook and now when she hits the keyboard it is not responding anymore. Is the keyboard that sensitive to water? Is there a way to test whether it's the keyboard or the connection? If it's the keyboard any recommendation on where to buy one?

    The chances are, the water has damaged something in the keyboard.
    It would take a vast amount of water to run down into the logic board. By the suggestion in your question, it's only a small amount. Keyboard are very easily replaced and could be brought secondhand working on eBay very cheaply. Make sure you buy the right keyboard for your model and screen size. A 14" iBook keyboard wont fit a 12"  iBook keyboard.
    Best of luck

  • MacBook Pro Retina Keyboard not responding after Sleep

    Hi,
    I am having an issue that I have noticed in Mountain Lion. When I put my MBPr to sleep, either via Apple->Sleep or by Closing the lid (maybe sleep for 5-10 min or more); the Keyboard will not respond at all and cannot enter the Password to get back in.
    I have tried to remove the lock screen in order to avoid that but the same things happens for any App that I try to use and requires keyboard. The Apple Magic Mouse works fine, and I have no external keyboard connected.
    I have taken it to the Store and the ML was re-installed...still same issue
    Anyone had this happen and able to determine the cause?

    Just some more info regarding this:
    Pressing a key on the usb key board will bring up the log in screen and the mouse works (plugged into the keyboard) but text input from the keyboard doesn't work.

  • Water spilled, keyboard not responding

    Hi,
    **** happens and I spilled water(not so much) over a 2 months old Macbook.
    I took hair dryer, i removed the back plate (as for replacing RAM), dryed everything for a moment (I didn't want to remove mother board, so no direct line to keybord). Now the situation is that everything works very good except that the keyboard is not responding (not a single key, when I say everything works perfect it is when using mouse or trackpad). Ok I know that if it does not restore (by some miracle) it has to go back to Apple. Is there any way to see if it is just the connection between keyboard and mother board that is affected (still not dry) and it would not require sending it back?
    Cheers

    yeah, powering it up without being 100% sure it was completely dry wasn't good. depending on how long ago this happened and the relative humidity and temperature of where you most frequently use and store the laptop will determine if it's completely dry.
    it is likely dry, but water has minerals in it that can interfere with electrical contacts once the water evaporates and the minerals are left to dry onto the exposed electronics. this could very well be the problem and all you MAY have to do is clean any contacts you can see mineral buildup and/or corrosion resulting from the spill.
    or, what is also likely, is that the keyboard controller has shorted.
    is the keyboard's presence recognized in system prefs or system profiler?

  • TS3048 wireless keyboard not responding after sleep mode

    My Apple Wireless keyboard (old style with numeric keypad) does not respond properly when my computer exits sleep mode.  Keys either don't work or a single key hit produces multiple letters / numbers on the login box. The only way to get the keyboard to work properly is to turn it off, wait until the computer says it's lost the keyboard connectilon, then turn the keyboard back on again. 
    I tried a newer Apple Wireless Keyboard (current model) with this computer, and it works properly. 
    Anyone have an idea as to what's going on here?
    Thanks

    ** SOLVED ***
    If you have a early 2011 MBP, the optibay SATA is a 6GB bit is really support 3GB/s only.
    If you have a 6GB SSD, install it in the ORIGINAL adapter and the original SSD in the optibay.
    This will **SOLVE** the issue.

  • Keyboard not responding before boot

    Hi,
    My USB keyboard does not respond at all before the OS boots. This means that I cannot access the bios, not can I chose which OS to boot in Grub (it is set to automatically boot in Archlinux with a timeout of 5 seconds). But my keyboard works fine after boot, as I'm using it now...
    This behavior only started about three months ago; before that there was no problem. It seems like the USB-function is disabled in the BIOS, but since I cannot access the BIOS I cannot verify or change this. And I cannot attach an old PS2 keyboard, because the computer (Dell Dimension C521) has no PS2 port, only USB.
    I have the suspicion that the computer is too old and that something hardware-ish started to malfunction. But perhaps someone here has an idea how to fix this?
    Thanks,
    Roger

    Adds USB HID modules to the image. Use this if you have an USB keyboard and need it in early userspace (either for entering encryption passphrases or for failsafe mode).
    If he's not getting access to the keyboard in the BIOS / Grub screen; then it has nothing to do with a kernel module that is loaded after that.
    Argh, you're right + the usbinput is now included by default http://mailman.archlinux.org/pipermail/ … 01116.html

  • Bluetooth magicMouse & keyboard not responding after sleep mode

    Hello,
    I recently upgraded from Lion to Mavericks (10.9.1).
    A very annoying bug happens every time the macbook pro exists from sleep mode.
    In this situation, when the mac wakes up, Bluetooth devices (magic mouse & wireless keyboard) do not respond. Since I am using the mac in clamshell mode with external monitor, this is very annoying because I have to open the laptop, and turn on/off Bluetooth manually.
    Sometimes the same problem arises for the internet wifi connection, which do not reconnect.
    I am very surprised of this bug.
    Does anyone have the same issue?
    I was thinking to do a clean installation, as suggested in some posts, but I don’t believe this will solve the issue.
    This issue HAS NEVER APPENED in Lion.
    Thanks for support.

  • Keyboard not responding after OSX 10.7.4 update

    I have just installed the OSX 10.7.4 update.
    About 12 hours after installation the screen dimmed with a message that I need to restart the computer. I did so and now after startup I get a message on the screen that the Bluetooth keyboard can't be found. I actually have a hard wired keyboard, not a Bluetooth one, but there is no response to keys on the keyboard and I can't get rid of the screen message, even after a restart.
    So I can't start in safe mode or anything like that because the keyboard doesn't work. Any ideas on how to get around this?

    Thanks for the suggestions, but the keyboard was connected to a built-in port.
    When I came back to the computer about an hour after the problem appeared, the bluetooth message had gone and the normal keyboard was working again, so I could log in. I checked Bluetooth in System Preferences and found there was a "phantom" wireless keyboard listed, that I had never installed. I removed that from the list so hopefully the problem won't re-occur.
    Not sure whether this problem was related to the update, but from other posts, it appears to have caused a number of issues.

  • Dual G5 frozen even after restart. Mouse & keyboard not responding.

    Regarding older Dual G5...recently began using after updating to latest compatible OS ( 10.5.? )...left for dinner... returned to unit frozen, tried re starts, no results...mouse or keyboard not responsive.. have done several re-starts, hard re-starts ( unplugged all ), changed keyboard and mouse, disconnected any 3d party devices... Full screen comes up, window about conflict with "Suitcase"comes up, but keyboard & mouse do nothing???...Clif

    Hello,
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed. Or an errant process eating up RAM.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...
